Maintenance practical weekend blogLaura Hill and AyssaLaCroix

October 26-28, 2012

This weekend was difficult but educational. We didn’t have the best weather which made the tasks we were given harder to accomplish but we did the best we could with what we were given. Friday, our number one priority was to get the tree planting equipment ready for the first years to plant their class tree. We demonstrated and helped plant the tree properly and after they were done we added extra mulch and watered the freshly planted tree. We then moved on to planting our own tree, the Oxydendron arboretum, or sourwood.

We properly staked, wrapped and protected the tree with a tree guard then mulched the tree with the proper technique and watered it.

 

Once we had completed the tree plantings, we started working on trimming back the Hemerocallis and Hostas in the Louise Weekes gardens, along with any other perennials that appeared to be spent. The dutch hoe was used to weed the rest of the Louise Weekes garden andwe soft raked the weeds out and disposed of them once the dutch hoe had gone over everything. Next we mulched the freshly weeded areas and collared the trees in the area properly.

At the end of the day we took all our plant waste to the compound, washed off our tools and put them in the tool room, then put the RTV back in the tractor bay.

Saturday our priority was to get the bed across from the Louise Weekes garden mulched, edged and weeded.

The weather on Saturday was terrible, very rainy and windy, so we did the best we could with edging but our biggest challenge was having the edge sink because of how wet the soil was. We did the best we could with edging, and moved on to using the dutch hoe to get the weeds out of the bed. Once we had finished weeding we mulched the area using four tractor loads of mulch and spread it throughout, we had a bit of extra so we mulched a few areas in the Louise Weekes garden.

Once we had finished that we went over to R1 and dug up 30 of the Gazania ‘New Day Orange’ and potted them up for sale. For the rest of the day we did our best to weed the R1 beds.

Sunday our focus was the G sub courtyard. Our tasks were to weed and edge the beds, remove the cedar and add tree collars to all of the trees, but like the entire weekend, the weather was against us, it was raining and very windy. We began by removing the cedar from next to the door as it was brown and dead.

Once we removed the cedar we proceeded to add tree collars to the trees and weed the interlocking pavers that led to the center of the circle. We also did our best to weed the beds with the junipers. We tried to edge but the soil was just too wet and uncooperative.
We then went back to the Louise Weekes garden to divide the Pennisetum by the Acer pseudoplatanus ‘Eskimo Sunset’
We then did our best to clean up our work site, and our equipment. We power washed the RTV and the John Deere tractor and hosed down our tools and swept the tool room.
All weekend long we did our best to clean up after ourselves and get as much done as we possibly could. The weather was definitely against us, but it was a productive and educational experience none the less!

Bulb Forcing!! During our weekend practical, the most important job was planting the Tulip and Hyacinth bulbs in preparation for over wintering. We kept the bulbs in the fridge so they would stay cold before planting. The over wintering process started with 6 inch azalea pots, bulbs and ProMix. Each pot was filled to the height of the bulbs so the tips of the bulbs could stick out of the ProMix and prepare for the winter climate.

In preparation for the bulbs, we had to prep the cold frame boxes in the tractor bay storage area. We re-levelled the ground out a bit better to make it even for the pots to sit on top of. We started off by putting 3 tulip bulbs in each pot until Mike showed up and told us we were doing it wrongL!!! This took us about an hour to correct our mistakes. He also said that if there were too many to correct that we could leave some of the tulip pots with 3 bulbs, so we did. He explained to us that each Hyacinth pot should have 3 bulbs because they are larger than the tulip bulbs, and the tulip pots should have 6 bulbs, 5 surrounding the outside of the pot with the fat side out and one in the center so it makes a full pot when they bloom. The reason for putting the bulbs fat side towards the outside of the pot is because the first leaf of the plant will sprout through that fat side! This is a very important process and we want to make it easier for the bulb to sprout! After all the bulbs were planted, they were labelled and watered. We did not over water the pots but we did give them ample amounts of water and left the tops of the cold frames off during the day while it was raining (Mike said that was okay).

 To stop the bulbs from being damaged or eaten by rodents, we added 2 rodent traps to the cold frames. We used a rodenticide called Ratak+.

They are small blue pellets that the rodents eat and die after one feeding.

Weekend IPM Blog

October 19-21, 2012

Laura and I were asked to release half of the biological controls into the greenhouse, this included 25 Biobest cards, and 25million Nematodes. The Biobest cards contain the larva of Eretmocerus eremicus and Encarsia formosa, these are both considered to be parasidic wasps that attack 2 different types of whitefly. Encarsia are the black larva and these hatch and attack the greenhouse whitefly, while Eretmocerus attack the silverleaf whitefly. The Nematodes were being released to control the fungus gnat problem. Both of these controls are to be stored in to refrigerator until they are ready to be used, this is because the Biobest cards will begin to hatch when exposed to the temperatures in the greenhouse, and the nematodes will become useless if they are heated to room temperature.

 Friday we observed the Biobest cards before placing them throughout the greenhouse to see the before image of  the larva.

Friday was also a good day for us to apply the nematodes, we concluded this based on the information that the media would need to be fully saturated for the nematodes to activate and function properly. We mixed 25 million nematodes (half of the container) with 10L of temped water, and stirred the solution continuously, this is also an important step to ensuring that the nematodes work properly, we applied 20ml of the nematode solution to each poinsettia.

Saturday we decided to pull a few of the Biobest cards off of the crop to observe if any of the larva had begun to activate, in doing this we found that some of the Eretmocerus had begun to emerge where as we were unable to find and specimens of the Encarsia emerging. We took a few pictures of the Eretmocerus emerging.

We then began our search of the sticky strips in hopes of finding both whitefly specimen’s, we found a greenhouse whitefly and a silverleaf whitefly on the sticky strips.

We then did research on symptoms of whitefly and found that suckering of leaves can often be caused by the whitefly eggs, we pulled a few leaves that had these symptoms. Using the 140x camera we found both freshly laid and mature eggs of the greenhouse whitefly, we concluded that that white to transparent eggs were freshly laid whereas the mature eggs are brown or black in colour.

Finally the biggest moment in our IPM research was finding a pupa of the silverleaf whitefly on the backside of a ‘Polar Bear’ leaf. The bug book described the pupa as being yellow/transparent with red eyes, often found in a profile view, where as the greenhouse whitefly pupa has a more flattened appearance.

In the end our opinion is that the biobest cards would most likely work a lot better if storage is made a priority because if they aren’t it degrades the quality of the cards, which in turn affects the number of pests present in our greenhouse.

Furthermore we feel that there needs to be a better way to add the 20ml of nematodes to the pots; using measuring cups does not allow the distribution to be exact, which again affects the number of pests we have to deal with.

We also can confidently say that both types of whiteflies are still present in the greenhouse.

Fall Clean-up

Friday, Oct 19, 2012

            A cool and windy morning greeted us Friday as we began out weekend practical. Upon arriving at the greenhouse we were informed that the tractor and trailer were going in for repair and servicing therefore the all important fall mulching would be put off for another weekend. Instead we were tasked with cleaning up and weeding the Louise Weeks garden, with some minor work in the Woodland Garden.

Ribes Hedge

            We started by cleaning up an overgrown Ribes odoratum hedge. The Ribes hedge at the Fanshawe College Gardens can be found bordering a sidewalk near a parking lot outside K Building. Grown as an informal hedge, it is uses a transition plant between the parking lot and the Woodland gardens. Suckers are a troublesome problem with Ribes they send up multitudes of shoots through their expansive root system. Using a spade we dug/cut out numerous of these suckers, found growing inside or some distance away from the original planting line. Due to its location our hedge had become sort of garbage trap. Not only did we spend all afternoon fishing out garbage, but dead plant material, and of course leaves. Using loppers and secretors tasked with the awkward trimming of the over grown hedge. Doing our best to make our cuts invisible to the pedestrians, as well making all sections of the hedge the same length we pruned the hedge back.

            We woke to a wet morning, and another daunting task. The Louise Weeks Garden, comprise, of deciduous and coniferous trees, broadleaved evergreens and many different varieties of herbaceous perennials required major work. While Nick attacked a garden bed filled with bindweed, I took on the project of cleaning up a group of Cirsium diacanthum (Ivory Thistle). This self seeding perennial is slightly invasive due to its habit of spreading through seeds and rhizomes, it's sharp, thorns makes it a slightly problematic plant to deal with. Nick continued to rage war against the bindweed, discovering even with garden forks and shovels it was hard work removing every last bit of it. While many perennials weren't looking their best a few unique things were happening around the garden. A Hamaelis virginiana (Witch-Hazel) was in full bloom, its unique blooms contrasting against the dark bricks. The perennial grasses were in full bloom, billowing in the wind and giving interest to the otherwise empty beds.

            On our last day, the priority remained on digging up, diving, and replanting a Miscanthus grass, and more weeding, raking and cutting back of the perennial beds. The task of digging up and dividing is harder than it sounds. Division of perennials is an old way of plant propagation. For perennial grasses, it is the best way to get true to type plants. Using a spade and shovel, this task was accomplished. Suckers continued to be the biggest weed within the garden. Even the Hamaelis and the Sumac sent up tiny shoots through the mulch. Cutting the larger suckers, and hand ripping the smaller ones became the most efficient way of eradicating every bit of the plant. We ended our day, by raking up any left over debris and leaf blowing the side walk clean.

Friday, October 12, 2012:

A beautiful day to start off an otherwise rainy weekend garden maintenance practical. We reviewed our tasks, asked questions while we could, and took many notes when special instructions were given. As we reviewed our tasks, we began to develop a work plan for the weekend by prioritizing what work could be done in the most efficient manner. We did not know that our plan would soon have to be revised; while circle checking the Kubota tractor, we discovered that the lights were not working properly. This is a great example of why circle checking all equipment before use is very important. To maintain our goal of efficiency, we began weeding and editing the Woodland Garden while the lights on the tractor were being repaired.

Saturday was a soaking wet day, which was disheartening for us but good for the conifer garden. With winter approaching the conifers need to be supercharged so we set up a sprinkler to start the process. Supercharging ensures that the trees are at their maximum water holding capacity which will prevent a moisture deficit when the bright winter sun causes moisture loss from the leaves. In the afternoon it began to rain heavily so we turned the sprinkler off and let nature continue the supercharging.

            The rest of Saturday was spent tidying up the conifer garden and weeding the Woodland garden. In the conifer garden we removed weeds from the concrete pathways and did a quick weeding of all the beds.

In the woodland garden we continued to weed and edit and significant progress was made in shaping the garden up. By the end of the day both the conifer and woodland garden were ready to be mulched.

            The top priority for Sunday was getting the mulch down on the Woodland and conifer gardens. However when we were hooking up the trailer the battery began to smoke so it was deemed unsafe to operate. This meant that mulching was off the table for the day so Holly and Caitlin continued to weedand edit the Woodland garden. It consisted of final touch ups and going over the work that had been done to ensure that everything was complete.  The weeding and editing of the Woodland garden was the most time consuming aspect of the weekend but the garden is shaping up nicely.

Meanwhile, Brandon worked on cleaning up the compound by line rimming overgrown weeds and disposing ofunusable concrete .After lunch, Caitlin and Brandon unloaded the trailer which was full of weeds and debris from the previous two days’ work. Due to the malfunctioning trailer electronics, the weeds and debris were unloaded by hand.

Once work was complete, final clean up was performed. All equipment was washed down including hand tools,  and the backpack leaf blower was used to clear all paths in the Woodland and conifer gardens.  During clean up, the bulb boxes were put on the soil in the holding area with landscape fabric underneath them. Upon performing a final check we discovered that someone had ripped off the branches of the Cersistree that was planted earlier during the weekend.  Hardly any foliage is remaining on the tree

Friday – Sunday

October 5-7, 2012

Friday: We started our weekend practical Friday morning in the greenhouse with Jeff. Jeff helped explain to us what we were to do over the course of the weekend. After our meeting with Jeff we moved ourselves into the tractor bay, where we spent at least 30 minutes signing out equipment and completing the proper circle checks.  We noticed a few key things that we discovered over the course of the weekend that we should have asked Jeff before he left. We noticed that the battery to the trailer works one time then the battery is completely drained. Travis completed the circle check for the trailer and it appeared to work but that was not the case. After all the equipment was signed out we started to pick and remove all weeds and suckers in the gardens. We were unable to get all the suckers due to lack of time.  After the weeding was complete, Jeff assigned Travis to plant the extra trees that were added to our list. While Travis was planting, I was at the front of the school re-tying and staking the Ginko that was added to our list and planting the Tsuga in the conifer garden in front of K building.

 After the trees were planted we moved onto planting the Taxus.

We noticed that it was fairly easy to plant them with one person, so we decided I would cut down one of the Malus trees and Travis would continue with planting. At the end of the day we washed off our equipment and helped Pedro close up shop.  (Cleaning the tractor bay)

Saturday: On Saturday Travis was only available to work from 8-11am, so we decided to get as much mulch as possible before he left. We were only able to get on trailer load down and on a tarp for me to work off of because the trailer battery wasn’t working properly. We put the battery on the charger for some of the day Saturday but it did not work (we used the trickle battery charger). After Travis left I helped Pedro and Josh dispose of their waste at the compound, after that I planted the last Taxus between the burning bushes. After lunch I laid mulch until 4pm then I started to do, my clean up. We were unable to complete all of the mulching due to Travis being absent and the trailer acting up.

Sunday: On Sunday we started off our morning by planting Piceaabies‘Slim Jim’ in between burning bushes in the corner of the conifer garden closest to H café.

After the tree was planted I staked and tied it while Travis went to pick up mulch. When the mulch arrived at the conifer garden, we laid out a tarp and started to hand bomb the mulch out of the trailer due to the battery situation. After the mulch was out of the trailer, I stayed to lay it out, while Travis went to get another load of mulch. Then we took lunch, during lunch we put the trailer on the plug in charger for an hour then it worked once or twice before dying on us again. By the end of the day we finished installing as much mulch as possible, and with our last half hour we started to do our cleanup, take pictures do a walk around for equipment and, make sure all the proper paperwork was completed for the trees we planted.

In conclusion: with the amount of work we were given and the situation with Travis on Saturday we are satisfied with the amount of work that was completed.  We think that if we were together for the whole weekend all the tasks would have been completed.

Over our weekend practical we completed many essential tasks for the Fanshawe poinsettia crop (Euphorbia pulcherrima). The most important task we completed was watering and fertilizing the crop. “the hand that holds the hose controls the crop.”. It was a meticulous job. Poinsettias are in the Euphorbia Family and therefore are required to dry out in-between watering. Over watering can lead to root rot in the Poinsettia. We needed to observe the crop for any plants requiring culture and apply the correct amount of fertilizer, to ensure the crop did not get fertilizer burn.

Some symptoms we were looking for were wilting, browning, crinkling of leaves, a light feeling to a pot compared to a watered one, the media pulling away from the side of the pot or light brown media (as its watered it turns dark brown).

Euphorbia pulcherrima wilting. It could be caused from lack of watering or overwatering causing root rot

 

Euphorbia pulcherrima showing symptoms of requiring water. Notice the media pulling away from the sides of the pot. To ensure the media is water toughly it needs to be applied slowly

We used the Dosatron to apply a 250ppm fertilizer to dark coloured Euphorbia pulcherrima cultivars (Red Glitter, Christmas Feeling, Winter Rose, Christmas Day, and Classic Red). And 300ppm for the light coloured cultivars (Polar Bear, and Poly Pink).

They were watered one bench at a time to ensure the Dosatron and drip lines were working correctly. We tagged the drip lines that did not work to ensure they got watered accordingly and that the lines were fixed promptly.

We took a drip line out of a poinsettia and placed it in a measuring cup to ensure 300ml of water and fertilizer were applied to the poinsettias.

We noticed while watering that the water was not very blue, implying that there was no fertilizer coming from the drip lines. The Dosatron seemed to be in working order and the hose that was used to flush the lines was blue. However, when we checked the other hose in the greenhouse (on the far end) after the Dosatron was “working”, its line also had to be flushed in order to run blue. As per last week’s greenhouse class, the Euphorbia pulcherrima were on par with what is expected as per Ecke “OnTrack” website.

The Euphorbia pulcherrima required no further watering over the weekend, although they were monitored

Browning of the leaves could show signs of requiring water or fertilizer burn.

Pedro and Josh Here!

This weekend was our weekend practical here at Fanshawe College in the greenhouse, We received some new tropicals plants!  Such an exciting day! We received 3 cultivars of Pothos, 6 Peace lilies, 2 Ficus, 2 Lady Palms and 1 Fan Palm.  These plants were ordered to replace some plants in the college interior scape. The plants we are replacing are covered the the dreadful  MEALY BUG! L

Yucca covered in mealy bug

 We started by cutting down the large Yucca to transport it easily back to the greenhouse where we can clean the pot and add in new plants! To avoid contaminating the other plants we used the tractor bay. 

 

  

 One of the plants was still recoverable but to get rid of mealy bugs you need to get every single one. Some even live in the soil!

Pedro had to bare-root a plant and cleaned it vigorously to get rid of the mealy bug!

This weekend was a lot of hard and it sure paid off! Here are the finished results!

Thanks for stopping by and checking out the blog! Catch you later!

Blog Entry Phyllis & Nicholas September 26-28, 2012

This weekend in the greenhouse was fairly hectic with the events of tree planting on Veterans Memorial on Saturday which left us a half day behind. Our top priority this weekend was to make sure that the poinsettia crop was in good order and watered/fertilized properly before drying out.  We also kept a close eye on the propagation chamber s misting cycle to ensure our crop for Landscape Congress are in good order.

Upon arrival each morning we immediately opened the shade curtains to end another night of black out period to ensure that the cycle was not interrupted. Even if it is only off by an hour you have to start your WHOLE blackout period over from the very beginning, if that happened at this point our crop would not be ready until January.  Once the blackout curtains have been pulled back we can start our routine opening checklist to ensure humidity and temperature is at a perfect state for our lovely poinsettias.  On Friday when Jack was here he showed Nicholas how to change the temperature setting on the Priva system because Jack felt raising the temperature by 2 would help the poinsettias grow.

The first task after that for me was to ensure that all poinsettias received the right amount of fertilizer at the proper concentration and water. The rule of thumb is to do one bench at a time and to be aware of light and darker cultivars. Starting off with the darker cultivars we readied the line with 250ppm fertilizer by placing the fertilizer irrigation line into the fertilizer bucket, turning off the main water valve and turning one the two lower fertilizer valves and letting the hose run until the water appears blue. Before we turned on the irrigation for the drip lines under the bench you would have to make sure that each row was turned parallel with the line but on half and half cultivar benches if the one cultivar was lighter you would turn the nozzle on those lines perpendicular to the line to ensure they did not receive the wrong concentration of fertilizer. Each poinsettia is required to be watered 400ml, we measured this by placing one of the drippers from a poinsettia on that bench into a measuring cup and keeping an eye on it until it reaches the proper amount the pouring from the cup into the un watered poinsettia.  After one bench was done I would begin watering the next and while watering that one I would rotate the previously watered poinsettias 180 degrees to even lighting and watering for the next time, and prune off dead foliage as needed.  We followed the same procedure for the lighter cultivars but with 300ppm concentration of fertilizer.

During the day on Friday we received a shipment of Cacti and Succulents from the Cuddy Farm location and were asked to arrange them on the bench separate as to ensure they were grouped by watering needs. While doing this Jeff asked us to re-pot any plastic potted plants into clay pots (adding crock (broken clay pots ) to the bottom for better drainage) to make them look more presentable.  We also brought back the three worst planters in Saffrons and replaced them with two lovely Ficus and one Oleander. On the way back from Saffrons we collected seeds from Quercus rubra ‘Fastigiata’ for Jack.

To prepare the Cannas from Clintar for winter we first cut back the foliage to just about 2” above the root. Then we lines bulb crates with old newspaper and filled it with moistened Promix HP. Next we placed the divisions into the soil as if planting, marked them and placed them in the tractor bay for now.

Among our eventful weekend we got to dig up, divide, and pot Pennisetum grasses for future use… we have been asked to prepare four flats of eight we sadly only got 2 and a half flats done due to time constraints. Along with the Pennisetum grass we also were asked to go around the campus to dig up the Colocasia plants and Black Magic Taros to also divide and pot up and prepare the bulb for overwintering (although there was not enough time to get instruction on how to do so, so we planted it for now)! Once all these plants have been potted and placed in a tray we applied 9g of Osmocote slow release fertilizer (15-9-12)and then placed them on the freshly installed heat mats ( thank you Nate & Bill) to promote optimal root growth.

Nic collected seeds from the Koelreuteria paniculata for stratification. He had to collect them from the ground seeing as there were no more pods left but he still got a decent amount. While trying to stratify them a few got destroyed but the majority worked out. They were placed in moistened soil in a baggie, marked and placed in the refrigerator   to mimic the winter process because this seed will not germinate until it has gone through a winter cycle.
