We are going to start our 2021 diary with a little experimentation. We haven’t grown watermelon for a number of years and have decided that we would like to try a couple of plants this year. After doing some research online we have decided we would like to learn to graft watermelon. Some of the benefits of watermelon grafting would be disease resistance and plant vigor. This will be totally new for us and we do not really know how it will turn out. We may have to grow traditionally if we can’t master the grafting process. Apparently, one of the most important things to have after grafting is to have some sort of healing chamber for the newly grafted plants to go into. This healing chamber needs to be kept at and a very high relative humidity at first and then slowly reduced over the course of a week. The grafts need to be in the dark for the first two days and then slowly introduced to light a little longer each day.
The picture below shows our newly built healing chamber (24” X 28” inside dimensions) with the control box on the right.

The control box contains a SHT2000 temperature and humidity controller. It is wired in such a way so that one half of the outlet supplies power to the humidifier and the other half delivers power to the heater. It is very easy to make changes to the settings to either raise or lower the heat/ humidity inside the box. The red display is the temperature and the blue is the humidity.

We started some seeds January 15 just for practice. We decide to use bushel gourd as the rootstock mainly because it was available to us. Unfortunately, we had very poor germination of the bushel gourds and we were only able to get 3 seedlings started from that batch. Today, we decided to try the first practice grafts. There are a number of different grafting techniques, but we decided for this first try to go with the one cotyledon graft.
This is one of the bushel gourd seedlings. They were not the healthiest looking plants but it’s all we had.

Here is the same plant after the true leaves as well as one of the cotyledons were cut off on an angle down the stem.

Next, is the watermelon scion that was cut on the same angle to hopefully match the cut on the bushel gourd.

Next a grafting clip was put on the stem

The seedlings were put inside the healing chamber and covered to keep light out. The humidifier is just a small bottle cap humidifier that fits inside a water bottle. The heater is a germination mat under the wire rack. The black probe on the top right is connected to the SHT 2000 controller. It measures both the temperature and the humidity.
Today we were privileged to witness history being made. Canada’s first pumpkin over 2000 lbs was officially weighed at the Woodbridge Fair. Congratulations to Jim and Kelsey Bryson for growing a 2006.5 lb pumpkin.
Here they are getting it off the pallet.
On to the scale
New Canadian record 2006.5 lbs.
Jim said it measured around 1850 lbs., so it went very heavy. It was grown from the 2014.6 Patton.
Our pumpkin surprised us by going heavier than it measured. Here they are getting it ready to lift with the Judge Chris Lyons close by.
The official weight was 1726.5 lbs. That was about 250 lbs. heavier than the measurement, so we were very happy with that. This is the second year now that the 2118 Barron has gone heavy for us. Would like to try this seed again next year.
Our watermelon even went heavy for us. It was measuring 135 lbs on the tape but weighed 160.5 lbs. It was good for first place, but it was the only watermelon entry.
Thank you to the Woodbridge Fair committee and volunteers for putting on the weigh-off.
We decided we would take our 2200 (est) Geddes to the Port Elgin weigh-off. Loading day last Friday turned out to be a very harrowing experience. The picture below shows our first lift out of the patch. As you can see the bottom rope is too high up on the pumpkin. I didn’t realize it at the time and continued to lift the pumpkin off the ground. A few seconds later the pumpkin slips out of the sling and falls to the ground. This caused the rope to rip off the stem. As well, two hairline cracks formed at the stem and blossom end. We probed the cracks and couldn’t get the probe to go very far into the pumpkin, but we didn’t know at that time what the bottom looked like. At this point we lost all confidence in our lifting device and did not want to attempt another lift.
I called Doug Court to see if I could borrow his pumpkin lifter. On one of Doug’s busiest days of the year, he stopped what he was doing, jumped in his car and drove the lifter down to us. I told him we could have gone to pick it up. Doug says “I had to come it was a pumpkin emergency”. Thank you so much Doug, you are a true friend. With Doug’s help we examined the bottom (it was good) and got it on a pallet. It was up to the judge now to determine if it was sound or not.
Weigh-off day…The pumpkin made it to the scale. The judge determined that it was good to be weighed. The weight was 1747.5 lbs. and placed forth.
Congratulations to Jim and Kelsey Bryson for their 1st place 1775.5 lb pumpkin.
This year’s weigh-off was a little bit more like normal. At least the growers were able to stay on site for the entire day if they wanted to.
It was good to talk with a lot of the growers that we missed last year. Below is Fred Hain and Dorothy in the background. Fred was showing us his nice orange pumpkin that he grew from our 1699 seed from last year. It weighed 1299.5 lbs !!!!
Congratulations to the Pumpkinfest committee and all the volunteers for putting this all together for us. It must have been very challenging at times.
Woodbridge is next.. Everyone... keep your ropes low.
Good luck!
Looks like we will be getting another batch of storms that are quickly coming across the lake. We are under a tornado watch. As a precaution we covered the pumpkins with blankets and had to lash them down with ropes to keep them in place. There is a risk that our shelters may be damaged in the windstorm and we wanted a bit of protection from the flailing structures.
Stay safe everyone!
The pumpkins are now heading into the home stretch. The storm last Tuesday caused a bit of damage to the plants from the hail and wind, but it could have been a lot worse. We now have a lot of holes in the leaves but overall the plants have recovered and the pumpkins are still growing.
We have been giving a lot of tours of our pumpkin patch again this year. Friends, neighbours and total strangers. Growing close to the road draws a lot of attention and you would think that could be a bad thing, but we have never had any problems over the years. Giving a tour and answering questions to someone who has never seen a big pumpkin before has to be my favorite part of this hobby. I’m not sure what it is about giant pumpkins that make people smile but it definitely does.
The 2118 Barron continues to grow at a decent pace. It averaged 17 lbs. per day this past week.
It is now sitting at 1384 lbs. It’s a wheel shape that is leaning.
The 2200 Geddes has slowed to 8 lb. gains per day this past week. It measures 423” OTT or 1630 lbs. That is now the largest OTT measurement we have ever had in out patch. The long range forecast looks good for day/night temperatures. We are hoping it will put on a few more lbs.
