This involves running your main vine out and keeping only the secondaries at a 90 degree angle to the main stem. Most growers choose the ‘Christmas tree’ style. Once the main vine is established, you will want to begin pruning your plants. Remove the cold frame when all possibilities of frost have gone. Some growers use small heaters or lights to provide heat during the cold nights, depending on your cold frame this may or may not be necessary. Water occasionally to keep moist, but not too wet. Remember to open your cold frames on warm days to avoid heat stress to the plants. Handle these plants with care when transplanting! A mild fertilizer can be added at the time of transplanting, but avoid over fertilizing early in the plants life. Plant the seedling in your cold frame with the fold of the first true leaf pointing away from the direction you want the plant to go. A day or two of acclimating to the outdoor temperature wouldn’t hurt the plants prior to actual planting. Once the seedlings are beginning to show the first true leaf (the two cotyledons appear first, the first true leaf will appear in the middle.) it’s time to transplant the plants outdoors in your cold frame. While you are waiting for the seeds to germinate, you should put small cold frames out in your garden where you intend to grow the plants. Seedling heat mats are the best source of heat for this process. These pumpkin seeds germinate best when the soil is kept at around 85 degrees.
Plant the seed pointed side down in your planting medium about 3/4”-1” deep. Soak the seeds for approximately 1 hour prior to planting. You should use an emery board to file the edges of the seed in improve germination. Start the seeds indoors in late April/early May in 4”-6” peat pots or other suitable container. Good tilth is also important, avoid compaction. A good amount of organic matter in the soil is beneficial and desirable. His favorite thing about growing giant pumpkins is seeing the smiles on people's faces when they see a giant pumpkin! Jim has paddled in the West Coast Giant Pumpkin Regatta 4 times and has had a pumpkin in every race since the event began in 2004. He is one of only 29 worldwide that have had that honor.
He was recently honored by being inducted into the Great Pumpkin Commonwealth Hall of Fame. His personal best weighed in at a whopping 1,868 pounds! Jim has been growing giant pumpkins for over 20 years. This helps decrease the risk of soil borne diseases.Jim Sherwood is a founding member of the Pacific Giant Vegetable Growers.
#Pumpkin seedlings skin
This can keep for 10 months or longer (provided the skin is unbroken).ĭon’t plant pumpkins in the same spot for up to two years – this includes other members of the cucurbit family (zucchini, cucumbers, melons and squash). Ensure plants are well-watered, especially in hot and dry conditions.Īfter harvesting, if you don’t plan on using your pumpkin straight away, let it sit in the sun for about a week and then store in a cool, dry and dark place. Poor fruit set can also be caused by heat and/or water stress, particularly when young. Do this early in the morning as the short-lived flowers can close by mid-morning. To hand pollinate, pick male flowers (sitting above a fairly thin erect stem), remove petals and gently brush over the centre of the female flowers (flowers sitting above a tiny swollen base). Hand pollination can be used to help improve fruit set. Bees help with this, so it’s important to encourage them to your garden by planting a variety of flowering plants, including salvias and lavender. Like most fruiting plants, pumpkins require pollination to help fruit set.
