What's Your Email? On the westcoast we want our pumpkin plants started and in the garden by June 15th at the latest for a crop that can be harvested before October 31st! When we transplant our seedlings to the garden beds, I over plant the area with extra seeds directly into the soil in case any of the transplants fail.

As always, when gardening with kids, over planting is recommended. It is far easier to go back and thin the overgrowth then to try and fill in later in the season with purchased starts. Pumpkins enjoy a good compost heavy fertilizer.

Fertilization can be tricky for pumpkins if the vines are big and bushy. If you have an abundance of pollinator friends in your garden, re-arranging your flowers to make them more accessible is a good idea.

The pumpkin will grow from the female flower, which has a distinct bulb shape at the base of the flower. Pumpkins can be hand fertilized as well, which leads to an excellent lesson on pollination, cross pollination, and open pollination. Pumpkins prefer to be well watered, but do not like having water sprayed on their leaves.

Generously water the soil under the vines and add fertilizer weekly for large pumpkins. It can also be helpful to add grass clippings or straw to your garden beds to help regulate the soil temperature, keep the weeds down, and the soil moist. We like to transplant our pumpkin seedlings and then add some straw to the growing area to support the overall health of the plant.

Pumpkins are fairly drought tolerant once established, which makes them ideal school gardens crops to grow over the summer when kids are not in session and watering is less frequent.

Pumpkins are susceptible to powdery mildew. This is an airborne fungal disease that looks pretty awful, but generally does not affect the growth of the pumpkins late in the season.

Once the mildew has arrived, there is not much you can do. Harvest the pumpkins and dispose of the vines and leaves. The hardest part about harvesting pumpkins is knowing when to bring them in. In our school garden, we suffer the theft of our pumpkins regularly.

The garden is publicly accessed and, like most school gardens, we have to consider the timing of bringing our pumpkins in a bit early to protect them from theft, or leaving them on the vine a bit longer and having someone else harvest them. As general rule, harvesting pumpkins two weekends before Halloween reduces loss and theft.

Simply cut or snap the pumpkins from the vine to harvest. Interplanting: Plant pumpkins with bush beans, corn, dill, eggplant, lettuce, cucumbers, squash, and tomatoes.

Container Growing Pumpkins: Pumpkins are not a good choice for container growing. They require significant room to spread and grow. Pumpkins mature in 90 to days. Pumpkins are ready for harvest when skins lose their sheen.

The shells should be hard enough to resist denting by a thumbnail. Pumpkins are a member of the Cucurbitaceae family; other members are cucumbers, melons, watermelons, and pumpkins. More tips: How to Grow Pumpkins. How to Harvest and Store Summer Squash.
