History of the summer squash plant
Summer squash was originally found in Central America. Ten thousand year-old summer squash seeds have been found in Mexican caves. Explorers such as Christopher Columbus brought squash back from North America and spread the vegetable around the world.
Growing summer squash plants
Summer squash plants need full sun and lots of air circulation to grow well. Crowding plants or planting in the wrong location can be detrimental to your squash crop.
Plant summer squash seeds 8 inches apart, poking them into the soil 1 inch deep; water well. Thin or transplant seedlings to 3 feet apart. (If using starts, set them out 3 feet apart). Summer squash seeds germinate in 7 to 10 days at 85°F (29°C) or warmer. Transplant summer squash starts into the garden after the soil has warmed to at least 70°F (21°C).
Summer squash plants have both male and female blossoms and they both need to be present for pollination to occur. Having multiple plants will increase the chance of pollination.
How Long does Summer squash Take to Grow
Summer squash grow quickly (in about 60 days) and are harvested throughout the summer while still young. Their skins are thin and tender making them edible unlike their cousins the winter squash varieties. However you should not let summer squash grow past the point of ripeness, the skin will become tough and bitter.
Pests and Disease
Be sure to check your summer squash plants for pests often. Squash bugs can set in pretty quickly, and are sometimes hard to spot. Also be wary of slugs, birds, small rodents and some beetles like summer squash plants too. You can tent your summer squash plants with netting, but I have found that this becomes more trouble than help.
You should also look for irregular white spots on on your summer squash plants, which could be mildew. Powdery mildew is a fungus that squash plants can be susceptible to. It can spread between plants. It begins by producing very characteristic powdery circular spots on the leaves. These spots grow larger and will eventually cover the whole leaf causing it to turn yellow. The fungus may also spread to other parts of the plants such as the stems, flowers or fruit.
The best way to prevent powdery mildew is to take the necessary precautions to prevent it. Make sure that you plant your squash in full sun and don't overcrowd them. This ensures maximum air circulation around the plant and allows plants to dry quicker when they get wet. If you do end up with powdery squash mildew my advice is to trim plants to increase air flow, and use an organic plant based fungicidal oil such as neem oil.
