Need Information About Planting Butternut Squash?
When planting butternut squash, it's best to sow the seeds where you want the plant to grow for the duration of the growing season. Squash plants won't tolerate having their roots disturbed. If you try and transplant seedlings, you're asking for trouble.
Butternut squash should be planted no earlier than 2 weeks after the last expected frost in your area. They can be planted up until 12 weeks or so before the first expected frost in the fall. It's possible to grow two butternut squash crops in a single year in warmer climates. The seeds germinate best when the soil temperatures are around 65 degrees F. Some folks with limited space wait to plant butternut squash after early spring crops such as lettuce and peas have finished. This is a good way to maximize garden space.
When planting butternut squash in a traditional vegetable garden, make sure the soil is well tilled down to a depth of 8 inches. Loose soil will give roots lots of room to develop and expansive root system. Nutrient rich soil will also help the plant grow large, which will allow it produce better quality squash. If you want to grow organic butternut squash, now is the time to add compost or well-rotted manure. Go ahead and till it into the soil when preparing your squash patch.
After the soil is well tilled, create hills or mounds of dirt about 12 inches across and 3-4 inches high. If you are planting bush varieties, space the mounds 3-4 feet apart. If you are planting vining varieties, allow 6 feet between mounds. Remember to choose a location that gets plenty of direct sunlight - at least 6-8 hours per day.
After the hills are constructed, use your finger or the end of a hoe or trowel to poke 2 holes in the top of each mound. The holes should be about 1 inch deep and a few inches apart. Drop a single seed into the bottom of each hole and cover it with loose soil. After you've finished planting butternut squash seeds, water them in thoroughly. When the seedlings reach 2 inches tall, thin to one plant per mound, keeping the best looking seedling. Thinning is necessary to make sure the plants have plenty of room to grow and aren't competing with each other for valuable water and nutrients.
If you want to plant butternut squash in containers, choose a compact variety. Look for the terms "bush", "compact" or "space saver" on the seed packet. You do not need to create hills if planting in a container. Choose a container that is at least 36 inches across and 18 inches deep. A good option is an old whiskey barrel that has been cut in half. Make sure there are adequate drainage holes in the bottom of the container. Be sure to use a nutrient rich potting soil or top soil. Don't forget to put the container in a spot that gets 6-8 hours of daily direct sunlight. Poke holes in the soil and drop the seeds in. Cover the seeds with soil and water them in well. Plant 2-3 seeds per container and thin to 1 plant per container when the seedlings reach 2-3 inches tall.
