If you need an former start , plant indoors in 2 to 3 - inch pots or electric cell for three to four weeks before transfer them outside .
Before transplant , acclimatize plant by easy bring in them to external temperature and subdue water applications . After all scourge of Robert Lee Frost has passed , industrial plant transplants in the garden at the final spacing mentioned .
Caring for Winter Squash
Butternut squash is a intemperate feeder ; you will ask to sum some nitrogen to boost your craw yield . Once your plant has attain a reasonable size , block fertilizing to trigger heyday formation . you could boost nutrition once the pods have take shape , but avoid overdo it .
Irrigate the squash plant on the base , as wetting the foliage benefits disease - carry bacteria . A thorough souse come after by an opportunity for the origin to dry out out and get some air is the best approaching for all plants .

Mulching industrial plant aid in moisture retention and weed ascendency . Squash borers wo n’t wedge eggs if you pile soil up around the base of the plants .
How to Grow Summer Squash

Frequently Asked Questions
Why are my squash flowers not forming fruit?
Squash ( both summer and winter ) is a monoecious works , take form separate male and distaff flowers on the same plant . Ambient temperatures are known to affect gender expression in cucurbits . nerveless conditions , specially on nights , favor female flower formation , so they emerge first .

Typically , female flowers appear a hebdomad or two before male heyday . stumble seed planting by ten days to ensure both genders are available simultaneously for optimal pollination .
When should I harvest my squash?
reap the squash rackets when each fruit is large enough to eat , and do n’t grant them to get large and old . If you harvest regularly , the plant will produce raw bloom and retain to grow immature squash . yield production is motivated by posterity , so allowing all the fruit to mature before harvest stops yield initiation . If the yield is perpetually removed from the plant , production will remain .
Why are some of my squash’s ends rotting? What can I do to prevent this from happening?
Blossom end rot is rough-cut in early - forming squash racquets , tomato , or white pepper plants . The fruits that postdate should be hunky-dory .
