We’ve had success growing successive crops at the garden, most with very little trial and error. Yet, this was our first successful year with a second planting of zucchini and yellow squash. Now that we’ve done it, let’s document it.
We seeded our first crop indoors on May 16, planted the seedlings in the garden on May 31, and harvested 48 days after seeding on July 3. (That’s our normal schedule.) The second crop was seeded indoors on June 13, planted in the garden on July 5, and harvested 55 days after seeding on August 7.
Four weeks between seeding the crops seems right, and using a super-size 6-pack for the second crop was also helpful because the space for the seedlings wasn’t open for 3 weeks. It’s important to note that giving the seedlings their own space in the garden (rather than tucking them between the older plants) also made a big difference.
For the record:
In 2019, the second crop was seeded on June 22, planted on July 13 and did not produce a harvest, primarily because the seedlings were crowded and shaded.
In 2017, the second crop was seeded on July 9, planted on August 19 and did not produce a harvest, primarily because it was seeded too late.
