Garden care
- Set up deep watering4 sowings: Jul 3 and Jul 17 and Jul 24 and Jul 31
Switch to fewer, longer soaks (1-1.5 in/week at the root) instead of daily sprinkles. Sowing again a few weeks later keeps the harvest coming instead of arriving all at once.
Sow cover crop
- Cover crop (cereal rye + crimson clover)around Jul 21
Sown a month before frost it germinates, holds your soil all winter, and feeds it in spring.
