Texas spans more than one climate: Zone 8 is the most common zone, but the state runs 7a to 10a. That's why the planner works from your ZIP code's frost dates, not your zone: mountain and coastal gardens in the same state can be three weeks apart.
In Texas: watch for
The pests that find zucchini here.
With about 255 frost-free days, squash, summer spends longer in the ground here than in most of the country, which widens the window in which squash bugs can find it. Scout weekly from midseason and act on the first signs.
Gray shield bugs; leaves wilt and get crispy patches.
Organic fix: Lay a board out overnight and collect them at dawn; scrape bronze egg clusters off leaf undersides.
Sudden wilt with sawdust-like frass at the stem base.
Organic fix: Cover young plants; slit the stem to remove the grub, or inject Bt.
Yellow striped or spotted beetles chewing leaves and blossoms.
Organic fix: Row cover until the first female flowers open, then hand-pick.
White powder coating the leaves late in the season.
Organic fix: Space for airflow, water the soil rather than the leaves, use resistant varieties.
Your season math: Texas gives zucchini about 255 frost-free days, and it needs roughly 50 days to a first harvest. That fits about 7 re-sown rounds across the season, so you can keep it coming instead of picking once.
