Soil & site
A rich, composted mound. Zucchini are hungry and fast.
Seedling care
Direct sow 2 seeds per spot and thin to the strongest.
Growing notes
Squash vine borer is the Southern menace — a second sowing 4 weeks later outruns them. Sawdust-like frass at the stem base is the tell.
Harvest
At 6–8 in, checking daily. They genuinely double overnight.
