Zone 9a specific growing notes
In zone 9a (Houston TX, Jacksonville FL), your 283-day growing season means beet should be one of your first spring plantings. Cool-season crops thrive in the mild part of your growing window. Monitor soil temperature â beet germinates best when soil is 40-75°F.
Your first fall frost around Dec 5 means your last possible harvest is roughly late Dec. For a continuous supply, consider succession planting every 2-3 weeks from Jan 28 through mid-season.
Pro tip for beet
Soak seeds overnight before sowingâeach 'seed' is actually a dried fruit containing 2-4 embryos. You must thin to one plant per cluster or roots will not develop. Eat the thinnings as baby greens.
Troubleshooting beet
Leaf miners create blister-like translucent trails inside beet leaves. Remove and destroy affected leaves immediately. Row cover at planting prevents the adult fly from accessing leaves to lay eggs.
Growing beet in containers
8-inch deep containers minimum. Standard round beet varieties work wellâa 5-gallon bucket grows 12-15 beets. Harvest greens continuously by cutting outer leaves; pull roots at 2-3 inch diameter for best flavor.
Can you plant beet twice a year?
Yesâsow spring crop 4 weeks before last frost, then a fall crop in late July to early August in zones 5+. Beets sweetened by light frost rival carrots. Mulch for overwintering in zones 6+.
