When to plant mustard greens in Alabama
Direct sow mustard greens around Mar 21 — the Alabama statewide median, counted from a last spring frost of Mar 21 across 656 ZIP codes and 126 NOAA stations.
The rule: Direct sow as soon as the soil can be worked in spring, and again in late summer for fall. Seed germinates fastest at 55–65 °F and may stall above 80 °F.

What Alabama mustard greens need
Organic Seed Starter Potting MixMust have
Seed-starting mix is not potting soil with a nicer label — it is finer, lighter, and low in nutrients on purpose, because a seedling's first roots want air and moisture, not fertiliser.
72-Cell Trays with 1020 Bottoms, 5-PackMust have
The cheap black nursery trays crack after one season and flex enough to break roots when you lift them. These do not. Over five seasons the price per use is lower than the throwaways.
AG-30 Frost Protection Row Cover
AG-30 buys roughly 6 °F of frost protection while passing about 70% of light — enough to carry a crop through an early-October cold snap that would otherwise end your season two weeks short.
Ultra-Fine Garden Netting, 10×33 ft, 2 pcs
A hornworm is a moth's decision made in June. Fine mesh over the bed at transplant means the moth never lands, and you never spray anything at all.
6" Micro-Tip Pruning SnipsMust have
Ninety percent of sauce-garden cutting is snipping a pepper stem or a basil node, and a fine-tipped snip does it better than any pruner. Pulling peppers by hand tears the branch.
Digital Kitchen Scale, 11 lb, g/ozMust have
Fermentation brine is a percentage of weight, not a number of spoons. Without a gram scale you are not following a fermentation recipe — you are guessing at the one number that determines whether it is safe.
One-Touch Coffee & Spice Grinder
Dried cayenne into powder in fifteen seconds. Dedicate one to chiles — grind coffee in it afterwards and you will find out exactly how well capsaicin sticks to plastic.
Half Pint (8 oz) Regular Mouth Mason Jars, 12Must have
Eight ounces is the right jar for a sauce you use by the spoonful. Open a quart of hot sauce and you are racing the fridge; open a half-pint and you finish it while it is still good.
