The Herbarium
Grow lab · East Tennessee hill country
USDA 6b
Sep
Last spring frost mid-April. First fall frost mid-October. A ridge runs colder than a hollow. Treat dates as a week either way, not a promise.
Sow
Spinach, radish, lettuce — the fall bed
September is the second spring. Sow thick, thin for salad.
Spinach
Set out
Set the July brassica starts
Onion ring, alyssum skirt, nasturtium trap — same guild as April, cooler air.
Cabbage · Kale · Broccoli · Sweet alyssum · Nasturtium
Harvest
Tomato, pepper, dry bean, potato, cut flowers
A first light frost can still be two to four weeks out. Do not wait for it on a ripe fruit.
Tomato · Potato · Zinnia · Dahlia
Plan
Order garlic and divide peony if the clump is crowded
Peony hates a move. If you must, this is the month — eyes shallow.
Garlic · Garden peony
