Sow What Now in September

September has arrived. For a Northeastern garden, that means less than two months till our first frost, and shorter and colder days and an undeniable countdown to winter. One way to count down the slowing down of growth and daylight is to keep on sowing. Although it’s too late to plant most vegetable seeds, there are a few fearless edibles that march into the cold month with hardiness and flavor. Other varieties will put up with the cooling days if we just give them a little extra comfort – like a row cover jacket. And others still should be planted in autumn and will take the winter to acclimate, set root, and make their full-blown delicious debut as soon as the snow melts and the world is ready to grow again.

To know exactly when to plant, check the frost dates in your area (ours, in zone 6 is usually around mid October), then check the growing instructions on the seed pack, and count down from there. If the window of non-frost time is long enough, plant away with confidence! If the growing window is slightly shorter than desired, you can still plant and cross your fingers for a warm autumn, or expect to eat mini-vegetables. Do keep in mind that shorter days means less sunlight, which in turn means plants will mature slowly – add an extra 2 weeks to the “days to maturity” number to account for this.

Plant Now For Fall Plates*

053Radishes are one of the only roots that can still be sown in September. Plant them now for a few spicy farewell bites of fresh roots before welcoming the long storage root season.

Plant for Now or Later*

008Mache is a delicate and fragrant salad green that pays no attention to the cold. At the seed farm, mache came up in March, in the snow, before any other plants even thought about leafing out. Sow now for winter harvest and keep sowing through winter for cutting in the spring.

9Spinach, green of champions, and another cool weather fan. Sow it in early September for fall harvests, then sow again in late fall and keep under cover in winter for an early spring harvest.
