What to plant in the September edible garden

Sunday, September 13, 2026

September is typically a great time to continue planting for fall and winter harvests.  Get the most out of your edible garden by using all the seasons for fresh, homegrown goodness.  With fall gardening, you don't have to worry about pest and disease pressures plus the temperatures are enjoyable for outdoor activity.  The one challenge is if you are still experiencing temperatures in the 90's.

A fall edible garden

This month plant more greens and root vegetables and transplant cold crops.  September is my favorite month for getting winter lettuce and greens going.  I keep pots just for year round greens.  The spring/summer greens have already bolted and gone to seed.  I cleared them out when the seeds are dispersed and the stalks turn brown.  I did have volunteer celery, lettuce, chard, and sweet mustard greens that has sprouted in some of them.  But we are letting the chickens free range and they scratched them all out.  LOL.  My Red Malabar spinach, New Zealand spinach and Giant Blue Feather lettuce is still going strong.  I started my lettuce, spinach, broccoli, chard and pac choi seeds earlier this week and most have sprouted.  I'll keep them in the shade and will transplant them when it cools off in self watering pots so that I can cover them with a portable greenhouse to keep the harvest going all fall and winter.

September is also a great month for starting perennial veggies, fruits, and herbs as well as flowers, trees, shrubs and spring blooming bulbs.  There are 2 great things about perennials.  1) You only have to plant them once and they come back year after year.  2)  Perennial greens are the first things up in late winter, early spring.  Keep in mind t hat new transplants do need extra moisture so either wait until the rains start or water a couple of times a week until they do and it cools down.   Midwest Perennial Vegetable Garden

The hardest part is finding a spot to start the cool season crops with so many summer veggies going strong.  I like to start them in smaller self-watering, rectangular pots that are about 6" tall by 12" or so long in the shade and then transplant them out when it gets cooler and more room is opened up.

Look for cold hardy varieties when planting for fall and winter harvests.  You will be surprised to harvest all through the winter months things like greens, onions, Austrian peas, carrots, and cabbage without any cover.  You can also extend the harvest by looking for the same crop with different days to harvest timing so that they mature at different times.  

Finally, you can use cover to extend the harvest all the way to next spring.

Winter edible garden

When planting seeds when temperatures can get hot, be sure to keep the soil moist and in a cool spot until the plants are well established.  Summer and fall planted crops take longer to come to harvest than they do in the spring.  Rule of thumb is to add 2 weeks.  It's because the days are getting shorter in fall rather than longer like in spring.  

A great and easy way to start your fall garden is to sow the seeds in a pot on a covered deck or patio.  This makes it easy to keep an eye on the seedlings and protects them from the harsh hot summer sun.  After they have a couple of sets of their true leaves, you can transplant into the garden bed.  Harden them off first by moving the pot to full sun before transplanting.  "Hardening off" seedlings  After transplanting into the garden, keep them watered regularly during hot, dry weather until well established.
