If you’re a gardener, you can sense it: the end of seeding is nigh. Most of my seed trays and seed starting equipment have already been washed, sterilized, and packed away. September isn’t the end of the gardening season, though. There’s still plenty to sow and grow outdoors. This year, I’m excited to celebrate the change of seasons by starting a new indoor seed tradition: hydroponics. Here’s what I’m sowing this month.

Although it sounds counterintuitive, there are hardy annuals such as cornflowers, annual poppies and larkspur that will benefit from being sown now. These particular flowers will cold stratify over the winter for particularly profuse flowering next year. The same goes for perennials such as larkspur, amphibian and nigella. Remember, these will not germinate this year, but will next year, so sow them again.

You should still have time now to direct sow your basic succession crops outdoors: lettuce, radishes, spring onions and beets. Depending on your zone and climate, you may even be able to do another round of sowing in a few weeks. If you feel confident, you could try direct sowing winter brassicas such as broccoli, cabbage and cauliflower, although at this point you would be safer planting vegetable plants instead.

What you will need to put down a lot of are both carrots and onions. Choose a few types of carrots: both short carrots that are ready in sixty days and storage carrots that can be left in the ground over the winter. Carrots happen to benefit greatly from this overwintering. Onions take a long time to grow, so you can also find onion plants that you can plant now, but you should also try growing them from seed.
