2. September Planting
Here are the planting tasks that I typically focus on this month. Don’t forget I’m gardening in USDA hardiness zone 6b – you may need to make adjustments for your climate.
Sowing Seeds Outside in September
- Radish (I like this Easter Egg Blend from Botanical Interests)
- If you have clay soil, consider growing daikon radish as an edible cover crop that will loosen your soil over winter.
Getting Ready for October Planting
- October is the time to plant garlic (Chesnok Red hardneck variety is one of my favorites), fruit trees, berry bushes, and rhubarb, so order them now!
3. September Garden Maintenance
There’s lots of maintenance to do in the garden over the next few months. Start in September so you’re not overwhelmed this winter!
- Cut spent herbs and flowers or leave seed heads to feed the birds through the winter.
- Watch out for beneficial insects such as ladybug/lacewing larvae, and garden spiders.
- Do you have large black and yellow garden spiders? Here’s more about these beneficial insects.
- Remove diseased plant matter and dispose in garbage.
- Cut back herbs and use them as fertilizer.
Many varieties of brambles (i.e., red raspberry, blackberry, black raspberry) require a fall pruning. Here’s how I prune my black raspberries.
Be sure to store your seeds properly.
