September in the garden
- Plant perennials. Now is the best time. With the cooler weather they will begin to be established and give you a head start into next year.
- Leave the seed heads of spent flowers on the plant (at least some of them). They are good for wildlife and will offer you seeds to harvest if you want to start plants from seeds next year. By mid September stop cutting roses and let them go to hips. This is a signal to the plant to go into dormancy for the winter.
- Plant onions and garlic for harvesting next spring (onions) and garlic (summer). Use transplants you can get from some nurseries or by mail order. You can also plant by seed some lettuces, radishes, spinach, arugula, etc for fall crops. Collard transplants can be planted.
- Order your bulbs or get from local nurseries. They shouldn't be planted til mid October through December. Plant in sunny areas. Plant 3x as deep as the diameter of the bulb. You can also layer the bulbs by planting the latest blooming at the bottom of a big hole. Add soil, then plant the early bulbs (crocus, snowdrops, etc.). They will bloom in succession. Daffodils are the best bet because they are poisonous to squirrels and other wildlife and also because they will naturalize. These animals know they are poisonous and don't dig them up or eat them. 'Tet a tet' is a great dwarf daffodil as is 'Jack Snipes' if you have small spaces. I like to order from Brent and Becky's Bulbs.
- Wait to prune until the shrubs and trees go dormant in the winter or early spring.
- Review your garden for the past season and make notes of what worked well, what you want to move or replace. Make notes.
