If your garden is already established there are a few things that you need to do this month to prepare your plants for the next growing season. If you are planting in a hot climate, pick a spot that will still have decent sunlight for most of the day. Not only do they like lots of sunlight, but they also prefer moist, well drained soil. For those established perennials, you will need to divide and replant those crowded plants which can expand your garden without the added cost. You should also test your soil, prepare the beds, and propagate anything you want to reproduce. This is a good time to weed, and apply high-phosphate fertilizer to soil where it is needed. This is also the best time to plant your spring bulbs. You can usually find a nice variety at your local supermarket. Wal-Mart carries a nice selection of bulbs, and the prices are not to bad either.
For warm to cooler temperatures, you should also divide your overgrown plants and planting new varieties. Plant your spring bulbs and weed, water, fertilize, deadhead or cut back blooms that are spent. If you are planting new plants now, try to plant them at least six weeks before the anticipated first freeze. If the soil is still warm the roots will go deeper. Inspect all plants for any pest or disease If your climate is a bit cooler, you should clean up your garden beds and add the debris to your compost bin. Mulch over the plant that have died back at this time.
If it is already very cold where you live, you can still divide your plants and plant your spring bulbs. Water them thoroughly and plant on a mild day if at all possible. You should try to get them in the ground before the first freeze. Any seedling that you may have started in the summer can be planted now. Pull out any remaining weeds and fertilize as necessary. Add all spent blooms and foliage to the compost bin. If you have already experienced your first freeze, then cut all plants stems back to the ground for the winter and cover them with a generous amount of mulch.
