*Plant late-season vegetables such as peas, broccoli, cauliflower, cabbages, kale, Brussel sprouts, leeks, lettuce, radishes, turnips, and onions. – If you love to grow salad all year round, then now is the time to sow some winter salads. Rocket, winter lettuces, and spinach can all grow throughout the winter. Once they’re sown, put them in a large pot, sheltered place, or greenhouse.
*Weeding galore… September is not different to most other months when it comes to weeding! Try to do small amounts well and often, to avoid the weeds really taking hold.
*Late summer/early autumn is a good time to collect seeds you want to use next year. Collect from seed heads, carefully shaking or scraping out the small seeds and store in dry place - a sealed tin is useful.
*Start the autumn cleanup. Remove any old crops that have finished and clear away weeds to leave your plot clean and tidy for the winter.
*When beans and peas finish cropping simply cut the plant away at ground level, leaving the roots in the soil. These crops fix nitrogen which is slowly released into the soil as the roots break down.
*Pot up mint and parsley for the kitchen windowsill, to use through the winter.
*Now is the best time to improve the soil before it becomes too wet or frozen. Incorporate organic matter and agricultural lime. Sow green manures such as mustard, clover, winter wheat and rye grass on uncultivated areas to improve soil and keep weeds down over winter. These “green manures” can be plowed under in the spring for a natural fertilizer and soil conditioner. A thank you to gardener, Ira Hammack, who is getting the gardeners a large bag of winter wheat. See me if you want to get a sack full to sow in your garden plot.
*Make rough sketches of your vegetable plot to help plan for next year. Reflect on what worked and what didn’t!
*Cure winter squash for storage. Place in a cool, sheltered shady spot for about 1 month.
*Once asparagus foliage has turned yellow, it is no longer feeding the plant, so cut it down to just above the ground to make way for spring growth and to discourage the overwintering of asparagus beetle.
*Prepare Brussels sprouts for tougher days ahead by mounding up around their stems and firming down around their bases. They are not the most logically shaped plants for blustery weather, so repeat this periodically to prevent them from falling over.
*Watch for frost warning and cover tender plants.
