Gardening Tips

Monday, August 31, 2020


  • Do not apply any more nitrogen to lawns; it is time for them to get ready for winter.

  • Days are getting shorter and cooler. Start cutting back on irrigation this month.

  • If your soil test report showed low potassium levels, apply a high potassium fertilizer such as 0-0-50 (2 lbs. per 1,000 sq. ft.) by mid-September.


Trees, Shrubs and Flowers

  • September is a good time to divide and transplant spring-blooming perennials.

  • Plant pansies and other winter annuals from mid-September through mid-October to get established before frost.

  • Resist the urge to do any major pruning in the fall. Fall pruning depletes food reserves needed to initiate spring growth. Only prune out dead, dying or diseased branches.

  • Kept last year’s poinsettia? You can get it to flower by placing it in total uninterrupted darkness for 15 hours a day, starting the last week of September and continuing until colored bracts appear. Give them plenty of sunlight during the day.



Fruit, Vegetables and Herbs

  • Set out broccoli, cauliflower, cilantro, dill, kale, cabbage, Chinese cabbage, collard, lettuce, spinach, and Swiss chard transplants in early September.

  • Watch out for caterpillars and aphids on fall vegetable crops.

  • Muscadine grapes start ripening now and continue through the fall.

  • Fall is a good time for improving your garden soil. Add manure, compost, and leaves to increase organic matter content.
