Here’s a quick list of what needs to get done in your garden in September:
- Keep watering and weeding.
- Harvest regularly to keep plants producing well.
- Deadhead herbs such as basil regularly to keep them productive.
- Check plants regularly for signs of pest or diseases.
- Remove any summer veggie plants that are looking ragged or becoming less productive.
- At least once this month, feed your vegetable plants with a foliar feed of fish emulsion.
- Sow more fall crops directly into your garden, including mesclun, spinach, mache, radishes, and carrots.
- Keep deadheading to keep plants looking their best.
- Water regularly.
- Fertilize once a week with a diluted (1/4 strength) solution of fish emulsion.
- Remove summer annuals that may be looking ragged and replace with fall flowers, such as mums, asters, ornamental kale, or pansies.
- September is a great time to dig and divide any perennials that look overgrown to you.
- You can usually get good deals on many plants this month, when garden centers and nurseries start running their “fall planting” sales.
- You can start planting spring-blooming bulbs, such as tulips, daffodils, hyacinths, muscari, and snowdrops.
- If squirrels or other wildlife dig up your bulbs, place a section of chicken wire or metal hardware cloth over the area. Pin it down and cover it with mulch. This should protect it from those pesky critters.
Trees and Shrubs
- Trees and shrubs will need an inch of water per week to stay healthy, either from rain or from the hose.
