Michigan Gardening To-Do List: July

Here’s a quick list of what needs to get done in your garden in July:

Herb/Vegetable Garden

  • 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.
  • At least once this month, feed your vegetable plants with a foliar feed of fish emulsion.
  • Start figuring out what you want to grow for your fall garden. Either start plants (such as broccoli, brussels sprouts, cabbage, kale, etc.) from seed now, or track down a good source of transplants.


  • Keep deadheading to keep plants looking their best.
  • Water regularly.
  • Fertilize once a week with a diluted (1/4 strength) solution of fish emulsion.
  • You can still sow seeds for many annuals, such as zinnias and marigolds, all through July for fall color as well.


  • Regular maintenance, such as staking and deadheading, will keep your perennials looking their best.
  • If you haven’t mulched your perennial beds already, this is a good time to do so. It will keep weeds down and reduce how much watering you’ll need to do.


  • If you’re growing tall plants, such as dahlias, stake them as needed.
  • If you still have foliage from spring bulbs (tulips, daffodils, etc.) in your garden, you can remove it once it turns brown.

Trees and Shrubs

  • Prune any spring-flowering shrubs this month.
  • Feed your shrubs with a granulated organic fertilizer, or topdress with some good compost.
  • Trees and shrubs will need an inch of water per week to stay healthy, either from rain or from the hose.
