What to do in the Garden - July

July is a busy month in the garden to nurture new plantings and keep an eye on the established ones. Summer crops should be watered consistently and fertilized for the warmer months ahead. Meanwhile, keep an eye on weeds, pests and disease. Investing time this month will help mitigate problems later in the season.

Check your irrigation system for leaks, and make any seasonal adjustments.

Planting schedules are general guidelines and will depend on your particular microclimate and current weather patterns.

 

Food Gardening

  • Regularly harvest vegetables such as pole beans, cucumbers, and summer squash, which prolongs the harvest season.
  • To encourage leaf growth in basil, prune basil to the first leaf bud below the flower to encourage further leaf production. Harvest mature leaves frequently to prolong the harvest.
  • Central Coast gardeners succession plant leaf lettuces, greens, radishes and carrots nearly year-round if you're in an area that is relatively cool in the summer, or if you have a cooler spot in the garden. Succession planting means planting additional sets of these veggies every few weeks or once per month, for harvesting throughout the season.
  • Some warm season veggies and herbs like summer squash, beans and basil can be succession planted this month. Research the varieties before planting, noting those that require fewer days to maturity and are disease resistant, for best results.
  • Check for pests and diseases regularly before they become a bigger problem.
  • Garlic bulbs are harvested when most of the stem turns yellow and brown, depending upon the weather: heat will speed them up and cold will slow them down. Both garlic and onions need to be cured before being stored. They may be dug and left in the garden to dry.

Fruit Trees

 

If you haven’t already, thin the fruit on your trees for a better harvest. Read about fruit thinning here. 

 

Miscellaneous 

  • Although we recommend mulching for garden beds and paths, many native bees build nests in bare soil. Keep a few places open with bare soil to host these important pollinators.
  • For planted areas, or preparing fallow beds, suppress weeds while amending your soil by adding compost and mulch to help retain moisture, and/or sheet mulch. Keep mulch at least 6" away from tree trunks and plant stems.
  • Irrigation systems: Run it to check for leaks. Make repairs and seasonal adjustments.
  • We encourage Integrated Pest Management, ongoing strategies to manage pest damage. Direct, regular observation is a good practice. For example, carefully check kale, cabbages and broccoli for aphids or caterpillar activity. Take a flashlight tour of your garden at night to catch slugs, snails and other critters you might not see otherwise! 

 

Evergreen Tips

  • Sterilize planting containers if you are reusing them. Wash with mild soap and water to clean. Disinfect planting containers with a 10% bleach solution, meaning 1 part bleach to 9 parts water.
  • Sterilize your pruning tools regularly to not spread disease.
  • Remove diseased plant material (or discard in your green waste can) to keep your garden as disease free as possible. Do not add diseased plant material to your home compost or leave them in your garden beds. Some pests and diseases can overwinter.
