Gardening Tips for July for Redwood City, CA

Southwest Region

  • The best time to do gardening chores is in the early morning or late in the day after supper; that way, you can avoid the heat of the day.
  • Finish pruning spring-flowering shrubs by midmonth.
  • Garlic and onions are ready when their tops start to bend over. Remove their tops after they've dried for a couple of weeks and store in a cool place.
  • Be alert for summer drought conditions. Be sure to water your flower beds and vegetable gardens deeply two to three times a week.
  • Mulching is an important job to keep up with in July. Organic mulches break down over time, so be sure to check the mulch around your plants. Keep a 3- to 4-inch layer of mulch around your plants to retain moisture. Also keep a thick layer of mulch around the roots of trees and shrubs.
  • During these warmer months, raise the mowing height to 2.5 to 3 inches. Water your lawn with 1 inch of water per week to ensure healthy growth.
  • Harvest vegetables and fruits regularly to keep your garden productive.
  • Plant transplants of tomatoes, eggplants, and peppers. You can also start seeding lima beans, pumpkins, and squash.
  • Late this month, plant iris and daylilies. Prepare soil now for fall planting.
  • Dig up and divide crowded spring-blooming bulbs whenever they are dormant.
  • Generally, trees and shrubs need deep watering with a hose every 10 to 14 days to a depth of 3 inches at the roots. Do not fertilize.
  • Stop fertilizing trees and shrubs so that they can start preparing for winter dormancy.
  • Remove any faded or dead flowers to encourage new growth.
  • Remove annual flowers that have finished flowering.
  • Feed your roses at midmonth to encourage more flowering.
  • Water your containers twice a day. Apply a slow-release fertilizer.
  • If white crust develops in containers, it's salt buildup; remove and water heavily to flush out salts.
