Harvest. Harvest many vegetables when they are small and tender like beans, eggplants, squash, and cucumbers. Harvest corn, melons, garlic, onions, shallots, tomatoes beets and new potatoes (leave alone until fall for larger potatoes).
Fertilize roses. Roses are heavy feeders and usually require both a spring and summer feeding. Now is a good time as later feedings may encourage soft growth late in the season. E.B. Stone Organics Rose & Flower Food is a good choice.
Water. Keeping plants irrigated is a gardener’s most important task this month. Vulnerable container plants may need a daily soaking. Shallow-rooted plants like avocado and citrus need to be watered more frequently as well. Established shrubs, perennials, and shade trees will benefit from a slow, deep soak. In addition, mist plants with a hose occasionally to keep foliage clean and wash away pests like spider mites
Water citrus. Potted trees must be watered at least once a week, especially in summer heat, but mature citrus in the ground can go longer between waterings. Check soil moisture at the root level, 18 or more inches down, with a moisture meter, and keep soil on the dry side of moist (the soil surface doesn’t need to be damp). Water deeply and slowly when necessary
Divide bearded irises. Dig up old, overgrown clumps of bearded irises and divide rhizomes with a sharp knife. Discard woody centers. Trim leaves of remaining rhizomes to 6 inches. Replant divisions 1 to 2 feet apart.
Pinch and prune. Cut back spent hydrangeas but not too hard; leave at least three buds per stem for next year’s blooms. Cut back rangy annuals and perennials by at least one-third. Cut back fuchsias, and marguerites to encourage new blooms. Pinch back impatiens, pelargoniums and basil. Prune water sprouts, trunk suckers , and crossing or rubbing branches from trees.
Prepare beds. Before fall planting, amend soil with compost and soil co nd itioner, such as GreenAll Soil Booster. E.B. Stone Organics Super EarthWorm Castings are a terrific organic conditioner to loosen hard soils, improve soil aeration and conserve water.
Start fall crops. As you pull out early-summer crops, replace them with beets, broccoli, carrots, chard, collards, cabbage, cauliflower, kale, lettuce, radishes, spinach and turnips. Most will be ready to harvest in autumn. Starts and seeds of these vegetables and more are coming into the nursery now.
Replace annuals. Pull out faded spring and summer flowers and replace them with annuals that will look good well into autumn. We have a spectacular selection here at Evergreen and our friendly experts are happy to help you choose the best plants for your garden.
