July Gardening Checklist: Bugs, Day-Trips and More

Fellow Gardeners,

The information, dates and techniques in this blog are as accurate as I can currently offer. During the past three decades I have cared for, nurtured and observed tens of thousands of plants.

Beneficial Insects and Wildlife

Giant Whitefly enjoys the warm days and warm nights and infestations should be noticeable. Predators and parasites should also be present.

Check immature whiteflies carefully for signs of parasite activity. If none are found in one part of the garden remove a few leaves from another plant that has been parasitized and place it carefully into the foliage of the non-parasitized plant. Flea, grub and cutworm populations may be doing damage now. Control can be achieved by using various beneficial nematodes.

These microscopic worms are applied by mixing them in a water can and drenching the area, then watering well. Now that the weather has warmed, spider mites may be noticed on many plants, such as citrus, avocado, pine, juniper, ivy and others. Release beneficial predator mites now for control all summer. Encourage bats.

Fertilize

(See also the information under the individual plants)

Acidify. Now is a good time to add aluminum sulfate or soil sulfur to acidify you soils.

Pests & Diseases

(See also the information under the individual plants and Beneficial Insects)

Periodically rinsing off the foliage of the plants in your garden during the summer will significantly reduce many pest problems, especially mites and whitefly.

Places to Visit

Gardens that look terrific almost any time of the year include Sherman Library and Gardens (Corona del Mar),

The Fullerton Arboretum (Fullerton), Los Angeles Arboretum (Arcadia), Huntington Library and Botanical Gardens (San Marino) and Quail Botanical Gardens (Encinitas). The Orange County Fair offers horticultural exhibits, seminars and competitions from mid July through early August. Be sure to check out the Farm and Garden competition to see the award winning vegetables and fruits. This competition is open to everyone, requires no pre-registration and is repeated weekly for all three weeks of the fair.

Keeping Track

Records, Catalogs, Books and Organizations

• Summer is one of the best times to attend educational garden seminars and meetings. Many excellent programs are available and most, but not all, are free, require no memberships and no reservations. There is so much going on right now that you will have to pay close attention to keep track of it all.

• Make notes in your journal now, especially about water and pests. These will be useful to you again next year.

Soil Care

We have included this section, because as you know, or will discover with more experience, a good garden begins with the soil.

Investing in the soil, managing the soil and protecting the soil are not afterthoughts in a successful garden, but the foundation. Healthy soil is living and breathing, teaming with earthworms, microorganisms, beneficial fungi, bacteria, microbes and other invisible life. This section, possibly the most important topic of all will, provides some helpful guidance to good soil care.

A thick layer of organic mulch, averaging about two inches, should be maintained on top of the soil just about year-round. This is an excellent month to add additional mulch as needed to maintain this level. Applied now, a thick layer of mulch will cool the root systems from hot summer temperatures, reduce irrigations as much as half this summer, reduce weed growth, and improve both soil life and soil quality.

Soil Care (Cont.)

If you have been considering inoculating your soil with beneficial mycorrhizae, this is a perfect month in which to do it.

The soil temperatures are just right for quick establishment. Inoculation can be done very quickly and easily in established areas by using mycorrhizae “tablets”. In moist soil, poke a hole near the plant with a ½” or ¾” rod or stick. Drop a tablet into the hole and push it in again with the stick.

We do not suggest the use of very high analysis fertilizers in a garden, especially phosphorus. Examples of fertilizers to avoid are synthetic versions with formulations like, 10-55-10, 10-30-10, etc. We don’t even suggest the popular 15-30-15 formula.

Soil Care (Cont.)

These formulations will inhibit or even destroy much of the soil life that is so vital to a healthy sustainable soil.

We also suggest that you not use soil-applied systemic fertilizer/insecticide combinations (especially popular with roses). These are very damaging to soil life.

Use insecticides only when necessary and even then use the least damaging product available. Many of these products move into the soil and interfere with the invisible soil life.

Soil Care (Cont.)

If you can, begin a compost pile or purchase a compost bin.

Leaves, clippings, kitchen produce scraps, and many other ingredients can be composted and returned to the garden. Home compost is one of the very best ingredients you can add to your soil. The benefits are huge in the areas of disease suppression, increasing beneficial microorganisms, improving soil structure and texture, nutrient retention and nematode suppression.

Be sure that before you put a plant into the ground you have considered the soil and are doing all you can to improve it and protect its health.

Water & Irrigation

Water & Irrigation

(See also the information under the individual plants)

Periodically, rinse off the foliage of the plants in your garden during the summer. Larger shrubs, vines and trees will need a spray from a garden hose. This will cleanse the foliage of dust and some pollution. Pest problems will be reduced and the plants will “breathe” easier as well.
