Summer Care Guide for Your Trees, Shrubs, Ornamentals, and Lawn in Southern California

How to Care for Your Landscape in the Summer Heat in Long Beach, Los Angeles, Beverly Hills, Palos Verdes, and Orange County

Summer in Southern California can be hard on landscapes. High heat, intense sunlight, dry winds, and inconsistent watering can quickly stress trees, shrubs, ornamentals, and lawn areas if they are not properly maintained. A smart summer care plan helps protect plant health, reduce stress, and keep your property looking its best through the hottest months.

Why summer care matters

During summer, plants lose water faster and have to work harder to stay healthy. Trees and shrubs may show signs of stress through leaf scorch, wilting, thinning canopies, or early leaf drop, while lawns can brown, dry out, or become patchy. Ornamentals may also suffer from pest pressure and fungal issues when they are already weakened by heat.

Tree care in summer

Trees need deep, consistent watering during hot weather, especially newly planted or drought-stressed trees. Water should reach the root zone slowly rather than running off at the surface. Mulch can help conserve moisture and regulate soil temperature, but it should be kept away from the trunk to avoid problems.

Summer is also a good time to watch for signs of stress such as wilting, browning leaves, dead twigs, or sparse canopy growth. In Southern California, trees near pavement, walls, or recently renovated landscapes are often under extra stress from reflected heat and root disturbance. If a tree looks like it is declining, a consulting arborist can help determine whether the problem is related to water, soil, pests, disease, or construction impacts.

Shrub and ornamental care

Shrubs and ornamentals benefit from proper watering, light pruning, and regular monitoring for pests and disease. In summer, stressed plants are more likely to develop powdery mildew, aphids, scale, spider mites, and sooty mold. Keeping plants healthy with the right irrigation and spacing can reduce many of these issues.

Avoid heavy pruning during extreme heat unless it is needed for plant health or safety. Over-pruning can expose shrubs to sunburn and additional stress. It is usually better to remove dead or damaged growth and let the plant maintain as much protective canopy as possible.

Lawn care in summer

Lawns in Southern California often need special attention during summer heat. Watering deeply and less frequently is generally better than frequent shallow watering, since it helps roots grow deeper and makes turf more resilient. Mowing at the proper height also helps protect the lawn from heat stress and moisture loss.

Brown patches, thin areas, and uneven color can be caused by drought stress, compacted soil, pests, fungal disease, or irrigation problems. Before making major changes, it helps to check whether the lawn is getting even coverage from sprinklers and whether the soil is compacted or hydrophobic.

Common summer problems

Summer landscapes in Long Beach, Los Angeles, and Orange County often face a combination of issues rather than just one. Heat stress, inconsistent irrigation, soil compaction, pest outbreaks, and poor drainage can all happen at the same time. That is why a professional evaluation is often the best way to identify the real cause of decline.

When to call a consulting arborist

If trees, shrubs, ornamentals, or lawn areas are showing stress that does not improve with normal care, it may be time for a closer look. A consulting arborist can evaluate the landscape, identify contributing problems, and recommend practical next steps. For Southern California property owners, early diagnosis can help prevent minor summer stress from turning into long-term damage.
