Key Tips to Care for Your San Diego County Landscape in May
Landscape and Garden Tips for May
It’s May, and for your San Diego County landscape, this time of the year means that it’s time to prepare it for summertime. As days get longer and temperatures warm, you’ll want to irrigate deeply but less frequently. May is a great time to manage your water use, so if you’ve been considering upgrading irrigation controllers, consider Smart Irrigation Controllers that can adjust for warmer weather. It’s also wise to use a drip irrigation system to deliver water directly to the roots.

How to Care for Your Landscape in May
Irrigation: Check your irrigation system to prepare it for summer. You’ll want to ensure your landscape has adequate soil moisture. Irrigate thoroughly and apply enough water so that it wets the soil at least two feet deep. For loam soil, add about 3 inches of water. Deeply water fruit trees such as stone fruits, apples, and pears.
Mulch: Keep roots cool and reduce water usage by applying 3-4 inches of organic mulch to planting areas. For trees, ensure that mulch is at least a foot away from their trunks.
Deadheading: You can keep your landscape looking tidy and flower-filled by setting aside time each week to cut off spent blooms. Removing faded flowers from roses and other perennials will encourage new blooms.
Fertilizing: Add fertilizer to new, established plants, including camellias. Nitrogen fertilizer is ideal for warm-season crops.
Lawn Care: When it’s time to mow the grass, raise the mower blades to keep the grass blades higher. Higher grass blades protect against heat and can help retain moisture.
Wash: Your trees will benefit from a periodic wash. Give them a forceful spray of water, which can help remove dust, honeydew, and pests such as aphids, spider mites, and whiteflies.
Look for pests: Springtime means pests are out and about in your garden. Check for pests like the Diaprepes weevil on citrus trees. Aphids also like to cling to citrus and rose foliage —you can blast them off with a spray of water.

Weed Abatement in San Diego County
Keep weeds under control before they take over your garden. Staying ahead of weeds is essential, especially in wildfire-prone areas. You can always pull them by hand, but there are other valuable methods to control weeds.
- Spread pre-emergent herbicides
- Use post-emergent herbicides for visible weeds
- Inspect the landscape for weeds such as crabgrass, dandelions, purslane, and spotted spurge.
