Planting: May is a good month to plant palm trees. Most trees can be planted now but will need to be watched in regards to watering.

Transplanting: Is best to be done in the fall or winter months.

Fertilizing: Fertilizers will still be beneficial if applied this month.

Pest Control: Watch your trees for anything unusual and bring a sample of the infected leaves to the nursery for diagnosis and solution to the problem.

Pruning: It is still ok to prune your trees.

Watering: As the weather turns hotter it will be necessary to water newly planted trees. Your trees require a rain of 1 to 1 ½ inches per week – if not then you must water them. You can water them with the hose on trickle for 30 to 45 minutes. Do this as needed until a good rain occurs.

Planting: You can continue to plant container grown roses.

Transplanting: Do not transplant roses at this time.

Fertilizing: You can fertilize again this month (six to eight weeks after your spring fertilizer application).

Pest Control: Continue to do preventative treatments for blackspot. Spider mites may occur if the weather is hot and dry. You can detect them by placing a piece of white paper under the branch and shake the branch. If you see tiny, moving black spots on the paper then you have spider mites.

Pruning: Other than deadheading and pruning off sucker from below the graft union, no pruning is required this month.

Watering: More water is needed as the weather heats up. Water thoroughly once or twice a week. Avoid wetting the foliage to help prevent disease.

Planting: Warm-season grasses may be done through September. Planting now gives the grass allows it to establish over the long summer months and better endure the cold of its first winter.

Fertilizing: If you didn’t last month do so this month.

Pest Control: This is the last month to apply broadleaf weedkillers before the weather becomes hot.

Mowing: Ideally, no more than the top third of the grass blades should be cut each time you mow.

Watering: Your lawn requires ½ to 1 inch of water per week. If we haven’t received that amount of rain, then irrigation becomes necessary.

Planting: Although the weather is warming up you can still plant container grown plants successfully. Just use a root stimulator and make sure the plant is watered adequately throughout the summer.

Transplanting: This is not a good time to transplant due to the increased heat.

Fertilizing: You may notice the leaves of your shrubs turning yellow. This is due to a deficiency of iron. By fertilizing with an iron rich fertilizer the plants will return to their healthy green color quickly.

Pest Control: Watch for signs of pest problems. If you need help identifying a problem give us a call.

Pruning: About the only shrubs you wouldn’t prune now are those that bloom in summer.

Watering: Shrubs absorb water faster from the soil as temperatures rise. Shrubs planted within the last six months may need to be watered once or twice a week whenever beds are dry.

Planting: You can plant perennials this time of year if you make sure to water deeply to protect them from the heat.

Transplanting: It is risky to dig and transplant or divide perennials this late in the year.

Fertilizing: Most of your fertilizer applications should be finished by now. If you haven’t fertilized yet do so now.

Pest Control: Most perennial plantings are not constantly plagued by pests.

Pruning: Continue to deadhead.

Watering: Soaker hoses are an effective way to water perennial beds without getting water on the flowers and foliage.

Planting: You can continue to add summer bulbs to the landscape.

Care: As flowers fade, trim them off to keep the plant looking neat.

Watering: As the weather gets hotter, bulbs will usually require more frequent watering if there is not enough rain.

Fertilizing: Fertilize bulbs growing in containers with your favorite soluble fertilizer.

Pest Control: Watch for aphids, caterpillars, and leaf miners – treat accordingly.


Planting: Plant warm weather annuals and water-in with root stimulator to get the young plants off to a good start.

Fertilizing: You can fertilize annuals with a slow-release fertilizer or a soluble fertilizer.
Pest Control: Watch for sucking pests such as spider mites lace bugs, leaf hoppers and plant bugs.
Watering: Newly planted flower beds will need thorough watering if the weather is dry.
