Lawn care

· Cold winter temperatures affected lawns but most survived and have begun growth.

· Delay feeding centipede and zoysia lawns until they begin new growth.

· Weed & feeds can be substituted for regular feedings.

· Know your weeds and the herbicides that provide control; make applications as needed.

· Fertilized but yellow lawns can often be regreened with an iron only application.

· Check the soil acidity of all home lawns; adjust the pH if needed.

· Mow zoysia lawns to the desired 2- to 3-inch height.

· Remove weeds, adjust the pH and till the ground before installing a new lawn.

· Starter fertilizers can be used with new lawns to supply phosphorus for root growth.

· Chinch bug controls are often needed at this time for St. Augustine lawns.

· Mole crickets are back in bahia, bermuda and zoysia lawns; control as needed.

· Spring is often dry; water when lawns begin to show moisture stress as permitted.

· Adjust sprinklers to avoid sidewalks and roadways and water only the turf.

· Apply up to three-quarters of an inch of water at each irrigation.

· Change the oil and service air filters of gas powered equipment.

· Sharpen mower blades when the cutting edges begin to dull.

· Edge lawns growing along sidewalks.

· Aerate lawns and remove thatch if needed.

· Don’t fight the shade; consider another ground cover for these problem spots.

Landscape chores

· Don’t waste plant growth; do needed pruning before new shoots form.

· Many plants normally affected by cold are still green; prune these to keep them in bounds.

· Prune the dead from declining plants several inches into healthy wood.

· Redirect the growth of out of bounds shoots and thin trees and shrubs as needed.

· Prune spring flowering trees and shrubs after the blossoms fade.

· Keep palms healthy; only remove the brown fronds plus fruiting stems as needed.

· Rake and use leaves as mulch or compost them for later use in the gardens.

· Keep weeds under control; control the young growths and apply a mulch.

· Plant a tree, shrub or vine on National Arbor Day April 30.

· Remove declining cool season annuals and add spring warm weather selections

· Make sure the root balls of all plant are moist at planting time.

· Build berms at the edge of root balls of new trees and shrubs to direct water to the roots.

· Give all poinsettias a spring trimming; repot new ones or add them to the landscape.

· Maintain 2- to 3-inch mulch layers with trees and shrubs; one inch in flower beds.

· Water annuals and perennials when the soil begins to dry or they show signs of wilting.

· Use slow release fertilizers that can feed landscape plants for months.

· Palms need special feedings; use fertilizers made for palms every 3 to 4 months.

· Inspect older trees and trim as needed before the hurricane season begins.

· Be safe; have arborist do the pruning of larger and older trees.

· Trim old flower stalks from amaryllis, amazon lilies and other spring flowering plants.

· Water new plantings as needed to keep the soil moist.

· Trim tropicals unaffected by cold as needed to keep them in bounds.

· Citrus greening has become a devastating problem; remove severely affected trees.

· Control citrus psyllids at each flush of growth; use sprays or soil treatments as instructed.

· Apply minor nutrient sprays to citrus trees at each flush of growth.

· Finish granular spring feedings of all fruit trees.

· Start sweet potatoes to have transplants for May.

· Pant tropical vegetables that won’t mind the summer heat and humidity.

· Complete herb plantings before hot weather arrives; many grow best in containers.
