Green Tips for the Month of June

Summer annual color including purslane, moss rose, firebush, copper plant, lantanas, gomphrenas, cleome, cosmos, celosia, purple fountain grass. Buy plants that have been acclimated to full sun in nursery.

Summer-flowering perennials from 6-inch and 1-gallon pots, including daylilies, coneflowers, gloriosa daisies, cannas and many others.

Aquatic plants alongside pools, watercourses and in containers.

Turf from sod, seed, and plugs or by hydromulching. Water once or twice daily for first week.

Crape myrtles in bloom to ensure exact shade desired, also other trees and shrubs. Transport home carefully. Plant immediately and water by hand several times weekly all summer.

Tomato seeds early in month for transplanting into garden late in June. Cuttings taken from spring plants can also be rooted.

Lower limbs that are weighted from new spring growth and causing excessive shading. All cuts should be flush with trunk or other limbs. Pruning sealant should be applied to oaks.

Tidy up spring growth of evergreens, but avoid formal shearing. Elaeagnus, Abelias and Lady Banksia roses are most prone to long, unwanted shoots.

Dried foliage from bulbs, wildflower plantings and seed stalks from spring-flowering perennials.

Flowers from coleus, caladiums, dusty miller, santolina, lamb's ear and basil. Flowers will stop further growth.

Blackberries, to remove all canes that have just borne fruit, completely to the ground. All of next year's berries will be produced on canes that grow this year.

Crape myrtles to remove spent flower heads and seeds and encourage additionalrounds of flowers over remainder of summer. Remove basal shoots that threaten tree-form habit.

Mow frequently (4-5 day intervals) and at recommended height to maintain dense, weed-free turf.

Lawn with high-nitrogen fertilizer. Water deeply after application to avoid burned grass.

Same high-nitrogen food to blooming landscape shrubs, flowers and vegetables to encourage continued growth and flowers.

Patio pots, hanging baskets with water-soluble, complete-and-balanced plant food with each watering. Use siphoning proportioned and water breaker for easiest feeding. Timed-release fertilizers are also good.

Blackberries after harvest and pruning, with high-nitrogen fertilizer for vigorous cane growth.

Treat iron deficiency (chlorosis) of wisterieas, azaleas, gardenias, hollies, hydrangeas and other acid-loving plants with iron additive also containing sulfur soil acidifier. Symptoms: yellowed leaves, dark green veins on newest growth.

Webworms strip foliage from pecans, walnuts, persimmons and others, forming
unsightly webs in the process. Remove while small with long-handled pole pruner. Spraying is difficult, inefficient.

Walnut caterpillars also strip foliage, but without the webs. Spray at first evidence with B.t. or general-purpose insecticide.

Grasshoppers, katydids with general-purpose garden insecticide. Spray downward motion. Keep tall grass and weeds trimmed.

Bagworms strip needles of junipers, cypress and other conifers. Treat at first evidence (early in month) with B.t. or general-purpose insecticide. Bagworms can quickly kill conifers.

Lace bugs turn leaves of pyracanthas, boxwood, azaleas, sycamores, Boston ivy and others manila-folder tan. Apply systemic insecticide.

Leafrollers cause leaves of trailing vinca, sweetgums, pyracanthas, redbuds and cannas to stick together. Control with systemic insecticide applied before damage becomes severe.

Spider mites cause tan mottling of lower leaves of tomatoes, violets, marigolds, junipers and beans, among many other plants. Apply labeled fungicide. Repeat as needed on 7 - to 10-day intervals.

Blossom-end rot causes tomatoes to develop dark brown, sunken spots where flowers were attached. It almost always is due to plants' getting too dry between waterings. It is not pathogenic.

Gray leaf spot causes yellowing of St. Augustine with visible gray lesions on blades, runners. Discontinue feeding until fall and treat with turf fungicide.

MSMA to bermuda turf to eliminate existing grassy weeds.

Second application of pre-emergent weedkiller granules by mid-month to prevent crabgrass, grass burs.
