Summer is finally here and it’s time to take care of our blooming landscapes. This is a busy season for most of us, but getting outside can be relaxing and rewarding. Use this helpful checklist to have a colorful landscape this year.
Vegetables and Fruits
Fertilize strawberries and water regularly to promote new growth Plant another crop of sweet corn, green beans, squash, and cucumbers Watch tomatoes for foliar leaf disease development and treat Watch out for squash bugs and control at first signs of infestation Mulch crops for moisture conservation and weed control Continue a regular fruit disease and insect control program Treat peach trees for trunk borers Remove sucker growth from base of trees and along branches Pinch herbs to keep bushy and fresh with new growth Turn compost pile and keep moist for a quicker breakdown
Flowers
Pinch chrysanthemums for development of a bushy plant Remove flower stalks from peonies and iris Mulch flower gardens for the summer to conserve moisture, control weeds, and cool the soil Deadhead spent flower blossoms to keep plants flowering Water plants with about one inch of water per week as needed Fertilize roses with about 1 cup of low analysis fertilizer per plant Check plants for insects Remove dead foliage from spring bulbs Water and fertilize container plantings regularly to encourage growth and flowering
Lawns
Raise mowing height on bluegrass and tall fescue to 3” or 3 ½” for summer heat resistance Let grass clippings fall for nutrient recycling Fertilize buffalograss lawns if desired Water the turf sparingly to increase drought tolerance during heat of summer. Let turf wilt between watering for best results Check mower blade for sharpness and sharpen as needed Check lawn mower engine oil and add or change according to owners’ manual
Trees and Shrubs
Check for bagworms and control as needed Mulch around the bases of trees and shrubs to conserve moisture Prune pines and spruces to shape and control size Water newly planted trees and shrubs as needed Prune spring flowering shrubs Do not damage tree trunks with mowers and weed whips Check for spider mite damage on various shrubs Clip hedges as needed to maintain shape
Houseplants
Fertilize throughout the summer months to encourage growth Wash leaves to remove dust Take cuttings to start new plants Prune and shape plants for added beauty Repot plants as needed in 1” larger containers Check for insect problems K-State Research and Extension has a variety of resources for all your gardening and landscaping needs this summer.
