Established Plants
Pruning
•As a rule of thumb, spring bloomers are pruned
after they bloom and summer bloomers are pruned in early spring.
Flowering Shrubs
•
Most shrubs, except conifers, should not be pruned until midsummer (late
June, July, and August) and after any flowering is complete.
• Remove spent flowers by cutting just above an active shoot or bud and below the flower head. Deeper cuts can be made if size control is needed.
Conifer Trees & Shrubs
•
Cut back new growth up to half of length as needles start to harden,
to control size and shape as desired.
Deciduous Trees
• Prune summer/fall to remove weak branches, parallel branches, intersecting
or rubbing braches.
• Remove any sucker growth from below the established branch line.
• If you desire to raise the branch line, do so gradually by removing the lowest branches after two years of growth.
Perennials
• Dead head perennials by removing spent flowers. Cut 1 to 2 leaf groupings
below flower
head.
• Fall cleanup - cut back dead foliage after hard freeze
• Some perennials have attractive seed structure and may be left until late fall.
Fertilizing
• Fertilize trees and shrubs regularly after the first year with any brand
of fertilizer recommended
for trees and shrubs. Apply 1 lb. / 100 square feet of bed area.
• Apply fertilizer in spring and fall before new growth appears.
