June Delaware Garden Guide

<<May Garden Guide

For the First Week of June:

  • Check your bedding plants; remove old flower heads to prolong the blooming period.  Also, pinch mums for bushier plants.
  • Make another planting of vegetables, such as sweet corn and snap beans.
  • Thin out vegetable plantings, for instance, beets and lettuce.
  • Feed your roses every month until early August with 1/4 cup of 10-10-10 per plant.
  • A second pruning of new growth on your evergreens may be made to maintain shape and size.
  • Continue your fruit tree sprays as scheduled.
  • Do not allow children to ride or drive riding lawn mowers.  These mowers are much more dangerous than they appear.  Always disengage the mower blades and set the brake before getting off for any reason.

For the Second Week of June:

  • Prune spring flowering shrubs after blooming is finished.
  • Spray your mimosa and honey locust for web worms.  Look for small clumps of leaves tied together with silk threads scattered over the tree.  Upon closer examination, the upper surface of the leaves are skeletonized.  The leaves turn brown and die, which will make the tree look as if it has been scorched by a fire.
  • Take care of your newly planted trees and shrubs.  They should receive a thorough soaking each week.  Mulch to conserve moisture.

For the Third Week of June:

  • Control aphids and other pests on vegetables by removing, spraying or washing.
  • Place cages or stakes to support growing tomato plants.  Cages or trellises work well for growing cucumbers, too.
  • Be careful trimming grass around young trees and shrubs when using weed eaters.  The young tender bark on these plants can be easily broken, resulting in injury to the water-transporting tissue and creating openings for insects and  disease to enter.

For the Last Week of June:

  • Continue spraying your roses and fruit trees.
  • Thin out flowers where they are growing too close.
  • Check your ornamentals for scale insects; these need to be treated if present.
  • The ideal time to harvest herbs is just before flowering.  This is when their leaves contain the maximum essential oils.  Cut your herbs early on a sunny day.
  • During the hot summer months, mulch can be especially useful for conserving water.  Dried grass clippings are an excellent mulch material.
  • Mid to late June is a great time to start new plants from soft wood cuttings of shrubs, such as azalea, spirea, boxwood, camellia, hydrangea, etc.

Mow and fertilize strawberries after fruiting.
Happy gardening!
