What to Fertilize:
--Don't be an April Fool!-Fertilize all early spring flowering plants (like
forsythia) and evergreens like holly, juniper and camellia in early April.
Deciduous plants like viburnum and dogwood also benefit from feeding this month.
--The garden literature says to fertilize azaleas and rhododendrons after their
flowers fade. To make life simpler, we suggest you feed your azaleas and
rhododendron in early April when you are fertilizing your other landscape
plants.
--Fertilize blackberries, grapes, blueberries and raspberries.
--Once you can determine whether your fruit trees have any fruit, you can decide
how much fertilizer to give them.
What to Plant:
--Set out flowering perennials like purple coneflower, rubeckia, etc. when
plants are available at local garden centers.
--Annual flowers can be planted outside in late April after the danger of frost
is past. Some commonly planted annuals are begonia, geranium, marigold, petunia,
salvia and zinnia.
--Plant gladiola corms this month and continue through mid-June.
--Many gardeners prefer to transplant azaleas in April so they can group the
plants according to their flower color.
--The following vegetables can be planted this month: beans, beets, cantaloupe,
corn, Chinese cabbage, cucumbers, pumpkin, squash, Swiss chard and watermelon.
What to Prune:
--Prune spring flowering shrubs like azalea, lilac and weigela after the
flowers fade.
--Prune berry producing shrubs like holly and pyracantha while they are
flowering so you won't remove all of next winter's berries.(Berries normally
form on 1 year old wood-often annual trimming removes the growth that is most
likely to have berries.)
--If needed, prune spring flowering trees like Bradford pear, flowering cherry
and redbud.
--Prune out any winter damage that may have appeared this year.
Pest Outlook:
--Check the following landscape plants for these insects and spray if needed:
azalea-lace bug, boxwood-leaf miner, camellia-tea scale, euonymous-scale, and
hemlock and juniper-spider mites.
--Spray hybrid rhododendron for borers.
--Spray iris beds for borers if problems have existed in the past.
--Spray red-tip photinia weekly with a recommended fungicide if leaf spot has
been a problem.
--Protect broccoli, cabbage and cauliflower from worms with an organic product
known as BT(Bacillus thuringiensis).
--Spray your squash plants at the soil line to control squash vine borer when
the plant first begin to flower. Continue through June 1st.
--Spray apple and pear trees with streptomycin when trees are in bloom to
prevent fire blight.To protect honey bees, do not spray trees with an
insecticide while they are in bloom.
--Begin weekly tree fruit protection program after the flower petals fall.
--Start a fungicide spray program for bunch grapes.
--Continue with weekly rose spray program to combat the black spot fungus.
Lawn care:
--It is too late for pre-emergence crabgrass control if the dogwoods have
begun flowering.
--Plant warm season grasses like Bermudagrass and centipede grass this month.
Zoysia is planted in May.
--Do not fertilize cool season lawns(tall fescue & bluegrass) until next
September.
Propagation:
--This is a good time to layer new plants.
Specific Chores:
--Visit the local garden stores or nursery to see what products and plants
are available.
--Mulch your landscape plants as needed. Pine needles, cypress mulch and pine
bark are good mulches.
--Organize your gardening supplies. Clean up, sharpen and repair tools. Check
equipment for proper operation.
