Seasonal Gardening Calendar
Time to start moving your houseplants outdoors gradually. April winds will keep your wind chimes tinkling. And, make sure to plant your Easter lilies outdoors so everyone can enjoy them for the holiday.
APRIL Week 1
April Shopping List
Divide your ferns
Divide over-wintered baskets of Boston fern into four sections. Plant new hanging baskets using two sections of fern in each.
Clean up Bermuda
Green grass in a Bermuda lawn is probably Poa annua (annual bluegrass). You can try digging it out but, better yet, make a mental note to put out weed preventer next September.
Spray for weeds
Prepare spots where you intend to sod by first killing all weeds present. Use glyphosate (Roundup) or glufosinate (Finale).
Check for bugs
Examine the backside of euonymus and holly leaves for the white crust that signifies scale insects. Thoroughly spray leaves with horticultural oil.

APRIL Week 2
It is safe to plant tomatoes, peppers and eggplant in your garden now that the soil is warm.
Clean up azaleas
Remove withered flowers from florist’s azaleas you receive for Easter to prolong their blooming. Spray them with insecticidal soap if you have had azalea lace bug problems in the past.
Start moving plants outdoors
Move houseplants outdoors gradually. Never place them in full sunshine; filtered shade is best.
Lime your lawn
It’s never the wrong time to lime your lawn. Forty pounds per 1000 square feet is approximately enough but a soil test can tell you exactly what you need.
APRIL Week 3
Remove tree supports
Remove guy wires from your fall-planted trees. Trees that move with the wind grow stronger than those supported for more than a few months.
Plant Easter lilies
Plant Easter lilies outdoors after removing their faded blooms.
Mulch your tomatoes
Mulch tomatoes immediately after planting to prevent early blight fungus from splashing from the soil onto the leaves.

Water and fertilize houseplants
Water houseplants more frequently with the onset of more hours of sunshine and new green leaves. Begin monthly feedings with houseplant fertilizer.
APRIL Week 4
Plant the seeds of annual flowers such as marigold, cosmos, zinnia and celosia. Mix lots of soil conditioner in beds to help them be drought tolerant.
Hang a garden chime
Hang garden chimes on a tree branch so the wind keeps them constantly tinkling.
Plant corn, bean and pea seeds now. Use a soaker hose to water vegetable rows – you’ll prevent disease and weeds plus save water.
Sharpen your mower blade
Sharpen or replace your mower blade now that lawn grass has begun growing rapidly. Check the mowing height on a flat surface.
Check for aphids
Look for aphids clustered at the tips of fast-growing crape myrtle branches. Blast them off with a water hose and give a ground-dwelling spider a nice lunch.
Plant dahlias, elephant ear, gladiolus and caladiums now.
