April To Do in the Garden

by Gary Crispell, EMGV

Hallelujah it is APRIL!! Real Spring is here. Statistical frost-free date is April 11. Get them tomato plants ready!! I mean if the seed packet says 65 days and you started the seeds in mid-February then you should be enjoying that first ‘mater sammich about Easter this year. Right? Well, maybe that’s pushing it a bit, but definitely by Mother’s Day. So, here’s a bunch of stuff to do while you are waiting for the tomatoes.

Lawn Care
This is the first month you may fertilize warm season grasses (i.e. Bermuda, centipede and zoysia) as they should be breaking dormancy soon. DO NOT fertilize cool season grasses again until fall.

Mow fescue and bluegrass at a height of three to four inches.

This is your last chance to put out pre-emergent crabgrass control. The deadline is when the dogwoods bloom. After that, the seeds will have germinated and pre-emergent by definition will no longer be a viable option.

Fertilizing 

  • See “Lawn Care.”
  • Fertilize any shrubbery that didn’t get fed in March.

Planting
Is this what everybody’s been waiting for, or what? By mid-month it is crazy time in the garden(s).

In the veggie garden sow, sow, sow. Melons, squashes, beans, cucumbers, pumpkins, peppers, tomatoes and corn. Presumably you have already amended the soil per your SOIL TEST recommendations. Be sure to plant enough to share with someone who might not have any at all.

Warm season grasses can be planted by the end of the month. Seeding is possible, though not recommended. Plugging and sodding are the better options with warm season grasses. Check out NC State Turf Files for detailed information on all lawn turf types.

Pruning

  • Remove any winter damage from shrubs and trees.
  • Wait to prune spring flowering shrubs [I.e. azalea (Rhododendron x hybrid), lilac (Syringa species), forsythia, spiraea, wiegelia, etc.] until after the blooms fade.
  • Prune fruiting shrubs [i.e. holly (Ilex species) and pyracantha] while they are in bloom to avoid removing all of this year’s berries.
  • If necessary, prune spring flowering trees [i.e. Bradford pear (Pyrus calleryana ‘Bradford’), flowering cherry (Prunus hybrids), redbud (Cercis species)].

Spraying

  • ALWAYS check plants for pests before spraying (except for borers which you won’t be able to see).
  • Be on the lookout for the following insect pests: azalea lacebugs, boxwood leaf miners, euonymus scale, hemlock & juniper-spruce spider mites. Spray only as needed following label instructions.
  • Spray iris beds for iris borers.
  • Treat cruciferous veggies (broccoli, cauliflower, etc.) for worms. An organic product containing BT is a good green choice.
  • Spray squash plants near the base of the stem at first bloom to control squash vine borers. Continue this procedure weekly until June 1 using only an appropriate insecticide.
  • Spray apple and pear trees while in bloom with streptomycin to control fire blight. Use two applications: one at early bloom and a second at full bloom. If we have a rainy spring consider a third application.
  • Begin weekly applications of fungicide on bunch grapes.
  • Continue a rose spray program (forever and ever).
  • Begin weekly fruit tree spraying after the flower petals fall off.

Other Exciting Things (or not) to Keep You Happily Outside in the Glorious Spring Weather
Mulch. Mulch, mulch, mulch. The possibility of a hot dry summer always looms large in the Piedmont of North Carolina. Shredded hardwood, pine needles (pine straw), shredded cypress and pine bark in its many guises are all good mulches.

When you are bored or desperate to remain outside to avoid painting the bathroom, dusting the ceiling fans, bathing the cat … whatever, there are and always will be weeds to pull. It is the environmentally sound way to get rid of them and the kids and/or grand kids can help (until they turn 11 at which time the helpfulness gene goes dormant).

It’s Spring y’all.  Go out and enjoy.
