As we head into prime planting season, here are a few things to keep in mind.
When potting up containers, use a high quality potting mix. This is usually a soilless mix with vermiculite, finely shredded organic matter and other ingredients that promote drainage. Potting mixes also are light weight. Since the mixes are soilless, be sure to fertilize regularly, according to the product label directions.
Containers have three basic elements: thriller, filler and spiller. The thriller is the largest or most dramatic plant, frequently the centerpiece or backdrop. Fillers are moundy-roundy and help fill gaps. Spillers cascade over the edges of containers.
Vegetables and Herbs
Don’t push planting. Warm season vegetables, such as tomatoes, eggplant, cucumbers and peppers, are not happy in cold soil. Wait until May 10 (or Mother’s Day) to plant these crops and to sow seeds for green beans, corn, squash and pumpkins.
Basil (Ocimum basilicum) is extremely sensitive to cold temperatures. It’s ok to plant parsley (Petroselinum crispum), sage (Salvia officinalis), thyme (Thymus) and other perennial herbs outdoors now.
If a perennial or ornamental grass has all of its new growth around the perimeter of a dead or sparse center, that’s a signal it needs to be divided. Lift the plant and slice off the healthy growth to transplant. Discard the dead center.
If you fertilized the lawn in fall, you probably won’t have to fertilize in spring or early summer. Doing so will increase mowing duties. Try to keep the lawn at about 3 inches high.
Annuals and Tropicals
Some annuals tolerate the cool temps of spring, but others, such as impatiens (I. walleriana) and geraniums (Pelargonium) do not fare well. Wait until mid-May to plant tender annuals and tropicals.
Try Something New
Lastly, try something new, whether it’s a vegetable or herb you’ve never grown, or a new perennial or annual. Trying new things in the garden keeps us growing.
