Monthly Garden Tips - APRIL

General Gardening Tips

  • Color is everywhere this month! April bloomers include azaleas, rhododendrons, dogwoods, redbuds and magnolias.

  • Other landscape plants with interest now include andromeda, camellia, daphne, forsythia, pussywillow, weigela, Harry Lauder's walking stick and spirea.

  • We recommend fertilizing annuals, perennials and flowering shrubs and trees with Dr. Earth Flowering Plant Food. This product contains slow-release nitrogen, sulfate of potash, iron and other micro-nutrients for overall plant growth and development.

  • We recommend feeding all your evergreens (hollies, boxwoods and yews) and deciduous trees (maples, oaks and ash) with Dr. Earth's organic fertilizer. This product contains slow-release nitrogen, sulfate of potash, iron and other micro-nutrients for overall plant growth and development.

  • For all your new spring plantings, we recommend using Dr. Earth Starter Plant Food at the time of planting. This will encourage root growth and help get the plant off to a vigorous start.

  • Time to plant fruit trees and grapes. Some fruit trees need a pollinator (two different kinds that bloom at the same time).

  • Before adding fresh mulch to your flower beds, apply a weed preventer such as Preen.

  • If you haven't already, prune roses and cut back liriope and ornamental grasses before new growth begins.

  • Plant pansies, violas and primroses for early spring color in the landscape.

  • Fertilize bulbs with a slow-release fertilizer such as Dr. Earth Bulb Food as they emerge.

  • Start tuberous begonias and canna bulbs indoors to be ready for May planting. We have a great selection of summer flowering bulbs in stock.

  • Beaver Bark has hundreds of varieties of beautiful perennials to choose from with fresh shipments arriving this month.

  • Apply Preen or Organic Weed Control to garden beds to prevent weeds from germinating.

  • Potted roses arrive in late April at Beaver Bark gift & Garden Center. Plant now for beautiful color all summer long.

  • Plant gladiolus every week up to July 1st and enjoy flowers all summer and fall.

  • If you have a pond in your landscape, begin feeding your fish when water temperatures are above 50 degrees. You can prevent algae in your pond with floating barley bales and beneficial bacteria.

Pest Controls

  • Many pest problems begin to appear in April. If you have plants that you suspect may be facing a pest problem, bring in a representative sample and speak with our plant specialists. We will diagnose the problem and recommend the appropriate control. Listed below are some of the problems that can appear this month along with the proper controls.

  • Watch out for tent caterpillars in cherries, crabapples and plums. When the caterpillars are small (less than 1" long), you can spray with an organic product such as Dr. Earth Insect Spray. These products are only toxic to caterpillars. If you wait until the caterpillars are longer than 1", however, you will need to spray with Sevin.

  • Bark beetles and borers can affect landscape plants such as pines, fruit and shade trees. Use Borer Miner Killer.

  • Leaf gall and flower gall on azaleas can be controlled with Copper Sulfate.

  • Boxwood psyllid can be controlled in late April by spraying Systemic Insect Killer or Sevin.

  • Juniper scale can be controlled in April using Malathion.

Fruit and Vegetable Gardens

  • Time to plant the following vegetables outdoors: Asparagus, Broccoli, Brussels Sprouts, Cabbage, Chinese Cabbage, Cauliflower, Celery, Chives, Collards, Horseradish, Kale, Lettuce, Mustard Greens, Onions, Parsley, Parsnips, Peas, Potatoes, Rhubarb, Spinach and Swiss Chard.

  • Mix organic matter into your vegetable garden. We recommend Dr. Earth organic soil conditioner as well as lime and vegetable food.

Lawns

  • April is a great time to get your lawn into shape by liming, seeding, fertilizing and preventing crabgrass and other weeds.

  • Seed the lawn with a good quality grass seed that is suited for the conditions of your lawn.

  • If needed, lime the lawn to raise soil pH. Lawns prefer a pH range of 6.2 - 6.8. If your tests show a level lower than 6.0, or you have not limed the lawn in the past two years, you should lime at the rate of 50 lb. of lime per 1,000 square feet of lawn area. This will raise the pH 1/2 point. If you need to apply more lime, wait six weeks between applications.

House Plants

  • Feed houseplants with a good quality indoor plant food such as Osmocote (slow-release granular).

  • If needed, re-pot root bound houseplants to a larger pot. Beaver Bark stocks a full line of containers, including terra cotta, wood, concrete, ceramic and plastic. Use Beaver Bark Potting Mix when repotting houseplants.

  • Check the leaves of your houseplants for insects or any other problems. If needed, bring in a representative sample and one of our plant specialists will diagnose the problem and recommend the appropriate control.
