April Gardening Checklist

  • April is a great time to plant trees, shrubs, and ground covers.
  • Most annual bedding plants, perennials, summer flowering bulbs (canna, dahlia, gladiolus), and annual flower seeds can be planted after danger of frost. This happens around mid-April in most of Oklahoma. Warm-season annuals, such as periwinkle and caladiums should, not be planted until May when soil temperatures are in the low 60s.
  • Prepare soil in flower and vegetable beds with Back to Earth Soil Conditioner.
  • Fertilize annual bedding plants at planting time with Earth Bud & Bloom Organic Fertilizer or with Osmocote Plant Food.
  • Preen Weed Preventer has a specialized formula to keep weed seeds from sprouting for three months around trees, shrubs, and flowers.
  • Set out tender vegetable and herb plants after April 15th, such as tomatoes and peppers. Wait a little longer for it to warm up before planting cucurbit crops and okra. Fertilize with Earth Tomato, Vegetable, and Herb Organic Fertilizer or Mater Magic.
  • Make first full feeding of Bermuda grass lawns with TLC Premium Lawn Food. Established shady lawn grass, such as fescue, should also be fertilized now.
  • Seed new areas or overseed existing areas of shady lawn grasses. Seed with TLC Premium Sun & Shade Mixture, Crossfire 4 Tall Fescue Seed, or Rembrandt Tall Fescue and apply Fertilome New Lawn Starter Fertilizer.
  • Apply Pennington Ultragreen Weed & Feed to control broadleaf weeds in the lawn.
  • Feed trees and shrubs with TLC Tree, Shrub, and Landscape Food or use Bio Advanced Tree & Shrub Protect & Feed to provide systemic insect control as well as fertilize.
  • Prune spring flowering plants as soon as they are finished blooming.
  • Feed roses with Bio Advanced All-In-One Rose & Flower Care.
  • Let spring flowering bulb foliage (daffodil, tulip, etc) remain as long as possible before removing.
  • If lawn grubs are present, treat with Bio Advanced Grub Control plus Turf Revitalizer.
  • Continue spray schedules for fruit trees using Bonide Fruit Tree Spray. Do not spray insecticides during fruit tree bloom or pollination may be affected.
  • Control of powdery mildew, leaf spot diseases, and blights can be done with early detection and regular treatment. Lace bugs, aphids, spider mites, bagworms, cutworms, flea beetles, etc. can start popping up in the landscape and garden later this month. Keep a close eye on all plants and bring samples of insects or damage to TLC Garden Centers for diagnosis.
  • Proper watering of newly planted trees and shrubs often means the difference between success and replacement.
