April is the perfect time to start planting cool-season crops like peas, lettuce, and radishes as the weather warms up. It’s also a great month for preparing the soil, pruning winter-damaged plants, and adding compost for a healthy garden. Read on for more gardening tips!

Timely Tips
- Turn on your irrigation system and inspect for adequate coverage and any leaks or issues. Use the Qui-Key Master Key for easy DIY irrigation turn on and off. Learn more about the locally designed and produced Qui-Key tool here.
- Release beneficial nematodes when nighttime temperatures are above 45 degrees for control of soil dwelling pests such as root weevils. Ladybugs, praying mantids & lacewings can be released at the same time to control a wide range of garden pests.
- Start a new lawn from seed or repair an existing lawn; cover seed with G&B Organics Planting Mix and use Bird B Gone Flash Tape or Dalen® Guard’n Eye® Reflective Disks to protect from birds. Moana recommends Jonathan Green Black Beauty Grass Seed.
- Core aerate manually with a Coring Aerator, then fertilize your lawn if you haven’t yet done so. Use G&B Organics Lawn Fertilizer. If you have weed problems, use Hi-Yield Turf & Ornamental Weed & Grass Stopper or Jonathan Green® Corn Gluten Weed Preventer.
- Install Mason Bee tubes in a morning sun location to help with pollination of fruit trees.
- Moana recommends Bonide Weed Beater Ultra for superior performance in cool weather on broadleaf weeds – i.e., dandelions, wild mustard and more.
- Use Monterey Remuda Extended Control to kill unwanted plants where you don’t intend to plant for at least one year.
- Prepare planting beds by cleaning up debris and incorporating three inches of organic matter, like G&B Organics Soil Building Conditioner or G&B Organics Purely Compost into the soil. Mulch existing plantings with 2-4” of compost as well.
- Continue watering trees, shrubs, lawns, perennials and containers.
- Moana recommends Barenburg White Clover as an excellent ground cover for gardens and lawns, as it helps improve soil health by fixing nitrogen. When planting white clover seeds, make sure to sow them in early spring or fall for optimal germination. Lightly rake the soil to create a fine seedbed, then sprinkle the seeds evenly over the area. For best results, lightly press the seeds into the soil by walking over the area or using a roller. White clover thrives in well-drained soil and moderate sun, but it can tolerate some shade. Water the seeds regularly, but avoid soaking them too much, as they prefer a slightly drier environment once established.
- Continue planting fruit trees – pear, apple, peach, cherry, nectarine, apricot & plum.
- Use Codling Moth Traps, according to directions, to determine when and how often to treat pear and apple trees with Captain Jack’s Deadbug Brew.
- Feed fruit trees with a balanced fertilizer like G&B Organics Citrus & Fruit Tree Fertilizer.
- Feed trees and shrubs that have been planted more than a year with G&B Organics Paradise Fertilizer, a time release pelletized toss & go fertilizer with beneficial mycorrhizae.
- Moana recommends Fertilome Tree & Shrub Drench if insects have been a problem in the past. Please always follow all label directions when using pesticides.
- Inspect trees and shrubs for insect and disease problems; treat immediately with appropriate product.
- Prune spring flowering trees and shrubs immediately after they have bloomed.
- Continue planting dormant roses.
- Remove tree stakes and ties from trees & shrubs planted a year ago or longer.
- Dalen Insulated Plant Protectors are designed to shield plants from frost, snow, and freezing temperatures ensuring they thrive year-round. Simply slip it over your plant, secure it with the built-in drawstring, and watch it work its magic. No more struggling with cumbersome covers or expensive heating systems.
- Plant asparagus crowns, potatoes, onions and other cool season vegetables and fruit trees now. Use Dewit N-Sulate Frost Protection Blankets or Dalen Insulated Plant Protectors to cover your lettuce and other cool season vegetables, allowing you to harvest sooner in our short, sporadic season.
- Plant strawberries and pinch off first year flowers.
- Fertilize raspberries and other brambles with G&B Organics Citrus & Fruit Tree Fertilizer.
- Plant tender veggies with G&B Organics Harvest Supreme and Dalen Insulated Plant Protectors which allows you to start tomatoes, peppers, squash, etc., 6-8 weeks earlier without fear of freezing. Plants will be healthier and produce up to twice the fruit 30-40 days earlier. Fertilize with G&B Organics Tomato Vegetable & Herb Fertilizer.
- Plant summer bulbs with G&B Organics Fish Bone Meal or Happy Frog Steamed Bone Meal. Moana Nursery has a great selection of summer bulbs, including gladiola, dahlias, canna, lily of the valley and others to enjoy this season.
- Fertilize spring blooming bulbs with Happy Frog Steamed Bone Meal as new green growth emerges and when they finish flowering.
- Pull back mulch from around the crowns of perennials.
- Plant cool weather color, perennials, ornamental grasses & roses.
- Now is the time to plant your perennials that will bloom later this season. Choose from delphiniums, poppies, lupines and others to add to your perennial garden.
- Divide mature summer and fall blooming perennials (except for daylilies, oriental poppies & iris) when they are 4-6 inches tall.
- Prune, feed and mulch your roses; Moana recommends G&B Organics Rose & Flower Fertilizer or Fertilome Rose & Flower Food plus Systemic (feeds & protects). Mulch with G&B Organics Harvest Supreme, being sure to keep mulch 3 inches from the canes.
- Deadhead spring bulbs once they’ve finished flowering and feed again with G&B Organics Fish Bone Meal or Happy Frog Steamed Bone Meal. Allow foliage to wither completely before removing.
- Stake peonies to support blooms when they reach 10” in height.
- It’s not too late to start tomatoes, other warm-season vegetables & annuals from seed indoors.
- Attend to your houseplants by adding SUPERthrive each time you water (1 drop per cup or ¼ tsp. per gallon).
- Repot pot bound houseplants with G&B Organics Blue Ribbon Blend potting soil and water thoroughly with SUPERthrive as noted above.
- Begin fertilizing houseplants with Fertilome Houseplant Hero or FoxFarm Grow Big Liquid Plant Food or Fertilome All Purpose Water Soluble Plant Food as new growth begins.
- Repot pot bound houseplants with Blue Ribbon Blend Potting Soil.
- Water is the best way to attract birds and wildlife to your yard and increase the chances of spotting an unusual migrant visitor at your feeder station.
- Continue to supply fresh water and change it every 5 days to keep it clean. To prevent the chance of disease, clean birdbath weekly with a weak bleach solution and rinse well.
- If you have a water feature, turn it on as soon as the weather permits.
- Reduce window strikes and potentially harmful territorial behavior of birds at windows with UV window decals and Stop Bird Attack.
- April is a nest building month; place nesting materials out for them now and consider a Wild Birds Unlimited birdhouse for wrens, bluebirds or woodpeckers if they are visiting your yard.
- Roosting boxes can supply a shelter for some nesting birds; doves and robins are quite likely to use a fabricated nesting shelf.
- Help celebrate Earth Day by installing an eco-friendly bird feeder or nest box made from recycled milk jugs.
- Install a customized Wild Birds Unlimited bird feeding station where you can easily watch the birds it attracts. To make your station especially attractive, plant bird-friendly flowers and shrubs nearby.
- Provide mealworms to attract nesting birds to your yard and for the feeding of new nestlings.
- Offer WBU Nesting SuperBlend®, Mealworms, WBU Bark Butter Bits®, Bugs & Bits®, Peanut Butter n’Jelly® Suet Dough or WBU Bark Butter® to provide the extra calcium needed during nesting season. Bark Butter® products are popular with parent birds and nestlings alike!
- Consider adding our new Bugberry Blend to your feeders as an attractive treat for fruit and insect eating birds.
- Hummingbirds are HERE! Get those hummingbird feeders out in order to take care of new visitors. Change nectar at least weekly until they begin feeding regularly when you’ll frequently have to refill! Orioles will follow soon – be ready with oranges, grape jelly and sugar water.
