May Gardening Tips

EDIBLES:

  • May is the time to plant in the Pacific Northwest. Our Average Last Frost Date is May 15th, after that date is safe to plant outdoors:
    • Tender Herbs like Basil, Cilantro, Scented Geraniums and Tender Sages.
    • Tender Tropical Herbs like Lemon Grass and Lemon Verbena.
    • Warm Season Vegetables like Corn, Cucumbers, Eggplant, Melon, Tomatillos, Tomatoes, Peppers, Pumpkins, Squash and Watermelon.
  • Oregon has heavy clay soils which discourage root growth and inhibit nutrient uptake. Amending the soil with Black Forest Compost to break-up clay; letting plants freely gather nutrients and water, allowing them to reach their full and productive potential.

  • Spring is an excellent time to plant perennials to get them established before the heat of summer. For vivacious color that returns year after year choose perennials:
    • For Vivid Blooms: Black-Eyed Susan, Echinacea, Geum, Hardy Fuchsias, Hardy Geraniums, Lilies, Wallflower and many others bring exceptional color.

  • Spring is the perfect time to plant shrubs to get them established before the heat of summer. For a complete look, compliment plantings with striking shrubs:
    • Azaleas, Hydrangeas, Rockrose, Rhododendrons, Roses and Weigela are just the beginning of fantastic blooming shrubs.
    • Barberry, Euonymus, Leucothoe, Mexican Orange and Pieris are just a sampling of shrubs with stunning foliage.

FERTILIZE:

  • Fertilize Trees and Shrubs with an appropriate fertilizer:
    • All Purpose Fertilizer – for trees, shrubs and perennials that are prized for their foliage.
    • Azalea, Rhododendron & Camellia Fertilizer – for the shrubs listed plus conifers, maples and blueberries which prefer acidic soil.
    • Citrus Fertilizer – for citrus and other heavy feeding, acid-loving plants like Gardenias.
    • Flower Garden/Bud & Bloom Fertilizer – to promote ample, luscious blooms in shrubs, perennials and annuals.
    • Fruit Tree Fertilizer – to promote verdant foliage and a bountiful harvest with fruit trees.
    • Vegetable & Tomato Fertilizer – for all edibles including berries, perennial vegetables (like artichokes, rhubarb and asparagus) and herbs.
  • Fertilize Hydrangeas to encourage vigorous growth and lush blooms.
    • To make Hydrangeas PINK add LIME.
    • To make Hydrangeas BLUE add ALUMINUM SULFATE or HYDRANGEA BLUING.
    • To make Hydrangeas WHITE test the soil and adjust the pH to make it neutral.
  • Apply Lime:
    • Plant Cucumbers, Eggplant, Melons, Peppers, Pumpkins, Tomatoes, Summer Squash and Winter Squash with Lime, which adds much needed calcium to the soil ensuring a productive harvest.
    • To Pink Hydrangeas, Lilacs, Daphne and other plants that prefers Alkaline (“Sweet”) soil.

TIDY & TRIM:

  • As spring flowering bulbs like Tulips and Daffodils fade, wait for their foliage to yellow then cut down the foliage to the ground.
  • Deadhead Rhododendrons & Azaleas just after bloom by removing flower clusters; simply snap at the natural break point just above where the new leaves emerge. This is also the time to prune to shape the Rhododendrons and Azaleas too; pruning after bloom ensures an unaffected flower set for the following year.
  • Prune other spring flowering shrubs like Lilacs, Forsythia and Flowering Quince after bloom. These vigorous durable shrubs can be hard-pruned to remove any dead wood, control size and maintain shape. In addition, regular thinning every two to three years should also be done to encourage fresh growth and reduce the potential for disease.

LAWN CARE:

  • Remove moss from lawns with Moss Out or Moss Out Plus Fertilizer. Plus remove moss from hard surfaces with Moss Out Roofs and Walks this special formulation keeps walkways and roofs safe and tidy, without staining.
  • Fertilize the lawn applying a Weed & Feed, available in Organic and Conventional formulas.
  • Apply Lime which adjusts the pH of soil, making nutrients more available to the grass and helping control moss.
  • Aerate and Thatch the lawn every other year to encourage a lush, healthy, vigorous lawn.
