Garden Calendar - June





Spray roses susceptible to black spot disease every week with Fertilome Systemic Fungicide, Triple Action, or Copper Soap Fungicide.  1 Tbsp Horticultural oil mixed with 1 Tbsp baking soda in 1 gallon water is also a good organic spray.

  •For easy watering of many plants in the ground at one time, use a soaker hose for 2 hours every 7-10 days when soil is dry. Watering slowly and deeply less often at the roots with a dripping soak  is better for plants than watering overhead with a sprinkler or watering can. For individual plants, water 6 minutes per foot of plant height with a slow stream of water from a garden hose.

   •Check plants for spider mites and bagworms, especially evergreens.  Handpick bagworms and destroy them, or spray with Fertilome Caterpillar Spray with Bt (Bacillus thuringiensis) or Fertilome Spinosad. Spray mites with Insecticidal Soap, Horticultural Oil, or Fertilome Triple Action.

  •Plant gladiolus, cannas, dahlias, caladiums, calla lilies, and elephant ears now that the soil is warm.  Amend soil with compost and manure, and use Hi Yield Bone & Bloodmeal mixed in the soil when planting.  

  •Use Spreader-Sticker with all liquid insecticides and herbicides except oil sprays to help the product stick to the leaves and increase absorption and effectiveness of the sprays.  

  •Plant perennials for summer color and to attract butterflies and hummingbirds. Use Mushroom Compost, Earthworm Castings, The Cow compost and manure, or Baccto Garden Soil when planting and use Fertilome Root Stimulator every 2 weeks.

  •Fertilize azaleas, rhododendrons, hollies, magnolias, dogwoods, evergreens and others with Cottonseed Meal. Use 1 lb. cottonseed meal per foot of plant height and spread evenly underneath the plant at the dripline.

  •Use Neptune’s Harvest Fish Fertilizer or Fish/Seaweed Blend every other week to feed bedding plants, vegetable gardens, perennials, fruits, and other plants throughout the summer for vigorous growth.

  •Prune spring blooming shrubs like azaleas, forsythia, lilacs, weigela, spirea, etc., to shape them or reduce their size.  

  •Deadhead perennials that have finished blooming such as irises, peonies, and daylilies by removing the flower stalk so they do not put all their energy into producing seeds.

    •Mulch trees, shrubs, perennials, roses, fruits, and annuals with shredded hardwood, cypress, or cedar mulch to inhibit weed growth and help hold moisture in the soil.

    •Keep water gardens clean and provide oxygen to fish by placing potted oxygenators in the bottom of the pond.  

   •Feed roses, perennials, and shrubs with Bone & Bloodmeal for continued good growth.
