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

  •Install wire “grow-through” plants supports on tall perennials and peony rings to give them inconspicuous support this summer.

  •For easy watering of many plants in the ground at one time, use a soaker hose or drip irrigation 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.

  •Check plants for spider mites and bagworms, especially evergreens.  Handpick bagworms and destroy them or spray with

Caterpillar Spray with Bt (Bacillus thuringiensis) or Spinosad.  Spray mites with Insecticidal Soap, Horticultural Oil, or FertilomeTriple Action.

  •Plant gladiolus, cannas, dahlias, caladiums, calla lilies, and elephant ears once soil is warm.  Amend soil with compost, manure, or peat moss 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.  

  •Use Beneficial Bacteria or Barley Straw bales or pellets to control green algae growth in water gardens.

   •Plant annual bedding plants and combination planters.  Use Metro-mix potting mix for a lightweight, well-drained soil for pots and hanging baskets.  When planting in the ground, use Mushroom Compost, Earthworm Castings, The Cow compost and manure, or Baccto Garden Soil.

 •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 nt at the drip line.

 •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.
