General Maintenance Of Gardens

  • Record harvest dates
  • Root cuttings of broad–leaf evergreen shrubs
  • Plant seeds of perennials, biennials and hardy annuals
  • Black sooty mold (BSM) is often observed on all kinds of crops, it is a fungus that feeds on the “honey dew” droppings of sucking insects (scale, aphids, white fly, mealy bugs), to be sure it is BSM, rub it off the leaf with your fingers and if the leaf is not damaged it is BSM, control sucking insects
  • Mildew time: with higher humidities of August and September nights, powdery mildew as well as several other leaf spot diseases will appear, mildew and leaf spots on Mahonia, Photinia, Holly, Skimmia, Pieris, Azalea, Lilac, Euonymus, Hydrangea, Maple, squash family and many others, control with sulfur or 1 T Baking soda and 2 T horticulture oil per gallon of water, test spray a few leaves before spraying whole plant, OR spray with compost tea
  • Check compost pile, may require watering, turn to prevent fly maggots, use yellow sticky boards for fly traps
