Our Gardening Calendar

Mississippi State Extension Service Garden Calendar
North Florida Gardening Calendar

January

  • Big Garden
    • Till in cover crops 6-8 weeks before spring sowing.
  • Yard Garden
    • Replant green onions when they arrive late in the month
    • Replant lettuce, bok choy, swiss chard.
  • Yard
    • Prune Crape Myrtles
    • Feed Citrus per IFASBalanced fertilizer formulations such as 6-6-6 or 8-8-8 are suggested, but other complete fertilizers can also be used. Fertilizer applications should be split between three to five applications a year; i.e. Jan, Mar, May, July, Sept.
    • Daylilies – Cut out rust, spray with contact and systemic fungicide and feed drench.
    • Control persistent scale insects on citrus, shrubs, camellias, and deciduous fruit trees; apply horticultural oil while plants are dormant.  http://edis.ifas.ufl.edu/ep451
    • Add nitrogen to the compost pile
    • Peach trees – pruning methods used in the third and fourth dormant seasons as peaches are pruned to an upright but lateral canopy with an open center having three to four primary scaffold limbs branching out to five or six secondary branches and smaller twigs four to five feet above ground. From IFAS
    • Prune Pear Trees from Starke Bros.
      • For your branches: choose wide 10 o’clock and 2 o’clock angles.
      • Pruning to a bud. Make sharp, clean cuts close enough (about 1/4 inch) so you won’t leave a clumsy stub that’s hard to heal over. Stay far enough above the bud so it won’t die back. Slant the cuts and the new growth will develop beautifully.
      • Every branch has buds pointed in various directions. Since you want vigorous new growth to spread away from the center of the tree, make your cut above a bud that’s aimed outward. This helps your tree grow into a spreading shape.

February

    • Prune Azaleas in late winter before growth begins for the season, improve the form of the bush by shortening stems that jut out of place.

    • Blueberries – From IFAS immediately after fruit harvest:
      • Once the plant is four to five years old or older, a general rule is to remove about 1/4–1/5 of the oldest canes each year (usually 1–3 of the oldest canes). This will result in continuous cane renewal so that no cane is more than three or four years old.
      • Mature plants are usually topped by removing several inches to a foot or more from the top of the canopy immediately after fruit harvest. This stimulates new growth that will produce next year’s crop and prevents plants from becoming too tall.
  • Pond

November

  • Big garden
  • Yard Garden
  • Yard
    • Spread Pendulum 2G Granular Herbicide prior to night time temps in the high 50’s; i.e. before germination of Burweed.
  • From IFAS and MS State Ext.
    • Camellias: Add some of the new cultivars for bright spots of color in winter. Disbudding, or removing some buds now, ensures larger blooms later. SeeCamelliashttps://edis.ifas.ufl.edu/topic_camellia
    • Flowering trees: Consider planting an ornamental Taiwan cherry (Prunus campanulata). Late winter brings pink blooms. SeeThe Florida-Friendly Landscaping™ Guide to Plant Selection and Landscape Designhttps://ffl.ifas.ufl.edu/homeowners/publications.htm

December

  • Big garden
  • Yard Garden
  • Yard
    • Camellias – Fungicide for petal blight in the backyard as recommended here.  Applications can be made as a ground spray or sprayed directly on flowers. Ground applications should be made in the fall or early winter before flowering by drenching the soil around plants. For control, a 10-foot circle of fungicide must be applied to the soil surface around each plant (usually 2 or more quarts). Ground applications prevent apothecia development, so spores are never released to infect blossoms. Preventative applications can also be made directly to open flowers. Applications should be initiated when buds begin to show color and repeated based on the labeled fungicide interval. Captan and mancozeb can be used.
    • Move or transplant blueberry bushes from Mid December to mid-February. See IFAS for more info.
