Sandy Soil

• When planting Florida perennials in sand, amend the soil with organic matter such as compost or aged manure. Work several inches into the top 12 inches of soil.
  
  

Fertilizer Timing

• Only fertilize Florida perennials if they display signs of nutrient deficiency, such as yellowing or stunted growth. Apply a fertilizer with equal amounts of nitrogen and potassium and little or no phosphorous, such as 15-0-15, four times a year.
  
  

Controlled Release

• Controlled release fertilizers provide Florida perennials with a steady source of nutrients at a pace they can absorb. These fertilizers lessen fertilizer run-off and subsequent water pollution. Controlled release fertilizer brand names include Osmocote, Nutricote or Polycon.
  
  

Weeds

• Fertilizer will increase weed growth around Florida perennials. Control weeds before fertilizing and mulch to prevent the resurgence of weeds.
