Seasonal Tips for July

  • Cut back delphiniums and geraniums after the first flush of flowers to encourage a second flowering period.
 
  • These and late flowering border perennials will benefit from a top dressing of quick acting organic feed such as Sulphate of Potash.
 
  • Liquid feed containerised plants with Tomorite to keep flowering throughout summer.
 
  • Mulch borders to retain moisture and prevent weeds. 2-3 inches depth works best.
