September Garden Tips

  • Apply aluminum sulphate around the base of hydrangeas to keep them blue; for pink blooms use dolomite lime.

  • Continue deadheading annuals and tidying up perennial borders as plants finish flowering.

  • Sow green manure crops of fall rye or legume mix in vegetable beds.

  • Give hedges a final trimming before winter.

  • Excellent time to reseed and renovate an uneven lawn or install a new one using turf or seed.

  • Check out flowering ornamental grasses, Miscanthus (Maiden Grass), Panicum (Blue Switch Grass) and Stipa (Feather Grass) are at their peak this month.
