Pruning in March

  • Olive tree (Olea): Prune inward growing and dead branches. Vertical branches may be pruned rigorously; horizontal branches retain the characteristic shape.
  • Oleander (Nerium): Prune only for shaping or to limit size.
  • Hydrangea: Rejuvenate the plant by removing 1/5 of the old branches and dead flowers.
  • Butterfly bush (Buddleja): Prune to 30-50cm above ground for maximum flowering.
  • Clematis: Cut back to 20-25 cm above the ground; the plant will grow back naturally.
  • Roses: Remove woody, old branches and prune above outward-facing buds.
  • Winter jasmine (Jasminum nudiflorum): after flowering in March, to 3 to 4 pairs of leaves. A pair of leaves is that part of the branch where two leaves grow opposite each other. One on the left and one on the right at approximately the same height. 
  • Lavender: Drastic pruning (1/3 of the plant but keeping some leaves) should be done from mid-March to early April, so that it will bloom profusely in the summer. 
  • Berry bushes: Most berry bushes can be pruned in the spring. 


Small jobs

  • Sow annuals indoors or in a greenhouse.
  • Check potted plants for growing space and repot if necessary.
  • Wait to put container plants outside because of possible frost.

  • Give outdoor plants organic fertilizer and houseplants plant food.
  • Leave leaf piles for hibernating hedgehogs.
  • Check and clean pond pumps and filters and remove dead plants.
  • Dig over the vegetable garden, but not too deeply to protect soil life.
  • Knot willows before mid-March.
