Tips for spring & early summer from Gary Long, Head Gardener at Trewithen

Head gardener at Trewithen Gardens, Gary Long, provides you with his top tips for trees and shrubs in spring and early summer:

  1. Mulch using organic matter to help prevent weeds and retain moisture.
  2. Feed trees, shrubs and roses with a balanced fertilizer such as Growmore or blood fish and bone. With Rhododendron pay attention NOT to mulch right up the stem/trunk. This could kill the plant, leave at least a 10 cm (4") gap.
  3. Check tree ties regularly to make sure they are not too tight and digging in or worked loose over the winter.
  4. Keep weeds under control, little and often is the key.
  5. Tie in climbing and rambling roses, making sure the stem is bent around the support to increase the chance of new shoots producing flowers lower down the stem.

Lawn care:

  1. Mow regularly lowering the height of cut gradually to the summer height.
  2. If composting clippings, spread in thin layers to speed up the composting process.
  3. Use "feed and weed" products to eliminate weeds and encourage lush new green growth.
  4. Edge lawns with either shears or a "Half moon".

  • Self-drive Visit to Trebartha, near Launceston

    We last enjoyed a visit to Trebartha in 2015 when many changes had taken place, such as the installation of a new hydro-electric plant and the large-scale removal of Rhododendron ponticum. Several years later and the area is gloriously settled. 

    Trebartha is located on the eastern side of Bodmin Moor and its gardens offer both natural and man-made features together with many fine views. Spanning 18 hectares, there is plenty to explore. This will be a full day visit so do bring a picnic lunch!

    Our group will divide into two for different guided walks in the morning and afternoon to view the ponds, cascades and terraces, and we shall stop to admire the beautifully-designed garden at Lemarne that is situated within the estate, en route.
