Plants in borders are often planted well apart which provides little
mutual support. Consequently they require additional propping.
Nutrient-rich soils exacerbate the problem, encouraging soft growth,
and modern hybrids are developed with larger flowers, greater vigour
and increased height in mind, making them top-heavy and more likely to
fall over.

Stakes should ideally be in place in spring, before plants havemade
too much growth. Later staking is difficult as plant growth is more
advanced and can easily be damaged.

Material.

Bamboo canes and metal rods and frames (plastic-coated if preferred)
are widely available. Grid or grow-through supports are also
available, along with plastic and galvanised meshes. Birch or hazel
pea sticks and rods make a more natural framework.

3-ply soft twine is suitable for small plants, but 5-ply soft twine is
required for larger specimens. Don't tie-in plants too rigidly; they
should be able to move in the wind. Rubber clips are available for
holding supports together. Cane tops should be covered with rubber eye
protectors.

Method

Upright clump-forming perennials (e.g. Delphinium ) can have
galvanised wire-mesh cylinders placed over them. Bushy perennials such
as Campanula and Helenium grow well in simple circular frames, and top-
heavy plants such as herbaceous Paeonia and Dahlia are well-suited to
grid supports. Pea-sticks are useful for both front- (e.g. Penstemon )
and back-border plants (e.g. Inula racemosa ), whereas tall obelisks
are useful for roses, Clematis and Lathyrus . Support heavier stems of
large perennials, such as Crambe cordifolia with canes or rods.
