Things to do in your
Mapesbury garden in August:
Cut back foliage and stems
of herbaceous plants that have died back.
Dead head i.e. Dahlias,
Penstemons and Roses to prolong flowering, otherwise plantís energy
will go into seed production.
Cutting back hardy geraniums
a little will stimulate new growth.
Once flowers have finished
on climbing/rambling roses that do not flower again/produce
attractive hips, they can be pruned.
Apply liquid tomato feed
weekly to prolong flowering of perennial and container plants.
Keep water topped up in
ponds and remove blanket/duck weed and plant debris.
Prune Wisteria and shrubs
i.e. Pyracantha, after flowering.
Lightly prune Lavenders and
Hebes after flowering.
Monitor plants for signs of wilting during dry spells and water
thoroughly. Keeping i.e. Camellias and
Rhododendrons well watered now will help them flower well next year.
Cut lawn once a week,
raising the mower blades during dry spells to reduce drought stress.
Prune ornamental trees i.e.
flowering cherries now, while there is less disease around to infect
the wounds and to give these wounds time to heal before winter.
Remove damaged and diseased branches, weak growth and unwanted stems
growing from the base of the tree. Where stems and branches cross or
rub against each other, remove the weakest to prevent possible
