Be careful when you prune Californian lilacs. They need shaping up but might refuse to produce new branches from old wood. Different rules for evergreen and deciduous ceanothus shrubs apply.
Lavender is a versatile plant with many uses, but it still needs pruning and here's how to do that.
Lavender is one of those lovely plants that suits most aspects and offers beautiful flowers, foliage and scent. It can be used in a number of ways, with lavender hedges, shrubs and standards all being welcome additions to the garden. If you want to keep plants looking their best and producing lots of flowers, pruning is required. Otherwise you’ll end up with a very woody, sparse and spindly specimen.
Lavenders are best cut towards the end of the summer as the flowers begin to fade.
Snip lavenders into the shape you require, whether this is a hedge, a ball, a standard or simply a natural looking shrub. You should remove all of the flower stems and up to 3cm of the season’s growth.
On older and mature plants that you may need cutting back, you can afford to prune substantial quantities off, but make sure never to cut into old wood! Lavenders are unlikely to produce new growth if you prune back into woodier stems, even if you can see a few buds.
In older specimens that have got very misshapen and woody, you can try to rejuvenate them, but it’s often best to replace the plant.
