How to Prune Lavatera
A hard frost can damage Lavatera and aesthetically, this can look unsightly. The best way to overcome this problem is to prune out the damaged branches in the spring. Also Lavatera can get leggy, and large, and to keep it looking fresh it is best to prune regularly in the spring.
Lavatera flower mid to late summer on the current years' growth. Prune in spring after all risk of frost has passed. Pruning is simple. You can either prune it down by around a third or half or, since Lavatera responds well to a hard prune, you can cut it down almost to the ground in the spring. As soon as the new shoots can be seen at the base of the plant, and the risk of frost has passed, cut back all the old wood and let the plant re grow on which will form the summer's blooms. Lavatera flowers best if it has an annual hard prune which also curtails the plant's natural tendency to become leggy.
Lavatera can also be an annual, such as the short-lived Lavatera trimestris 'Silver cup' which although classified as annual,it may survive the winter in a very sheltered spot. In northern or exposed areas, it would be necessary to bring under cover for the winter.
Lavatera is short lived, usually becoming very leggy and flowering less by around year 6/7 depending on conditions. It can be propagated from softwood cuttings in spring or summer.
Lavatera is an unfussy, easy to grow summer flowering shrub.
