- Leave the sideshoots on the top third of the main stem unpruned, apart from the removal of dead, diseased or damaged growth.
Which is the hardiest ceanothus?
Ceanothus Hardiness
As far as my research goes the hardiest cultivar is 'Blue Sapphire' being given an RHS hardiness rating of H5 which should mean the plant can take short periods as low as -15°C. If you live in a more northerly or exposed part of the UK then this might be a more suitable choice.
Why is my ceanothus dying?
If the conditions are too windy / cold they can get leaf scorch. If the ground is too wet they simply die slowly. One common complaint is that the branches break and / or split. This is a feature of Ceanothus rather than a pest or disease.

Will a tree die if you cut branches?
When you cut off a tree branch, the tree develops a special callous tissue—along the lines of a scar—which covers wounds in order to keep out decay and disease. That tree's scars will always be there, but if you prune it properly, the tree itself can survive.
What is the best ceanothus?

Does ceanothus make a good hedge?
Ceanothus. If you're after an informal, flowering hedge, California lilac (Ceanothus) is a lovely choice. It's best planted in a sheltered, sunny position. Prune it lightly after flowering – as with any hedge pruning, you should wait until any nesting birds have departed before you cut.

How often do you water ceanothus?

How hard can you prune ceanothus?
However deciduous Ceanothus do tolerate hard pruning, carried out when plants are dormant between late-February and March, and can be pruned down to just above ground level if necessary. Response will be fairly slow; encourage strong regrowth by feeding and mulching in the spring after pruning.
Is my California lilac dead?
If the base of the branch has any hint of green to it, then that branch is still alive and you do not want to prune it away. If the branch is completely brown and has no leaves left whatsoever, it is completely dead and you should prune it away.
Can ceanothus grow in pots?
It's possible to grow Ceanothus in pots. In that case, you can bring it in a greenhouse or lean-in. It needn't be very warm, simply keeping frost away is enough. It does need to be well-lit, though.

Traditional orchards with trees which were large enough to walk or sit under and required ladders to pick the fruit were common at one time. They often served for both fruit production and grazing of animals, particularly sheep.
