Will pruning kill them?

Hello from tropical Shoreham-by-Sea!

I have some lavenders and a rosemary which have been in pots for years. Of course, I appreciate this is not ideal in any circumstances, but have no choice but to keep them in pots or dispense with them.

As you can imagine there is a lot of old 'wood' below any (new) growth. If I prune, losing all the growth, will this do for them or will new growth emerge?

Same with some buddleias, too, actually, although these are only a year or two old.

Many thanks

Lavender won't like being cut back to old wood. Easy to propagate from cuttings, so you might want to do that and then "replace" the old plant next year? Bext tio trim them after flowering to keep them in shape.

Not sure about Rosemary, but I think that might object to being cut back too.

Buddleias can be cut right back, and will put up strong vigorous shoots which will give a better show, I think, than an old plant that has been left to grow. Getting a bit late to do it though as it will make flowering late, and "less", if done late. Mid February would be ideal time.

 

Many thanks.

 

Hiya ennnceee,
Is your rosemary the bright blue flowering variety or is it the ordinary wishy washy one? Dont mean to offend but so many people grow rosemary without knowing they can also be brilliant flowering plants. Currently mine is floweriing and the flowers are BRIGHT blue and looking good. So, consider discarding your old plant and replace with a better variety like Benedon Blue. And after floweriing trim it back removing almost all the flowered wood and you will keep your plant looking bushier and floweriing longer.
Re buddleias there are now some dwarf varieties ESP good for pots....blue chip for example that flowers for ages and still attracting butterflies etc
