Default lavender (pruning)

wrote in message
...
I have a couple of lavender in big pots outside my front door, but they
haven't been watered as well as they probably should. They've been there
for 2 years and they didn't flower very well this year. (they don't get
an amazing amount of light, and I'm terrible for remembering to water,
and being by the front door they don't get much natural rain, on the
rare occasions it bothers to rain atm!)

I've just chopped them back quite a bit tonight (got to love the
gardening in the dark process at this time of year!) but they are ...
straggley looking and quite woody. How far should I cut them back? I
don't want to kill them, but if they're only going to perform as well as
this year (or worse) it might be better if I chuck them and get
something new for next year.

Any advice from lavender experts appreciated (other than "remember to
water them occasionally!" - I already got that one!)

Thanks



Hi Vicky,

Lavenders will not sprout from old wood, so if you're looking at bare wood
then I think you need to start again. Your lavenders will sprout again from
healthy green shoots that survive the winter, but not on bare wood below
that.

If you start again next year with fresh young plants, try and give them more
sun and a high potash fertiliser (not too much), both of which will
encourage flowering. After flowering, shear back the flowers to the point
where you can see good healthy green shoots lower down. If you do this
every year, you should stay in control for a while. Note, though, that
lavenders aren't long-lived plants and may need replacing after about 5
years.
