Neglected buddlea


By Mabrad

I have a buddlea at my new house which is 10ft tall and very long thin branches. When and how much should I cut it back?



Now is a good time, I would cut it back really hard right to the ground. Don't worry, it will come back nice and bushy.

I'd advise the same as above or cut it down to a little smaller than the size that you would like it to be, I cut mine into one stem and it's now a small tree shape where all of the side branches come off of one main stem

Blimey, ask a bunch of gardeners the same question and you'll get several different answers;-))

Assuming its Buddleia davidii, the usual procedure is to wait till March, then cut it down to within two inches of old wood on a yearly basis, and maybe removing some of the longer branches in autumn to prevent windrock over winter. However, given yours is such a size and may never have had this treatment, I'd cut it back to between 2 and 3 feet - whether you wait till March or not is up to you, because obviously, we haven't really had a winter so far, and there's only 3 weeks of February left anyway. Usually, by mid March, you can see new growth lower down the stems, which gives a good idea about how far to cut back, but that is likely already present, given the mild temperatures this year.

Works for B. x weyeriana, too. Strictly spring blooming species, such as B. alternifolia and B. globosa, should get similar treatment, RIGHT AFTER they bloom.

I 'd go to the 2 - 3ft height personally and then if you have lots more growth lower down then prune again next year lower down.

Monty Don was saying about Buddliea,prune some in April to produce flowers later in the year this helps to feed Butterflies for a longer period.I am going to do this, this year, i always prune to about 2or3 inches from ground seems to work.
