dying euphorbia

Hi,

My Euphorbia seems to be losing its top leaves. The flowers are still ok but the actual branches are suffering. Any idea what could be causing this? The border is a little overcrowded and it has been a bit windy in the past few weeks.
I did not prune this plant in the last 12 months.
I've recently used fertilizer on it.

thanks

 

In my garden euphorbias almost always fail in dry, sunny or windy spots. Any of these will kill it within a few months.


The use of fertilizer won't have done it any harm-unless you gave it more than the recommended dose.

 

Do we know what kind of euphorbia it is, as there are many, and they like varying conditions.

A picture would be good.
