Why do you think they need fertilizer? What were the results of your soil test?

I just always fertilize them in the spring....I have never done a soil test. The nursery I go to never suggested that, just fertilize along drip line in the spring.

a well established shrub.. like a boxwood NEVER needs feeding .. IMHO ... you are just making your nursery guys boat payment.. and he is forwarding half to the fert salesman ... '

FORGET ABOUT THEM ...

roses do need feeding.. for the flower production.. and i would feed them accordingly .. and PRESUME.. the boxwood will steal whatever it needs .. or can get ..

please.. shrubs are not children.. they do NOT need to be fed ...

...and I'll bet they had the fertilizer right there handy for you to purchase too.

Fertilizing without an indication of need is probably more likely to cause harm than good. Improper application of fertilizer is a big problem in the horticulture world. I would ONLY apply fertilizer when I determined the NEED for such. That determination may be something as simple as noticing low vigor, but could be better guided by a soil test. If you want to apply something anyway, at least go for a mild formulation.

Thank you! Don't have to tell me twice, I won't touch 'em. One more thing I ca cross off my list of things to do!
