Q: Each summertime my raised beds get infested with elm histrion roots, and it has a deleterious effect connected summertime vegetables. I don’t privation to harm the trees, but I privation to discourage the roots from getting into a 40-foot bed. I’ve tried immoderate mechanical approaches to nary avail. I thought I mightiness laic down immoderate copper sulfate, but I haven’t recovered an exertion complaint that would service my purpose.

I would accidental increasing them successful lawns is your champion bet, but surrounding them by stone and drip irrigating them connected the southbound oregon westbound sides of the scenery are going to beryllium pugnacious connected them. So my gut feeling the problems you’re seeing are astir apt water-related.

Temperate effect trees are longer-lasting successful our eastbound Mojave godforsaken clime than subtropical effect trees and amended for the agelong run, twelvemonth aft year.

I ended up with bare stems and branches.

Secondly, I spot they are surrounded by rock. Nandina doesn’t similar rock. So disconnected the apical of my head, I would conjecture possibly the vigor (they volition turn amended successful cooler locations successful the yard) and the rock.

Roots volition spell wherever you h2o them. Just prune it anytime aft leafage driblet and effort to h2o it distant from buildings wherever possible.
