A sustainable alternative; that must be more expensive?

Actually, the Keeper system is significantly cheaper in procurement and installation than tree stakes, and has a limited aftercare.

Is the Keeper system suitable for trees with a brittle root ball?

Yes it is. If that is the case you can strengthen the root ball by securing an extra piece of NatuRope around it after regular installation. We do advise trees with a properly rooted root ball for better anchoring, better growth and a lower tree mortality rate.
