I'm just in the process of building a 6' by 6' raised bed in the garden (about 18" deep) and on digging down a bit I've discovered quite a few tree roots, how do people stop them getting in? I've heard mixed responses on the effectivity of certain methods such as plastic root barriers, digging trenches around the bed and even concrete (the latter two won't be an option for me). I'm thinking if I dig up the bed every year just before I'm about to plant, cut back any encroaching roots that have grown and then replenish the soil with nutrients that the tree roots may have stolen, my plants should be ok in the bed for 3 or 4 months until the season is over when I'll repeat the process the following year?
I don't mind the work of digging the soil up every year as long as it will stop my beds becoming overwhelmed with tree roots and keep my plants from being adversely effected, what are peoples experiences with this?
Cheers
Matt
