Rather depends on which plants you are growing GD.
Strong rooters such as Lilly/Iris, etc will make their way out of the basket regardless. The more genteel types you can, to an extent, keep them contained simply by using Hessian or thin weed membrane fabric.
All of them will need a certain amount of checking over and cutting back unless you have acres of water - in that case, you should be OK for a few years
