Mesh planting baskets are available for your bare root plants. Since the baskets are relatively heavy an extra postage allowance is built into the price – they will be considerably cheaper if purchased at the nursery.
Tablets of compressed slow release fertiliser granules are also available. Use one per one to two litres of pot.
Hessian squares are not strictly necessary for fine mesh baskets, but some people like to use them if they already have baskets with a coarser mesh.
I regret that I cannot send soil or gravel – postage charges are excessive.
