Pear trees aren’t grown in their own roots, instead the top of the tree is grafted onto different rootstock, which controls the size of the tree. So, pears can be grown in pots, but when doing this, ensure that they are on a dwarf rootstock.
Like apples, pears might need a pollinating partner from the same group. So, be sure to check, because it might be best to grow your pears in pairs. Although, you can get self-fertile types too.
When planting, dig a hole that is the depth of the roots and up to three times the diameter of the roots. When digging, break up the sides and base of the whole too so it’s not hard.
Then place the plant in the hole and add all of the soil, firming into place by stepping on it to ensure there aren’t any air pockets in the soil.
