Now that Christmas trees have been moved out of the nurseries, it is time for bare root plants to move in! As the term implies, bare root plants have ‘bare roots’, lacking typical media (such as potting soil) which is typically contained in cans or pots. All sorts of deciduous fruit trees, roses, grapes and berries can be purchased bare root, either bagged with moist wood shavings, or out of the ‘sand boxes’ that they are heeled into in the nurseries. Even more are available from mail order catalogues. (Just check climate zone ratings for mail order stock.)
I purchased all of my deciduous fruit trees bare root mainly to save money. Bare root stock typically costs about half of what canned stock (grown in a nursery can or pot) does. Also, because bare root stock does not take up as much space as canned stock does, more varieties can be brought in and made available during bare root season.
Bare root stock gets established into the garden more efficiently than canned stock does. It gets dug, transported and planted while dormant; and can disperse roots into relatively uniform soil immediately after dormancy. However, stock that gets canned wakes up in spring in uncomfortably warm and confining nursery cans. After adapting to nursery conditions, it must then adapt to new garden environments, and disperse roots into soil that is very different from what it already rooted into.
Bare root stock should be planted as soon as possible after it leaves the nursery so that roots do not get too dry. If they can not get planted immediately, plants that were pulled from sand boxes in nurseries should get their roots heeled into (covered with) damp soil. Bagged stock in original packaging is safe for a few days in the shade.
Roots should be soaked a few hours before planting. I prefer to instead keep roots well watered for a day after planting. Broken or damaged roots should be pruned away before planting. Damaged and superfluous stems should be pruned away after planting.
Planting holes for bare root stock can be wide enough to loosen surrounding soil, but should be no deeper than necessary. Plants are likely to settle too deeply if the soil below is too loose. All roots should be buried while graft unions (the odd ‘kinks’ low on the trunks of grafted trees) remain exposed. Soil can be mounded firmly into a ‘volcano’ in the middle of each hole to spread roots over. Backfill soil can be amended lightly; not so much that it is too different from surrounding soil.
A basin should be formed around each new bare root plant so that roots can be soaked and settled in by filling the basins with water twice. Bare root plants are initially dormant and lack foliage, so do not need water again until they develop foliage, and the soil gets dry in spring. Besides, rain and cool weather will keep the soil wet through winter.
