Bare root season began as the Christmas season ended. Literally, as the last Christmas trees relinquished their space in nurseries, bare root stock occupied it. Most of this stock grew in Oregon, where winter weather is cooler, so was ready for digging and relocation prior to arrival. Now that it is here, the season for planting bare root stock is quite limited.
Almost all bare root stock is deciduous. It defoliated through autumn, so the stems are as bare as the roots are. Most bare root stock is fruit and nut trees, such as almond, apricot, cherry, plum, peach, apple, pear, persimmon and fig. Grape, currant, gooseberry, wisteria and rose are ready for planting bare root too. All are dormant, so unaware of the process.
They do not stay dormant for long though. They must be planted in their new homes prior to the end of winter, when warming spring weather stimulates new growth. They can not sustain such growth if their roots are unable to disperse into soil. This is why the season for relocating and planting bare root stock is so limited to winter. It relies on cool weather.
Fortunately, planting bare root stock is surprisingly simple. Soil amendment that prompts root growth away from confined root systems of canned (potted) stock is not so important. Since new roots grow directly from formerly bare roots into surrounding soil, amendment is only helpful for soil of inferior quality. Fertilizer will not be helpful until growth resumes.
A hole for planting bare root stock needs to be just big enough to contain the flared roots. It must be shallow enough to suspend any graft union above grade, without loose soil to settle below. Watering is only needed to soak and settle soil around roots, and will not be needed again until after the rainy season. Pruning removes crowded or damaged stems.
Of course, not all fruit trees are conducive to planting bare root. Evergreen plants are not as dormant during winter as deciduous plants are. Their roots are therefore less resilient to separation from the soil. Pitahaya, avocado and some citrus, which can be marginally vulnerable to frost in some climates, are more vulnerable after autumn or winter planting.
