There are several advantages to planting bare-root trees: they are usually less expensive, easier for gardeners to transport, and they will grow their roots entirely into native soil (rather than having to transition from potting mix into dissimilar native soil). Also, the ideal time to plant bare-root trees is in the winter, when you have a break from the demands of other garden chores.
Once the planting site has been prepared, it's time to select the tree. Trees with a trunk diameter between one-half and five-eighths of an inch usually become established faster than larger or smaller stock. If the root mass is visible, be sure it is well balanced, not “one-sided.” Remove any dead or damaged roots before planting. It is best to plant bare-root trees immediately after bringing them home, but if this is not possible, the roots should be covered with sawdust or compost and kept moist until planting.
Clear an area about 3 feet wide around the tree, eliminating weeds and grasses to keep them from competing with the tree for water and nutrients. To prevent future weed growth and conserve moisture, a layer of mulch 3 to 6 inches thick can be placed around the tree. However, to avoid crown rot, keep the mulch several inches away from the tree trunk. As a final step, remove the top of the tree by pruning back to a single trunk approximately 24 inches tall and paint the bark of the entire tree trunk with white interior latex paint diluted with water (two parts water to one part paint) as a whitewash to reflect excess heat. This prevents sunburn and the resulting invasion of wood-boring insects that can stunt or kill the new tree.

Winter is an ideal time to plant a fruit tree. Although it requires some patience, success is best using bare root trees. There are many advantages: the trees are lighter and easier to handle; you can get a good look at the roots; they cost less than leafed-out potted trees; the tree is dormant and less apt to be stressed by handling; and the roots don't have to adapt again to new soil. The main disadvantage is that you should get the tree in the ground within a few days after purchase, and it may take 2–3 years before some trees produce fruit.
Fruit trees are an investment and deserve some thoughtfulness to ensure you plant the right tree (appropriate for your climate zone) in the right location (good drainage, minimum 6 hours sun per day). Digging the planting hole before buying the tree will let you check for drainage and an adequate amount (2–3 feet deep minimum) of soil. Here is a website showing how to test soil including drainage: https://marinmg.ucanr.edu/BASICS/SOIL_813/evaluate/
Selecting a healthy bare root tree is critical to get your investment off to a good start. Buy your tree from a reputable nursery that has a wide selection. You don't want a tree with roots that have been in a container too long. These roots may be kinked and will look like they are circling the root ball. These roots tend not to spread and that deprives your tree of needed nutrients.
When preparing the hole for your tree, follow the steps as described in the article linked below to give the roots room to spread and to prevent the graft site from sinking below soil level. Backfill with native soil. As you can see from the diagram below, most of the root ball should be above the original soil level to avoid crown rot. The tree will also settle.
And unless you want a huge tree with more fruit than most families could possibly eat, prune the trunk back to about knee height after planting. This takes some courage, but your tree will reward you with plenty of fruit that is easy to reach. Wait until the weather will be dry for at least several weeks to prune apricots, apriums, and cherries.
Other considerations are pollination requirements, ultimate tree size, chill hours, and disease susceptibility. Pollination is necessary for good fruit production. Some fruit trees have flowers with both male (anthers) and female (pistils) organs and can self-pollinate, such as persimmons and Bartlett pears. Other trees have flowers with both male and female organs but cannot self-pollinate and will require a second tree planted within 100 feet for fruit production, such as many apple varieties and Asian pears. Still others have separate male and female flowers.
Deciduous fruit and nut trees require a certain number of “chill hours” below 45°F to produce. It is important to select only varieties that have chill hour requirements equal to or lesser than the chill hours listed for your area. This reference discusses chill hours and has links to fruit tree requirements for Contra Costa County: https://ccmg.ucanr.edu/files/77176.pdf
It's important to know which diseases and pests a particular fruit tree is susceptible to. For example, apricots and their crosses such as aprium and pluot are prone to infection by the Eutypa fungus and unlike most deciduous trees, should be pruned in late summer before the weather gets damp. Check the reference below. These references have links and information regarding fertilization, pollination, pests and diseases, and characteristics of various fruit trees.
Despite our recent rains, we are still in a drought. Most fruit trees need substantial amounts of water to become established and as they mature and produce fruit.

If you missed our planting and pruning Bare Root Fruit Trees Class, you can watch the recording on our UCCE Stanislaus County Master Gardener YouTube Channel. The class includes information on deciduous fruit trees, including apple, pear, cherry, nectarine, peach, plum, and apricot.
What about Citrus?
Citrus trees such as oranges, lemons, grapefruits and kumquats are evergreen trees and need different care than deciduous trees. Our program will offer an online class on March 22 on Caring for Citrus. Registration coming in early March 2022.

Deciduous Fruit Trees
Deciduous fruit trees lose their leaves each winter. These trees include apple, pear, cherry, nectarine, peach, plum, and apricot; it does not include citrus or avocado trees, which are evergreen.
What is a Bare Root Fruit Tree?
A “bare root” fruit tree is a tree sold in its dormant state. The tree has no leaves, is not actively growing, and is sold without a pot. When you choose your tree, a store employee pulls it out of a large container with other trees that is filled with sawdust. The tree roots are wrapped with moistened newspaper, and then covered over with butcher paper and tied with a string. You'll be advised to take it home and plant it right away. Some garden centers may sell bare root fruit trees in plastic bags. If the material around the roots is moist and the roots have not dried out, the tree should be healthy.
Choosing a Fruit Tree
I have a Small Yard or an Apartment, Can I have a Fruit Tree?
Deciduous fruit trees as well as evergreen fruit trees get very large. Fruit trees grafted onto dwarfing rootstock and labeled “genetic dwarf” are smaller than semi-dwarf and standard trees, however they have extensive roots and are not recommended for containers. One exception is the kumquat, a sweet and tangy citrus fruit. Small yards can have fruit trees, but you have to start your tree out right for this to work.
If you live in an apartment and want fruit, you can grow your own blueberries or strawberries in containers. See our publications:

For gardeners the coming of winter means, among many other things, the beginning of the bare root planting season. Local nurseries will soon receive good supplies of bare root fruit and ornamental trees, roses, grapes, berries, and vegetables such as asparagus and rhubarb. Unlike container plants, bare root plants are dug from the field when dormant and separated from the soil. This allows the nursery grower to ship plants at a lower cost and means a good saving for the buyer.
Since all the soil has been removed from the roots, take care to prevent them from drying out while you transport the tree or dig the planting hole. Never allow the plant roots to be exposed to sun and wind for more than just a few minutes. You can protect the roots for a few hours by placing them in a moist plastic bag or by covering them with wet newspaper or cloth. It's best to plant and water your bare root trees right away. If you need to delay planting for a day or more, you should “heel in” the plants. “Heeling in” is a method of protecting plant roots by placing the plants into a hole or shallow trench and covering the roots with moist soil, sand or sawdust.
You should consider trees, shrubs and other perennial plants to be long term investments. It's therefore worth the effort to pick the proper place for the plant. Fruit trees especially need full sun to produce properly, as well as room to grow. Most standard fruit trees can be planted 10 to 15 feet apart, or much closer if you are willing to spend time doing heavy pruning and careful training each year. Semi-dwarf fruit trees are good choices for a garden with limited space. It is not a good idea to plant a fruit tree in a lawn area, as the lawn's water requirements are not compatible with those of the tree. Fruit trees growing in lawns often grow poorly or are killed by shallow, frequent lawn irrigation.
Fruit trees prefer well drained soils at least 3 or 4 feet deep but will grow in shallower soils if you water carefully. Plant your tree when the soil is moist enough to dig easily. Do not plant in wet, sticky soil. The planting hole should be 2 to 3 times wider than the root spread, but only deep enough to plant the tree at the same level as it grew in the nursery. A tree planted in a deep hole will settle too much after watering. When this happens the tree is often attacked by a soil borne fungus disease where the soil contacts the trunk.
Before you plant the tree, carefully cut off broken or badly damaged roots with sharp pruning shears. Do not prune the roots to fit the hole. If necessary, put soil in the bottom of the hole so that the tree is slightly higher than the soil line. This will allow the tree to settle slightly without becoming buried. Using the same soil that came out of the hole, carefully cover the roots completely, then water thoroughly to settle the soil around the roots. You may want to complete the planting job by placing a mulch on the ground around the tree to help control weeds and conserve moisture.
