Bare-root fruit trees are dormant, leafless trees sold with no soil around their roots, and in San Diego County the best time to buy them is December and January, when nursery selection is at its peak. Planting them in winter gives the roots time to settle into your soil before spring growth begins.
This guide explains what bare root means, how chill hours decide which varieties will actually fruit in San Diego, and seven steps to plant a tree correctly. It's written for home gardeners planning an edible yard this winter.
Key takeaways
Timing matters. Nurseries stock bare-root trees from about December through early March, and UC Master Gardeners say December and January offer the best supply and choice.
Chill hours decide the variety. San Diego winters are mild, so choose low-chill varieties. San Diego County Master Gardeners point to fruit needing 0 to 300 chill hours as the safest picks for most of the county.
Bare root costs less and roots in faster. The roots grow straight into your native soil instead of transitioning from potting mix.
Never let the roots dry out. Keep them covered and moist, and soak them for one to two hours before planting.
Don't plant too deep. It's one of the most common and most damaging mistakes.
Be patient. Expect your first real harvest in two to three years.
What are bare-root fruit trees?
A bare-root tree is a young tree dug up from the nursery field while it's dormant and sold without soil. Because it has no leaves and is resting, it handles the move well. Once planted, the roots wake up, take in water and nutrients, and push out the burst of growth you see in spring.
Bare root applies to dormant, deciduous plants such as peaches, plums, apricots, pears, low-chill apples, and persimmons. Evergreen trees like citrus don't go dormant, so you'll find them in pots instead.
Why plant bare root in San Diego?
San Diego's mild climate means you can plant potted trees almost any time of year, so why bother with bare root? There are three good reasons:
Better selection. Bare-root season is when nurseries carry the widest range of deciduous varieties. The potted trees you find later are often what didn't sell.
Lower cost and easier handling. Without the pot and soil, a bare-root tree is lighter, easier to carry home, and usually cheaper.
Healthier roots. Bare-root roots haven't spent years circling in a container, and they grow directly into your garden soil.
Bare root vs. potted: which should you choose?
Timing. Bare root: winter, while the tree is dormant. Potted: almost any time of year.
Cost. Bare root: usually lower. Potted: usually higher.
Selection. Bare root: the widest choice of deciduous varieties in December and January. Potted: whatever is left in stock, plus evergreens like citrus.
Root system. Bare root: roots spread directly into native soil. Potted: roots may need help if they've circled in the container.
Urgency. Bare root: plant promptly, before roots dry out. Potted: more forgiving if you wait a few days.
How to choose the right variety: chill hours
Chill hours are the number of hours each winter that temperatures stay below 45°F. Many fruit trees need a certain amount of cold to break dormancy and set fruit. In most parts of San Diego County there aren't many nights that cold, so a variety that needs 800 or 1,000 chill hours will leaf out weakly and fruit poorly.
The fix is choosing low-chill varieties. UC guidance generally treats low-chill apples, apricots, pears, peaches, and plums as those needing about 300 hours or fewer. San Diego's Master Gardeners recommend sticking to that 0 to 300 hour group for most of the county. A few things to keep in mind:
Check your microclimate. Coastal neighborhoods get fewer cold hours than inland valleys. Ask the nursery staff what they've seen work near you.
Look for proven low-chill apples. UC guidance names 'Anna' and 'Dorsett Golden' among the apples for warm-winter areas. San Diego garden writer Nan Sterman has also recommended Pink Lady and Sundowner.
Consider a multi-grafted tree. If space is tight, one tree with several low-chill varieties on a single rootstock gives you a longer harvest in a small footprint.
Ask a local expert. The UC Master Gardeners of San Diego County hotline and the California Rare Fruit Growers San Diego Chapter can help with varieties for your exact area.
7 steps to plant a bare-root fruit tree
1. Choose your site before you buy
Pick a spot with at least six to eight hours of sun and well-drained soil. If the soil is compacted, loosen a wide area so the roots can spread. Knowing where the tree goes first means you can plant it the day you bring it home.
2. Inspect the roots at the nursery
Look for a tree with fibrous, well-developed roots spread evenly around an undamaged central root. Avoid trees with dried, shriveled, or mushy roots.
3. Keep the roots moist until planting
Plant as soon as you can. If you can't, "heel in" the tree by laying the roots in a shallow trench and covering them with moist soil, compost, or sawdust.
4. Soak the roots, then trim any damage
Soak the roots in a bucket of cool water for one to two hours before planting. Trim off any broken or decayed roots with clean pruning shears.
5. Dig a wide hole, not a deep one
Make the hole about two to three times as wide as the root spread, and no deeper than the roots need. Spread the roots out naturally. Don't curl them around the hole to make them fit.
6. Set the tree at the right depth and backfill
Hold the tree upright, cover the roots with an inch or two of soil, and water to settle it. Finish filling to the surface and water again. Planting too deep is the mistake to avoid, so check the level before you fill the last of the hole. Don't plant into saturated soil.
7. Build a basin and keep watering
Form a shallow basin and water a few inches out from the trunk to encourage roots to reach outward. UC Master Gardeners of Orange County suggest filling the basin once or twice a week in hot weather and less often when it's cool or rainy. Mulch around the tree, keeping it a few inches off the trunk.
Common bare-root mistakes
Buying before choosing the site. A tree sitting out for weeks is a tree losing its roots' moisture.
Picking a high-chill variety. It may leaf out, but it won't fruit well in a mild-winter yard.
Letting the roots dry out. Even a short time in sun and wind can damage fine roots.
Planting too deep. Buried trunks can stress or rot the tree.
Planting into soggy ground. Wait for the soil to drain.
Expecting fruit in year one. Most young trees need two to three years to settle in.
Frequently asked questions
When are bare-root fruit trees available in San Diego?
Nurseries typically carry them from about December through early March, with the best selection in December and January. San Diego County Master Gardeners suggest buying deciduous plants bare root in January.
Can I plant citrus or avocado bare root?
No. Bare root is for dormant, deciduous plants. Evergreens like citrus and avocado are sold in containers and can be planted at almost any time of year in San Diego.
What if I can't plant right away?
Heel the tree in by covering the roots with moist soil or sawdust, and keep them from drying out. Plant as soon as you can.
How long until I get fruit?
Plan on two to three years before a young tree really starts to produce.
How many chill hours do I need?
It depends on your microclimate, but for most of San Diego County, varieties rated at 300 hours or fewer are the safest. A local nursery or the Master Gardener hotline can help you narrow it down.
Where to start
This week, walk your yard and pick the sunniest, best-drained spot for your first tree. In early December, call a local nursery and ask when bare-root stock arrives and which varieties they carry for low-chill climates.
