Jujube Tree Care Guide
The 4,000-year-old fruit tree that asks almost nothing of you. Rock Sugar Crispy Jujube produces super-sweet, crunchy fruit with the texture of a crisp apple. Tolerates drought, poor soil, extreme heat, and subzero winters — the closest thing to a plant-it-and-forget-it fruit tree. Ships 20–28 in tall in nursery grow bag.
Year-round care calendar
- Still dormant — jujube is one of the LAST trees to leaf out (May is normal!)
- Do not panic and think it is dead — scratch bark for green tissue
- Apply balanced 10-10-10 fertilizer lightly
- Probably still dormant — other trees are green, jujube sleeps in
- Remove suckers that appeared over winter
- Begin weekly watering if spring is dry
- FINALLY leafing out — glossy green leaves appear, often not until late May
- Flowers appear on new growth shortly after leaves
- Increase water slightly during flowering
- Fruit set — small green fruit begins developing
- Deep water every 2–3 weeks — overwatering is more dangerous than underwatering
- Jujube flowers on current year's growth — this is why you can prune in winter without losing fruit
- Fruit developing — green, olive-sized
- Water deeply but infrequently — established trees need almost no supplemental water
- Remove root suckers — jujube suckers aggressively
- Fruit begins ripening — green → brownish-red
- Taste-test: harvest at half-green/half-brown for crispy apple texture
- Reduce water to concentrate fruit sugars
- Peak harvest — fruit at crispy stage (fresh eating) or let fully brown and wrinkle for date-like sweetness
- Harvest every few days — fruit ripens sequentially
- Leaves turn yellow — normal fall color, not a problem
- Harvest continues — last fruit of the season
- Leaves drop — tree enters dormancy
- Stop all fertilizer — tree must harden off for winter
- Dormant — bare branches are normal
- Water deeply once before ground freezes
- Young trees (first 2 winters): wrap trunk or mound soil for insulation
- Fully dormant — survives -28°F once hardened off
- No water needed — winter precipitation is sufficient
- No fertilizer
- Dormant — the most cold-hardy fruit tree on this site
- Remove any remaining suckers at ground level
- Plan winter pruning for February
- Winter prune — select 3–4 scaffold branches, thin interior for light
- Jujube fruits on new growth — pruning does NOT reduce the crop
- Prepare for late spring emergence — remember this tree is fashionably late
Care at a glance
How to plant your Jujube Tree
Pick the sunniest spot you have
Jujube demands full sun — at least 6 hours of direct sun per day. This tree evolved in the arid regions of China and thrives in heat. It tolerates reflected heat from walls and pavement better than almost any fruit tree. Not enough sun = sparse fruit. For maximum production, plant where it gets morning through late afternoon sun.
6+ hours direct sun, tolerates reflected heat
Soil — this tree is not picky, but drainage helps
Jujube tolerates almost any soil: sand, loam, clay, alkaline (pH up to 8.0), and even moderately saline soils. This is one of the most soil-adaptable fruit trees in existence. The one requirement: drainage. Standing water will kill it. In heavy clay, plant on a raised mound. Dig a hole twice as wide as the pot and the same depth.
Tolerates almost any soil — just drain it
Plant, water in, and mulch
Plant with the root crown at or slightly above soil level. Backfill with native soil — no amendments needed. Water deeply with 5 gallons. Apply 2–3 inches of mulch, keeping it away from the trunk. Jujube is partially self-fertile but produces significantly more fruit with a second variety nearby for cross-pollination. Two different varieties within 50 feet = best production.
5 gallons, mulch, cross-pollination helps
Ongoing care: the easiest fruit tree you will ever grow
Spring (March–May)
Water: Deep watering every 2–3 weeks during the first year. Jujube is extremely drought-tolerant once established. Overwatering is far more dangerous than underwatering.
Fertilize: Lightly. Apply balanced fertilizer (10-10-10) once in early spring — only if the tree shows weak growth (less than 2 feet of new growth). In fertile soil, jujube needs NO fertilizer.
This season: Jujube leafs out LATE — often not until May. Do not panic when every other tree greens up and your jujube still looks dead. This is normal. New growth emerges with thorns (wild-type characteristic). Expect 12–24 inches of new growth. Flowers appear in late spring — small, yellow, star-shaped, and fragrant. Jujube blooms on new wood, so winter pruning won’t remove fruiting wood.
Summer (June–August)
Water: Minimal. Mature trees: supplemental water only during prolonged drought (3+ weeks without rain). Young trees: deep watering every 2–3 weeks.
Fertilize: None — unless the tree shows obvious deficiency (pale leaves, weak growth). Jujube is not a heavy feeder.
This season: This is when the magic happens. Jujube loves heat — the hotter the summer, the heavier the crop. Fruit develops through July–August, ripening from green to brown. Fruit is crisp and apple-like when half-ripe, becoming date-like and chewy when fully ripe. Birds love jujube — netting may be necessary. Thorns are sharp; wear gloves when harvesting.
Fall (September–November)
Water: Reduce. Stop watering entirely a few weeks before the first frost to help the tree harden off.
Fertilize: None.
This season: Harvest continues through October. Fruit is ready when fully brown and slightly wrinkled (for date-like sweetness) or green-brown and crisp (for apple-like texture). Leaves turn yellow and drop — this is normal deciduous behavior. Allow fallen leaves to remain as mulch. After leaf drop, the tree’s architectural branch structure is revealed — jujube has a distinctive zigzag branch pattern.
Winter (December–February)
Water: NONE during dormancy. The leafless tree uses almost zero water. Watering a dormant jujube causes root rot.
Fertilize: None.
This season: Jujube is fully dormant and leafless — this is normal and required for fruit production (chill hours). Hardy to Zone 6 — mature trees survive -20°F with no protection. This is the pruning season: remove dead, crossing, or inward-growing branches. Jujube can be pruned hard — it regenerates vigorously. Do NOT water. The tree needs nothing from you now. Resume deep watering when new growth appears in late spring.
Pruning: simple, but timing matters
When: Late winter (February–March) while the tree is fully dormant. Jujube flowers and fruits on new growth from the current season, so winter pruning does not reduce the crop.
Young trees (years 1–3): Select 3–4 well-spaced scaffold branches to form the permanent structure. Remove the central leader at 3–4 feet to encourage an open vase shape. Jujube naturally has a somewhat irregular, zigzag branching pattern — work with it, not against it.
Mature trees: Thin out crowded interior branches for light and airflow. Remove suckers (jujube suckers aggressively from roots — remove them or you will have a thicket). Remove dead, diseased, or crossing branches. Jujube can be kept at 10–15 feet with annual pruning for easy harvest.
Unique characteristic: Jujube branches have a natural zigzag growth pattern with small thorns at the nodes. The thorns are not severe but wear gloves. The zigzag form means the tree looks “twiggy” in winter — this is normal, not a problem.
DON’T: Prune in spring after bud break (removes fruiting wood). Let suckers take over the yard. Over-prune — jujube needs less pruning than almost any other fruit tree.

Harvesting: two fruits in one
When: Late August through October, depending on variety and climate.
Two harvest stages — same fruit, completely different experience:
1. Crispy stage (half green, half brown): Pick when the fruit is still firm, with green skin beginning to show brown patches. Texture is crisp and apple-like. Flavor is mildly sweet, refreshing, similar to a crisp Asian pear. Eat fresh, slice into salads, or pickle. This is how jujubes are traditionally eaten fresh in China.
2. Date stage (fully brown, wrinkled): Let fruit fully ripen and partially dry on the tree. Skin turns completely brown and wrinkles. Texture is chewy and date-like. Flavor is intensely sweet with caramel notes. Use in baking, trail mix, or eat as a natural candy. The sugar content concentrates as the fruit dries.
How to pick: Hand-pick or shake branches over a tarp. Ripe fruit detaches easily. Harvest every few days during peak season — fruit ripens sequentially over several weeks. Fresh jujubes store 2–3 weeks in the refrigerator. Dried jujubes store for months at room temperature.
Frequently asked questions
What does jujube fruit taste like?
Depends on when you eat it. Picked early (half green, half brown): crisp, mildly sweet, like a cross between an apple and an Asian pear. Left to fully ripen and wrinkle on the tree: chewy, intensely sweet, like a date with caramel notes. You get two completely different fruits from the same tree. Most growers harvest some at each stage.
Is jujube really hardy to -28°F?
Yes — once fully dormant. Jujube is one of the most cold-hardy fruit trees available, surviving temperatures that would kill peaches, plums, and certainly citrus. The key word is “dormant” — the tree needs time to harden off in fall. Late-season fertilizing or watering can delay dormancy and reduce cold tolerance. Young trees (first 2 winters) benefit from trunk protection — wrap with tree wrap or mound soil around the base.
Why is my jujube not leafing out when everything else is green?
Jujube is famous for being the last tree to wake up. In Zone 5–6, it may not leaf out until late May or even early June. This is a survival adaptation — by staying dormant through late spring frosts, jujube avoids the freeze damage that devastates peaches and other early-leafing trees. Every spring, gardeners panic and think their jujube died over winter. Scratch the bark — if it is green underneath, it is alive and just fashionably late.
Do I need two jujube trees?
Jujube is partially self-fertile — one tree will produce some fruit. But you will get significantly more fruit with two different varieties for cross-pollination. The flowers are small and attract bees and flies. Two varieties within 50 feet = maximum production. If you only have room for one tree, you will still get fruit — just less of it.
How do I deal with all the suckers?
Jujube suckers aggressively — it is the tree’s natural propagation strategy. Management: mow suckers that appear in lawn areas (they will not survive regular mowing). In mulched or gardened areas, cut suckers at or below soil level with sharp pruners. Persistent suckers can be painted with a small amount of glyphosate (carefully — do not get it on the main tree). Avoid tilling or cultivating near the tree — root disturbance triggers more suckering. Some growers embrace the suckers and dig them up to share as free trees.
Is jujube invasive?
Jujube (Ziziphus jujuba) is considered invasive in some parts of the southeastern US. It spreads by root suckers and seeds (birds and mammals eat the fruit and disperse seeds). Check your state’s invasive species list before planting. In non-invasive regions, manage suckers to keep the tree contained. Do not plant near natural areas where it could escape.
