Now growing and available now until sold — flower buds now developing.

This tree was grafted in 2022, and has a more developed and established root system than its 2023 counterparts. It flowered and fruited last year and will do so again this 2024/2025 season.

In a 25 litre black poly planter bag of 300 mm diameter.
Height is about 600 mm including bag.
These trees always look bottom-heavy, off-centre and over-potted in these bags, as this is the way they grow. A tall slender trunk with a mass of thick, sprawling roots is very typical for this age.
If I potted this tree into a bag more matched in size to the trunk I would have to trim at least 50% of the roots.
The shape and sprawl of the roots is the only reason this tree is off-centre in the bags.

Now that this tree is flowering I strongly recommend leaving it in the bag until next winter when it becomes dormant. There is a risk of transplant shock from root disturbance otherwise.

Take advantage of this — being in a bag makes them mobile and gives you time to determine the best final position for your tree!

If you are planting into the ground, prepare your hole now. Dig a hole at least 500 mm diameter and 500 mm diameter deep. Mix this soil with plenty of organic matter (compost), refill the hole, and pile the excess soil in a mound on top. The mound will slowly sink with time as the organic matter breaks down and everything settles. Repeat every few months, and you will have an open, rich planting medium ready for your tree.

Your tree is ready to plant next winter, when it has shed all its leaves and is well and truly dormant.

Leave the tree in the bag as a guide as to how deep to dig your hole or how deep to add a good quality potting mix to your permanent pot. Position the tree in place, still in the bag, then cut the plastic away gently down the sides and slide out from under the root ball. Back fill and water in deeply.

Description of Fruit:
Lang is a large pear-shaped fruit similar to Ta-Jan.
Mid to late-season ripening.
Fairly good for fresh eating if fully red/brown, but is best dried. Very good for processing.

Description of Tree:
(The following information is from The Biosphere Blog on our sister site The Jujube Tree Nursery. More information can be found here and here.)

The jujube tree is deciduous. It can grow to 10 m high by 6 m wide, but keeping pruned to a height of 3–5 m makes management and harvesting easier.
It is native to climates with a yearly temperature range from around -5°C to 50°C, but can survive winters that get down to -30°C.

While growth in areas with cool summers can be very slow, the tree thrives in hot, dry environments with long summers and warm nights. Heat is crucial for flower production and fruit development, and jujubes require a range of at least 20°C to 25°C during the flowering stage for fruit to set. Unlike most fruit trees, jujubes have a very long period of flowering, often over a few months. If temperatures are too cool for the first flush of flowers to set fruit, later flowers usually will as the weather warms.

While summers can’t be hot enough, the tree does need around 200-400 hours of exposure to temperatures below 7°C over winter during dormancy. This is called its chilling requirement, and ensures vernalisation (the induction of the flowering process) occurs in spring.

Jujube trees flower later than other fruit trees, from November on, and are thus unaffected by late frosts that can devastate other fruit crops.

They can grow in a range of soils from acid to alkaline, but prefer deep and well-drained soils.

The rootstock will sucker, but easily kept under control with secateurs or even a lawn mower.
