Potted jujube trees can bloom in the same year, and some can even bear fruit, with small leaves and red fruit. Jujube trees can be potted in open ground with good light conditions, courtyards, building balconies, and other places. Here we introduce the cultivation methods for potted jujube trees for reference.
1. Pots and nutrient soil: For potted jujube trees, clay pots, ceramic pots, plastic pots, etc. can be used. For the nutrient soil, use 1/2 compost soil made from legume crop straw plus 1/2 garden soil, add a small amount of sand, and for each cubic meter of nutrient soil, add 1 kg of 25% nitrogen-phosphorus-potassium compound fertilizer and mix well.
2. Planting: Choose varieties with well-developed root systems and plant during the dormant period of the jujube tree. Place a few pieces of broken tile over the drainage hole of the pot, put a small amount of sand at the bottom of the pot, and then add part of the nutrient soil. Spread the root system of the jujube tree in the pot, add nutrient soil while patting the side of the pot, and finally press gently and water thoroughly once. After some time, when the soil in the pot settles, add more nutrient soil, leaving a few centimeters of depth at the pot rim unfilled as a watering opening.
3. Fertilizer and water management: Potted jujube trees generally begin to bloom in June, when the plant has relatively high humidity requirements. On sunny days, water every day to keep the potting soil moist. In spring and autumn, on sunny days, water once every 1 to 2 days. In winter, when the potting soil is dry, water with antifreeze water.
Potted jujube trees are mainly given organic fertilizer liquid such as cake fertilizer, applied once every 7 to 10 days. The branch and leaf growth period, flower bud development period, and young fruit growth period of the jujube tree are all major periods of nutritional demand. At these times, apply organic fertilizer liquid 2 times, then apply 0.3% urea solution once to supplement the tree's demand for mineral nutrients. In autumn during the fruiting period, phosphorus fertilizer application should be increased, applying 0.2% monopotassium phosphate solution 2 times.
4. Flower and fruit management
(1) Preserving flowers and fruit: Girdling during the flowering period can increase the fruit-setting rate. When the flowering amount of the jujube tree reaches 30% to 40%, perform girdling at the base of the main trunk, generally with a cut width of 0.2 cm. Jujube trees like light, and potted jujube trees should be placed in a location with good ventilation and light transmission to facilitate fruit setting. Spraying 10 ppm to 15 ppm gibberellin plus 0.3% urea solution during the flowering period can increase the fruit-setting rate. Spraying 0.3% monopotassium phosphate solution 2 times during the fruit enlargement period can increase the fruit-setting rate. When about 3 jujube bends appear on the jujube head of non-skeletal branches, pinching the jujube head can also increase the fruit-setting rate.
(2) Fruit thinning: When potted jujube trees have too much fruit or uneven fruit setting density, fruit thinning should be carried out, removing poor-quality and smaller fruits from overly dense areas. Fruits grown from late flowers are not easy to mature. If there are many fruits developed from early flowers, and late fruits hinder the growth of early fruits, the late fruits should be thinned out.
5. Pruning: For shaping potted jujube trees, the trunk form can be used for pruning. The trunk height is 20 to 30 cm, with about 5 main branches growing on the central leader, and branch groups growing on the main branches. Potted jujube trees should be pruned in February to March, removing useless branches, crossing branches, overly dense branches, etc. For skeletal branches that need to be extended, the jujube head should be cut back, and the first secondary branch below the cut must be removed, otherwise the main bud will not sprout. Branches to be used for fruiting should be cut back to the 2-year-old part, and the secondary branch below the cut should not be removed.
6. Pest and disease control: The main pests and diseases of potted jujube trees include jujube moth, tortoise wax scale insect, jujube leaf roller, jujube geometrid, jujube witches' broom, etc. Jujube moth, jujube leaf roller, and jujube geometrid can be controlled by spraying 3000-fold decis solution during the larval stage. Tortoise wax scale insects can be scraped off during the dormant period of the jujube tree, or controlled by spraying 50% dichlorvos 800-fold solution during the nymph stage. Using natural enemies such as ladybugs and mantises to prey on pests also works very well. Potted jujube trees affected by jujube witches' broom should be promptly pulled out of the pot and buried deep.
7. Repotting or changing nutrient soil: Potted jujube trees should be moved to a larger pot after growing in the pot for 2 to 3 years. During the dormant period, pull the jujube tree out of the pot, remove the root pad and a small amount of roots, then put it back into the pot with soil and add nutrient soil. For potted jujube trees that are not moved to a larger pot, the nutrient soil should also be changed about every 2 years of planting to benefit the growth of the jujube tree. After pulling out the jujube tree, remove the root pad and a small amount of roots, add nutrient soil, then put the original jujube tree back into the pot with soil, fill with enough nutrient soil, and water thoroughly.
8. Overwintering: Placing potted jujube trees indoors or in a shed allows them to overwinter safely. In areas where winter is not too cold, they can also overwinter outdoors. Cover the pot with some grass, check whether the potting soil is dry before a cold wave arrives, and if the potting soil is dry, water thoroughly once to help the potted jujube tree overwinter safely.
