What are the cultivation methods and precautions for tamarisk bonsai?

Tamarisk is a shrub flower whose blooms resemble those of knotweed, with very high ornamental value, and its flowering period is also very long. In addition, tamarisk's economic value is very high as well; it can be made into many items, can be used as excellent livestock feed, and can also serve as a honey-source plant, and so on. Tamarisk is also very suitable as a bonsai. Below, let us learn about its cultivation methods together.

How to grow tamarisk bonsai

1. Potting soil. Tamarisk is tolerant of saline-alkali soil by nature and prefers moisture, so the potting soil should preferably be neutral or slightly saline-alkaline, breathable, loose, sandy soil. Repot, trim the roots, and replace the soil with new soil once a year. The new soil should mainly consist of leaf mold and honeycomb briquette cinders, with a suitable amount of fertilizer and lime residue added.

2. Fertilizing. Tamarisk has a well-developed root system and likes nitrogen fertilizer. Normally, apply a light alum fertilizer solution once every half month, adopting the method of frequent light applications. During vigorous growth, apply frequently and appropriately more; when growth is poor, apply slowly and less. Before leaf drop in late autumn, apply monopotassium phosphate once to promote the aging of branches and the storage of nutrients, and to prevent branch shrinkage in winter.

3. Watering. Although tamarisk is drought-tolerant, it prefers moisture. The potting soil should rather be wet than dry, and the potting soil should be kept constantly moist.

4. Light. Tamarisk is a strongly heliophilous tree species and is not shade-tolerant. It should be placed in a ventilated spot with ample sunlight, but during the dog days when the sunlight is too strong, it may be slightly shaded.

5. Pruning. Although tamarisk is tolerant of pruning, improper pruning timing can easily cause branch shrinkage and dead branches. Pruning should be carried out in spring and summer. If pruned in autumn, the new growth will not age and store enough nutrients, causing branches to shrink and die after overwintering. Do not prune in winter; wait until buds emerge in spring before pruning, cutting away dead branches, surplus branches, and weak thin branches to maintain tree vigor. In addition, after each flowering, the spent flowers should be cut off promptly.

Tamarisk bonsai cultivation methods and precautions

I. Cultivation methods

1. Site: In hot summer, it should be placed in a semi-shaded spot or a shade net should be set up over the cultivation area. In northern regions, in late autumn and early winter, potted tamarisk should be moved into a low-temperature indoor space, or the pot should be buried in a wind-sheltered, sunny spot with soil mounded around the trunk, which can also allow it to overwinter outdoors. In the south, place it in a wind-sheltered, sunny spot in winter, and it can overwinter outdoors.

2. Watering: Although tamarisk is drought-tolerant, it prefers moist soil even more. Normally keep the potting soil damp, but water must not accumulate in the pot. In hot summer, besides watering the pot, also sprinkle water on the ground. In winter, water less, but also keep the potting soil moist. During the growing season, dry potting soil often causes yellow leaves and withered branch tips, and in severe cases causes the entire tamarisk to die.

3. Fertilizing: For tamarisk already potted in an ornamental pot, apply decomposed organic liquid fertilizer once a month. Excessive fertility can cause leggy branches and ruin the tree's shape. Do not fertilize during the plum rain season and in winter.

4. Shaping: Tamarisk has strong sprouting ability and grows fast. During the vigorous growth periods of spring and summer, prune once a week to maintain the tree shape. As for new buds sprouting on the trunk, any that are not needed for the design should be removed promptly to avoid consuming nutrients. To improve the ornamental quality of tamarisk, you can take advantage of its strong sprouting ability by removing all the leaves during the vigorous growth period, then placing it in a spot with ample sunlight, strengthening fertilizer and water management, and spraying water on the branches and trunk once each in the morning and evening. In 5 to 6 days new buds can sprout, and in 20 days the leaves will be as full as before, tender green and lovely.

II. Precautions

1. Repotting: Tamarisk grows relatively fast. Generally, bonsai should be repotted once every 1 to 2 years, and old-stump bonsai once every 2 to 3 years. Repotting should be done in February to March each spring before tamarisk buds. During repotting, cut off dead roots and appropriately remove some overly dense roots; removing too many fibrous roots at once can cause branches to die. Tamarisk in vigorous growth should be moved to a pot one size larger, while old stumps can remain in the original pot. Replenish the pot with new, fertile culture soil.

2. Pest and disease control: Tamarisk has relatively few pests and diseases, with occasional aphid outbreaks. It can be killed by spraying with 40% omethoate emulsifiable concentrate at 1500 times dilution. If the pest infestation is severe, spray again with omethoate after 7 to 10 days.

Making a weeping willow-style tamarisk bonsai

1. Branch and trunk cultivation

To create a weeping willow-style tamarisk bonsai, the first thing is to cultivate the trunk. Choose a tamarisk, cut off all its original shaping, then leave one strong bud on the main trunk. When it grows to the semi-lignified stage, use wire to shape it, and be careful not to pinch off the growing tip. After about 20 days it can be removed, and all the remaining branches and buds should be removed. In this way, after autumn it can basically take shape, and in winter it can be cut back.

2. Cultivating drooping branches

In spring, cultivate drooping branches on the tamarisk. According to the shape you want, keep 4-5 strong buds on the main trunk and remove all the other branches and buds. When the branches grow to the semi-lignified stage, use wire to shape them. After removing the wire 20 days later, let them grow freely until July. At this point, you can keep some strong branches and let them grow; you must also wait until they are semi-lignified to shape them. In this way, you can cultivate the branch supports for drooping branches.

Introduction to tamarisk

1. Other names

Tamarisk is also called red willow, branched tamarisk, weeping silk willow, West River willow, West Lake willow, and shade willow.

2. Growth habits

Tamarisk does not have high requirements for soil; both sandy and clay soils suit it. Tamarisk is also a relatively drought-tolerant and heat-tolerant plant, with a high ability to adapt to desert climates and high-temperature climates. It relatively likes light and is not very shade-tolerant.

3. Uses

Tamarisk blooms beautifully and has a very long flowering period, with good ornamental value, and it is also a very good honey-source plant.

In addition, tamarisk's economic value is also very high. Its branches can be made into many things, including baskets. Its leaves are also very good livestock feed.

Tamarisk is a plant that combines ornamental value and economic value, and is very suitable for growing as a potted plant at home. It does not have high requirements for soil and has very strong adaptability. However, one point to note is that it is a plant that relatively likes light, so it should be sunned often.
