Detailed Explanation of the Care Methods and Techniques for Juniperus chinensis 'Kaizuca' Bonsai

Placement:

Juniperus chinensis 'Kaizuca' is best placed in a spot with good air circulation and ample sunlight. It is cold-tolerant in winter and can generally be overwintered outdoors; simply place the pot in a sunny, wind-sheltered spot. During the high-temperature period of midsummer, except for small bonsai, shading is generally not needed.

Watering:

Juniperus chinensis 'Kaizuca' is drought-tolerant and afraid of waterlogging, so watering should not be on the wet side; the principle of "dry-wet cycle" must be followed, and it should not be watered when not dry. During the plum rain season, make sure water does not accumulate in the pot; in summer, water in the morning and evening; in winter, simply keep the potting soil moist.

Fertilizing:

It is not demanding about fertilizer. Applying diluted, fully decomposed cake fertilizer water or organic fertilizer 2 to 3 times each year from March to May in spring, and 1 to 2 times in autumn, will result in dense branches and leaves and healthy growth.

Pruning:

Juniperus chinensis 'Kaizuca' is generally pinched back as the main method; for leggy side branches, the tips can be cut off to encourage the growth of side branches. When early summer brings the vigorous growth period, pinching and tipping should be done in time to keep the crown dense and the form beautiful. For large branches that affect the tree's shape, pruning is best done during the dormant period.

Repotting:

Juniperus chinensis 'Kaizuca' bonsai grows slowly and can be repotted once every 3 to 4 years, with spring from March to April being the best time. When repotting, some old roots can be appropriately cut away, 1B2 of the old soil removed, and replaced with fertile, loose potting soil to promote the growth and development of new roots. Also note that the bottom of the pot should be lined with tile pieces and a layer of coarse sand to aid drainage. This is especially true for cascade-style bonsai, which use tall cylindrical pots; the bottom of the pot must be lined with 1B3 of broken tile pieces and coarse sand so that water does not accumulate, which benefits growth.

Pest and Disease Control:

The main disease of Juniperus chinensis 'Kaizuca' is rust, which can be controlled by spraying 1% Bordeaux mixture or 3% lime water; the main pest is red spider mite, which can be treated by spraying 80% dichlorvos at 1500 times dilution.

The focus should be placed on wiring and shaping the trunk and large branches. The wiring should not be too tight, to facilitate branch and trunk growth. Small branches can be appropriately pruned and shaped. Shaping is best carried out from March to April.

The terminal buds of the branches of Juniperus chinensis 'Kaizuca' grow relatively quickly; if left unchecked and allowed to grow wildly, this greatly affects its ornamental value and also affects the balanced growth of the side buds; after the terminal buds are removed, the leaves of the other branches will also grow more and more neatly and densely.

Light
