How to Plant a Cedar? Detailed Guide to Planting Methods and Precautions

The cedar (Cedrus deodara) is an evergreen arbor plant, tall and upright, very majestic, with high ornamental value. It holds a very high status in landscaping, and it also represents a spirit of unwavering integrity, deeply loved by flower enthusiasts. For flower enthusiasts, growing a cedar is also a kind of spiritual release. So what exactly is the planting method for cedars?

How to Plant a Cedar

1. Soil

It has no strict requirements for soil and can adapt to both acidic and slightly alkaline soil. Deep, fertile, loose soil is most suitable for its growth, and it can also adapt to heavy loess and barren, dry land.

2. Light

A sun-loving tree, it prefers light. Young plants can tolerate a little shade, but large trees require sufficient overhead light, otherwise they will grow poorly or wither.

3. Temperature

It likes a cool climate and has fairly strong cold resistance. Large saplings can withstand short-term low temperatures of -25°C, but under hot and humid climate conditions, they often grow poorly.

4. Watering

Cedars have a certain drought tolerance and are afraid of waterlogging. The potting soil should preferably be kept moist. Water only when the potting soil has dried out completely, and water thoroughly when you do. During long periods of continuous rain, make sure water does not accumulate in the pot. You can tilt the pot on its side to help drainage, and restore the pot promptly after the rain stops.

5. Fertilizing

For cedars, fermented and decomposed human manure and cake fertilizer are suitable. For home use, cake fertilizer is the main choice. The best time to fertilize is April to May. Be careful not to make the fertilizer solution too concentrated, and do not fertilize too often; 2-3 times a year is sufficient.

Cedar Planting Methods and Precautions

I. Growing Methods

1. Watering

Cedars have a certain drought resistance and are afraid of waterlogging. Just keep the soil in the pot moist. Water when it is dry, and water thoroughly, but avoid water accumulation. After rain, be sure to drain promptly to prevent the cedar's roots from rotting.

2. Fertilizing

It is suitable to use fermented and decomposed human manure and cake fertilizer. For potted growing, cake fertilizer is the main choice. The best time to fertilize is April to May. Never make the fertilizer solution too concentrated; it can be applied in 2-3 split applications.

3. Repotting

Generally, repotting is needed once every 2-3 years, preferably before buds sprout in spring. When repotting, replace half with fresh, loose, fertile soil, and cut off any rotten roots. After repotting, first move it to a shaded place for about 15 days before returning to normal care.

4. Pruning

Leader replacement: The cedar has heavy branches, and the leader may be damaged or weakened. A strong side branch must be pulled up and tied well to become the central dominant shoot. This process is called leader replacement.

Shaping: Mainly remove overly dense branches, leggy branches, dead branches, and diseased or pest-infested branches. You can freely shape the tree form according to personal preference. To prevent the cedar from growing too tall, the terminal bud needs to be removed to eliminate apical dominance, which encourages the cedar to sprout more side branches.

II. Precautions

Pests and diseases: When growing cedars in pots, the main concern is preventing and controlling leaf blight. You can spray a 500-800 times dilution of dexon. There are relatively many insect pests, and you can spray a 1000-1500 times dilution of 80% dichlorvos.

How to Make a Cedar Bonsai

1. Choosing a Pot

Cedars are suitable for purple clay ceramic pots, and glazed ceramic pots can also be used. For large bonsai, deep round pots can be used, and various carved stone pots can also be used, but the base of the roots must be secured with metal wire. For medium bonsai, crabapple-shaped or trough-shaped pots are suitable. For small saplings planted together in a forest style, shallow carved stone pots such as white alum stone or marble can be used.

2. Soil

Cedars can use loose, well-drained, slightly acidic sandy loam. For potting, aged garden soil or leaf mold mixed with sand is commonly used.

3. Planting

Spring, March to April, is preferable, and it can also be done after autumn. Cedar saplings dug from the ground must retain their original soil to help them survive. Also thin out dead roots, spread out the fibrous roots, cover with fine soil, gently shake the pot, and press firm with a bamboo stick so that the potting soil and root system are firmly in contact. As for the planting position, it is best for the main trunk to lean toward one side at about 1B3.

4. Shaping

The shaping and styling of cedar bonsai is mainly done by wiring and binding, supplemented by pruning. Wiring and binding are best done in winter and spring, mostly using palm fiber. The cedar's main trunk stands upright and its side branches spread horizontally, so the side branches are often bent into an S shape, while the main trunk is generally not bent, naturally forming a tall-tree shape upward, with an extremely simple and beautiful posture. You can also take 5-7 saplings of the current year, arranged at different heights, and plant them together in a forest style, with dancing branches and leaves, giving a distinctive charm.

5. Tree Form

The cedar tree body is tall and upright, with side branches spreading and drooping flatly. When making bonsai, its natural form must be used. The best tree forms are the straight-trunk style, double-trunk style, slanting-trunk style, and forest style. Through wiring and pruning, the branches and leaves can be made into layered or cloud-like forms. After years of care, it can become a fine bonsai that combines strength and softness with an elegant posture.

Does a Cedar Bear Fruit?

The cedar actually has its own fruit. The cedar's fruit is a cone, appearing overall ovoid or elliptical, and is fairly large, with a round, blunt apex and a short stalk. Inside the cedar's fruit are seeds, and the seeds are also fairly large, appearing triangular.

After reading the description above, do you feel more confident about planting cedars? In fact, the growing method for cedars is not difficult; it just requires being more careful when caring for it. When growing cedars, be sure to pay attention to one thing: it is not tolerant of pollution, so you must give it a healthy growing environment.
