Picea is a plant that is native to the mountainous regions of the northern hemisphere. It is a coniferous tree that can grow to be over 100 feet tall. The leaves of the picea tree are needle-like and the tree has cones that contain the tree's seeds. The wood of the picea tree is strong and is often used for construction purposes.

About soil condition, it is good to know that picea like well-drained soils with a least 30% organic matter. They are deep-rooted and prefer a soil pH between 6.0 and 7.5. Picea mariana is especially tolerant of very wet soils and will even grow in sites that are seasonally flooded.
So, like the other coniferous trees, spruce Trees require full sun to grow properly. This means that they need at least six hours of sunlight each day in order to thrive. If they do not get enough sun, they will not grow as quickly or as strongly as they should. Additionally, their needles will not be as green and they may even start to turn brown.
The temperature condition focus is on the impacts of temperature change on (picea). The focus is on how temperature change will impact the growth and development of (picea), as well as the potential for temperature change to impact the range and distribution of (picea). The focus is also on the potential for temperature change to impact the water needs of (picea).
Ideal humidity condition for this plant is 40%-50%. The plant cannot tolerate too much or too little humidity. If the humidity is too low, the plant will become dry and brittle. If the humidity is too high, the plant will become soggy and start to rot.
Mentioning fertilizer, this kind of plant needs little if any. A general purpose 10-10-10 fertilizer can be used when necessary, but be sure to read the directions for application rates. Excess fertilizer will cause the roots to burn.
Pruning is a process of cutting away dead or overgrown branches from a plant. This helps to encourage new growth and keep the plant healthy. It is important to prune picea trees in early spring before new growth begins. This will allow the tree to heal quickly and prevent new growth from being damaged.
Propagation is the process of creating new plants from a parent plant. There are many ways to propagate plants, but the most common method is through cuttings. Cuttings are pieces of the parent plant that are cut off and then planted. The cutting will then grow into a new plant that is identical to the parent plant. Other methods of propagation include division, layering, and grafting. Division is a method of propagation that is often used for perennials. To divide a plant, the root ball is divided into several pieces and each piece is planted in its own pot. Layering is a method of propagation that involves rooting a stem while it is still attached to the parent plant. Once the stem has rooted, it is cut off from the parent plant and planted in its own pot. Grafting is a method of propagation that is often used for fruit trees. To graft a plant, a piece of the parent plant is grafted onto the rootstock of another plant.
Usually, the plant growth rate studies have been done on young trees in nursery conditions. The average growth rate for picea species is between 1 and 2 feet per year, but can vary widely between species and individual trees.apicea omorika has been recorded at 5 feet per year while p. sitchensis growth rates have been as low as 0.3 feet per year. It is difficult to predict growth rates for old trees in the wild.
Common problems for this kind of plant are root rot, needle cast, and canker. Root rot is caused by a fungus that attacks the roots and can kill the tree. Needle cast is a fungus that attacks the needles and can cause them to fall off. Canker is a disease that attacks the bark and can kill the tree.
