Spruce Bonsai (Picea): Types, How to Grow and Care

Sharing is caring!

It may be a tree that you think of more often as a Christmas tree, but the reality is that spruce is an evergreen coniferous tree with plenty of other uses, too.

Not only is it prized for use in woodworking, but spruce is also a popular bonsai plant. Growing up to 200 feet tall when mature, these trees can be trained to a diminutive few inches in the bonsai culture.

Types of Spruce Bonsai Tree

Spruce trees fall into the Picea family. Here are some of the most popular types of picea bonsai trees.

Picea abies 

P. abies, or Norway spruce, is traditionally used as a Christmas tree and has reddish brown bark and shiny green needles. It is hardy in zones 2B through 7a, making it a good choice for northern bonsai growers. Of course, it can also be cultivated indoors. 

There are several cultivars of P. abies that can be used in bonsai, too, including P. abies albertiana ‘conica,’ P. abies ‘Echiniformis’ (a natural dwarf variety that grows slowly and produces more densely-packed foliage), P. abies ‘Little Gem,’ (prized for its tiny needles) and P. abies ‘Nidiformis.’ 

Some other cultivars to consider include:

  • P. abies ‘Pumila’
  • P. abies ‘Pumila Nigra’
  • P. abies ‘Pygmaea’
  • P. abies ‘Variegata’

Picea engelmannii 

This kind of spruce is known as Blue Engelmann spruce or dwarf Alberta source. Hardy to zone 3, it has fragrant needles that smell like camphor when they are crushed. It’s great for indoor growing and also produces delicate orange cones. 

Picea glauca 

P. glauca, or white spruce, has blue green needles that are somewhat prickly to the touch. It is hardy in zones 2-5 and has a refreshing aroma. It’s important to note that this spruce bonsai tree does not do well in the heat. 

There are several cultivars of P. glauca for you to consider as well, including:

  • P. glauca ‘Albertiana conica’
  • P. glauca conica (this one is very susceptible to spider mites but withstands heat and dry spells better than other bonsai options)
  • P. glauca densata 

Picea glehnii 

This kind of spruce bonsai is known by many other names including silver fir, Edo spruce, common Ezo spruce, and Sakhalin spruce. While it’s popular in Japan, it may be harder to acquire in the United States because of export laws. 

Picea jezoensis 

Also known as Yezo spruce, H ondo spruce, jezo spruce, or Yeddo spruce, this type of spruce for bonsai is hardy to zone 5 and needs to be grown in somewhat shady conditions. 

Picea mariana

Also known as black spruce, this species can also be found with a dwarf cultivar, ‘Nana.’ It grows in a narrow form and also comes in a weeping form. It is hardy in zones 4-7. 

Picea orientalis 

Known as Caucausain or Oriental spruce, this kind of spruce is perfect for bonsai because it has unique purple cones and short needles. It is hardy to zone 5 and when found growing in the wild, can grow to 50 feet or more. It’s one of the best options if you plan on using it as a bonsai specimen in a hot, humid environment. 

Picea oungens

Also known as Montgomery spruce, this kind of bonsai tree has blue needles and naturally grows in a compact form, making it perfect for bonsai. 

Picea pungens

You might hear this kind of spruce tree referred to as ‘River Road’ or as blue spruce. It can grow to zone 3 and survives some of the highest altitudes. 

Picea rubens

Picea rubens, or red spruce, can also grow at high altitudes and has lovely rich purple bark that turns reddish on older trees and gray at high altitudes. It has aromatic candles that smell just like apples. 

Picea sitchensis 

This kind of spruce is frequently referred to as Sitka spruce and is the fastest growing spruce in the world, perfect for us impatient bonsai hobbyists! 

Picea torana 

This kind of spruce is also known as tiger-tial spruce and can be found up to zone 6. 

Growing Spruce Bonsai from Seed or by Propagation

Spruce trees can be propagated both from seed and cuttings. Cuttings are best taken in the late summer. 

How to Care for Spruce Bonsai

Here are some bonsai care tips you can follow:


Place your spruce bonsai tree in full sun during the growing season. It can tolerate either direct or indirect light. During the winter months, however, when the plant is dormant, put it in a bit of shade. If you are growing this bonsai tree outside, provide it with some protection from the frost. When its roots become frozen, it won’t be as adept at getting water to the foliage and it can thus dry out. 


As soon as you notice the soil has begun to dry out, water your spruce bonsai. Avoid keeping the roots soggy but make sure adequate moisture is provided even during the winter months. 


You can use a solid organic fertilizer once a month or a liquid fertilizer every seven to ten days. Spruce bonsai trees benefit from fertilizers that are designed specifically to feed the leaves, usually with chelates, iron, and high levels of nitrogen to improve the color and growth of the foliage. 

Potting and Repotting

Repotting your spruce bonsai should be done once every three years for newer, younger trees. For older trees, you can wait longer, usually every four or five years, since the growth will be slower. To do this, just prune the roots slightly, removing no more than a third of their growth. Use a well-draining soil mix when you put the trimmed plant in a new container. 

Pruning Spruce Bonsai

Spruce bonsai has a unique whorled pattern of growth, causing several branches to grow at the exact same height on the trunk of the tree. To prune your bonsai, you should remove all but one branch. You can also pinch new shoots in the spring while they are still soft. 

If you need to prune longer branches, just shorten them so they are smaller twigs near the trunk. Leave buds and needles on branches you intend to keep. 

Pests and Diseases

There are several pests and diseases to which spruce bonsai is unfortunately prone. Watch out for pests like green spruce aphids, spruce spider mites, and source needle miners, along with fungal diseases like rust.

All of these are best prevented by growing your spruce bonsai indoors and following the steps listed above for caring for your plant. A healthy plant will be able to withstand disease and pest infestation with ease. 

If pests and fungal diseases become too much for your tree to bear and are causing serious damage, stunted growth, or defoliation, you can use a pesticide or fungicide to get rid of them. 

Where to Buy Spruce Bonsai

You can buy spruce trees for bonsai anywhere you would ordinarily purchase spruce trees for cultivation in the landscape. Shop your local tree nursery or online at your favorite bonsai specialty shop for trees that were grown from certified stock.
