How to Plant Cryptomerias

Overview

Cryptomerias--better known as Japanese cedars--come in many varieties and while you should always follow the planting instructions that come with your specific type of tree, cryptomerias can generally be planted in the same manner. Always plant your tree as soon as possible, but keep the roots wet and out of the sun and wind. Cryptomerias are grown in USDA Hardiness Zones 6 to 9 and stay green all year in zones 8 and 9, but will turn brown or purple during the colder months in zones 6 and 7.

Step 1

Cryptomerias--better known as Japanese cedars--come in many varieties, and while you should always follow the planting instructions that come with your tree, cryptomerias can generally be planted in the same manner. Plant your tree as soon as possible, but in the meantime, keep the roots wet and out of the sun and wind. Cryptomerias are grown in USDA Hardiness Zones 6 to 9 and stay green all year in zones 8 and 9, but will turn brown or purple during the colder months in zones 6 and 7.

Step 2

Select a location in full sun to plant your cryptomeria, because it thrives in as much sunlight as possible. However, you can plant it in partial shade if necessary, but it will not be as full and plush as one planted in full sun.

Step 3

Dig a hole that is as deep as the cryptomeria's root ball, but two to three times as wide as its diameter.

Step 4

Amend your soil you just dug out, if necessary. While cryptomerias can grow in most soil types, they prefer soil that is well draining. Mix in a couple inches of compost, sand or peat moss, which will make the soil more conducive to water drainage.

Step 5

Remove the tree from its container, or take off the burlap or netting around the roots. Break up any hard clumps of soil and loosen the roots a bit. You can cut off the outer roots to fit into the hole, if necessary.

Step 6

Place your cryptomeria in the hole. Have a second person, if possible, so one person can hold it up straight while the other backfills the hole. Fill the soil in half way and water well. Pat the soil down to remove any air pockets. Fill the hole the rest of the way with soil, water and pat it down again.

Step 7

Add a couple inches of mulch to help retain water, if desired. For the first year, water your tree about once week. Thereafter, you should not need to water your tree unless drought conditions exist. No other care is needed for your cryptomeria to thrive.
