Blue Cypress (Chamaecyparis lawsoniana)
Blue Cypress, also known as Chamaecyparis lawsoniana, is a narrow columnar conifer with bright blue, feather-shaped foliage.
The densely branched conifer makes a fantastic hedge, not to forget the fact that it requires little care. The most attractive feature of this plant is its special color and that’s the main reason why people use it to make hedges.
Care & Advice
If blue cypress is grown in optimal conditions and taken care of, it can live for so many years, giving your landscape a beautiful look for a very long time.
Newly planted blue cypress need to be watered carefully during the initial stages. Water every time the first 5 cm of the soil dries. However, you need to remember that sometimes too much of a good thing can be a bad thing, so don’t over water the plant. Once established, they will not require watering until dry summer seasons.
- Weed control
You also need to remove weeds as soon as they appear. This is important in ensuring that the blue cypress doesn’t compete with other plants for nutrients. Grass is one of the most common weeds that are likely to invade your new hedge plants. Make sure that your hedge has a 50 cm strip that’s completely free of grass. You also need to add a thin layer of mulch around the base of the plant. This will not only reduce the loss of moisture but also discourage the growth of weed.
Fertilizing the blue cypress is only effective when the plant is still young. A plant that’s close to maturity doesn’t need the extra nutrients. Apply an all-purpose fertilizer once in spring and again as you approach the end of summer. Apply the fertilizer according to the recommendations on the package.
One of the main advantages of growing a blue cypress is that they require very little pruning. If you, however, see branches with variegated or colored foliage, then you need to prune more often. Cut off dead branches from the blue cypress by following the dead branch back to the trunk and remove it at its point of origin.
Check to see if there are dead branches causing rubbing wounds and remove them. For branches that are under one centimeter in diameter, use garden clippers, and for bigger branches, use a pruning saw. Don’t use a wound sealant on the tree wounds.
It is important that you space the plants correctly. Young blue cypress plants may appear small but could eventually outgrow their space. This is common with most conifers and they can be replaced. However, their shape and size can be controlled by trimming and pruning them.
Many conifers, including blue cypress, can be trimmed hard and will still grow. However, they will not grow from old wood if pruned into it; therefore, take care. You can prune blue cypress from spring to late summer.
- Protection from animal damage
Cattle, horses, rabbits, and deer can damage the trees. Squirrels are also terrible pests on trees when they get to about 609 cm tall.
