Blue cypresses grow very quickly in a favorable location. They retain their blue-green needles even in winter. But they need enough nutrients to do this. However, the conifer does not get an oversupply. How to properly fertilize blue cypress trees.
How should you properly fertilize blue cypress trees?
Blue cypresses should be regularly supplied with compost, horn shavings and mulch made from lawn clippings or leaves in the first few years. Older plants generally do not need any additional fertilizer, while potted plants should be fertilized regularly with commercial cypress fertilizer.
Planting blue cypresses in a favorable location
Before planting blue cypresses, you should prepare the soil. In principle, the conifer copes well with most soils. It just doesn't thrive on very calcareous soil. Here you can help with some peat.
Mix the soil in the planting holes with mature compost or horn shavings to give the young plants a good start.
Materials for fertilizing and mulching
- Compost
- Horn shavings
- Lawn cutting
- Leaves
- Cypress fertilizer from specialist retailers
Fertilize young blue cypresses
Until the young blue cypresses have developed a large root system, they need additional fertilizer to ensure the nutrient supply in the first few years.
Spread a layer of mulch under the trees. Grass clippings and leaves are well suited.
The mulch cover simultaneously prevents the soil from drying out and the emergence of weeds.
Older Blue Cypress trees are self-sufficient
You generally don't need to fertilize well-established blue cypresses. They have such a branched root system that they can take care of themselves.
Mulch blankets are also recommended here. Also carefully work some ripe compost into the top layer of soil under the blue cypress in spring and autumn.
Fertilize blue cypresses in the pot regularly
The blue cypress cannot take care of itself in the pot. Here you have to fertilize regularly so that the ornamental tree stays he althy and grows.
If you don't have compost, use a commercial cypress fertilizer and apply as directed.
Brown spots despite fertilizer?
If the blue cypress gets brown spots even though you have fertilized it regularly, you should check whether you have given it too much fertilizer.
However, this usually only happens if you have meant a little too well with commercial cypress fertilizer.
Tip
If the blue cypress is suffering or is getting brown spots even though you provide regular nutrients, have the soil checked. Many specialist nurseries offer this service. You can also send soil samples to specialized laboratories by post.
