The tri-color beech tree prefers shade as it usually grows in forests. A shade cloth must be provided if your plant is located in a location that receives prolonged sunlight.

Soil pH should be kept between 5.5-6.5. You can use organic compost there to increase the water-holding capacity of the soil.

Water the tree regularly for the next two years after planting.  A soil dryness test is important before watering. Salt water should be used. You can use a water filter to ensure water quality.

The temperature should be kept between 70-75°F.  Apply enough fertilizer once or twice a year to support plant growth.

Before planting your tricolor beech, take some good quality garden soil and add 30% perlite and 20% bark mix then plant. You can also add a little amount of organic compost to it.

Regular pruning is recommended. Remove a branch where it rubs against another to avoid damaging the bark, which can lead to the development of fungi infections. The optimum time to prune is in the late winter dormant period.

A good quality insecticide is the best way to protect plants from pests.  Also, you can spray six tablespoons of a dishwasher and two to three tablespoons of vinegar in one liter of water once a day for two weeks. 

Apply a fresh water spray to the plant every morning and evening to protect the plant from new pests.

4. Diseases

Root rot, Canker, and Beech bark disease are the most common diseases of tricolor beech trees.  All three diseases can be fatal to your plants. So it is important to know the reason behind them.


  • Waterlogged soil
  • Low humidity
  • fungal attacks.

Treatment Guide

Care should be taken in soil selection and the plant should not be overwatered.  If symptoms of root rot appear, plants should be replanted if they are young. Apply antifungal powder if the tree is mature. 

Below 40% humidity is dangerous for tricolor beech trees. So maintain at least 50% humidity. Regular fresh water misting can be a wise idea.

Fungicides must be applied to prevent canker diseases. If your tree is already affected, prune the dead branches immediately. Remove the infected part carefully if your tree has the bark-losing disease.

How does an underwater tricolor beech tree look?

Ans: When you don’t apply enough water to your plant, the plant’s growth will be stunted. The leaves will first turn pale and later turn yellow or brown. The tree will become weak. Weak trees are prime targets for pests, so infestations will increase.

Which Fertilizer is good for Tricolor beech trees?
