What are the best soil mixes to use in eucalyptus outdoor planters for drainage?

Eucalyptus trees thrive in well-draining soil, making the right soil mix crucial for outdoor planters. The ideal blend should balance moisture retention and drainage to prevent root rot while supporting healthy growth. A recommended mix includes:

1. Coarse Sand or Perlite (30-40%): Enhances drainage and prevents compaction.

2. Potting Soil (40-50%): Provides nutrients and structure.

3. Compost or Organic Matter (10-20%): Boosts fertility and microbial activity.

4. Pine Bark or Coconut Coir (Optional): Improves aeration and moisture regulation.

Avoid heavy clay soils, as they retain too much water. For container-grown eucalyptus, ensure the planter has drainage holes and consider adding a layer of gravel at the bottom for extra drainage. Regularly check soil moisture and adjust watering to keep the roots healthy.

By using this balanced soil mix, your eucalyptus will grow vigorously, even in outdoor planters.
