Hydrophobic Soil

Our analysis of 3 verified rescue cases across 3 plant species shows exactly what causes hydrophobic soil and the most effective fixes.

Quick Summary

Blueberry container mixes rely heavily on peat moss for acidity. If peat moss dries out completely, it becomes hydrophobic, repelling water so that it runs straight down the sides of the pot, leaving roots dry.

Most Effective Solutions

  1. 1 Bottom-water the container by placing it in a deep saucer or tub of water for 1-2 hours until the soil rehydrates and becomes heavy.
  2. 2 Add a few drops of mild, biodegradable dish soap to the watering can to break the water's surface tension and help it soak in.
  3. 3 Bottom water by soaking pot in tray for 30-60 minutes
