hydrophobic soil on Blueberry
Quick answer
If your Blueberry has hydrophobic soil, the most likely cause is: 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.
Start here:
- 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. 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.
