Pumice gravel 0-3mm 2 liters

---

Pumice is a porous, spongy volcanic rock. It is significantly lighter than other stones of volcanic origin and is mined in Germany in the Eifel.

Use of pumice gravel:

• Pumice gravel is very popular as an additive for bonsai soil mixtures (approx. 10-20%).
• Can be used as a drainage layer at the bottom of the bonsai pot
• For certain types of plants (e.g. boxwood) pumice can also be used pure
• Sometimes used to increase humidity (pumice + water in the saucer of a bonsai pot)
• Various uses for decorative purposes. The offered goods are very clean.

Beneficial properties of pumice gravel:

• Very good air permeability - so a lot of oxygen gets to the root cells
• Reduces the tendency to soil compaction in substrate mixtures or as an admixture to bonsai soil
• Excellent drainage properties (very good against root rot)
• High lime content - hardly any soil acidification
