Hoffman Volcanic Lava Rock 2 qt
- In store pick up or Local Delivery only.
Hoffman Volcanic Lava Rock is a decorative soil cover that can be used indoors or outdoors. It helps retain soil moisture and reduces compaction caused by frequent watering.
For potted or bedded plants
Using lava rock screened (to remove large pieces and also dust) as mulch will not only keep weeds down due to the shading of the ground (most weed seeds need light to germinate) it also retains moisture in the shaded soil beneath it
Careful, though. Since lava rock attracts heat, direct contact can cause your plants to overheat
