helps keep water in the soil and keep weed growth down
. However, lava rock absorbs heat during the day, and releases it at night, thereby increasing water loss.

How long does it take for plants to grow after a volcanic eruption?
Mueller-Dombois and H.J. Boehmer said that lower plant life-forms can begin to develop as early as one year after an eruption. ‘Ohi'a have been observed growing as early as four years after a flow, but is takes another
200 to 400 years
for the plants to mature and become well established across the area.

the bottom of plant pots. One rock to cover the drainage hole is enough – just enough so that the soil doesn't leach out of the bottom but water can flow freely through the pot. Putting rocks in plant pots doesn't aid drainage or improve air circulation.
Is black lava rock safe for plants?
