Water retention is important for plants to survive when the weather is hot. Adding clay pebbles in the soil is a great way to regulate soil moisture. Water seeps into the pebble and accumulates there. When the soil is dry, water is released to nearby plant roots. Wet the clay beads with rainwater to keep the pores from stopping up due to excess minerals in tapwater.

Clay pebbles excel at keeping the air around the plant moist. Many houseplants come from the tropics, where air humidity is naturally high.

Clay pebbles can raise moisture levels from 40-50% relative humidity to a more comfortable 80 % moisture.

  • Drainage –  Pour a layer about an inch or two thick at the bottom of the container and this will increase air circulation
  • Repotting – To spur the growth of roots, it can be a good idea to mix clay pebbles into your special repotting soil mix to about 10% of the total volume.
