When transplanting a new plant into a growing medium, the medium must be watered thoroughly so that the medium can settle around the plant's roots. Otherwise, there will be large air pockets around the roots, and the growing medium may be too dry to allow the roots to develop from the existing root ball. Therefore, enough water should be added during the first watering to keep the area around the root ball moist. In general, this means watering from the top and continuing to water until the water comes out of the drainage holes at the bottom of the container. With each successive watering, you can apply less volume, but if you squeeze a handful of the mixture and only one drop of water comes out, the PRO-MIX® may require more water application.

The best way to water any PRO-MIX® product is to water until it is saturated from top to bottom of the container. You will know you have accomplished this when water runs out the bottom of the drainage holes of the container. Then allow the growing medium to dry out without applying additional water. You know you are close to rewatering the product when the surface of the growing medium turns from a dark brown to black (meaning the PRO-MIX® HP® is wet) to light brown / tan color (meaning it is dry enough to rewater).
