Top dressing and soil mixes
Top dressings and soil mixes are worthy of their own threads. Ornamental dressings are frequently used on show plants. In my area, some nurseries use a lot of perlite in their mixes to insure good drainage. Perlite floats and will easily wash out of the pots. Rock top dressings prevent this washout while maintaining evan more rapid drainage near the base of the plant. I suggest you join a Cactus & Succulent Society if there is one anywhere near you. Members can fill you in on some of the best ways to cope with your particular needs. RON
