Q.Hello. Can I Use Crystals Inside My Greenhouse? It’s Super Hot Esp During Summer Here In The Philippines.
Will it be okay just to make a little altar for all the plants or I really need to put crystals on top of the soil? I have hundreds of potted plants. Can I just pick a sick plant and put the crystal on top of it? What crystals repel mealy bugs? Thank you very much for your help. God bless.

For a quick and effective way to get rid of mealy bugs, naturally, I recommend Neem oil or its natural ingredient. This is called azadirachtin.

If you are referring to rock crystals, then you can place them in the soil, around the soil, or within the roots.
