Here's what all my succulents are planted in looks like.
I mix MG succulent mix with an orchid mix,it says it has fired ceramic granules,select conifer bark & charcoal.The potting medium is regionally formulated with aged (fir or pine bark) here in Ga. it has 45%-55% aged pine bark,arcilite or lava pebbles again depending on region and finally horticultural charcoal.A lot of people have said they didn't think it was a good mixture with the orchid mix.But i haven't lost any plants to root rot in this mixture.I have my desert roses,sans,leaf cactus, asparagus fern etc... planted in it and they are doing great.
Here one of the plants i'm talking about my lights aren't enough or not strong enough,a lot of my succulents have gotten leggy.The sun this season will fix that,they will bounce back from over wintering.I just wanted to find out how to tell when a succulent needs water,the leaves shriveling,seems to me could be a sign but i've been wrong before.Haven't been growing them long enough to know enough.
