Is it normal for my succulents to have dried leaves? (When is it not normal?)
It is normal to have dried leaves as this is part of the metabolism of plants! Usually, one to two leaves drying up at the same time is fine. However, if you realise the rate at which the leaves are drying up is relatively fast, try watering it with a bit more water the in the next few times to see if conditions improve. If conditions still persist, perhaps it has something to do with the roots and soil. Repot the plants so as to provide the plants with healthy soil (aerial and contains nutrients).
