How to care for the long-lasting succulents


Over watering is what could kill your plants most of the time. Succulents conserve water in their foliage. This is what helps them to thrive in the hot and arid conditions.

However, you need to water them moderately so that it would help them to survive. You need to ideally water them moderately and thoroughly and let the excess water move out from the pots.

Next allow their soil to wither between two watering sessions. If you want to ascertain whether the soil is dry or not, you could simply place the finger in the soil and check whether it is moist or dry.

Generally you need to water them once every one or two weeks when they are at their active growing pace. On the other hand, you need to reduce watering of plants when the weather is too cold.  


Providing a fast draining soil mix is important just like watering the plants well. Literally you cannot reap the best results of proper watering if you don’t provide a soil mix which has excellent drainage.

Succulents don’t prefer to stay exposed to waterlogged soggy conditions. If you accidently do so, it would lead for rot in them.

So, it is mandatory that you go ahead with a soil mix which is fast draining. I suggest you choose a commercially made succulent soil mix and add elements such as perlite to further enhance the draining of the mix.


Majority of the succulents are used to grow in hot and arid drought conditions. However, you need to protect the plants from the intense sunlight especially during midday in the summer. It is noteworthy that young plants will not tolerate direct sunlight at all.
