How to Water Crassula Muscosa (Rattial Crassula)

As Crassula Muscosa is the native from the warmer and rocky place it doesn’t need more water typically in winter.

It is best to water your succulent when you fell that the soil is very dry.

But how can you identify that your rattail crassula needs watering?

Pro Tip: I personally identify the watering need of succulent through two-inch finger rule. Two-inch finger rule is very simple when you want to identify the watering need of your succulent place the finger two-inch deep in the soil. If you feel that moisture is present in the soil then don’t water it until the soil become De-moisturized. When you water the zipper plant please don’t overwater because it can produce rot in the roots.

Lighting Requirments

As all succulent enjoys the sunlight, princess pines (zipper plant) also enjoys the sunlight because it gives energy to the roots and leaves.

This succulent likes both direct and indirect sunlight.

Fortunately, if you are living at a place where summer is mild then you can place it outdoor but if the summer is very harsh with intense sun rays then it will burn your rattail crassula.

I suggest you keep indoor your plant if you are living in a place where summer is harsh.

Growing indoor is not a difficult task for you just you need to find out a place where sunlight reaches very well then place your plant.

It only needs 6-7 hours’ indirect light however excess indirect couldn’t affect the crassula Muscosa.

If you don’t have any sweet able place where indirect sunlight comes you can use artificial lights to grow your plant but I prefer natural light pollution-free light.

NOTE: in summers excess amount of direct sunlight could negatively affect your watch chain plant it can burn the leaves or your plant may begin to stiffen and dry.

Temperature required for Rattaill Crassula

Crassula Muscosa is not cold hardy it can’t bear the temperature below 20oF (-6.7oC).

You have to keep your watch chain plant indoor if you fell that temperature is very low.

I suggest you keep your watch chain plant indoor every night.

On the other hand, the zipper plant can’t bear the high temperature and intense sun rays.

if you want to grow your watch chain plant outdoor you have to analyze the temperature with any temperature measuring instrument.

If the temperature is very high with intense sun rays, then you have to move your plant indoor otherwise your plant maybe burn.

Humidity Required For Rattail Crassula

Crassula Muscose doesn’t like humidity it requires dry area for grooming.

An excess amount of humidity can destroy your succulent within a few days especially in winters.

PRO TIP: if you feel that humidity, Moisture or fog is present in the environment please keep move your watch chain plant to indoor. I suggest you observe humidity on a daily basis with any humidity measuring device.

Soil and container

Soil and container is the essential material to grow your crassula Muscosa.

Chose a container with average size which has a drainage hole form which water could drain out.

Also, use the soil which has properties to drain out water completely.

Please don’t use the soil with moisture it can destroy the roots of your watch chain plant.

Fertilizer and feeding

Typically watch chain doesn’t require fertilizer in all seasons but if you want to accelerate the growth of your plant you can use fertilizer in summers.

The method of using fertilizer is very simple just you have to Mix up the fertilizer with water and release it slowly in the soil of your plant

In summers you can feed your rattail crassula monthly or weekly depending on the concentration of fertilizer with water.

If the mixture of water and fertilizer is light you can use weekly otherwise if the mixture is dense you can use it monthly.

Don’t overfeed your watch chain because it can affect negatively use a required dosage of fertilizer.

NOTE: A newly purchased or newly repotted rattail crassula doesn’t require fertilizer for one year.

Repotting Process

Repotting plays an important role to groom your crassula Muscosa.

I suggest you repot your every succulent after 10 months not only rattail crassula.

The reason is simple their old soil loses some amount of nutrients.

Repotting is a very simple task just you have to remove the plant from old soil and plant it into the well-drained new soil.

I suggest you repot your plant when the old soil becomes too dry.

Once you remove the plant from the old soil remove the whole old soil from the roots of the watch chain by shaking its roots.

After that, your task is to remove the all damaged roots and plant it into new soil and container

Propagation of Crassula Muscoso

Propagation of this plant is very simple and easy you can propagate it from the stem with a sharp knife or the pair of scissor.

Here is the step by step guide to propagating your rattail crassula

Propagation of Rattail Crassula

 STEP 1:  select a healthy steam

 IMPORTANT STEP 2:  cut down the 2cm centimetre steam from the plant.

2 cm centimetre is the ideal length to grow a new zipper plant.

PRO TIP: before propagation, I suggest you mark the 2 cm with any scale in order to work accurately.
 STEP 3:  place 2 cm stem at a dry place for several days.

 IMPORTANT STEP 4:  after several days when your stem becomes perfectly callous then place it in well-drained soil.

 STEP 5:  water it when you feel that the soil become too dry.

Zipper plant may require 3 weeks to grow new roots from stem.

NOTE: if you want to grow another watch chain from the stem you have to select a dry place where the temperature is about 65-70oF with a lot of brightness.

Various diseases and pests’ problem in Crassula Muscosa

Crassula Muscosa is defensive less to mealy bugs and other large scale insects.

Overwatering, poor quality and very low temperature is also the cause of root rot.

Poor quality soil means the soil with more moisture and less able to drain out the water during the watering process.

If accidentally your crassula lycopodioides (zipper plant) is affected, then treat it with neem oil insecticide or any other powder form insecticide.

Once your plant is affected your first task is to move affected plant to another area and remove the affected steam with a knife.

After removing the affected area keep apply the neem oil for a few days until your plant will groom.

  1. Hi There –
    My crassula muscosa is a new plant in my home, and i have noticed that some of the leaves are turning brown and crispy. My guess is that it is low on water, but since this is my first time owning one, i wanted to get some insight on overwatering vs underwatering symptoms for this particular plant.
    what have you observed?
    Thank you,

    • Hi thank you for reaching out,
      it probably needs more water but a picture would be more helpful. If it feels squishy it is under watered, but if the leaves feel firm then it could be a light issue or root rot.
