This unique-looking succulent is very forgiving, drought-tolerant, and has pretty much the same basic growing requirements as most other succulent species. So, whether you are an experienced succulent grower or a novice, caring for a Cocoon Plant shouldn’t give you a hard time.

We recommend placing your Senecio Hworthii in a spot of your home or garden where it will get at least 4-6 hours of bright light a day but partial shade in the afternoon. It’s best to keep it away from direct sunlight in the afternoon. That’s because, like most succulents, Cocoon Plant is prone to sunburn. If it’s not possible to provide your succulent with enough sunlight, we recommend adding an artificial light for this plant.

When it comes to fertilizing a Cocoon Plant, you should do it annually, but lightly. Why? Because while the succulent may benefit from the extra nutrition found in fertilizer, too much of it can cause a lot of leggy growth.

Cocoon Plant also requires pruning to keep its upright posture. The weight of new stems and leaves can make it floppy, so it’s best to remove them from the main stem.

Planting Senecio Haworthii

Planting a Cocoon Plant is as easy as it is to care for it. The only important thing during this process is to take its basic needs into consideration. By doing so, your Senecio Haworthii will thrive in your garden or home. You should keep in mind the succulent’s need for a lot of sunlight, its preference for warm temperatures, and its need for soil that provides good drainage.

First, as mentioned above, Senecio Haworthii needs a lot of direct sunlight a day to thrive. When deciding where to plant your succulent, look for a sunny spot where it will get a few hours of sunlight but also partial shade in the afternoon.

Next, remember that overwatering is Senecio Haworthii’s biggest threat. Therefore, it needs well-draining soil to make sure that excess water won’t sit there and make its root rot. Like most succulents, Senecio Haworthii hates wet feet and is susceptible to root rot if you provide it with too much water. So, to protect it from overwatering, use soil that provides good drainage. We recommend using a fast-draining potting soil mix, which you should combine with sand or pebbles to improve water drainage.

Besides that, it is important to consider your Cocoon Plant’s need for warm temperatures. This succulent is not cold hardy, so you must protect it from cold weather or temperatures lower than 30 ° F (-1.1 ° C). For this reason, if you live in a climate where temperatures drop really low during the cold season, it’s best to plant your Senecio Haworthii in a container that you can bring indoors during the winter months.

Watering Cocoon Plant

One of the most common causes of death of the Cocoon Plant is overwatering. Like it is for most succulents, overwatering leads to root rot, meaning that your Cocoon Plant will die.

This succulent is drought tolerant, meaning that it can go long periods of time without being watered. That being said, underwatering is definitely more preferable to overwatering.

How do you make sure you are not overwatering your Senecio Haworthii to death? We recommend using the “soak and dry” watering method. More precisely, you should allow the top few inches of the soil to dry out completely before watering your Cocoon Plant again.

Another way to determine if your succulent needs to be watered is to squeeze a leaf gently. If it is firm, it means that it is holding adequate water, and you should not pour any more water into the plant.

If, by mistake, you pour too much water into your Cocoon Plant’s container, do not let the plant sit in it. Leave it there for a few minutes until the succulent gets as much water as it needs, and then pour off any excess water.
