How to care for Haworthia Cooperi


With the charm of its adorable size that would look just great in any living space, Haworthia Cooperi is a succulent that any collector desires! Plus, they make a wonderful mantlepiece plant, and growing them doesn't need much effort at all. In fact, they can thrive even under neglect, making them very ideal for someone who is always on the go!

To give you a better idea of how easy it is to keep this amazing succulent happy, we have shared everything you'll need to know about growing Haworthia Cooperi.



Native to South Africa, Haworthia Cooperi Var. Obtusa is a stemless, rare succulent that forms rosettes of fleshy, smooth,round-tipped lovely blue-green translucent-patterned leaves that look like little clear watermelons and can grow only between 3 and 5-inches tall and 4-inches in diameter.



Light Requirements

Compared to most succulent plants, Haworthia Cooperi is a bit shy when it comes to light exposure. So if you are planning to grow yours outdoors, find a spot where it can get about 4 to 5 hours of bright, indirect morning sunlight per day. But if you want to grow it as an indoor houseplant, you can display this plant near an east or west-facing window where it can get just the right amount of light it needs.

A south or west-facing window will also do, but you'll have to acclimate the plant first to prevent any sun damage, as these spots usually provide direct sunlight. You can do this by placing your Haworthia Cooperi near the south or west-facing window and putting a few pieces of tissue paper on top of it. Then every couple of days, you can remove a layer of tissue paper.

In case you don't get much light around your area, you can use a grow light to supplement natural sunlight, especially when you see that your Haworthia Cooperi leaves have become softer and greener, or it has started to stretch and lose their compact form. If the leaves have become pale or yellow, or you see that the color of the plant has become very dull, then it's a sign that your Haworthia Cooperi is getting too much sunlight, so consider moving it to a different spot.

Watering Demands

How often you water your Haworthia Cooperi actually depends on its growing environment. But to make it simple, during this plant's growing season, which is from Fall to Spring, make sure to keep its roots hydrated by giving the plant a deep, thorough watering for at least once a week or when the top 1 to 2-inches of the soil feels dry, and don't forget to throw away excess water from the pot's saucer to avoid it from sitting in wet for too long.

In the winter months, when Haworthia Cooperi will go dormant, so reduce your watering to once a month or whenever you see that its leaves are starting to shrivel.

Following this watering routine should keep this plant well hydrated, and at the same time, helps you prevent the plant from getting too much moisture, which is the number 1 cause of root rot.

Ideal Temperature

The ideal temperature to grow Haworthia Cooperi Var. Obtusa is between 68F to 72F. It can withstand cooler temperatures for as low as 50F.

However, extremely cold temperatures can gravely affect the growth of this plant. So if you are located in an area where the temperature tends to drop below 40F, it is best to grow this succulent as an indoor houseplant or plant it in a pot or container where you can easily move it around for protection from any freezing injury.

To be specific, this succulent will do great in USDA zones 9 to 10.

Best Soil Mix

Like any other succulents, Haworthia Cooperi should also be grown in well-drained, sandy soil. You can either create your own soil mix by blending equal parts of regular potting soil, coarse sand, and perlite or shredded bark, or buy a commercially available cactus or succulent soil mix, then add perlite or pumice to promote better drainage.

To do this, you just have to follow 3 simple steps:

Step 1: Get a few healthy leaves from a pest-free mother plant.

Step 2: Place the leaves on a surface for about a day or until they callous over.

Step 3: Once callus has formed, place the leaves at least 2-inches away from each other in a tray filled with fresh moist potting mix.

And you're done! At this point, you should have to make sure to keep the soil moist by misting it with water at least once every 2 days in the morning.

Repotting your Haworthia Cooperi

Repotting Haworthia Cooperi is easy. Plus, you don't have to repot it so often as you will only need to do it when the soil has become poor in quality and you want to give it a fresh new one, or you wish to put it together with your other succulent collections.

Step 1: Remove the small clumping succulent from its container.

Step 2: Shake off any excess soil and rinse the roots using room-temperature water.

Step 3: Plant your Haworthia Cooperi in a new pot and fill the container with a cactus/succulent soil mix.

Step 4: Water thoroughly and place it in a spot where it can get bright, indirect sunlight.

Note: Repotting is best done in spring or early summer, which is when this plant is less prone to stress.
