Sedum Morganianum Care

What Does The Burro’s Tail Plant Look Like And How Big Does It Grow?

The Burro’s Tail plant is a succulent. Like many other succulents, it has waxy blue-green leaves.

Burro’s Tail plant forms long, trailing “vines” that flow away from the plant.

These vines can grow up to 4′ feet long, and the entire plant can be 1′ or 2′ feet wide when well established.

When Does Burro’s Tail Plant Flower?

Burro’s Tail plant produces clusters of star-shaped flowers, usually some shade of red, pink, or purple.

White and yellow flowering varieties can also be found. These clusters appear at the end of the plant’s vines in summer.

What Are The Lighting Needs and Temperature Requirements?

Sedum thrives best in full sun, so set its pot in a nice sunny spot on your plant bench or window sill.

Sedum flourishes in the winter in its native environment. It does not like to be too hot. Otherwise, it will suffer from leaf burn in the sun.

A temperature between 65° and 75° degrees Fahrenheit is probably best. Sedum doesn’t tolerate cold very well, either.

A temperature of 41° to 45° degrees Fahrenheit is perhaps about as cold as it can stand. Sedum is not at all frost-hardy.

How And When To Water And Fertilize Sedum Morganianum?

Sedum naturally lives in a dry environment and can tolerate dry soil fairly well. Therefore, watering it about once every 10 days is probably ample.

A Sedum can even tolerate being watered only once a month. The plant can be allowed to dry between waterings, and new water flow into the dry soil will help it absorb nutrients through its roots.

A sedum will also have a dormant season when it need not be watered at all.

Sedum morganianum is a slow-growing succulent. Therefore, it does not require tremendous amounts of fertilizer.

Liquid fertilizer applied once or twice a year is probably plenty for the needs of a Sedum morganianum.

What Is The Best Soil For Sedum Morganianum And When Should You Transplant?

Grow your Sedum morganianum in a pot containing a mix of sand and soil.

Because it grows in a tropical, arid climate, Sedum morganianum doesn’t like excessive water around it.

A blend of 30% percent sand, 40% percent soil, and 30% percent fine gravel, pumice, or perlite is probably best for the plant as it will allow extra water to drain away quickly while still letting the plant put down roots for nourishment and water.

The plant starts quickly from shoots, so you can make new plants at any time by cutting off a vine or some leaves.

However, older Sedum morganianum plants do not always transplant easily, so it might be better for you to cut off several vines and re-plant them as new plants than repotting the old plant into a new, larger container.

Does Sedum Morganianum Need Special Grooming Or Maintenance?

Other than checking for pests, mildew, and rot, Sedum morganianum requires little special care or maintenance.

The plant usually only needs to remove old or spent leaves and vines occasionally.

Moreover, Sedum morganianum is not poisonous.

How To Propagate Burro’s Tail?

You can propagate the Burro’s tail by cuttings. 

Here’s how to do it:

  • Simply cut off a vine or a few leaves.
  • Let them dry for a few days in the sun before repotting them.
  • Next, plant them in a soil mix similar to your original plant.

Roots should form in a couple of weeks, and the plant can be cared for exactly like the parent plant.

Donkey’s Tail Pests And Diseases

Like many other plants, Donkey’s tail is susceptible to powdery mildew. Powdery mildew can flourish if the plant has too much shade, is too humid, or has poor air circulation.

To get rid of powdery mildew, do the following:

  • First, prune off any visibly affected leaves or vines of the sedum.
  • Then gently wash the rest of the plant with a mixture of water and dish soap or baking soda.

Sedum morganianum can also be affected by leaf, stem, or root rot. These are often caused by fungus. 

Trim off any diseased parts of the plants, and apply a fungicide. Making sure that the sedum has full sun can help prevent the development and spread of fungal rot.

A white fly can also attack Sedum. If the plant is infested, take it outdoors, and spray it thoroughly with water to wash off the flies and larvae

 It is better to wash the plant outside in this way to make sure the flies don’t get back into your house. A sticky trap can also help curb insect infestation.

Suggested Donkey’s Tail Uses

Sedum morganianum, or donkey’s tail, is winter hardy only in and south of zone 10 in the United States.

As a practical matter, it must be grown as a container plant everywhere else.

It does not grow quickly, but patience will be rewarded, as it will send out many trailing vines that might make it especially pleasant for a hanging plant or in locations where it can drape over an overhang.
