Light Requirements

Yucca Rostrata plants tend to thrive in full indirect sunlight where they also have space and light. Excessive sunlight can cause the leaves to become discoloured and spots can appear on the leaves.

Yucca Rostrata plants that do not have bright indirect sunlight will  not bloom and they will develop spindly leaves.  

Temperature Requirements

Extra Tips for Yucca Rostrata Plants

Pests & Diseases

The Yucca Rostrata plant is resistant to pests and disease; however, overwatering can be a problem. Overwatering the Yucca Rostrata will lead to the leaves turning yellow and the roots of the plant will go soft.

One problem that can affect these plants is red spiders however to get rid of them just spray the leaves with water during the drier seasons and you should wipe the dust off the leaves on a regular basis. 


It is very easy to prune the Yucca Rostrata, remove the plant from its pot and prune about half way up the trunk. Use a pair of loopers or a saw to cut at the desired point, which should be at least half way up the trunk. 

Replant the rooted end in a new pot and give it plenty of water to allow the roots to establish.  The leaves of this plant will naturally grow back.

It is a good idea to repot the plant every couple of years and the repotting should be done in the spring months. It is a good idea to opt for a heavy container as this will prevent the plant from tipping over. 


There are two different ways that Yucca Rostra plants can be  propagated which are through replanting the pups of the plant and the other way is using the rhizomes.

Propagation from The Pup

When propagating from the pup which is probably the easiest way and involves planting the pup that is naturally produced by the plant.

Wait until the pups are green before  propagation as this will maximise the potential for the plant to survive. 

Remove the pup from the plant and place them into their own container. It is a good idea to use some rooting powder as this will encourage the plant to establish roots faster, however the roots will grow even without this powder it will just take longer. 

Propagation from Rhizomes

The second method of propagation is done by separating the rhizomes from the plant and replanting them into an appropriate type of soil.

Whatever type of propagation you opt for the plants will need to be given water however avoid overwatering. When there is too much moisture in the soil the pups can be killed, and  plants will divide.

Until the plants have become established, they should only be given a small amount  of water and the soil should only be slightly moist.
