Lithops, also known as living stones, are fascinating desert plants that have gained popularity among plant enthusiasts. These small succulents resemble stones and are native to Southern Africa. While they can be grown indoors, many people enjoy growing them outdoors as well. In this article, we will discuss how to successfully grow lithops plants outdoors and provide some tips for their care.

Choosing the Right Location

When selecting a location for your lithops plants, it is important to consider their native habitat. These plants thrive in hot and dry conditions, so they require full sun exposure. Look for a spot in your garden that receives at least six hours of direct sunlight each day.

It is also crucial to ensure that the soil drains well. Lithops prefer sandy or rocky soil that does not retain moisture for long periods. If your garden soil is heavy and retains moisture, consider amending it with sand or gravel to improve drainage.

Planting Lithops Outdoors

Now that you have chosen the ideal location, it’s time to plant your lithops outdoors. Follow these steps to ensure successful transplantation:

  1. Prepare the soil: Before planting, loosen the soil in the designated area to ensure good drainage. You can mix in some sand or gravel to improve the texture if needed.

  2. Dig a hole: Dig a small hole that is slightly larger than the size of the lithop’s root ball. Be careful not to disturb the delicate root system.

  3. Place the plant: Gently remove the lithop from its container and place it into the hole, making sure that the top of the root ball is level with or slightly above ground level.

  4. Backfill the hole: Fill in the hole with the surrounding soil, gently pressing it down to secure the plant in place.

  5. Water sparingly: After planting, water your lithop lightly to help it settle into its new home. Be careful not to overwater, as this can cause root rot. Remember, lithops are adapted to arid conditions and prefer dry soil.

Caring for Outdoor Lithops

Once your lithops plants are in the ground, they require minimal maintenance. Here are some care tips to keep them thriving:

Watering

Lithops have a unique growth cycle that mimics the desert environment. They grow during the winter months and remain dormant in the summer. During their active growing period, water sparingly, allowing the soil to dry out completely between waterings. In contrast, during their dormancy, refrain from watering altogether.

It is important to note that overwatering can be fatal to lithops. Their thick leaves store water, so they can survive extended periods without irrigation. Monitor the weather conditions and adjust your watering schedule accordingly.

Fertilizing

Lithops do not require frequent fertilization. In their natural habitat, they receive nutrients from decomposing organic matter and dust carried by wind. However, you can provide a small amount of fertilizer during their growing season to promote healthy growth. Use a balanced liquid succulent fertilizer diluted to half strength and apply it sparingly.

Protecting from Frost

Although lithops are hardy plants, they are not frost-resistant. If you live in an area with cold winters, it is important to protect your outdoor lithops from freezing temperatures. Cover them with a frost cloth or move them indoors before the first frost hits.

Dealing with Pests

Lithops are relatively resistant to pests and diseases. However, they can occasionally be attacked by mealybugs or aphids. If you notice any signs of infestation, such as sticky residue or white cotton-like clusters on the plant, treat it with a mild insecticidal soap or neem oil spray.

Propagation

If you want to expand your lithops collection, propagation is an excellent option. The most common method is by division, which involves carefully separating the plant into two or more sections. Make sure each division has its own set of roots and leaves. Allow the divisions to dry for a few days before replanting them.

Conclusion

Growing lithops outdoors can be a rewarding experience for any succulent enthusiast. By choosing the right location, providing proper care, and being mindful of their unique growth cycle, you can enjoy these remarkable living stones in your garden. Remember to water sparingly, protect them from frost, and monitor for pests. With these tips in mind, you are well on your way to successfully growing lithops plants outdoors.
