Please note: Our Spiral Aloe has been growing *outdoors* in full sun and we recommend...nay we insist!.... it remains outdoors. We cannot guarantee that it is free from garden pests and therefore bringing it indoors could potentially expose your collection to those same pests. Plus, it's used to full sun.  KEEP IT OUTDOORS! :)


The spiral aloe, scientifically known as Aloe polyphylla, is a stunning succulent native to the Maluti Mountains in Lesotho, Africa. Growing spiral aloe outdoors in San Francisco can be a rewarding experience, as the city's mild climate and coastal influences create suitable conditions for this unique plant.

Here's a guide on how to cultivate spiral aloe in San Francisco:

  1. Climate considerations: San Francisco's climate is characterized by mild, wet winters and cool, dry summers. Spiral aloe prefers a Mediterranean climate, and the city's conditions can mimic this to some extent. However, it's essential to protect the plant from excessive rainfall and colder temperatures.

  2. Choose a suitable location: Select a location for your spiral aloe where it can receive ample sunlight. Choose a spot that provides at least 6 hours of direct sunlight each day. While the plant enjoys sunlight, it's also beneficial to shield it from intense afternoon sun, especially during heatwaves.

  3. Soil requirements: Spiral aloe thrives in well-draining soil. Prepare a potting mix using a combination of sandy soil, perlite, and coarse sand. This mixture ensures proper drainage and prevents the roots from sitting in excess moisture, which can lead to root rot.

  4. Planting: If you're growing spiral aloe outdoors in the ground, ensure the soil is well-draining. If the soil is clay-heavy, consider amending it with compost to improve drainage. Dig a hole slightly larger than the plant's root ball and place the spiral aloe in the hole, ensuring it sits at the same depth as it was in its previous container.

  5. Watering: In San Francisco's mild climate, spiral aloe requires regular watering during the growing season (spring and summer). Water the plant deeply but infrequently, allowing the soil to dry out between watering sessions. During the dormant season (fall and winter), reduce watering to prevent overhydration.

  6. Temperature and frost protection: While spiral aloe can tolerate cooler temperatures, it's crucial to protect it from frost. San Francisco occasionally experiences light frost, so it's advisable to cover the plant with a frost cloth or move it indoors during colder nights. Ensure the plant is in a sheltered location to minimize exposure to strong winds.

  7. Fertilization: Apply a balanced, diluted fertilizer during the active growing season to provide essential nutrients to the plant. Use a succulent-specific fertilizer or a well-balanced, water-soluble fertilizer at half-strength. Avoid fertilizing during the dormant period.

  8. Pruning: Prune spiral aloe sparingly, primarily to remove dead or damaged leaves. Use clean, sharp pruning shears to make clean cuts near the base of the plant. Avoid excessive pruning, as the spiral aloe's distinctive spiral shape is its main attraction.

  9. Pest and disease control: Spiral aloe is generally resistant to pests and diseases. However, keep an eye out for common succulent pests such as mealybugs, aphids, and scale insects. If you spot any infestations, treat them with an appropriate organic insecticide or use a cotton swab dipped in rubbing alcohol to remove them manually.

  10. Propagation: Spiral aloe can be propagated from offsets or seeds. Offsets, also known as pups, are miniature plants that grow at the base of the main plant. Gently separate the offset from the parent plant, allow the cut to dry for a few days, and then plant it in well-draining soil. If starting from seeds, sow them in a well-draining soil mix and keep them warm and moist until germination occurs.

Remember, spiral aloe is a slow-growing plant, and it requires patience to see its mesmerizing spiral pattern fully develop. With proper care and attention to San Francisco's unique climate, you can successfully cultivate this extraordinary specimen plant. 


If you choose to grow spiral aloe indoors as a houseplant, here are a few more tips:

Choose a suitable location: Select a bright spot in your home that receives ample sunlight. Ideally, place the spiral aloe near a south or west-facing window where it can receive at least 6 hours of direct sunlight each day. If natural light is limited, you can supplement it with artificial grow lights.

Pot selection: Choose a well-draining pot with drainage holes to prevent water from pooling at the bottom. Select a pot that is slightly larger than the root ball of the plant, providing enough room for growth. Use a pot with a deep base to accommodate the spiral nature of the plant.  We strongly suggest terracotta 

Soil requirements
: Use a well-draining succulent potting mix or create your own by combining equal parts of sandy soil, perlite, and peat moss or coir. This mixture ensures proper drainage and prevents waterlogging, which can be detrimental to the plant's roots.
