Scientific Name

Sauropus androgynus belongs to the Phyllanthaceae family and is commonly known as Katuk or Sweetleaf Bush. It is grown as an edible leafy green as well as an attractive tropical shrub.

Classification

Katuk is a perennial edible shrub. It produces abundant green foliage and can develop into a 4–6 foot plant when grown under favorable conditions. The young leaves and shoots are particularly valued as a leafy green, while the plant also produces edible flowers.

Origin

Katuk is native to Southeast Asia and has long been grown as a leafy vegetable in tropical regions. Its ability to tolerate a wide range of light conditions makes it adaptable to many garden environments.

USDA Hardiness Zones

Katuk grows best in Zones 8–11. It is a warm-weather plant and should be protected from freezing temperatures. In cooler regions, it can be grown in containers and moved indoors or into a protected location during cold weather.

Height Potential

Katuk can reach approximately 4–6 feet tall when mature. Regular pruning can keep it smaller and more manageable.

Planting

Plant Katuk outdoors in a location with suitable soil and good drainage. Katuk can also be grown in containers. Choose a container with adequate drainage and gradually move the plant into larger pots as it grows.

Light

One of Katuk's most appealing characteristics is its flexibility when it comes to light. It can grow in full sun to full shade, or anywhere in between. For container-grown plants, place Katuk where it receives the amount of light appropriate for your growing conditions and monitor its growth.

Soil/Watering

Katuk has medium watering needs. Provide regular water, particularly while the plant is establishing and during hot or dry weather. 

Fertilizer

Katuk benefits from regular feeding during active growth. We recommend a 1-1-1 fertilizer for Katuk plants. Avoid overfertilizing, particularly when caring for a newly arrived baby plant.

Fruiting and Harvesting

Katuk is primarily grown for its edible leaves and flowers. The leaves are high in protein and can be harvested as the plant grows. Regularly harvesting young leaves and shoots can help maintain a compact, productive plant.

Common Pests

Katuk is generally an easy-to-grow plant, but as with any garden plant, it is a good idea to regularly inspect the foliage for signs of pests. Common pests include spider mites and aphids, which Neem oil or insecticidal soap can be used for control. 

Toxic to Pets?

There is some debate whether Katuk is toxic to pets, as it can be potentially toxic if consumed in large quantities. 

After Arrival Care

Please give your plant a little TLC after its journey through the mail 📬. Here are a few steps we recommend:

  • Unwrap immediately to provide fresh air to the plant and soil.
  • Wait a few days before exposing to full sunlight so your plant can adjust after being in a dark box for several days.
  • Always protect from heat and cold because temperature extremes can be stressful or deadly for plants.
  • Water. Your baby plant may be parched and even a little wilted but thorough hydration will help it recover.
  • Grow out in a larger pot to increase your chances of success—i.e., a quarter gallon—Then transplant to the ground or the next pot size up once the roots fill to the bottom. This will help the plant get sufficient water and nutrients directly to the roots.

Repotting

We highly recommend growing your baby plant out in a larger pot 🪴 to increase your chances of success 🏆. Repotting helps focus the water and nutrients directly towards the roots. If the pot is too large or if your baby is planted in the ground, the water and nutrients have more room to spread to the wrong places where they aren’t needed. This can be extra detrimental to a baby plant that needs all the support it can get as it’s growing up.

You don’t have to repot immediately, but the sooner you do, the more room it has to grow. 

Here are some general repotting tips:

  • Start with a pot that's 1-2 inches larger in diameter than the starter-sized pot it came in. A pint or quart would be great.
  • Transplant to the next pot size up once the roots fill to the bottom.
