Tetragonia decumbens (dune spinach or sea spinach) is a coastal shrub, native to southern Africa.

A note from PlantMom

Coast Lettuce has moderate resistance to disease and can be vulnerable to problems like leaf spot. Its vulnerability to insect pests depends on the variety, though most varieties are not very pest-resistant. For care, Coast Lettuce requires regular watering and fertilization, along with frequent removal of yellow leaves. It is important to manage pests and diseases as they arise and to harvest the plant in a timely way. Coast Lettuce is appropriate for people who can spend some time and energy on routine care.

CARE GUIDE

How to keep Tetragonia Decumbens.

Light

Coast Lettuce comes from places with plenty of sunlight, such as open fields and sunny meadows. It prefers full sun but can also tolerate partial sun.

Water

To properly care for Tetragonia decumbens, you need to water it carefully, considering factors such as the weather, the condition of the plant, the soil moisture, and the type of pot. During its dormant period, reduce the frequency of watering to once every one to two weeks, especially in hot or cool conditions. In summer, water the plant in the evening to help prevent root rot. Pay attention to the plant's symptoms and the weight of the soil to determine if it needs water.

Temperature

For Coast Lettuce, moderate temperatures are preferable, similar to what most people find comfortable. It does best in conditions that are neither very hot nor very cold. The main problem with high temperatures is the risk of sunburn, so providing some shade in summer is recommended to prevent excessive heat. When temperatures fall, Coast Lettuce becomes dormant. If continuous growth is wanted, higher temperatures must be maintained during winter. Frost can damage the plant and should be avoided.

Fertilizer

To maximize yield, Coast Lettuce does well with regular applications of a balanced fertilizer, especially one high in nitrogen. Apply fertilizer before planting, at planting, and when seedlings are 2 inches tall. Adding compost or manure also gives a steady supply of nutrients. Insufficient soil nutrients cause underdeveloped leaves and stems, inferior flavors, thin stems, and a possibly bitter taste.

Pruning

Tetragonia decumbens is a salt-tolerant plant with a sprawling habit and succulent leaves. Pruning it in early spring can promote vigorous growth, improve air circulation by removing dead or diseased branches, and encourage a more compact shape. This practice enhances the plant's overall health and aesthetic appeal.
