Kawelu (Eragrostis variabilis)

Also known as: Variable lovegrass

This perennial grass species shows a range of appearances. Its smooth, upright stems can grow up to or beyond 91 cm in height. The leaves and flower clusters differ in size, with panicles that can be either open and spreading or compact and spike-like. Notably, plants from the main Hawaiian islands appear distinct from those on other islands. Each pound of seeds contains approximately 3,136,000 seeds.

What Is the Ideal Temperature Range for Kawelu?

Ideal Temperature: 65 ~ 77℉

The ideal temperature range for growing Eragrostis variabilis is between 65°F and 77°F. This range provides optimal conditions for growth and allows the plant to maintain its metabolic processes efficiently. Conditions within this temperature range help in maximizing photosynthesis, nutrient uptake, and ensuring robust plant development.

What Soil is Best for Kawelu?

Soil type: Sandy soil, Loam

Soil PH: 6.5 ~ 7.5

Eragrostis variabilis thrives best in well-drained soils as it prevents root rot by allowing excess water to escape quickly. This ensures the roots receive adequate oxygen, promoting robust growth and healthy foliage. This plant prefers soil with moderate nutrient levels, which means it doesn’t require overly rich or fertilized soil. Such conditions help in maintaining balanced growth without excessive foliage or weak stem structures. The plant can tolerate slightly alkaline soils which support optimal nutrient absorption and enzyme activity. This makes the mineral uptake process more efficient, ensuring healthy plant development.

How to Fertilize Kawelu?

Fertilizer type: Balanced

Eragrostis variabilis benefits from a balanced approach to fertilization. Utilize approximately 1 tablespoon of liquid fertilizer diluted to half strength per plant to avoid overfeeding. When opting for slow-release fertilizers, a single application of half a cup per square foot is effective. Adjust based on plant response and local soil conditions.

How to Prune Kawelu?

Pruning Time: Spring, Summer

First, identify any dead or yellowing stems in your Eragrostis variabilis. Gently separate these stems from the rest of the grass to ensure a cleaner pruning process. Snip the identified dead stems near the base of the plant. Be careful not to cut the healthy neon green stems which contribute to the plant's lush appearance. Trim around the base of the plant to maintain a pleasing shape. This can be either rounded or slightly angular, depending on your garden's design needs. More About Pruning Techniques→

How to Propagate Kawelu plant?

Propagate Time: Spring, Early summer

Fill the seed tray with a well-draining seed-starting mix. Moisten the mix slightly, ensuring it's damp but not waterlogged, to facilitate seed germination.

Scatter Eragrostis variabilis seeds over the surface of the mix. Cover them lightly with a thin layer of soil. Maintain consistent moisture by misting the soil gently.

For division propagation, gently dig up the mature plant. Using a sharp knife or spade, carefully separate the root clumps, ensuring each has viable roots and shoots.

How to Repot Kawelu plant?

Repotting frequency: Every 2 to 3 years

Knowing when to repot Eragrostis variabilis involves watching for certain signals like visible roots coming out of drainage holes, reduced growth, or water sitting on the surface longer. If any of these are present, it’s time to consider repotting.

Opt for a pot that provides good drainage. Eragrostis variabilis thrives in containers that ensure excess water can escape, thus preventing root rot. Ideally, choose a pot just a bit larger than the current one to give roots adequate space without overwhelming the plant.

Choosing the right soil is crucial for Eragrostis variabilis. A well-draining, sandy mixture is ideal, as it mimics their natural environment. This composition helps retain moisture without waterlogging the roots, promoting healthy growth.
