What Is the Ideal Temperature Range for Caley pea?

Ideal Temperature: 60 ~ 75℉

The ideal temperature range for Lathyrus hirsutus, commonly known as 'hairy vetch', is between 60°F and 75°F. This range supports optimal growth and flowering by providing suitable warmth while preventing stress conditions.

What Soil is Best for Caley pea?

Soil type: Loam, Sandy loam

Soil PH: 6.5 ~ 7.5

Lathyrus hirsutus thrives best in well-draining soils that prevent water logging, which is crucial for avoiding root rot and promoting robust root health. Although not overly demanding, Lathyrus hirsutus prefers moderately fertile soils, which provide necessary nutrients without the risk of over-fertilization that could harm the plant's growth. While the soil must drain well, it should also retain adequate moisture, ensuring that the plant has a consistent water supply, preventing stress from drought conditions.

How to Fertilize Caley pea?

Fertilizer type: Balanced

For Lathyrus hirsutus, it's essential to start with a balanced fertilizer such as a 10-10-10. Use a diluted solution of liquid fertilizer, mixing approximately 5ml of fertilizer per 1 liter of water. When using slow-release granules, apply about 28 grams per square meter around the base of the plant.

How to Prune Caley pea?

Pruning Time: Spring, Summer

Begin by removing any dead or damaged stems, cutting them back to healthy parts. Trim to shape the plant by shortening longer stems and cutting back to a leaf joint. To encourage more flowers, trim back the flowering stems once the blossoms fade. This redirects the plant's energy into producing new buds and prolongs the flowering season. Regularly remove some interior stems to reduce overcrowding. This improves airflow and reduces the risk of disease, while allowing light to reach more parts of the plant.

How to Propagate Caley pea plant?

Propagate Time: Spring, Early summer

Sow Lathyrus hirsutus seeds evenly on the surface of the seed tray filled with potting soil. Cover them lightly with a thin layer of soil to allow for adequate light penetration, promoting germination.

Keep the soil consistently moist but not waterlogged. Use a gentle spray or misting bottle to water the seeds, ensuring that the delicate seedlings are not dislodged.

Maintain a warm temperature between 18-22°C (65-72°F) to encourage germination. Consider using a seedling heat mat to maintain consistent warmth if growing indoors.

How to Repot Caley pea plant?

Repotting frequency: Every 2-3 years

Lathyrus hirsutus should be repotted when you observe roots coming out of drainage holes or the plant looking stunted. Spring and Autumn are ideal seasons, as milder temperatures minimize transplant shock.

Select a pot that is 1-2 inches larger in diameter than the current one. Ensure it has good drainage to prevent root rot, as excess water can quickly damage the Lathyrus hirsutus.

Opt for a well-draining, sandy loam soil. This soil type retains necessary moisture while allowing excess water to escape, providing the best environment for healthy root development.
