How to Grow Crinum Lily

The crinum lilyhas become one of most popular lilies, owing to its beautiful foliage and easy maintenance demands. In comparison with other lily varieties, including hybrids, crinums tend to bloom early and have greater resistance against bacterial diseases and fungal infections. Growing a crinum lily is not demanding, but you should follow some basic guidelines.

Basic Care Instructions

Crinum lily is the sturdiest of all lilies, having no specific insects or pests bothering it. You can use herbal pesticides if the occasional caterpillars are seen in the crinum flowerbed. 

Winter Care

  • Spread generous layers of pine needles and mulch around the base of the flowerbed. You can also use straw leaves.
  • This is useful in temperature regulation and preventing premature sprouting. 

Nutrition Care (Fertilization)

Lilies are dependent on a regular dosage of nitrogen-heavy nutrients.

  • Use nitrogen-rich fertilizers when the green leaves start appearing.
  • Use phosphorus and potassium-rich fertilizers when the flowers are blooming.
  • Except for the organic nutrients added during initial soil preparation, no fertilizers should be added for a month from the day of planting.
  • After the first month has passed, fertilize on a monthly basis.

Pruning & Staking (Growth Control)

  • Top-heavy crinums need to be pruned, as they cut off the sunlight to the lower parts of the plant.
  • You should also prune aging leaves and decaying lily flowers. This promotes new growth on the plant and keeps the flowerbed looking pretty.
  • Staking is done to ground the stems in a firmer way, particularly in soil beds with more clay content. However, staking too tightly could suffocate the stems.
