Sword lily, a plant that thrives in light and warmth, yet shuns the chill of winter. It's a sensitive soul, one that demands well-draining soil and a temperature range of 20-25 degrees Celsius for optimal growth.

To propagate this beauty, division is key. New bulbs will bloom the following year, but you can also speed up the process by cutting each bulb into sections with at least one bud and some roots attached. Dust them with grass ash to prevent rot before replanting.

In the field, choose sunlit spots with good drainage and rich soil containing plenty of compost. Avoid muddy areas where water may collect. Before planting, add sufficient base fertilizer rich in phosphorus and potassium to encourage healthy growth.

Plant sword lilies 5-10 centimeters deep depending on soil type and bulb size. Space them 15-25 centimeters apart for proper air circulation. During its growing period, apply three rounds of fertilization: once when two leaves unfurl to promote stem growth; again when four leaves appear to enhance flower stalks; and finally after blooming to support new bulb development.

Sufficient sunlight aids flower bud differentiation and development during summer months. If drought strikes during this time, ensure thorough watering while preventing waterlogging during rainy seasons.

Key points for cultivation include:

Prepare the ground: Choose sandy loam soil that drains well to avoid waterlogged conditions.

Select healthy bulbs: Opt for disease-free bulbs without damage or blemishes.

3.Determine planting times: Plant between April-May or late September-November based on desired flowering periods.

4.Break dormancy: Use high temperatures followed by low temperatures to awaken dormant bulbs if needed.

5.Maintain plant spacing: Vary spacing according to plant variety sizes ranging from 10-20 centimeters square per bulb depth-wise (3-10 cm) ensuring adequate room for expansion while supporting stems against toppling over using nylon mesh grids secured by stakes as they grow taller.

By following these guidelines carefully crafted around your needs – be it early spring blooms or holiday arrangements – you'll have sword lilies thriving within your reach amidst bustling markets filled with an array of vibrant flora waiting patiently under their glassy confines.
