Lily plants are best grown in full sun or part shade. Choose a location that will receive at least 3 hours of full sun each day. Protection from strong afternoon sun is preferable. If afternoon sun is unavoidable, take extra care with watering to prevent the soil drying out, which can cause wilting.
Lily plants need a well drained soil enriched with plenty of organic matter. Prepare soil by weeding it thoroughly, digging it over to loosen it and adding aged animal manure or compost. Keep the area free of weeds until planting.
Lily plants can be grown in containers. If possible choose a variety that’s recommended for container growing. Use a good quality potting mix and make sure your container is large enough for mature plants; a minimum of 20 litres is recommended for lilies. During the growing season, keep in mind that container grown plants may need additional fertiliser to encourage healthy growth.
Lily bulbs are fresh (not dormant) and need to be kept moist until they are planted. Plant bulbs as soon as possible after purchasing them. Plant lily bulbs directly into the garden or container in clusters so the stems can support each other as they grow.
Lily plants may need watering during the growing season. Water when the soil is dry about 5cm below the surface (test this by scratching away a little soil with your finger). Water deeply in the early morning or late afternoon. Avoid watering the leaves of plants to avoid fungal diseases. Learn more about watering here.
To help keep moisture in the soil and keep the lily's roots cool, apply a thick layer of organic mulch such as lucerne or pea straw before summer.
When plants begin to form buds, apply a balanced liquid or slow release fertiliser at the recommended rate to prevent the lower leaves from turning yellow.
Lilies should be ready to harvest in approximately 70-120 days.
Cut flowers when the first buds just begin to open. Cut about halfway down the stem, strip the lower leaves from the stem and plunge it into a bucket of clean water for a few hours before recutting the stem at a 45° angle and transferring it to a vase.
Optional: The anthers can be cut or gently pulled off each flower to stop pollen falling onto the petals and staining tables or fabric.
If plants have been left to bloom in the garden, cut back after flowering, leaving half the stem to provide nutrients to the bulb so it will flower next year.
When plants have finished flowering, top dress with compost or apply a balanced slow release fertiliser at the recommended rate. When foliage has completely died, cut the stem at ground level.
Bulbs can be left in the ground to flower in future years. If the clump becomes overcrowded, lily bulbs can be lifted, divided and replanted in late autumn or early winter.
Like all plants, lily is susceptible to some pests, diseases and other problems. Below is a list of the most common problems gardeners encounter when growing lily plants:
