Here's how to get the most out of these vibrant plants:

1. Sunlight

Princess lilies thrive in locations with full morning sun and shade in the afternoon. These hardy flowers bloom from spring to summer but once the temperatures get too warm, they cease blooming until the weather cools down again.

2. Soil

Alstroemeria enjoy well-drained soil. Soil that is water-logged can lead to oxygen deficiency, resulting in drowned and rotted roots. To improve your soil drainage, raise your garden beds or mix in organic matter such as manure or compost into your soil.

3. Water regularly

Princess lilies benefit from a regular watering schedule. Your soil should be consistently moist but not soggy as this can lead to rotting roots.

4. Prune when needed

As your princess lilies fade out of bloom, look to deadhead your flowers. Deadheading encourages plants to set more flower buds and helps your flowers to conserve energy. It is best to remove the entire stem, by twisting and pulling it out of the ground. This not only keeps your garden tidy, but allows new stems to grow and replace old ones.

5. Watch for pest and disease

Alstroemerias are generally hardy, but keep an eye out for:

• Slugs and snails: Especially after rain or in damp areas
• Aphids or thrips: Check new growth and undersides of leaves
• Crown rot or fungal spots: Ensure good air circulation and avoid overhead watering

Tip: Companion planting with herbs like basil or flowers like marigolds may help deter some pests naturally.

6. Protect from extreme weather

These plants can be sensitive to:

• Frost: Use a garden fleece or mulch heavily during winter if you live in a cooler climate
• Extreme heat: Provide afternoon shade and increase watering if needed

Tip: Container-grown princess lilies can be moved to sheltered spots in extreme conditions, giving you more control over their environment.

7. Feed with light, regular nutrition

Alstroemerias benefit from a light feeding schedule, especially during the growing season.

Fertiliser tips:

• Use a balanced, slow-release fertiliser (like 10-10-10) in early spring
• Supplement with liquid seaweed or fish emulsion every few weeks while flowering
• Avoid high-nitrogen fertilisers, as they promote leaf growth at the expense of blooms.
