seasonal care tips for thriving lilies in your garden
Lilies are breathtakingly beautiful flowers that can add elegance and charm to any garden. To ensure your lilies thrive and bloom vibrantly, it is essential to provide them with proper care throughout the seasons. Here are some practical tips for maintaining these stunning plants from spring through to winter.
Spring Care: Planting and Early Growth
As the frost begins to thaw, spring is the perfect time to plant your lily bulbs. Choose a site that receives at least six hours of sunlight each day. Prepare the soil by ensuring it is well-drained and enriched with organic matter, such as compost. Plant the bulbs at a depth of about 15 cm, spaced approximately 30 cm apart. Water them thoroughly after planting to settle the soil. During early growth, keep an eye out for weeds that can compete for nutrients. Regularly remove them to give your lilies the best chance of thriving.

Summer Care: Watering and Fertilising
As summer arrives, your lilies will be in full bloom, and proper care is crucial during this time. Water your lilies consistently, especially during dry spells, aiming for about 2.5 cm of water per week. It is better to water deeply and less frequently than to give them a light sprinkling every day. To encourage more robust blooms, apply a balanced fertiliser every four to six weeks. Look for a fertiliser higher in phosphorus, as this promotes strong flower development. Be cautious not to apply fertiliser directly onto the foliage to prevent burning.
Autumn Care: Deadheading and Division
As the blooms begin to fade in autumn, it is essential to keep the plants healthy. Deadheading, or removing spent flowers, encourages the plant to focus its energy on strengthening itself rather than producing seeds. Once the foliage begins to die back, you can also consider dividing your lilies. This is recommended every three to four years to prevent overcrowding and to rejuvenate the plants. Carefully lift the bulbs and separate them, ensuring each bulb has roots attached. Replant them immediately in well-prepared soil.
Winter Care: Mulching and Protection
Winter can be a challenging time for lily bulbs, so take steps to protect them from harsh conditions. After the first frost, trim the dead foliage back to about 10 cm above the ground. This helps prevent diseases and pest infestations. Apply a layer of mulch around the base of the plants to insulate the soil and protect the bulbs from freezing temperatures. Use organic mulch such as shredded leaves or straw, which will also enrich the soil as it breaks down. In particularly cold regions, consider covering the bulbs with a protective frame or fleece to shield them from extreme weather.
Pest and Disease Management
Throughout the growing season, monitor your lilies for common pests such as aphids, snails, and lily beetles. If you notice any infestations, it is best to act quickly. Handpicking pests can be effective for larger insects, while insecticidal soap or neem oil can help with smaller ones. Ensure your lilies have enough air circulation to minimise the risk of fungal diseases. Avoid overhead watering, which can leave the foliage damp and predispose them to diseases like botrytis. Instead, water at the base of the plants to keep the foliage dry.
