Taking care of red lark delphiniums requires some specific steps to ensure their growth and health. These beautiful flowers thrive in rich, well-drained soil with a slightly alkaline pH. If your soil is naturally acidic, it is important to add lime to create the optimal conditions for your delphiniums.
When it comes to feeding, red lark delphiniums are heavy feeders. To promote healthier and stronger plants, it is essential to add compost or manure to the soil. This will provide the necessary nutrients for their growth. Additionally, using a granular fertilizer specifically formulated for delphiniums can further enhance their development.
Here are some detailed steps to take care of your red lark delphiniums:
1. Soil Preparation:
– Ensure the soil is well-drained to prevent waterlogging, which can lead to root rot.
– Incorporate organic matter like compost or well-rotted manure to improve soil fertility and structure.
– Test the soil pH and aim for a slightly alkaline level by adding lime if needed.
2. Planting:
– Choose a sunny location for your delphiniums, preferably with some afternoon shade in hotter climates.
– Dig a hole twice the size of the root ball and place the plant at the same depth it was growing in the nursery container.
– Backfill the hole with soil, gently firming it around the plant.
3. Watering:
– Keep the soil consistently moist, but not waterlogged, especially during the hot summer months.
– Water deeply, allowing the water to thoroughly penetrate the root zone.
– Avoid overhead watering to prevent diseases like powdery mildew.
4. Mulching:
– Apply a layer of organic mulch around the base of the plants to conserve moisture, suppress weed growth, and regulate soil temperature.
– Mulch also helps to prevent soil splashing onto the foliage, which can lead to disease.
5. Staking:
– Red lark delphiniums can grow tall, and their flower spikes may require support.
– Install stakes or a trellis system early in the season to provide support and prevent bending or breaking of the stems.
6. Pruning:
– After the first bloom, cut back the spent flower stalks to encourage a second flush of blooms.
– In autumn, cut back the entire plant to the ground, as this will help promote healthy regrowth in the following season.
7. Pest and Disease Control:
– Red lark delphiniums can be susceptible to pests like aphids and slugs. Regularly inspect the plants and take appropriate measures if infestations occur.
– Provide good air circulation by spacing the plants adequately to minimize the risk of fungal diseases like powdery mildew.
Remember to monitor your red lark delphiniums regularly and adjust your care routine accordingly. Each garden and plant is unique, so it’s essential to observe and respond to the specific needs of your delphiniums. Happy gardening!
