Edging Lobelia Care: A Comprehensive Guide to Growing Trailing Lobelia Plants
Introduction
Edging lobelia, a fast-growing, trailing herb, is a beautiful and versatile plant that can add color and charm to any garden. With its small, colorful blossoms and rich green foliage, lobelia is a popular choice for edging borders, paths, patios, and driveways.
Varieties of Edging Lobelia
There are hundreds of species of lobelia, but the most common varieties used for edging include:
- Blue Cascade Lobelia
- Blue Moon Lobelia
- Cambridge Blue Lobelia
- Riviera Blue Eyes Lobelia
- Regatta Midnight Blue Lobelia
Growing Conditions for Edging Lobelia
Soil: Lobelia prefers slightly acidic soil with good drainage. Avoid planting in soil that is excessively wet or waterlogged.
Sun Exposure: Lobelia performs best in full sun, but can also tolerate partial shade, especially in warmer climates.
Hardiness Zones: Lobelia is a perennial in frost-free regions (USDA Zones 10-11), but is typically grown as an annual in cooler zones.
Planting Edging Lobelia
- Choose a planting site that meets the soil and sun exposure requirements.
- Dig a hole twice the width of the root ball and just as deep.
- Place the lobelia plant in the hole and backfill with soil, tamping down gently to remove any air pockets.
- Water the plant deeply and regularly, especially during the first few weeks after planting.
Caring for Edging Lobelia
Watering: Lobelia requires consistent irrigation throughout the growing season. Water deeply and regularly, especially during hot, dry weather.
Fertilizing: Apply a balanced fertilizer monthly to keep lobelia plants healthy and blooming.
Pruning: Deadheading (removing spent flowers) will encourage lobelia to produce more blooms. In the fall, prune the plants back near to the ground to encourage new growth in the spring.
Problems and Pests
Edging lobelia is generally a low-maintenance plant, but it can be susceptible to a few problems and pests, including:
- Wilting and yellowing: This can be caused by underwatering or poor drainage.
- Foliar diseases: These can be caused by excessive moisture or poor air circulation.
- Aphids and mites: These insects can damage lobelia plants, especially during hot, dry weather.
Additional Tips
- Lobelia is considered to be toxic, so it’s important to wear gloves when handling the plants.
- Lobelia can be grown from seed, but it is often easier to purchase bedding plants in the spring.
- Edging lobelia can be used in hanging baskets and containers, as well as in the ground.
- Lobelia is a great choice for attracting pollinators, such as bees and butterflies.
