To revive wilting lobelia in a hanging basket, especially due to extreme heat or neglect, submerge the entire basket into a large bucket or container of water for an hour. This method allows the dried-out compost to fully rehydrate, providing essential moisture back to the plant's roots.
Lobelia, with its delicate flowers and trailing habit, is a popular choice for hanging baskets, but it can quickly wilt if not properly cared for, particularly during hot weather.
Immediate Rescue Steps
If you notice your lobelia looking droopy or completely wilted, follow these steps for effective revival:
- Prepare the Water Bath: Find a large bucket, basin, or container that is wide and deep enough to fully immerse your hanging basket. Fill it with water at room temperature.
- Submerge the Basket: Carefully lower your entire hanging basket into the water. Ensure that the compost (soil) level is completely covered by water. You might need to hold it down initially as the dry compost will make the basket float.
- Soak for an Hour: Leave the basket submerged for at least one hour. This duration allows the growing medium to thoroughly absorb water, rehydrating the root ball which is crucial for recovery. You will notice bubbles rising as the trapped air escapes and water fills the voids.
- Drain Excess Water: After an hour, lift the basket out of the water. Allow any excess water to drain away completely before rehanging it. Lobelia dislikes sitting in soggy conditions, which can lead to root rot.
Long-Term Care and Prevention
Once revived, ongoing care is vital to prevent future wilting and keep your lobelia thriving throughout the season.
Watering Best Practices
- Daily Checks: Hanging baskets, especially those exposed to sun and wind, dry out very quickly. Check your lobelia daily, sometimes twice a day in hot, dry, or windy conditions.
- Feel the Weight: A good indicator of dryness is the weight of the basket. A dry basket feels much lighter than a well-watered one.
- Water Until it Drips: Water thoroughly until water starts to drain from the bottom of the basket. This ensures water reaches all the roots.
Feeding Your Lobelia
- Regular Feeding: Lobelia in hanging baskets benefits from regular feeding. Use a balanced liquid fertilizer every 1-2 weeks, as nutrients in the limited soil volume can quickly deplete.
- Follow Directions: Always follow the dilution instructions on the fertilizer product to avoid over-fertilizing, which can burn the roots.
Pruning for Denser Growth
- Addressing Leggy Growth: If your lobelia, or other companion plants like petunias or trailing geraniums, start to look straggly or "leggy," don't hesitate to cut them back. This encourages new, denser growth and more prolific flowering.
- Pinching Back: Regularly pinching back the tips of young lobelia plants can promote a bushier, more compact shape from the start.
Ideal Environment
- Sunlight: Lobelia generally prefers partial shade, especially in hotter climates, as direct afternoon sun can lead to quicker drying out and stress. Morning sun is usually ideal.
- Air Circulation: Ensure good air circulation around your hanging basket to prevent fungal issues and help with temperature regulation.
By implementing these care strategies, you can enjoy vibrant, healthy lobelia in your hanging baskets all season long.
| Issue | Symptom | Solution | Prevention |
|---|---|---|---|
| Wilting | Drooping leaves/flowers | Submerge basket in water for an hour | Consistent daily watering |
| Leggy Growth | Sparse, stretched stems | Cut back straggly stems to encourage new growth | Regular pinching of tips |
| Yellowing Leaves | Nutrient deficiency | Apply balanced liquid fertilizer | Fortnightly feeding during growing season |
| Browning Edges | Over-watering/Under-watering | Adjust watering schedule, ensure drainage | Check soil moisture before watering |
