What To Know
- Gently loosen the roots around the edges of the root ball using a fork or your fingers.
- Position the lobelia in the center of the new container, ensuring the top of the root ball is level with the soil surface.
- Fill in around the root ball with the prepared potting mix, gently firming it down to remove any air pockets.
Lobelias, with their vibrant blooms and cascading foliage, are a popular choice for gardeners. To ensure their continued health and beauty, proper repotting is crucial. This comprehensive guide will provide step-by-step instructions on how to repot lobelia, including selecting the right container, preparing the soil, and caring for your repotted plant.
Selecting the Right Container
The size and material of the container you choose will impact your lobelia’s growth. Select a pot that is slightly larger than the current one, allowing for adequate root growth. Choose a container with drainage holes to prevent waterlogging. Clay or terracotta pots are ideal, as they allow for good air circulation and moisture regulation.
Preparing the Soil
Lobelias prefer a well-draining, fertile potting mix. Amend a general-purpose potting mix with perlite or vermiculite to improve drainage and aeration. Do not over-fertilize, as this can burn the roots.
Repotting Steps
1. Water the lobelia: Water the plant thoroughly before repotting to make the soil easier to work with.
2. Loosen the roots: Gently loosen the roots around the edges of the root ball using a fork or your fingers.
3. Remove the plant: Carefully lift the lobelia out of the old container, supporting the root ball with your hands.
4. Inspect the roots: Check the roots for any signs of damage or disease. Remove any damaged or rotten roots.
5. Place in the new container: Position the lobelia in the center of the new container, ensuring the top of the root ball is level with the soil surface.
6. Fill with soil: Fill in around the root ball with the prepared potting mix, gently firming it down to remove any air pockets.
7. Water: Water the lobelia deeply after repotting, allowing the water to soak through the soil.
After Repotting Care
- Keep warm: Place the repotted lobelia in a warm, bright location, away from direct sunlight.
- Water regularly: Keep the soil consistently moist but not waterlogged. Water less frequently as the plant establishes.
- Fertilize: Fertilize the lobelia every few weeks with a balanced liquid fertilizer.
- Monitor growth: Observe the plant for any signs of stress or disease. If necessary, adjust watering or fertilization practices.
Benefits of Repotting Lobelia
- Improved growth: Repotting provides fresh soil and nutrients for the lobelia’s roots, promoting healthy growth.
- Disease prevention: Repotting removes old, compacted soil that can harbor disease-causing pathogens.
- Increased bloom production: Fresh soil and adequate root space encourage abundant blooming.
- Extended lifespan: Proper repotting helps extend the life of your lobelia, ensuring years of enjoyment.
Troubleshooting Common Problems
- Yellowing leaves: This can indicate overwatering, nutrient deficiency, or root rot. Adjust watering and fertilization practices accordingly.
- Leggy growth: Insufficient light or over-fertilization can cause leggy growth. Provide more sunlight or reduce fertilizer application.
- Wilting: This can be caused by underwatering, overwatering, or root damage. Check soil moisture and adjust watering accordingly.
Top Questions Asked
Q: How often should I repot lobelia?
A: Repot lobelia every 1-2 years, or when the roots have become pot-bound.
Q: Can I repot lobelia during the flowering season?
A: It is not recommended to repot lobelia during flowering, as this can disrupt bloom production. Wait until after flowering is complete.
Q: What if my lobelia is root-bound?
A: If the lobelia’s roots have become severely root-bound, you may need to gently trim some of the outermost roots before repotting.
