- What are the signs that my rhododendron needs pruning?
Look for signs like overgrowth, dead branches, or a lack of blooms. If your plant is becoming too dense or is blocking sunlight to other plants, it’s time for a trim. Regularly checking your rhododendron helps keep it healthy and vibrant.
- How can I improve drainage for my rhododendrons?
To improve drainage, consider planting rhododendrons on a slight slope or amending the soil with sand or perlite. Creating raised beds can also help prevent water from pooling around the roots, reducing the risk of root rot.
- What type of fertilizer should I use for rhododendrons?
Use a fertilizer specifically formulated for acid-loving plants, such as those containing slow-release nitrogen. Apply it in early spring to give your rhododendrons the nutrients they need for healthy growth and blooming.
- Can rhododendrons be grown in pots?
Absolutely! Rhododendrons can thrive in pots as long as they have enough space and proper drainage. Use a suitable potting mix that maintains acidity and ensure the pot has drainage holes to prevent water buildup.
