Common Rhubarb Growing Problems and Solutions: A Visual Guide
From pesky pests to fungal diseases, various problems can plague your rhubarb patch. Recognizing these issues early is crucial for implementing effective control measures. Let’s delve into some common rhubarb growing problems, accompanied by descriptive pictures to aid in identification:
1. Crown Rot: A Silent Threat to Your Rhubarb
Crown rot, a fungal disease, can wreak havoc on your rhubarb plants, often leading to their demise. This silent killer thrives in overly wet and poorly drained soils, attacking the plant’s crown—the point where the roots meet the stalks.
Symptoms:
- Yellowing and wilting leaves, even with adequate watering
- Stunted growth and reduced vigor
- Brown, mushy, and decayed crown tissue
Control and Prevention:
- Improved Drainage: Plant rhubarb in well-drained soil or raised beds to prevent waterlogging.
- Proper Spacing: Ensure adequate air circulation by spacing plants 3-4 feet apart.
- Fungicide Treatment: Apply a copper-based fungicide as a preventive measure during early spring or at the first sign of infection.
2. Leaf Spot Diseases: Marring the Beauty of Your Rhubarb
Leaf spot diseases, primarily caused by fungi, are common rhubarb ailments. These diseases manifest as spots on the leaves, potentially affecting the plant’s overall health and vigor.
Symptoms:
- Small, circular spots on leaves, ranging in color from brown to reddish-brown
- Yellow halos surrounding the spots
- Premature leaf drop in severe cases
Control and Prevention:
- Remove Infected Leaves: Prune and destroy any affected leaves to prevent disease spread.
- Improve Air Circulation: Ensure proper spacing between plants to promote air flow and reduce humidity.
- Fungicide Application: Apply a fungicide specifically designed for leaf spot diseases, following the instructions carefully.
3. Rhubarb Curculio: A Pest with a Taste for Rhubarb
The rhubarb curculio, a type of snout beetle, can cause significant damage to rhubarb stalks, impacting both yield and quality.
Symptoms:
- Small, round holes in rhubarb stalks
- Scarring and distortion of stalks
- Presence of small, grayish-brown beetles with elongated snouts
Control and Prevention:
- Handpicking: Regularly inspect plants and handpick adult beetles, dropping them into soapy water.
- Remove Plant Debris: Clear away fallen leaves and stalks to eliminate overwintering sites for the pest.
- Insecticide Application: If necessary, apply a registered insecticide to control severe infestations.
