Geum Problems

Geums, popularly grown for their vibrant, colorful blooms, are unfortunately not exempt from issues that can hamper their growth and appearance. Here’s a guide to some common problems with geums and potential solutions:

1. Deformed and Mottled Leaves:

A frequent issue raised by garden enthusiasts is the disfigured appearance of geum leaves, characterized by mottling patterns.

Possible Causes:

• Soil Issues: Geums thrive in well-drained, humus-rich soil. If planted in dense clay soils, they may show signs of distress.
• Viral Infections: Mottled leaves can also be indicative of mosaic viruses.

Solutions:

• Soil Improvement: If the soil is heavy, adding grit can improve drainage, while humus-rich compost will enhance its quality. Regular mulching with compost mixed with fine grit and washed sand post flowering also helps.
• Relocation: Sometimes, simply relocating the plant to a sunnier location can make all the difference. It’s worth noting that plants might need some time to adjust and exhibit proper growth after being moved.
• Virus Management: If a mosaic virus is suspected, one of the best strategies is to remove the plant to prevent it from spreading to other nearby plants. Pinching off affected leaves might provide a temporary solution, but it doesn’t guarantee the virus’s eradication.

2. Stunted Growth and Root Pests:

Some gardeners observe minimal growth in their geums and, upon inspection, find tiny worm-like pests around the roots.

Solutions:

• Root Cleaning: Thoroughly cleaning and trimming the roots before replanting can help. Always inspect plants before purchasing to avoid introducing pests into your garden.

3. Ineffective Blooming:

Some geum varieties might not bloom as expected, leading to disappointment.

Possible Causes:

• Pests: Minute insects can affect the plant’s health, leading to fewer or no blooms.

Solutions:

• Pesticides: Using appropriate pesticides after identifying the pest can help in controlling the infestation.
• Natural Solutions: Simply moving the affected plants to sunnier spots can sometimes help them recover. Cutting off affected leaves and ensuring the plant isn’t overcrowded with other plants might aid in healthy growth.

4. Varietal Resistance:

Certain varieties like Geum borissi ‘Cooky’, ‘Rivale’, or ‘Leonards Variety’ seem less prone to the above-mentioned problems. It might be beneficial to opt for such varieties if you’re in an area prone to the said issues.

5. Proper Feeding:

Weekly watering with tomato food has been shown to boost the health and appearance of geums. This might be especially helpful if your plants are in sheltered sunny positions.

In conclusion, while geums are a stunning addition to any garden, they do come with their own set of challenges. Proper knowledge, combined with patience and timely intervention, can ensure your geums remain a vibrant centerpiece in your outdoor space.
