Neglecting To Disinfect

Not disinfecting tools between cuts, especially when moving between plants, can spread pathogens.

Common Pruning Tips for Oakleaf Geranium

Selective Pruning

Cut back overgrown stems selectively to shape the plant and encourage new growth from the base, focusing on the removal of spindly, weak, or crossing shoots.

Moderate Pruning

Limit pruning to one-third of the plant's size to maintain vigor while encouraging branching for fuller growth.

Sharp Tools

Use sharp and clean pruning shears for clean cuts which promote quicker healing and reduce the risk of disease.

Post-Bloom Pruning

Prune after flowering to remove spent blooms and encourage a second flush of flowers.

Deadheading

Regularly pinch off dead and faded flowers to redirect the plant's energy into producing more blooms and enhancing overall vitality.

Hygienic Practice

Disinfect pruning tools with alcohol or bleach solution between cuts to prevent the spread of disease.

Judicious Thinning

Thin out crowded areas to increase air circulation, which can help reduce the risk of fungal diseases.
