Creeping Jenny Southern Blight

Southern Blight, a fungal disease can kill Creeping Jenny. This fungus attacks the plant when it is weakened by shade, excess moisture, or physical damage.

Southern blight is very common in southern soils. Do you see webby stuff between leaves and stem and the soil?

This webby stuff is called hyphae. Hyphae are like the roots of a fungus. This fungus decomposes the stems of your Creeping Jenny.

You’ll also see tiny brown beads scattered everywhere on your plant. These are called Sclerotia and help the fungus to stay alive during winter.

How to treat Southern Blight

There’s no fungicide that can effectively deal with Southern Blight. The best way is to prevent its growth in the first place.

Do not overwater the creeper. Keep the soil wet if needed but not soggy. Make sure the soil has good drainage properties.

Tip: If the soil is waterlogged, add some gritty sand or PermaTill to the soil.

If the plant is already infected, dispose of the dead creeper. Dig up the soil and bury the fungus and its remnants(Sclerotia).

You may add new soil to the affected area and grow plants again safely.
