Mul candles are actually pretty sturdy plants. However, aphids and root rot can cause them problems. But there are effective methods of combating both problems.Mullein is resistant to most diseases and pests. When the plants move in front of them, grow poorly and hardly bloom, the soil is often too moist or contains too many nutrients. Root rot can occur under these conditions. The leaves and flowers are sometimes attacked by aphids. They can fight you however with biological means.
Recognize and combat aphids on mullein
Rolled up, withered leaves and sticky leaf surfaces are usually signs of aphid infestation. The problem: Due to the honeydew, which you see as a sticky surface, it is also possible for soot thickening fungi to settle. In addition, the small green aphids multiply rapidly. Therefore, it is important that you fight an infestation quickly.
Strengthen the plants by pouring your candles with diluted nettle or garlic. But please do not pour too much, because the plants prefer a mostly dry soil! If many aphids have already settled on the plants, it helps to spray the candles with soapy water. Instead of soapy water, you can also use water with a few drops of tea tree oil.
Furthermore, natural enemies such as Ladybug useful. They feed on aphids and put an end to the haunting. Lacewing and ear clowns are also good aphids. In an ecologically balanced garden, natural enemies usually set themselves up. But you can also help by building a dwelling for earwigs.
And this is how it's done:
Fill a flower pot with plenty of straw and hang it upside down on a nearby branch. Fix the straw by placing two flexible, thin branches crosswise in the opening.
Wrong location and soil lead to root rot
In a dry, well-drained and nutrient-poor soil, the mullein stays healthy. The undemanding plant feels really comfortable in a sunny environment. It needs little water and is hardly susceptible to disease. With a heavy, compacted soil, on the other hand, irrigation water or rainwater can not drain properly. At the root ball then a fungus can trigger the root rot. They recognize the disease because the Mullein barely grows, not or only little flowers and the leaves wither. In addition, a foul smell penetrates from the ground.
There is no antidote to root rot. Remove the entire plant and place new mullein in a more suitable location. If the rot has not yet progressed too far, you can dig up the mullein, remove the affected roots, and reuse the plant elsewhere with a dry, sandy soil. Often, the plants regenerate by themselves. If the soil is heavy, you can mix in sand and small pebbles to create good starting conditions.
Older mullein may also lose growth. Simply remove the plants from the bed. Through the self-propagation of the seed in your garden always new mullein. The plants rejuvenate by themselves.
