When the Gazanie opens its flower heads in the midday sun, life returns to the bed. The daisy family originally comes from Africa, but has established itself very well in our latitudes and is very easy to care for and robust against diseases and pests. With the right care, numerous damage patterns can be largely avoided. Find out now what diseases and pests can occur in Gazanie and what you can do about it effectively or for general prevention.
❶ Powdery mildew - danger to the leaves
A reliable identifier for powdery mildew infestation is a white, reminiscent of flour that spreads on the leaves. The tops of the sheets can be affected as well as the undersides of the sheets. The fungus does not form its spores in the tissue of the plant, but grows directly on the tissue in order to penetrate there later. For this he uses so-called house tories. In order to develop, the fungus needs living tissue. Affected plant parts can therefore be disposed of in the compost heap after their removal, since there are usually no living organisms there.
➔ Tip: Powdery mildew also occurs in dry weather. Therefore one speaks of "fair weather mushroom".
What should I do?
Infested leaves and parts of plants must be removed immediately. A proven home remedy consists of a solution of water and whole milk. This is mixed in a ratio of 8: 1 and the plants are sprayed directly with it. Several applications will be necessary for successful treatment.
The hobby gardener can also do something to prevent the fungus from attacking the gazanie in the first place, namely not to plant the plants too closely in the bed and ensure that they are in a sunny location.
❷ Deformed leaves due to gray mold
The gray mold infestation can also be easily localized. The leaves are covered with a gray coating. The underlying tissue dies over time and striking reddish-brown spots form on the leaves. The leaves begin to shrink from the top and eventually fall off.
➔ Tip: Gray mold occurs particularly frequently in warm and damp weather.
The spores of the fungus also begin to germinate on healthy tissue. However, penetration is only possible in weakened plant tissue.
What should I do?
Gray mold can be controlled in a similar way to powdery mildew. In addition, be careful not to use fertilizers that contain too much nitrogen. An excess supply of nitrogen weakens the plant.
❸ Aphids - unyielding but harmless
Aphid infestation is often attributed to incorrect site conditions. The voracious pests can deform the leaves within a short time, but infestation with aphids is usually harmless, especially if it is recognized early and acted quickly.
What should I do?
A shower with soapy water is a proven remedy for aphids. In the case of mild infestation, a hard water jet is also sufficient. The showering should always be repeated several times. So that the aphids do not fall into the soil and then crawl on the plant again, it is advantageous to cover the soil with foil.
Aphids have some natural predators that do the work for you:
- be crazy
- gall midges
❹ Snails - voracious leaf predators
Especially in spring, when the first delicate leaves appear, snails are on hand to indulge in a wide variety of ornamental and useful plants and cause considerable damage.
What should I do?
You can lie in wait every night to collect the snails because the pests are night owls. However, attaching planting hoods is far more effective and less expensive. These hoods are known from lettuce plants, but flowering plants can also be effectively protected. The hood must be fixed very well in the floor so that there is no loop hole.
Access to the bed is reliably prevented by a snail fence. The small fences have an edge that protrudes to the rear. This edge prevents the snail from accessing the bed and is also completely harmless and environmentally friendly. One may be divided about variants with a built-in stun gun. The snail itself is only deterred and not killed. However, these tools are quite expensive and the function should be limited when it rains.

Avoid illnesses on the Gazanie through proper care
Many damage patterns are due to maintenance errors. If the plants are withered and the leaves are hanging, they have probably been watered too much or too little. Be sure to check the floor and change your casting behavior accordingly. In most cases, the plants recover after some time. However, if the roots rotten due to waterlogging, the plant will probably not be saved. An immediate measure is to completely replace the soil. So the gazanie is taken out of the ground and planted again at a new location.
Overview of care tips for healthy plants
|Location||▶ The location should be in full sun.|
▶ Only when the gazanie is in full sun will it open its flower heads.
▶ If the plants' light requirements are not met, they begin to wither.
|to water||▶ The plants' water requirements are normal.|
▶ Water regularly, but neither too much nor too little.
▶ The plant should not dry out completely and water should not accumulate, as this attacks the sensitive roots and ultimately causes the plant to die.
|Fertilize||▶ The Gazanie has a rather average nutritional requirement.|
▶ To promote flowering, fertilize moderately.
▶ Over-fertilization, especially with nitrogen, should be avoided.
▶ Compost can be mixed in during planting.
▶ Phosphorus-containing fertilizer only needs to be given on very poor soils.
Gazania's health begins with its planting
The foundation stone for healthy and strong plants is laid during planting. So that the young plants do not become victims of night frosts, wait until mid-May, after the ice saints. The Gazanie needs enough light. A plant stand that is too narrow promotes diseases and pests. The distance between the plants should therefore be about 20 centimeters. The floor shouldn't be too heavy. Loosen it well and mix in sand or gravel. This makes the soil more permeable and there is less dreaded waterlogging.
