The leaves of some Aukube varieties have such strong yellow mottles that they appear more yellow than green to the eye. It's not about her. Rather, it's about yellow specimens that represent an unhe althy existence. What's going on?
Why does my Aukube have yellow leaves?
If an Aukube has yellow leaves, the cause can be frost damage, drought, heat, sunburn or, more rarely, diseases and pests. To save the plant, you should cut back the affected leaves and shoots and optimize the living conditions.
Why does my Aukube have yellow leaves?
An evergreen aucuba (Aucuba japonica), also called gold leaf, Japanese golden orange, or Japanese laurel, gets yellow leaves when it has to grow as a houseplant or in the garden underunfavorable living conditions. Which “yellow dye” was at work must be explicitly checked for each affected plant.
- Frost Damage
- Heat and dryness
- Sunburn
- rare diseases and pests
When does frost damage occur on the Aukube and what to do about it?
From -15 °C it becomes critical, but otherwise the Aukube doesn't want to freeze for long, even though it is hardy and, depending on the species, temperatures range from -5 °C to - Can survive 15 °C. Yellow and soon black leaves are symptoms of frost damage. Cut back affected parts of the plant in spring. This can easily be done even in old wood, because Aukube is cut-friendly. Even after radical cuts, it sprouts well. Protect your plant better next winter. If it's in a bucket, it's better to overwinter indoors.
How do drought and heat cause yellow leaves on the Aukube?
Dryness and heat cause a lot of moisture to evaporate from the soil, but also from the leaves. ThenAukube's water supply suffers If the water shortage lasts longer, more and more leaves turn yellow. If the Aukube is in direct sun, its leaves, especially the top ones, can even get sunburnt. Water more often on such days so that the soil remains slightly moist. Place potted plants in partial shade immediately. Warm wintering with little light is also harmful. 5 to 8 °C is ideal.
Are yellow leaves on the Aukube always a cause for concern?
Not all leaves of an aukube that exchange their green for yellow are a request to take immediate rescue action. Because there may well be a harmless explanation for them. As already mentioned, leaves of some varieties, such as Aukube Variegata or Aukube Crotonifolia, are naturally heavily speckled with yellow. In addition, some leaves on older plants turn yellow every year, despite the best care. These are the oldest specimens and are usually located at the very bottom of the plant. You can cut them off or let them fall off on their own.
Tip
In this country, only plant Aukube in mild regions
The Aukube can tolerate a lot of frost. But in harsh areas their survival is at risk, or at least they lose some of their shoots. Only plant them in protected places in mild regions. Otherwise, prefer pot culture. Then it can overwinter in a cool place in the house and there will be no yellow leaves.
