The Bubikopf (Soleirolia) is a nettle plant that is only cultivated in this country as a houseplant or in a pot. Even though it can tolerate cool temperatures, it is not winter hardy. What you need to consider when overwintering a bob haircut.
Is the Bubikopf winter hardy?
The Bubikopf (Soleirolia) is not hardy and can tolerate temperatures between 5 and 25 degrees. In winter it should be kept indoors at 12 to 18 degrees and with sufficient humidity. Outside it can survive light frost for a short time if it is protected and insulated.
Bubikopf is not hardy
The bobbed hair can tolerate a wide range of temperatures. They can be between 25 and 5 degrees. However, the houseplant is not winter-hardy, so it should not be exposed to cold temperatures for several days.
The ideal temperatures in the house are between 18 and 25 degrees during the growing phase. In winter, the bobbed hair should be kept cooler. If it stays in the room all year round, you will have to water it more often.
The humidity should be sufficiently high because the plant evaporates a lot of moisture through the leaves. But don't spray it with water. Even when watering, you should never wet the leaves directly.
Bubikopf overwinter in the house frost-free
In winter, the Bubikopf prefers a cooler location, but where it needs to be as bright as possible. Stairwells, entrance areas or cool winter gardens are well suited. The temperatures in winter are ideally between 12 and 18 degrees.
Do not place the bobbed hair directly next to heaters or other heat sources. To increase the humidity, especially in winter, place bowls of water near the plants.
In winter, water is slightly less, especially if the Bubikopf is wintered cool and not too brightly.
Bubikopf overwintering outside in the bucket
If you live in a very mild area or can offer a sheltered spot, you can also overwinter Bubikopf outside. You need to move it to a location where temperatures do not drop below freezing. However, it can also survive very light frost for a short time.
- Find a protected location
- Place the pot on an insulating surface
- Cover the pot with burlap
- cover with brushwood
Place the pot on an insulating surface, cover the pot with sackcloth and cover the bobbed head with pine branches or brushwood.
Tip
Sometimes it is claimed that Bubikopf is hardy. In this case it is confused with the blue bobhead (Isotoma fluviatilis), a perennial plant. The two species are not related.
