Propagate begonias

The propagation of begonias is very easy with cuttings. Cut off a stalk from the plant about four inches long. If you want to pull several cuttings at once, then it makes sense to sacrifice an adult plant for them. Then it will be gone, but numerous offspring will sprout again. You should now remove the leaves from the cut off shoot in the lower area so that only two leaves remain at the tip of the shoot. Now you can put the cutting in a prepared container with garden soil.

Make sure that the soil does not have a pH value above 7 and that it is always nice and moist. It should be neutral or slightly acidic. Alternatively, you can grow the cuttings in a darkened water glass and plant them later. In a bright place with room temperature, begonias root extremely quickly, usually within a week. The best time to cut cuttings is after flowering, which is difficult with some species such as ice begonias because they flower as well as ever. But basically, cuttings can be grown all year round.

Leaf cuttings can also be easily pulled without having to clear an entire plant. This works best on species with fleshy leaves. Cut off individual leaves from the mother plant and place them in a prepared planter. It is advisable to put a transparent plastic bag on to increase the humidity. Here are instructions on how to build one Mini greenhouse.

Expert tip: Large specimens of tuberous begonias (Begonia × tuberhybrida) can also be propagated well by dividing the tuber. Dig this up and divide it in half, if it's not too small. Now you can repot them and enjoy two begonias. Spring is ideal for this measure, before you put the overwintered tuber outside again.

Caring for begonias

Begonias turn out to be very grateful and easy-care plants. So you don't have to spend a lot of time with the versatile plants. Begonias even clean themselves by simply dropping dead flowers. There is also no need to prune the begonias. You can only use the secateurs shortly before wintering.

Water begonias properly

Water the tropical begonias regularly, about twice a week. Sometimes it is difficult to find the right balance between too much and too little. This becomes a bit of a challenge, especially on hot days, because waterlogging can quickly lead to root rot. Also keep in mind that plants evaporate more water when there is a lot of wind and therefore need more water under these conditions. You should only water significantly less in winter. With tuberous begonias you can even do without watering after pruning over the winter.

Begonias are not annual, even if they unfortunately often end up on the compost in autumn. Most begonias are actually quite easy to bring over the winter. Tuberous begonias, for example, only need a cool room without frost - it doesn't even have to be light. Most indoor begonias such as eliator begonias, on the other hand, can easily be kept in the room over the winter. Even ice begonias can be hibernated quite well in a bright room at around 16 ° C.
