Sind das zwei getrennte Anlagen? Wenn ja, sollte ich sie in zwei Töpfe aufteilen?

Usually they’re individual plants, and no you don’t need to separate them, Ficus can live together pretty well and in pretty tight situations, that said if you want two individual plants go for it, they need to be straightened up anyway even if you leave them together unless you like that look…

You can separate them if you like, or repot them together.

If you decide to separate or divide them – l was nervous the first few times I divided plants, so I’m putting the process I use, in case it’s helpful:

Have your new pot(s) and soil ready. Put several inches of soil in the bottom of the pot(s), have additional fill soil at hand, and have a watering can or hose or sink ready.

Take a slim knife or even a butter knife and slide it down the inside wall of the pot until the tip of the knife hits the bottom of pot, then lightly saw up and down going all the way around the inner wall to loosen the roots and dirt.

Grasp both stems together right at their bases, lift straight up with a slight wiggling motion until the whole root system and plant come out of the pot.

Looking at the roots may help you decide whether to separate them. If all you see from the sides and bottom are crowded roots (not much dirt visible), you’ll want to either separate them or repot them into a larger pot.

If you decide to separate them: I use a cheap bread knife and saw off the bottom inch of the flat bottom of the roots (I find it promotes growth, not everybody agrees if it’s necessary or not).

Then slide the bread knife between the two stems and just saw the root ball in half. Set each half on the soil in the bottom of the new pots, hold the stem center and straight upright, and fill in the gap between the roots and the wall of the pot.

Use your fingers to gently compress the fill soil. Water the plant lightly all the way around. The fill soil will settle a bit. Use more soil to fill around the plant, again, then water it thoroughly.

Best of luck with your little ficus buddies! 🤗

Not always but it seems to me, variegated plants are suggested to be less vigorous.

Because the white parts do not contain the green pigment chlorophyll, is the whole plant is less enthusiastic?

can separate if you would like to. repotting together should not cause any issue in my opinion. just give more room if you want to keep them together.

Separating is optional and a personal preference. In general, plants prefer not to complete for space and do better separated. Probably go smaller with the pot sizes if splitting.
