  • If one day you have to water and there is a forecast of rain or frost, do not water.
  • You must let the substrate or soil dry completely between waterings.
  • If the water does not penetrate the soil when watering, take the pot and put it in a basin with water so that it moistens well.
  • Never water from above, that is, by wetting the leaves, as otherwise, you could cause burns and even rot.

Although the String of Buttons produces seeds, it is rare to see them in cultivation, so it is multiplied more by cuttings. Anyway, let’s see how to proceed in each case:

Seeds in spring-summer

The seeds should be sown in pots with drainage holes filled with a universal growing medium mixed with perlite in equal parts, and covered with a thin layer of previously washed river sand or fine dust. Once watered, it can be placed outside, in semi-shade (but having more light than shade) and keep the substrate always slightly damp.

Thus, if all goes well, they will germinate in about 15 days.

This is the easiest and fastest way to get new plants. You just have to cut a stem, let the wound dry for about a week in semi-shade, and finally, plant it in an individual pot with succulent soil with pumice for example. You can, before that, impregnate the base with rooting hormones, something that will undoubtedly help it to root better but is really not very important since this species tends to root very well.

It will take about two to three weeks for the cuttings to root.

Pests and Diseases

The String of Buttons is a very strong and resistant plant. However, in the rainy season, snails and slugs must be controlled, as they tend to eat their leaves and stems if they are tender.

The plant will only have a disease if it is watered excessively, which will be when the roots are affected by opportunistic fungi. To do this, there is nothing like controlling watering and not wetting leaves or stems.

When to Plant or Repot String of Buttons

The best time to plant or repot String of Buttons is in spring, when the minimum temperature is 15ºC or higher.

If you have it in a pot, move to a larger one each time you see roots coming out through the drainage holes, or when you notice that their growth has stopped. More or less, every 2 years, until it reaches its final size.
