Irrigation has to be frequent: about three times a week in summer and 1-2 / week the rest of the year. It is important not to wet the aerial part, that is, leaves, flowers, or stems in order to avoid problems.

If you are going to have it in a pot with a plate underneath, remember to remove the excess water 30 minutes after watering since the roots do not like to have contact with stagnant water, and in fact they can rot easily.


It is advisable to take advantage of and fertilize the plant throughout the flowering season with fertilizers for flowering plants, or with guano (liquid, for sale here!), following the indications specified on the package.


And if we need more copies, we can multiply them sowing their seeds in the seedbed during winter and spring following this step by step:

  1. First, we will fill a seedling tray (for sale here!) with universal substrate or for seedlings.
  2. Then, we will place a maximum of 2 seeds in each socket.
  3. Next, we will cover them with a thin layer (no more than 0,5cm thick) of substrate.
  4. Later, we will water thoroughly with a sprayer, or better, placing the seedbed inside another tray that does not have holes and filling it with water.
  5. Finally, we will place everything outside, in full sun, and we will keep the substrate moist but not waterlogged.

Thus they will germinate in two weeks at a temperature of about 18ºC.
