How to care for lisianthus?

All flowers are very decorative, but when looking for something very special, there is often no choice but to visit several nurseries or take a look at the catalog of online stores. And it is that, to enjoy the beauty of plants such as lisianthus, it is well worth it.

These are plants of tropical origin that are grown as annuals, as they are unfortunately very sensitive to cold. But, despite everything, they are so beautiful that we are going to explain how to care for lisianthus.

What are lisianthus like?

Lisianthus, whose scientific name is Eustoma grandiflorum, is an annual plant native to the southern part of the United States and northern Mexico. It grows forming a rosette of leaves that develops on a stem up to 50cm long. Its beautiful flowers are large, 3-4cm in diameter, and in colors that can be white, pink or blue.

Its growth is very fast; Not in vain, they only spend a few months germinating, growing, developing, flowering and bearing fruit.

Lisianthus cultivation

If you would like to have lisianthus in your garden or patio, here is how to take care of it:


To get them to grow healthy and strong, they need to be protected from direct sun. They can also be indoors, in a very bright room. Its acceptable temperature range is between 35ºC and 20ºC.

Soil or substrate

As they can be grown both in pots and in the garden, you should know that:

  • If it is potted, we recommend mixing universal substrate (on sale here ) with 20-30% perlite or similar. In addition, if you want to drain even better put a first layer of arlita or volcanic clay thus, you will see that the water on to the water will come out faster.
  • If it is in the garden, the soil must also have very good drainage and be fertile, that is, rich in nutrients. As they are small plants, if the one you have in your garden does not meet these characteristics, do not worry: make a planting hole of about 40 x 40cm, cover its sides with shading mesh, and then fill it with the mixture of substrates mentioned before. Or you can even plant it first in a slightly large pot, about 20cm in diameter, and without taking it out of there put it inside the hole.


Frequent, but avoiding waterlogging. It should be watered 3 or 4 times a week in summer, and 1-2 every six days the rest of the year. If you have a plate underneath, you should remove the excess water within ten minutes of having watered since otherwise the roots could rot easily.

Also, you should avoid wetting the leaves and flowers in order to keep them healthy.

Lisianthus multiply by seed in spring, following this step by step:

  1. First, put the seeds in a glass of water for about 30 minutes. After that time, keep only those that have sunk, as the others will probably not be viable (although you always have the option of sowing them in a separate seedbed).
  2. Then, fill a pot, a seedling tray, or any other seedbed with universal substrate and water.
  3. Then place the seeds on the surface so that they are a little apart from each other. If you sow them in seedling trays, put a maximum of two in each socket.
  4. Then cover them with a thin layer of substrate.
  5. Finally, moisten the top layer of the earth with a spray filled with water, and place the seedbed outside, in semi-shade.

This way they will germinate in about 20 to 30 days.


From spring to the end of summer it is advisable to fertilize with a universal fertilizer (sold here ) or a fertilizer for flowering plants (sold here ) following the instructions specified on the product packaging.

Planting or transplanting time

In spring, when the minimum temperature is at least 15 degrees Celsius.


Lisianthus do not resist frost ; in fact, once they bloom and, if they are lucky, bear fruit, they begin to dry out. You can extend their life a bit by removing the flowers as soon as they begin to wilt.
