Caring for the moose

We have seen the best known species, but now we have to know what care we must give them so that they are well. So let’s get to it:


These plants they must be in sunny areas. Don’t be afraid that it will hit them directly – they need it! In this sense, they are like sunflowers: when they lack light … their stems fall, they stop producing flowers, and they weaken. For this reason, it is not a good idea to have them indoors either.


  • Flower pot: you can put a substrate for plants, the universal one, although we recommend mixing it with 30% perlite in case it doesn’t have one. Hollyhocks cannot stand waterlogging.
  • the garden: the earth, as long as the water drains well, will be correct.


During spring and especially in summer you have to water from time to time. We have said that we must avoid waterlogging, but it is also important that the soil does not remain dry for too long. Therefore, if you have doubts, there is nothing better than checking the humidity with a wooden stick for example.

If you have it in a pot, do not put a plate under it to prevent the water from stagnating.


Alcea are herbaceous plants

In full growth and flowering season it is highly advisable to fertilize them with a liquid fertilizer for flowering plants, like this one they sell here!. Follow the instructions for use to know what dose to take, and how often to apply it.


The Alcea multiply by seeds in spring-summer. These you have to sow them preferably in a seedling tray (for sale here!), since by having different alveoli you will be able to control much better how many germinate and when.

Fill it with substrate for seedlings (you can get it by clicking on this link), put a maximum of 2 seeds in each socket, and cover them with a thin layer of soil. Then, put the seedling in the sun, and keep the substrate moist.

Thus, will germinate in about ten days. When they do, leave the seedlings in that seedbed until the roots come out of the drainage holes, at which point you can plant them in pots or in the garden.


With clean scissors you can remove the dried stems and the flowers that are wilting.


It depends on the species, but in general they resist moderate frosts of up to -12ºC.
