If you decide to sow yourself, during the sowing and germination period, the most suitable temperature will be between 16 and 25 ºC. But for you to have flowers in summer, you must sow in winter or spring, depending on the weeks of germination of the chosen seeds.
To plant by cuttings (plant division), the ideal temperature is between 18 and 26ºC.
When flowering arrives, the plant demands higher temperatures. Also lack of heat retards growth.
Lack of moisture in the air is one of the biggest causes of indoor plants wilting and dying. Spray the leaves periodically, in this way you will be able to reduce the evaporation of the water and improve the humidity conditions of the environment. But you should know that the flowers should not be sprayed.
In autumn and winter it is not good to water excessively. When the plant is adult you have to water it abundantly with long intervals of time between one watering and another. When the plant is younger you will water less but at shorter intervals.
Take care that the water used to irrigate the plants is not ” hard water “, too calcareous.
The temperature of the irrigation water will be ambient because if it is very cold it can harm the roots.
Depending on the species, the age, the season of the year, and the phase of evolution (growth, maturity…) they will have different needs for fertilizers and food, but a lack of food will mean that the plant does not grow properly and that its flowering is poor, as well as excessive fertilization is also harmful, as it burns the roots.
When you check that the roots fill the pot with your indoor plant, you will need to transplant it to a larger pot, otherwise you will stop flowering, except for some species that bloom better if they are a little compressed (Cintas, Hippeastrum and Clivia, among others). Use a good mix of special substrate for indoor plants.
