Origin and characteristics

Our protagonist it is a perennial herbaceous plant whose scientific name is Impatiens walleriana. It is popularly known as house joy, home joy, bear ears, balsamina or miramelindo, and is native to East Africa, from Kenya to Mozambique.

It can reach a height of 15 to 60 centimetersand has lanceolate leaves of 3 to 12cm by 2-5cm wide that are arranged in most cases alternately, although they may be opposite. The flowers are 2-5cm in diameter and generally have 5 petals of very different colors: white, orange, pink, red.

What are their cares?

The lilac flower of the Impatiens is very decorative

If you want to have a copy, we recommend that you provide it with the following care:

Location

  • Interior: it has to be in a room where a lot of natural light enters, and where it is placed away from drafts (both cold and warm).
  • Outdoor: full sun. It can also be in semi-shade as long as it receives a minimum of 4 hours of direct light.

Earth

  • Flower pot: universal growing substrate. It can be mixed with 30% perlite if you want to improve drainage, but it is not necessary unless you live in an area where it rains a lot and / or regularly.
  • the garden: it is indifferent as long as it is fertile, and is not very compacted.

Irrigation

The frequency of watering will vary depending on the location, as well as the weather. Taking this into account, we recommend watering when:

  • Interior: 2 times a week in summer and every 7-10 days the rest of the year.
  • Outdoor: 4-5 times a week in summer, and every 5-6 days the rest of the year.

Now, when in doubt, the best thing to do is to check the humidity of the substrate or soil. And for this you can insert a thin wooden stick to the bottom (or as far as you can); If when you remove it you see that a lot of substrate or soil has adhered to it, do not water as this indicates that the humidity is still high.

If you are going to have it in a pot, the most interesting thing however is to weigh it once watered and again after a few days. As the humid substrate / soil weighs more than the dry one, this difference can be very useful to know when to water.

Subscriber

From early spring to late summer (you can also in autumn if you live in an area with a warm or warm-temperate climate) it is necessary to pay the Impatiens walleriana with specific fertilizers for flowering plants. But so that it can grow very well, I advise using, for example, every other month – never mixed -, organic fertilizers such as guano, eggshells, wood ash, or others you can see here!.
