It’s very interesting plant rosemary in the garden or in a pot at home. This plant, like many other aromatic plants, does not require much maintenance. It grows in all types of soil, preferably arid, dry, not very sandy and permeable, adapting very well to poor soils.

It should not be watered too much. Its natural climate is the Mediterranean climate, and although it grows on the coasts, it adapts well to other climates, as long as they are not very extreme, such as temperate or temperate-warm climates, as well as climates dry.



For rosemary to grow well and without problems, it needs a series of minimum conditions for its proper development. The basic conditions and care of rosemary are mainly light, temperature and humidity:

  • auspicious light: Potted rosemary needs direct sun, but it’s best to place it in a spot that doesn’t get too much sun or shade. Too much sun can cause leaf burn, and lack of it can affect its healthy development.
  • Optimal temperature: Rosemary can adapt to hot or cold temperatures, but it is also true that it does not tolerate frost or very hot days. In both cases, the plant can suffer and die.
  • Humidity: This plant is native to the Mediterranean region, so it does not need excessive watering to be able to develop normally.


It is a plant that grows best outdoors, as it needs direct sunlight, as we mentioned. Despite this, if it is not possible to have it outside, it is preferable that it be in a place where it receives as many hours of sunshine as possible.

If you have the plant outdoors and the temperature drops a lot in the winter, especially at night, you might consider moving the potted rosemary indoors and bringing it out when the environmental conditions improve. .


Through the rosemary cuttings we can propagate the harvest. This is the best way we have to reproduce the plant. We will help each other homemade roots natural like lentil rooting or the willow rooting. We have already seen in other articles how to prepare them, in addition to how can we use them.

Aromatics, as a rule, are cut after flowering in summer, but for greater efficiency it can be done in autumn. In the following video we explain step by step how to proceed in this case:


You have to water the rosemary when you see that when you put your finger in the substrate the first 5 cm are dry. Since it is a moisture-sensitive herb, and even more so if it is a potted rosemary. If planted in the ground, it is best to water between 1 and 3 times a week, always depending on the local climate.

If you have a drip irrigation system, this would be a better option than watering with a hose, as the water you supply is more controlled.


There are several ways to cut the rosemary which we can apply as we see fit:

Training size

is type of size This is done when the rosemary is already large with several branches. If you don’t want it to get very tall, it’s time to prune it. You have to watch the plant carefully and remove the branches that are dry. You have to think of the shape you want it to have, be it round, square or whatever comes to mind and proceed with the cutting.

  • Rosemary is sensitive, no more than a third of the plant should be pruned in one sitting. If you need more, we’ll do it later.
  • As we said, the first thing to do is to remove the dry branches, which are in poor condition or broken.
  • Then we take the scissors and thinking about the shape we want to give it, we start cutting the healthy branches. For example those that are too long.
  • One sizing tip is to step back and take a good look to confirm that the shape you are giving it is correct.
  • If you have worked well with the rosemary and it is 2 meters tall, the ideal would be to prune annually or every 2 years.

Rejuvenation or cleansing pruning

This pruning should be done in the warm months at least a month or a month and a half before winter and frost. The ideal is in early spring.

  • With the scissors well disinfected, we begin to cut the dry or old branches at the base of the plant.
  • We gradually cut the branch to prevent it from breaking and injuring the rosemary.
  • You have to look at the branches that are inside because they are the ones that are generally in the worst condition.
  • It may be that you haven’t pruned in a long time and all the branches are in bad shape, so you should do a training pruning.
  • Remember not to remove more than 1/3 of the plant or damage could lead to death.
  • A well-ventilated plant indoors will be healthy because if there are many branches, pests are more likely to appear.

This plant should be pruned when we see dry or yellow leaves and flowers or when it is very full of pests.
