How to grow rosemary indoors

Until recently, rosemary was considered an exotic plant and an unusual seasoning for our cuisine, but recently it has become increasingly popular.

Not everyone knows that rosemary can be grown in an apartment, and not only in gardens, kitchen gardens, and other open areas, and sometimes it takes root better in a house because it loves warmth. In this article, we will tell you in detail how to grow such an unusual, fragrant, and very healthy herb right on your windowsill.

What you need to know about rosemary

The shrub is divided into two main types - prostrate rosemary and ordinary (medicinal). Indoor cultivation lends itself only to the type of ordinary rosemary (it is also called fragrant). Prostrate belongs to the wild species and is more often used as an ornamental shrub to decorate gardens.

The medicinal species, in turn, is divided into several varieties, which have some not-so-significant differences among themselves, but they all take root well at home.
The plant grown in a pot can be used as a spice by adding it to dishes. It also has healing properties, decoctions, and tinctures for various diseases made from it. The shrub purifies the air of microbes, emits a fragrant aroma, and according to ancient beliefs, protects the house from evil forces.

Growing rosemary at home on the windowsill: preparation

Pot selection

An ordinary flower pot is suitable for growing grass, but not plastic, but clay. Some also use wooden boxes, but in this case, the wood must have high moisture resistance.

The dishes need not be small, because rosemary has long, sweeping roots. There must be a drainage hole at the bottom of the container.

The soil

The plant loves loose slightly alkaline or neutral soils. You can buy a ready-made substrate in the store or cook it yourself: mix garden soil, compost, and humus in equal parts.

Put some pebbles on the bottom of the pot to create good drainage. The soil should be poured into a container 7-10 days before planting and fertilized with a nutrient mixture.

Location selection

Rosemary loves warmth and sunshine. In a poorly lit room, he can quickly die. Pots are recommended to be placed on the windowsill of a room located on the south side.

If it is impossible to create conditions for high-quality natural lighting, then be sure to install a fluorescent lamp near the pot.

Planting rosemary in a pot

There are two ways to propagate a plant at home: cuttings and seeds. The best time for this is April or May. In winter, rosemary should not be planted, it is unlikely that it will take root.

Consider each method of cultivation in detail.

Growing rosemary from seeds on a windowsill

This is the most time-consuming process, but some still like to grow herbs from scratch. Rosemary seeds can be purchased at any flower or garden store. They are very small and require preliminary preparation before planting.
  • 3-4 days before planting, the seeds are laid out in moist gauze and folded into several layers. Gauze is moistened daily through a spray bottle.
  • After a few days, the seeds are evenly sown in the ground and sprinkled on top with a thin layer of earth.
  • The soil is abundantly moistened (it is advisable to use a spray gun so as not to wash off the top layer of the earth) and cover with a film, having made several holes in it for ventilation.
  • Pots are cleaned in a warm place with a stable temperature of + 16-20ºC. You need to moisten the soil every day, but not much.
  • As soon as sprouts appear on the surface (usually this happens after 3-4 weeks), the film is removed and the pots are rearranged to a lighted place.
When the sprouts get stronger, they can be planted in other pots, one seedling at a time. It is not recommended to leave many seedlings in one pot, otherwise, they will suffocate each other with their root system.

Growing in an apartment from seeds does not always give a positive result, sometimes the sprouts do not germinate or germinate in very small quantities.

There can be many reasons for the dissimilarity of rosemary seeds:
  • bad soil,
  • excessive watering or, conversely, lack of moisture,
  • the too low temperature in the atmosphere,
  • poor quality seeds.
Don't be discouraged if you don't get seedlings, you can always try again or use a different method of propagating the fragrant shrub.

Growing rosemary in an apartment with cuttings

Cuttings are an easier way to propagate a plant. The soil for cuttings is prepared in the same way as for seeds.

To get cuttings, you can simply pick a few tops from the shoots of a bush or buy a bunch of greens in a supermarket.
Remove the lower leaves from the branches and put them in clean water so that they take root. This may take a couple of weeks, do not forget to refresh the water every 3-4 days.

As soon as the roots have appeared, the cutting is ready for planting: make a small depression in the soil and plant a twig, burying the root with earth. Moisten the substrate and expose the pot to a warm, well-lit area.

You can plant the cutting immediately, deepening the lower part of the branch into the soil by 3-4 cm. In this case, you need to cut off the top of the shoot so that the plant uses its strength to form roots.

Propagation of rosemary by cuttings at home is usually more successful, especially if a branch with roots is planted.

About varieties

As mentioned above, ordinary medicinal rosemary is divided into several varieties that differ in flowering (flower color may be different), leaf shade, size, and character.

The following varieties of rosemary are best suited for growing in apartment conditions:
  • "Lavender",
  • "Tenderness", growing from seeds that give the most successful results,
  • varieties "Rosinka" and "Roseus" also take root in apartments quite well.
But in general, there are no restrictions on varieties, you can try to grow any shrub from the common rosemary species.

Care for rosemary in a pot

In the summer, it is recommended to keep the greens in sunlight in a well-ventilated area, but not in a draft.

The soil in the pot should not be allowed to dry out, but waterlogging is also dangerous for the root system of the bush. In summer, constant soil moisture should be 50-60%. On average, during the hot period, the bush is watered once every 2 days.

If the temperature exceeds + 25ºC, then every day you need to spray the green shoots with water from a spray bottle. Once a month, the plants are fertilized with organic and mineral fertilizers.

How to water rosemary at home in winter

In winter, the plant requires different care. Watering is reduced to 2 times a week, and top dressing is carried out once every 1.5 months. shrubs provide additional artificial lighting for 5-6 hours a day.

It is desirable that the temperature in the room where the pots are located is not higher than + 14 ° C and not lower than + 5 ° C.

Air humidity is very important. If the plant is kept indoors with high humidity, it can get sick. It is necessary to ensure air circulation in the room where the containers with rosemary are located.

If the wintering was successful, in late April, or early May, rosemary begins to bloom with small, but beautiful and fragrant purple, lilac, pink or white flowers.

After wintering, room care is continued in this way: the pots are again exposed to the sun's rays, and the frequency of fertilizing and watering is increased.
