How to grow fragrant rosemary at home?
Planting in the pot
First of all, determine what method you want to get a rosemary shrub - the simplest is to plant a finished cutting that can be bought at a garden store or on the market. At home, this procedure is carried out in early March, so that rosemary will reach maturity by mid-summer and be able to please you with healthy and strong sprigs that can be used in cooking and household.
In addition, there is cultivation from seeds, which begins at the end of February - a similar method is somewhat more complicated, because of the ten seeds of rosemary, only 1-2 grow up.
To grow rosemary, you need to find the right composition of the soil - you can buy a special substrate in the store, and if you want to make it at home, you will need:
- one piece of peat;
- one piece of humus;
- one part of fine river sand;
- two parts of leafy ground;
- two parts of turf, cleared of roots.
The ground for rosemary should be only slightly damp — at home you can achieve this by spraying a minimal amount of water on it with a hand spray gun. Avoid also the use of acidic soils - otherwise rosemary dies quickly, not reaching normal development.
To grow such a useful plant should be in a pot of medium size, the diameter of which is approximately 15-16 centimeters. To grow large rosemary, special care is not needed - just try to keep the sprout until its full maturity at a temperature approximately equal to 15-20 degrees. In the future, the temperature range is significantly expanded, which allows you to set the pot at home on the windowsill without the need for constant monitoring.
How to get a healthy perennial plant?
For rosemary cultivation to give good results, you need to follow only a few simple rules.
At home, try to maintain for an adult plant the temperature corresponding to the range from 15 to 25 degrees. In the autumn, rosemary can be grown on a balcony, where the minimum temperature is about 11-12 degrees.
If you keep rosemary on the window sill, try to open the window less often in order not to create sudden temperature changes, under the influence of which the plant may lose some of its leaves.
It is better to install a house plant on a southern window-sill, as in natural conditions it receives a lot of natural sunlight. Special light filters are not required - however, in the winter you can at least once a day include phytolamp above it to avoid the lack of ultraviolet radiation necessary to ensure the normal level of leaf health.
The largest bushes in the cold season can be transferred to special greenhouses - for example, rosemary can be grown on a balcony or loggia, provided that the temperature specified above is maintained there.
Care also includes the provision of light humidity - if your home does not have a new heating system and monolithic walls, you can perform this procedure about once a week. Otherwise, with a large aridity, it is possible to grow large rosemary in a pot on a windowsill only by increasing the spraying frequency twice.
Watering is carried out about once every three days - at home, proper care requires that the soil was only slightly wet most of the time. However, when the temperature inside the house exceeds 25 degrees, rosemary requires abundant watering every day.
If white patches appear on rosemary, which spread throughout most of the leaves and stems, you are trying to grow it in conditions of excessively high humidity. Care in such cases includes the installation of plants on the windowsill with good heating by the sun's rays, as well as reducing watering to a minimum level. From the plaque, which is a downy powdery mildew, you can get rid of with the help of a fungicide, however, this plant should be excluded from human consumption.
Growing can also be accompanied by the appearance of a pest such as a spider mite. In this case, the air, on the contrary, is excessively dry - it is required to spray rosemary with insecticide, and then repeat the spraying with clean water for a week every other day.
At home, large bushes can grow excessively and give numerous shoots. If you want to get a large and healthy rosemary, cultivation includes an annual transplant with the removal of overgrown single roots and the mentioned shoots. In order to provide the plant with the appropriate care, during transplantation also completely change the soil and apply a small amount of potash fertilizers.
If you want to grow a new rosemary plant at home, using the one you already have, you can use a fairly simple breeding technique. One-year shoots from July to September can be used to form cuttings, which are grown according to the scheme outlined above. In addition, you can also use other methods - in particular, the division of the bush with a part of the rhizome.
The popular breeding method for rosemary is the collection and sowing of seeds - however, they germinate badly enough, which forces them to be patient for even one healthy shrub. Rosemary can be planted in the summer in the open ground - however, it is worth doing it around the beginning and middle of May to provide the ideal temperature to adapt the root system, as well as normal humidity.
