There are several ways to grow salvia:

  • by dividing the bush,
  • by sowing salvia directly into the ground
  • by sowing salvia into seedlings

Sage is often spread by growing from seed. This method can be realized by sowing seeds directly in the open ground or by growing seedlings at home. Since sage grows slowly when sowing outdoors and therefore blooms late, it is more often pre-growed with seedlings.

Rules: how to grow salvia from seed

At sage planting seeds are planted in late winter or in March. Outdoor planting is carried out in autumn or spring.
It is often the seed method of multiplication of sage is used. Seed spread is possible for all types of salvia.

Seeding method

Sage  is more often spread by seedlings, its landing on seedlings is in February-March month. This method is the most frequently used method.
For planting seeds, you need a container filled with nutritious, light soil. Place the seeds on the soil and lightly sprinkle it with earth. After that, the soil must be moistened and covered with a film.

When a few leaves open, the seedlings will dive. Period when sage is planted is the beginning of spring, the seedlings become strong enough already before summer. After 2-2.5 months after sowing the seeds, the seedlings can be planted in the open air. From the middle of April take pots with seedlings outside for a short time.

Important: The seedlings should receive sufficient moisture. For this purpose you can buy a substrate with hydro granules for germinating seeds. This will help to ensure an even moisture supply for each seedling.

How to plant the seeds directly into the soil

Salvia seeds are sown directly into the soil in winter or early spring. It is possible to sow the seeds from March to June.

  • Prepare the soil and sprinkle it with calcined sand, then place the seeds on top;

  • During the germination period, monitor the substrate humidity.
  • Duration of sage growth – 17-23 days at a temperature of 22-24 ° C.
  • After the appearance and opening of germ leaves, remove the polyethylene.

That’s how you grow salvia in soil.

Salvia spread by dividing the bush

Sage can be spread by bush division in southern regions. This procedure can be carried out at the end of August. The bush is gently dug up and part of the root is removed. The separated part can be used for planting a new separate sage bush.
Do you know this? The salvia leaves are brewed and drunk as tea. This drink is useful for preventing colds, as well as during the cold itself.

How to choose a place for planting

The right place for the plant to live is key to its full growth and development. Sage is very receptive to light, so if you want to grow salva, it is better to plant it in a large, sunny area as it grows quite quickly. If all conditions are fulfilled, you will have a beautiful and full bush in just a few months.
If the soil is too fertile, it will certainly develop well, but this will only apply to leaves and stems. The flowers will be very small and sluggish.

How to choose soil for salvia

In nature, sage grows like a wild plant, so all varieties are not too demanding on the soil composition. The only important point is the lack of close groundwater. Land in the garden or on the garden plot is well suited for sage planting.
For sowing seedlings at home, a universal substrate is an excellent option.
In autumn, it is necessary to dig up a plot of land on which it is planned to plant sage, and also to treat it with fertilizer (phosphorus compositions, humus). When planting sage seeds should take into account the acidity of the soil – it should have an average.

Salvia care

how to care for salvia

If you want to grow salvia, remember, the plant is so unpretentious that it is able to withstand both drought and poor soil, but under such conditions the decorative effect and the level of healing properties decrease. This can be avoided by following the basic rules of sage care.

For leaves to gain healing properties, it is necessary to create favorable conditions for this. Regular watering and loosening from the formation of hard crust, weeding from weeds is mandatory work in the care of sage. Without watering, leaves become stiff and its excess will attract snails, spider mite, thrips and slugs. Thinning young shoots will allow the shrubs to develop well and there will be enough light and air.

In winter, salvia is covered with leaves, straw or branches. The first few years of pruning shoots are carried out in autumn to strengthen the root system, then the procedure is transferred to the spring. Pruning is sanitizing and rejuvenating, leaving only 10 cm of shoot length from the soil surface. In 4-5 years the sage bushes should be replaced and another area should be allocated for planting.  In severe winters, the sage may not survive overwintering, so the plant will have to grow as an annual plant.

How do you recognize sage diseases?

Sage is able to cure diseases of most organs of the human body – the list of its miraculous properties is truly endless. That’s why gardeners are so eager to grow salvia on their plots. However, this unique healing plant is often affected by a wide variety of diseases. So what is the disease of a beautiful sage and how to recognize the sage that has overwhelmed him? It is time to get to know the main symptoms of sage diseases.

Root rot

Most often, this attack affects the underground organs of a young sage, and especially severe damage is caused by tiny shoots. First, the lower parts of the stems become darker and root areas become noticeably thinner. Infected tissues begin to slowly rot, and the above-ground parts of the sage are characterized by stunting, yellowing, as well as fairly rapid fading and dying. If the humidity on the site is increased, the affected vegetation additionally develops an unpleasant spider web of mycelium. Especially intensive development of the disease is observed in case of sharp temperature fluctuations and wet cool weather.

Black root rot

This disease is prevalent almost everywhere where you grow salvia, and it affects plants of all ages – even newly sprouts can not be protected from this disease. Attacked by black root rot, the sage’s roots begin to storm along the entire length, gradually covered by a dark grayish olive and mycelium stain and conidial mushroom spores. Gradually, the infection causes the affected roots to die off.

The leaves of diseased sage go yellow, dry up quickly, while the stems are noticeably thin and characterized by short internodes. In the case of a particularly severe lesion, the sage often dies. The reason of such desease is wet and fairly cool weather, when the thermometer column is stable between sixteen and twenty degrees. Cool, prolonged spring is often marked by a mass defeat of sage.

The hollowness of the root

leaves affected by desease
Unfortunately, it has not been possible to determine the exact cause of this infection at this time. Almost always in places where this attack affects the border between sick and healthy tissues are found mycelium of fungi of the genus Fusarium, numerous harmful bacteria and even weevil larvae. It is quite possible that weevil larvae infiltrating the roots of the weevils may be responsible for the bacteria that cause duplicity.

The sage roots, which are affected by the cavities, thicken noticeably and a cavities filled with a rather loose mass begin to form inside of them. The vascular tissues of salvia gradually break apart, the growth of the plants significantly slows down. Sick plants die very quickly – literally in one or two days.

More often salvia is affected by hollow spaces, and this occurs in the second or third year of its cultivation. Sometimes up to 70% of plants die as a result of this disease.


The most favorable conditions for the development of rust occur at high humidity, moderate temperature conditions and excessively thick landings. Numerous characteristic rust spots are formed on the lower sides of leaf plates as well as on stalks with petioles. If a malignant disease attacks the sage particularly hard, its leaves will start to turn yellow and fall, and the stems will quickly dry out and break with the slightest touch.

That’s why you should follow care rules, if you want to grow stevia.
