Due to their attractive appearance, rapid growth and ease of care, oxalis are widely used in floriculture as indoor and garden crops. They do not impose special requirements on illumination, temperature and air humidity, are little affected by diseases and pests, tolerate room conditions well, and in summer even heat-loving forms successfully grow in open ground or on a balcony.
Flower care room sour at home
When growing oxalis at home, it is provided with bright but diffused lighting, best of all on windows with an eastern orientation. Despite the fact that the flower tolerates penumbra well, with a lack of lighting it stretches, shrinks and loses its decorative effect. The open sun is even worse for the plant, which can leave burns on tender leaves, so the bushes must be shaded on the southern windows.
The temperature range favorable for growth is from 12-18 °C in winter to 20-25 °C in spring and summer. With the onset of steady heat, a flowerpot with a flower can be placed in the garden or on the balcony.
The culture is not demanding on the humidity of the surrounding air, during active growth it can be sprayed with boiled water, but such procedures are not carried out in winter and autumn.
Proper watering is an important condition for quality care. At home, oxalis require soil with a sufficient amount of moisture, and at the same time, the nodules of most species do not tolerate waterlogging, as a result of which they easily rot. In spring and summer, the flower is watered abundantly, while not allowing excess water to stagnate in a pot. In autumn and winter, the intensity of watering is reduced, keeping the soil in a slightly damp state.
For top dressing, which is carried out from April to August with a frequency of 2-3 weeks, you can use any complex mineral fertilizer at a dosage half that indicated on the package. In order for nutrients to penetrate faster to the roots, it is recommended to loosen the soil around the bush.
The rest period in most species is short, lasting 1-1.5 months. Plants usually just stop growing, although there are varieties that drop their leaves completely. For all room sours, care at this time consists in providing a cool content and limiting watering, lighting remains at the same level.
After a dormant period, in the spring, it is recommended to transplant, for young specimens – annually, for adults – at intervals of 3-4 years. It is best to use wide pots, placing 5-10 bulbs or nodules in them at the same time, previously cleaned of old roots and rhizomes. The culture is undemanding to soils; any universal soil for home flowers sold in stores with a loose consistency and a slightly acidic or neutral reaction is quite suitable for it. You can make up the soil mixture yourself, using, for example, one part of sand, leaf and humus soil, three parts of peat. Note that with excessively nutritious soil, the bush actively grows foliage, but blooms worse. It is important that there is a drainage hole at the bottom of the pot and a sufficient layer of expanded clay, this will prevent rotting of the root system.
Interestingly, with a sufficient level of lighting, oxalis can bloom at any time of the year. To do this, she needs to artificially create a dormant period: after flowering, transfer to a cool place and water less. Under such conditions, the plant is kept for about a month, after which they are transplanted, they begin to actively water, feed, and after a month flowers bloom again on the bushes.
In nature, the culture is propagated by seeds; for indoor and garden species, vegetative propagation methods are preferred. The most common is the division of rhizomes, as well as the use of numerous daughter tubers or bulbs formed around the central root. The latter are carefully separated and planted in open ground or flowerpots at a shallow depth. At home, a pot with plantings is placed in a cool place, and after germination, put on a lighted windowsill. Leaf and stem cuttings are also used to propagate oxalis, which take root well in water. Roots appear in 15-20 days, after which young plants are planted, placing several pieces in one pot. Rooting in wet sand is also possible using mini-greenhouses in the form of a glass jar or plastic bottle. The most favorable time for breeding is spring or autumn.
How to care for sour in the garden
Winter-hardy rhizomatous species grown in open ground are extremely unpretentious in care. Oxalis flowers belonging to this group can grow both in the open sun and in full shade under trees and bushes, do not require fertile soil and top dressing, grow well and do not suffer from diseases and pests. One of the few culture requirements is loose, permeable, acidic soil without stagnant water, and the need for abundant watering in hot weather, which is best done in the morning and evening. Of the features of cultivation, one can note the uncontrolled growth of rhizomatous oxalis, which scatter seeds over long distances.
Most heat-loving indoor species can also be planted in the garden. To do this, the bulbs are placed in open ground at the beginning of May with an interval of 20-30 cm, the plantings are covered with a film, which is regularly opened during the day for airing and watering, and removed after the appearance of sprouts. In addition, flowerpots with pre-planted bushes can be taken outside, as well as bulbs can be planted in tubs with large plants. How to care for sour further is described in the section on indoor species.
