Cotyledon

Life form Succulent
Family Crassulaceae

Ease of cultivation Easy for growing a plant
The size Depending on the species up to 30-70 cm in height and width
Growth rate Low
Lifespan 3-5 years, the plant requires rejuvenation.
Temperature In the summer: room, up to + 80,6 ° F, in winter it is desirable not more than +59 ° F, not below +41 ° F, otherwise it should move the plant away from the radiators.
Humidity Low. The plant is indifferent to the level of humidity.
Lighting Bright sun, in the winter fit the windows of the south and south-east orientation. In the summer, shading is necessary, because When the light is too bright, the leaves can turn red and burns appear on them. For better flowering, it is desirable, starting from August, to provide the plant with a duration of illumination not more than 9 hours (during the rest of the day you can cover the plant with a dark cap).
The soil Suitable shop soil for succulents with a small addition of sand. For a mixture of own preparation, take:   3 parts of coarse sand or perlite, 2 parts turf ground, 2 parts of humus (leaf earth), 2 parts peat. The soil should not be heavy, good drainage is necessary.
Watering The top layer of soil between waterings in the summer should dry up well. Water from April to September 1 time a week, from November to January – do not water, February-March 1-2 times a month with soft water. Excess water from the pan should be drained.
Fertilizer During growth, every 2-3 weeks, feed fertilizer for cacti in a half dose.
Reproduction It multiplies easily in the spring with apical cuttings 8-10 cm in length and leaves, which should be taken in the spring – in the beginning of summer from the branches of the current growth. Can be treated with heteroauxin. Root in peat, sand under polyethylene, peridetically aired at a temperature of 68-71,6 ° F. Sand from time to time spray. Rooted cuttings are transplanted into separate pots and placed in conditions of bright scattered light. The tips of the shoots are pricked after the appearance of the third pair of leaves. Also propagate with a separate sheet.Can be propagated by seeds that are sown in February in a mixture of leaf land and sand (the seeds should not be sprinkled with earth, it can be lightly sprinkled with sand) and germinated at a temperature of 53,6-57,2 ° F. The plates are covered with glass or polyethylene, the substrate is periodically sprayed and ventilated. Fresh seeds germinate in 1-2 weeks. Shoots dive and expose to light. The second pick is held in early summer. Watered poorly, it is preferable to spray.
Bloom Cotyledon round-leaved blooms in July – August, wavy – in March – June. Tubular flowers of various colors, often collected in paniculate inflorescences.
Transfer Transplanted annually in March until the pot reaches a diameter of 15 cm. After that, you can only change the top layer of soil in the pot. To isolate neck cotyledon moisture around it can pour a layer of pea gravel.
Features of care Sometimes cotyledons in summer can discard leaves, in this case they are kept in dryness. Prior to cotyledon should be less touch, so that the mealy plaque is not erased from the leaves. Extruded plants are cut off, the upper part can be rooted, the lower part of the stem can further give new shoots.
Difficulties It is affected by spider mites, mealybugs, scutes, aphids.On the leaves, rot may appear, if water gets on them. The rot of the root system and the base of the stem can arise from a constant overflow. Flowering plants are prone to powdery mildew (moldy and blackened areas on the leaves). If the lower leaves turn yellow and fall off, most often this is the natural aging process of the plant. However, the lower leaves can turn yellow and dry up due to insufficient soil moisture. Leaves fade, the stems and sinuses of the leaves turn black and rotten as a result of the appearance of the fungus, which develops due to over-moistening of the soil. Plants are strongly stretched because of a lack of light. Slow growth of a plant can be associated with a lack of nutrition. Sometimes a plant withers for no apparent reason because of the development of the rootbug, which can be seen only when transplanting the plant.
