Generally, the original rock flower is sown and propagated in March and April, and it emerges about 6- 15 days after sowing. At 3 months, the seedlings can grow to the size of mung beans. By the end of 10, the plant can reach 12 mm by increasing the light amount and time. Every year, the original stone flower will shed its skin and grow new plants in it.
How to break the dormancy of the original stone flower? We found that the decisive factor causing the dormancy of raw stone flowers is temperature, followed by light. To break the dormancy of raw stone flowers, we must start from this aspect. Practice shows that as long as the temperature is kept at 15-28 degrees in late spring and early autumn, the annual seedlings are shaded by 70% with less nitrogen fertilizer, the illumination time is shortened to 5-7 hours per day, and the temperature difference between day and night is 8- 10 degrees, the original rock flower can grow all year round.
At ordinary times, the temperature at home is maintained at 15~28℃ all the year round, and raw stone flowers can grow all year round.
How to speed up the growth of raw stone flowers? Under the condition that the temperature can be controlled, the raw stone flowers will crack the old leaves for the first time in the sunny windowsill or closed balcony with heating in the northern region after winter and before the Spring Festival. At this time, fertilizer should be properly applied, and the amount of water should be slightly increased. Don't cover it, because ultraviolet rays have been discounted when sunlight passes through the glass. Loosen the culture medium once every half month to avoid damaging the root system. It is not until early April that the new leaves will grow to the size of the old ones.
What soil do you choose for potted stone flowers? Like other succulents, raw stone flowers are still mainly cultivated in soil. Overall grasp two points: loose and breathable, rich in organic matter. Clivia soil in the market can be selected, and 1/3 perlite or vermiculite can be added as the cultivation substrate, and a small amount of calcium superphosphate can be added at the same time. Although it is not special soil for meat, it is still quite practical.
When planting raw stone flowers, put a broken pot with a thickness of 3-4cm, add fine bricks with a thickness of 2cm, put some decomposed sheep manure or oil cakes, then place the mixed culture soil at a distance of 65438 0 cm from the edge of the pot, slightly compact it, carefully loosen the roots of raw stone flower seedlings with a jack such as a bamboo stick, and squeeze and bury them from all sides to the joint between the roots and stems. It doesn't matter if individual plants shake slightly.
What fertilizer is used for raw stone flowers? Through the practice of many flower friends, decomposed sheep manure is the best base fertilizer for raw stone flowers. But there is little sheep dung, so let's be practical. You can choose a mature potash fertilizer, add a small amount of phosphorus and calcium, and supplement trace elements and nitrogen fertilizer, which can effectively promote the growth of plant roots. Plant roots grow well, leaves are full and shiny, and the number of cracked heads increases, which is easy to blossom and bear fruit.
You can also choose to spray fertilizer on the leaves, and the commonly used foliage flower nutrient solution can be used. When new leaves open old leaves, apply urea directly, 6-8 plants are large and 3-4 plants are small, so as to promote the rapid growth of new leaves. However, plants must be prevented from rotting due to accumulated water in new cracks. Fertilization and watering should be carried out simultaneously. Try to apply thin fertilizer as often as possible, and don't be impatient, so as not to cause fertilizer damage.
