Rose blossoms more often
"one branch only thanks a Yan, since the spring work is not idle." The four seasons of the rose bloom, competing for beauty, the branches are green and red, especially lovable. Rose flowers like fertile water and plenty of sunshine. If you want to make the rose blossom more, you should master its habits and make great efforts in management.
Rose flowers need more fertilizer, so more fertilizer should be applied and enough organic fertilizer should be applied before sprouting. For potted rose, the pot should be changed once in early spring, the pot soil formula is: loam 5, rotten leaf soil 2, mature dung 2, sand 1, and then add a small amount of vegetable cake, mix it well. From now on, topdressing every 10 to 15 days. Topdressing can be watered with liquid fertilizer made from cake fertilizer and phosphate fertilizer retting. Especially after blooming in May, fertilizer should be applied in time to promote flowering in summer and autumn.
The growing season of rose should be fully exposed to sunlight, and it is advisable to keep sunshine for 8 hours a day. As an indoor ornamental, you should move in before 11:00 and move out before 4 p.m., so as to accept the soft light around noon and prolong the flowering time.
Rose is semi-dormant when it is above 33 ℃, and it is most favorable for growth when the average temperature is 20 ℃ ~ 25 ℃. Therefore, proper shading and multiple water spraying should be carried out in summer. Cooling and moisturizing: in the growing season, it is best to spray water in the morning and afternoon to create a humid environment and promote the growth of flowers and leaves.
After flowering, the rose should be cut below the third compound leaf under the flower to promote strong new branches to bud and blossom as soon as possible. The main points of pruning techniques are: weak short branches first cut, high cut, strong branches then cut, short cut, in order to promote weak and suppress strong, promote its blooming neatly. The pruning length of long branches should not exceed 1 prime 2 to avoid slow germination of axillary buds. In addition, there should not be too many flowers in each stubble, and 3-5 potted roses are suitable, depending on the strength of the plant. Leave too many flowers, nutrients are too scattered, flowers are small and affect the next crop of flowers. Therefore, after sprouting, strong buds should be selected, cut off at 2.5 cm above, and weak buds at the lower part should be removed. After budding, the terminal bud should be selected to remove the leaf axillary bud.
