(1) 70% garbage soil and 30% river sand.
(2) 60% of dry river mud and 40% of honeycomb briquette are mixed.
(3) 70% of vegetable garden soil, 20% of honeycomb cinder and 0/0% of river sand/kloc.
2. Potting time: after defoliation in early winter or before germination in early spring.
3, water and fertilizer management: potted roses are controlled by limited pot soil, so the requirements for fertilizer and water are strict.
(1) Generally, the convenient and hygienic compound fertilizer is preferred, because the compound fertilizer contains many elements, and the combination of nitrogen, phosphorus and potassium is better. Apply about 20 grams per plant (not too much), deepen the soil around the basin with iron about 10 cm, and then apply fertilizer to cover the soil.
(2) Watering is one of the basic tasks of flower cultivation, but it is often the reason why plants die easily. Water depends on the soil in the basin. Be sure to water it once when it is dry. Too wet can easily lead to rotten roots. Change the soil in the basin every other year, and cut off the roots around the basin bottom when changing the basin, so as to produce more flowers, bigger flowers and more colorful flowers.
4, plastic pruning: usually do not need pruning, pruning old plants to close branches, dead branches, pests and diseases. Roses are in bloom. If they fail, pick them and bloom again, otherwise they will only bloom 1 time.
5, scientific weeding, because the seedlings are small, weeds are easy to grow, so we should do a good job of weeding in real time, so as not to hurt the seedlings without grass. The connected soil is loose. Fertilization is mainly based on organic fertilizer, and topdressing is carried out four times a year as usual. The first watering of livestock manure before and after the festival in Liang Ming is called germination accelerating fertilizer, and the watering is carried out in real time.
In late June and April, the second application of human and animal manure before pregnancy or flower picking will promote more and fuller buds; Apply bio-organic fertilizer in May, and apply overwintering fertilizer in late autumn and early winter to ensure the quiet overwintering of seedlings. Flowering in June, after dormancy in winter, cut off rotten branches, diseased branches and twigs and grow new branches. Careful pest control should be carried out at all stages of field management.
