There is more than one propagation method for Forsythia suspensa, and different propagation methods lead to different growth and development conditions and different flowering periods.If they are propagated by sowing method, the growth and development of seedlings are slow, and they may blossom only after three or four years of maintenance.If it is propagated by cutting method, it may blossom in the same year and in the second year at the latest.However, the number of early blooms is relatively small.
It usually takes more than three years to maintain forsythia to blossom and bear fruit.Even if it can blossom in the early stage, the number of fruits is limited and relatively small.Generally, 8 to 10 years of maintenance will enter the fruitful period, the amount of results will be stable, will become more.Each plant can produce 15-20 kilograms of green forsythia, and begin to make profits.
The failure of Forsythia suspensa to bear fruit may be due to self-pollination.The fruiting rate of self-pollination itself is relatively low, only about 4%.If you want it to bear more fruit, you'd better let it cross-pollinate.When planting, the plants of long style and short style should be planted alternately to improve the fruit setting rate.It may also be improper management, such as lack of nutrients, untimely pruning and so on.During the management period, pruning should be carried out in time to cut off the leggy branches and save nutrient consumption.But also frequent fertilization, nutrient foot growth will naturally be very strong, will promote it better and more results.
