Roses are afraid of waterlogging, waterlogged for a long time, the lower leaves of the branches are easy to yellow, serious waterlogging will make the whole plant die, roses should not be planted too close to the wall, so as to avoid sunlight reflection caused by sunburn.

Roses are harvested at different times, and there are big differences in yield and quality. Usually rose buds should be harvested before opening, that is, the longitudinal diameter of the bud is three times the calyx when harvesting the best, too early to reduce the yield, too late to affect the quality of flowers have opened.

Flowering concentrated period to choose strong full buds picking, other weak buds to be fully open after picking petals. Other sporadic flowers at other times of the year should also be picked when they are fully open.
