â‘ Put seeds into 40Â° C water for 24 hours. â‘¡ Put seeds into very wet sands for germination. ( Generally it take more than 40 days. ) â‘¢ Move it into soil after it sprouts. Germination temperature: 20-25â„ƒ Germination time: 40 days Growth optimum temperature: 10-25 â„ƒ Spacing: 10 inch around between each rose Rose on soil not ask for much, just with some humus soil aggregate structure be good training as long as the following three links will make good growth: Rose is afraid of: â‘ Rose is drought tolerant plants, but it is afraid floods.

Cover seeds with preservative films,and then piercing the films to make several holes. Keep seeds covered in the daytime and uncover it in the night. Take off the preservative films when the seeds are half-germinated. The plant will be in a state of dormancy in summer and the leaves will turn yellow. Begginers should better use sand to cultivate the seeds.although the seeds will grow slower in the sand,the plants will be the most vigorous in the future. If you tend to use other kind of soil, try to use the kind with good water permeability,for example,the clay would not be a good choice.
