Instruction1. Sowing: 1. Put seeds into about 40Â° C water for 24 hours. 2. Put seeds into very wet sands for germination.(Generally it take more than 40 days.) 3. Move it into soil after it sprouts. 4. Germination temperature: 20-25 degrees. 5. Germination time: 40 days. 6. Growth optimum temperature: 10-25 degrees. It is generally necessary for sowing the soil loose, breathable, high water holding capacity. The soil is generally used vermiculite, peat, sphagnum, perlite, tree fern and other mixed. Keep seeds stored in a cool, dry place.Damage caused by improper cultivation techniques Growing: Rose on soil not ask for much, just with some humus soil aggregate. Structure can be good training as long as the following three links will make good growth: 1. Rose is drought tolerant plants, but it is afraid floods. It is necessary use non-glazed bonsai pots of soil cultivation. The principle is "do not pour water on it when soil is not dry. Wet it completely when you pour water on soil." 2. Lend a high concentration of fertilizer (especially fertilizers) will result in the death of local rot. 3. All plants need sunlight. Rose like sunshine too. 4. The container in the sun, keep the temperature around 20 degrees. Instruction2. 1.Collect seeds for planting. One way to get seeds is to collect them from established rose bushes. Roses must be left on the bush and allowed to go to seed before harvesting. Seeds are removed from the rose hip, and the outer shell of the hip should be discarded. 2. Test the seeds before planting. Put the seeds in water and discard the seeds that float. Seeds that float may be hallow. The plump, heavier seeds that sink in the water have a better chance of survival. 3. Purchase a flat container for planting the seeds. This will need to fit into your refrigerator. Consult with your gardening center to choose the best flat for your needs. 4. Mix equal parts sand, soil and peat moss. Consult with your gardening center, as they may have a pre-made mixture that you can purchase. You will need enough to fill the flat. 5. Fill the flat with the sand, soil and peat moss mixture. 6. Plant each rose seed one quarter inch deep and space seeds 1 inch apart. 7. Place the flat in the refrigerator; the desired temperature will be about. 4.5 Celsius. Keep in the refrigerator for about 3 months to germinate. 8. Remove the flat from the refrigerator and place in a sunny window, where the room temperature is between18 -21 Celsius . Water lightly. Do not overwater, and do not allow the soil to get overly dry. Transplant the heartiest of seedlings to the garden the following spring.
