To achieve success with your new rose seeds you need to do some simple preparation work first.
Rose seeds need to be tricked into thinking that they have past through a cold winter spell. Achieving this will then spark them into life. It is quite magical really when you think about it.
You need to mimic the cold winter environment and the best way to do this is wet a kitchen towel or similar. Put seeds in it fold it over and pop in the fridge for around 2 to 3 weeks. A plastic freezer bag would be good so not to use to much fridge space.
If the paper towels begin to dry add half a teaspoon of water.
If greenhouse growing or propagator growing try to maintain early spring temperatures 70f would be ideal. We always start germinating all seeds in a controlled environment. This way you can plant your rose seeds anytime of the year and whatever the weather. Its up to you when you start them but its nice to know you have options.
Take the seeds from the fridge and plant as follows to ignite the germination process.
This will be achieved by planting in a seed starting tray (inch by inch segmented tray is good and cheap). Use a purpose seed starting mix or mix of your preferred growing media. Just make sure it is sterile and drains well. Keep them warm so they think its sprig time.
Plant the seeds just below the soil line and finely cover. Leave them to germinate just monitoring conditions from time to time.
They need 6 to 7 hours of sun or artificial natural light a day.
When the first two sets of true leaves are visible you can pick out and pot on. If its frosty when they get those leaves hold off planting outside until the winter frosts have passed. Typically, all our seeds can be started any time of year as long as you mimic the seed conditions required to grow.
Happy Growing
