This may not be the quickest method of propagation, but it’s possible.
To get hold of the seeds, the rose hips should be left on the plant to fully ripen. Come autumn they can be cut off and cleaned, before cutting them in half to remove the seeds. Mix a little diluted bleach into a container and add the seeds – this will kill off any bacteria and fungus. The seeds can now be rinsed before the next part of the process which is stratification.
Stratification refers to a period of cold, moist storage to aid germination. Placing the seeds in the fridge for 6-10 weeks can give them a bit of encouragement to sprout when they are planted out. Place the seeds on a paper towel and moisten it with water and peroxide to prevent mould growing.
Alternatively, plant the seeds in a tray full of peat-free potting mix and placing the tray in a plastic bag and place this in the fridge instead. Keeping the tray in a plastic bag will help to keep the compost moist.
To sprout the seeds, remove them from the fridge and place in a warm environment. Once they’ve sprouted, they can be potted up into individual pots. Use a spoon or other clean tools to transplant so the roots aren’t touched.
