Climbing roses generally take around 10 to 21 days to sprout, but this can vary depending on the conditions in which it is being grown.
To plant climbing rose seeds, start by soaking the seeds in warm water for 24 hours before planting. Then, fill a seed tray or small pots with a good quality potting mix and plant the seeds at a depth of around 1/4 inch. Water the soil well and cover the tray or pots with plastic wrap or a plastic dome to create a humid environment.
Place the tray or pots in a warm and bright location, but out of direct sunlight. Keep the soil moist but not waterlogged. Once the seedlings have sprouted, remove the plastic covering and move the tray or pots to a location with bright, direct sunlight.
As the seedlings grow, thin them out so that only the strongest ones remain in each pot. When the seedlings are large enough and the weather is warm enough, they can be transplanted into their permanent location in the garden.
NOTE
Climbing rose seeds can be planted in various zones throughout the United States, depending on the specific variety of climbing rose. Most climbing roses thrive in USDA Hardiness Zones 5-9, but some varieties can tolerate colder or hotter temperatures.
