The best time to transplant a rose bush is in early spring or late fall when the plant is dormant. Start by preparing the new location.
• Dig a large enough hole to accommodate the plant.
• Add a good amount of organic compost and some soil amendments to the hole. I recommend a mixture of kelp meal, greensand and rock dust.
• Mix the compost and amendments with the native soil.
Next, prune off some of the top growth to make it easier to handle and dig around the root system. Take care to protect the roots, trunk and branches from damage. Do your best to keep the root ball intact while moving the rose to its new home. Then back-fill the planting site with a mixture of compost and soil. Keep the grafted section of the stem above ground and water immediately. Do NOT add organic fertilizer until you notice signs of new growth.
