How To Take Care Of Rose Plant In A Pot. A miniature rose plant needs a minimum of 10 inches of depth for a plant about 18 inches tall. Put a layer of gravel at the base of pots and place pots on feet.
Warning Keep the desert rose away from children and pets. When planting miniature container roses for the soil in the container I use a good bagged garden soil for outdoor use. Portulaca doesnt require much care at all Ro says.
Taller containers are ideal since rose roots grow deep.
If there are no drainage holes drill several 38-inch 95 ml holes in the bottom of the rose containers for drainage and place a layer of 34-inch 19 cm gravel in the bottom to help provide the drainage area. Most container roses are bought and planted in the spring or summer months though can be planted at any time throughout the year so make sure you fill your hole with water before planting and allow it to drain away to keep the ground moist. Shrub roses for example get too big and often will not thrive in a container. If transferring from a nursery pot best planted from autumn to spring or planting as a bare root best planted in early winter fill container with a loam-based acid-right mix specifically formulated for roses.
