If the plant was purchased in a pot, then it is probably already in a quality potting soil and requires little more than watering and grooming for a while.
If potting a flowering plant to bring indoors or to give as a gift plant, start with a good quality, commercial potting soil. These are usually lighter in weight than topsoil, sterile and pest-free. Many are available with a mild starter fertilizer in the mix.
Select a container with a drainage hole or be prepared to drill holes for drainage if there are none.
Prepare the container by filling with potting soil up to 2” (5cm) from the rim of the planter. Make a small hole in the soil slightly larger than the root ball either by hand or using a trowel. Insert the plant into the hole and press soil firmly around the roots and just covering the root ball. When all the plants are potted, water thoroughly to settle the soil and give plants a good start. Place plant in bright location for best performance.
Repot every 2 years in the same container or in a container slightly larger than the diameter of the roots.
