Spirea reevesiana (Spiraea cantoniensis) is also known by the names of Reeves spirea, double bridal wreath and double Reeves. It is a deciduous, or semi-evergreen, shrub that is believed to be indigenous to China and possibly Japan. Spirea reevesiana grows to approximately 3 to 6 feet tall and produces half-inch wide, rose-like flowers that appear in clusters from April through June. Plant spirea reevesiana in early spring and make sure it is provided well-draining soil.
Planting Spirea Reevesiana
Choose a sun-filled planting site for the Spirea reevesiana. Spirea reevesian grows best when planted in full sun, according to floridata.com
Turn over the soil in the planting site down to a depth of between 12 and 18 inches to mix into the soil a 3- to 4-inch layer of organic material. Use peat moss, aged manure or dehydrated compost if the soil is light or sandy. Use perlite or hardwood bark if the soil is sticky or heavy.
Remove any sticks, rocks, roots or weeds from the planting site as you turn over the soil.
Dig a 16-inch wide by 8-inch deep planting hole if you are planting a Spirea reevesiana from a 1-gallon planting pot. Dig a hole 24 inches wide by 14 inches deep if you are planting from a 5-gallon pot. Space each of the planting holes 8 to 10 feet apart, if planting a row of spirea reevesiana.
Cut along the sides of the pot, down to the bottoms using a pair of multi-purpose snips, if planting from a 5-gallon pot. If planting from a 1-gallon pot, give the top of the pot a few quick taps in a downward direction using a hammer or a trowel to slide the pot off the root system.
Plant a Spirea reevesiana into one of the planting holes. Hold the plant vertical in the planting hole. Keep the top of the root system level to the surrounding garden soil. Scoop in soil around the root system, firming it down as you go until you have filled the planting hole full with soil.
Water the Spirea reevesiana with 1 to 2 gallons of water, if you planted the Spirea from a 1-gallon pot. Provide 5 to 6 gallons of water if you planted from a 5-gallon pot.
Caring for Spirea Reevesiana
Spread a 2-inch layer of grass clippings, pine bark or leaf mold for mulch approximately 2 feet in diameter around the Spirea reevesiana. Mulch will prevent weeds from growing and keep precious moisture in.
Water Spirea reevesiana during the summer growing season if supplemental rainfall is less than 1 inch per week. Provide enough water to moisten the soil down to a depth of 6 to 8 inches.
Prune out any dead, broken or weak branches after spring flowering. Snip off dead flowers to encourage a second blooming.
