Weigela is a group of flowering deciduous shrubs that is originally from East Asia. Although the foliage on the original weigela (Weigela florida) was bland, the many cultivars of weigla today are anything but boring. Some varieties offer striking variegated foliage and brilliantly colored flowers ranging from shades of red to pink.
Choose a planting site for the weigela shrubs that is in full sun to partial shade. For best flowering, choose a site that is in full sun.
Loosen a 2-foot-square section of soil in the planting site for each weigela shrub you intend to plant. Each section should be between 4 and 8 feet apart, depending on the type of weigela you are planting. Use a shovel or a garden fork to loosen the soil to a depth of approximately 10 to 12 inches. Remove weeds, roots, sticks and rocks as you turn over the soil.
Lay out a 3- to 4-inch layer of peat moss, ground pine bark, dehydrated compost or similar material over the topsoil in each of the planting sites. This is to help improve the fertility and drainage of the soil. Weigela is adaptable to most soil types, but it does require good drainage and fairly fertile soil for best growth.
Dig a planting hole in each of the planting sites that is about three times the width of the planting pot and approximately its same depth.
Cut along the sides of the planting pot, beginning at a drain-hole, using a pair of all-purpose snips. Continue cutting around the entire pot until you can peel back the plastic far enough to remove the weigela.
Roughen up the root system of the weiglea if it appears matted or ensnared. Spray off about 1-inch of soil all the way around the root system using a stream of water. If there are any twisted or entangled roots, cut them off.
Plant the weigela shrub into the planting hole. Hold the weigela level and straight in the planting hole while you scoop in soil to secure the plant in place. Back fill the planting hole with soil until it is about two-thirds full. Then fill the planting hole full with water. As soon as the water has settled back, fill the rest of the hole with soil.
