Weigela are native to Eastern Asia, namely Japan, Korea and the northern parts of China. While most Weigela will not thrive past USDA Plant Hardiness Zone 5, the Northscaping website says Tango Weigela is hardy all they way down to zone 3. Tango Weigela features purple leaves and red flowers, which bloom for 3 to 4 weeks every June. Cut back the Tango Weigela shrub so it performs well each year.
Deadhead the flowers after Tango Weigela has finished blooming in the summer. Cut off the flowers at the base of the bloom.
Cut off any dead, damaged or diseased wood at the base of the branch to increase the health of the weigela.
Remove any wood more than 3 or 4 years old. The branches will be about 1 1/2 inches thick. Cut the wood off at the base of the plant.
