High Voltage Shrub Rose Care
All Shrub Roses need the same growing conditions. A full sun spot with moderately fertile soil, well drained and consistently moist soil, a neutral soil pH. Fertilizing needs to be done early in the spring as the first leaves emerge. A well balanced, slow release food will provide consistent feeding throughout the summer.
Pruning is very easy with Shrub Roses. Late in the winter or early in the spring cutting out of dead, diseased, dying or diagonal branches will help this shrub to keep its upright shape. A heading cut to shorten the length of branches can also be done to keep the size appropriate to the space or container that High Voltage is growing in. Mulching in the fall with leaves or organic compost will help to protect the shrub's crown and improve the moisture holding capacity of the soil over time. Supplemental irrigation will be needed. Drip irrigation or soaker hoses are the best way to keep water off the leaves. Roses do not like overhead watering.
High Voltage Shrub Rose Spacing
Planting Shrub Roses at a spacing of 30 inches on center will provide for proper air circulation. The mature height of High Voltage Shrub Rose is 3-5 feet and a width of 2-4 feet. Growing High Voltage in a container requires a pot with at least an 18 inch diameter.

?
"Blooms on" tells you which stems produce flowers, which decides when it's safe to prune.
- New Wood: Flowers form on stems that grow this season. Prune in late winter or early spring without losing blooms.
- Old Wood: Flower buds form on last year's stems. Prune right after flowering. Pruning in fall or early spring removes next year's blooms.
- Both New and Old Wood: Blooms on last year's stems and again on new growth, so it flowers even after a hard winter or a mistimed pruning. Prune lightly after the first flush of blooms.
