watering
Water should be applied once every 5-7 days, depending on the weather. Water deeply to ensure the entire root system is getting moisture. In hot and humid conditions, water every 3-4 days. In dry and arid conditions, water more often and increase the amount of water with each application. Soil should be kept moist but not soggy. Overwatering can be just as damaging as not enough so make sure the soil is allowed to dry out a bit between waterings.
sunlight
White snakeroot thrives in full sunlight and grows best in partially-shaded areas. For optimum growth, white snakeroot should receive 6 to 8 hours of direct sunlight every day.
pruning
White snakeroot should be pruned back to the ground in late winter to early spring. Pruning will create an overall pleasing shape, safeguard against diseases, and encourage new blooms. When pruning, use sharp anvil pruners to avoid crushing stems, and remove all dead and diseased branches. Remove any shoots that are growing too close to the center of the plant to promote air circulation. Make all cuts near a leaf node or bud, and never leave a stub. Finally, be sure not to remove more than 1/3 of the plant’s overall structure when pruning.
