Heart-Leaved Bittercress

Heart-Leaved Bittercress prefers consistent moisture and should be watered regularly to maintain soil moisture. It should be watered 2-3 times weekly. In the warmer months, the soil should be kept moist but not overly wet. In the cooler months, water less frequently, about once every 2-3 weeks. If temperatures drop below 40 degrees F (4.4 degrees C) plants should not be watered. In general, provide water when the top layer of soil is dry. Overwatering will increase the risk of root rot and should be avoided.

Heart-Leaved Bittercress is an annual plant that is native to Europe, but is considered an invasive species in many other regions, including parts of North America. The plant requires full sun for optimal growth, about 6 to 8 hours of sunlight per day. Growth can still occur in partial shade, but flowering and seed production will be reduced if the plant is not receiving its optimal light requirements.

Heart-Leaved Bittercress should be pruned annually in late spring after flowering has finished. Pruning should involve removing any dead or diseased stems, along with any that are overly long, crossed, or damaged. The old flower stems can also be removed, as can any seed heads that are present. Pruning should be done carefully, using sharp, clean pruning tools to ensure an even cut and to reduce disease spread. Plants should be pruned back to the crown, leaving 3-4 inches of leaves and stems. It is important to not over prune, as this will stunt the plant's growth and development.
