large coneflower

It's best to water large coneflower (Rudbeckia maxima) deeply and infrequently. Generally, a deep, thorough watering once or twice a week is sufficient, depending on rainfall and the weather. In the spring or summer when it's warm and dry, larger Rudbeckia maxima might need to be watered once every 5 to 7 days. When temperatures are cooler and there's more rain, it's usually necessary to water only once a week. To determine if your large coneflower needs to be watered, poke your finger about 2 inches into the soil. If it feels dry, water your plant. When you water, apply water until it starts to come out of the drainage holes in the bottom of the container. Don't overwater, as this can cause the plant to rot.

Large Coneflower needs at least 6 hours of sunlight a day for optimum growth. It prefers full sun but will tolerate some light shade. The best time of day to give your plant light is between 10 am and 6 pm with the sun highest in the sky during the middle. This will ensure that your plants get the optimal amount of sunlight across the spectrum of sunlight that it requires. Water late in the day when the sun is setting to allow the ground to absorb the water before the night creeps in.

The best time to prune large coneflower (Rudbeckia maxima) is in early spring, before the plant begins to bloom. Pruning should involve removing damaged and dead branches, and cutting stems back to the desired shape and size. Generally, 1-third to 1-half of the tallest stems should be removed. Don't remove more than 1-half of the stems at once, as this can weaken the plant and cause it to become misshapen. Although large coneflower can be pruned during any time of year, it should be done lightly moving forward. Prune when necessary, such as to shape the plant, but avoid removing too much material.
