watering

Watering a giant rhubarb plant (Gunnera manicata) will depend on the climate in which it is grown and the size of the plant itself. In general, it is best to water the plant deeply and frequently during active growth. During a typical growing season, giant rhubarb should be watered about once per week, allowing the top few inches of soil to dry out slightly between waterings. In areas of extreme heat or drought, you may need to increase the frequency of watering, and during winter months when the plant is in its dormant stage, it is only necessary to water occasionally. When watering your giant rhubarb, be sure to water at the base of the plant and avoid getting the leaves wet.

sunlight

Giant rhubarb, or Gunnera manicata, prefers bright, indirect light. In the northern hemisphere, this means providing the plant with roughly 6 hours of sunlight during the warmer months. In the winter, the sun's angle is lower and the days shorter, so the plant will need less sunlight - around 3 to 4 hours of direct sunlight. During the summer months, the plant can even benefit from a few hours of full sunlight each day. It is important to protect Giant Rhubarb from extreme hot temperatures and direct sunlight as this can damage the leaves.

pruning

Giant rhubarb (Gunnera manicata) is a species of plant known for its large, tropical-like leaves and clusters of red to pink blooms. Pruning this plant is important for keeping it healthy and looking its best. Giant rhubarb should be pruned in late winter or early spring, just before new growth appears. During this time, you should remove any dead, diseased, or damaged leaves and stems. Cut away any stems that are growing in an undesirable direction. You can also prune back some of the older, overgrown foliage, as well as remove any dead flowers. This will open up the plant and allow more light and air to circulate within it. Keep in mind that this plant is a dramatic and fast-growing 1, so if pruning back too much, you may significantly stunt its growth. Prune only what is necessary.
