Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Big-leaved Marshweed thrives in consistently moist soil, mimicking its natural marshy habitat. Water thoroughly whenever the top centimeter of soil begins to feel dry.
Avoid letting the substrate completely dry out, as this can stress the plant. For aquatic setups, ensure the water level is maintained.
Prune to maintain desired shape and size, and to encourage bushier growth. Pinch back the tips of stems regularly. Remove any yellowing or dead foliage promptly to improve air circulation and plant health.
This also helps prevent legginess.
Propagate easily through stem cuttings. Take cuttings of about 10-15 cm from healthy stems, remove lower leaves, and place them in moist soil or water. Roots will typically form within a few weeks.
Once established, they can be transplanted.
Repot Big-leaved Marshweed annually or biannually, preferably in spring, when it becomes root-bound. Choose a pot that is slightly larger than the current one.
Use a well-draining potting mix, often with added perlite or sand to improve drainage, especially if keeping it in a pot.
