While the plant can tolerate partial shade, it thrives best in areas with full sun exposure. Look for a spot in your pond where the plant can receive at least 6 hours of direct sunlight each day.

Another crucial factor to consider is water depth. Shield Pennywort can grow in both shallow and deep water, but it requires at least 10cm of water depth to ensure optimal growth. 

Preparing the Planting Area

Before planting Shield Pennywort, it's important to prepare the planting area to give the plant the best chance of success. Start by removing any existing weeds, debris, or algae from the designated area. This will prevent competition for nutrients and ensure that the plant has a clean environment to grow in.

If your pond has a muddy or sandy bottom, consider adding a layer of aquatic soil or gravel to provide stability for the plant's roots.
