Unique bronze color
Broad leaves with wavy edges
Easy to grow

Cryptocoryne undulata Red is a great beginner plant that features long, wavy-edged leaves that are green and reddish-bronze in color. It has a similar appearance to C. wendtii 'Red,' as well as the same easy care requirements. Because this is a medium-sized crypt which grows relatively slowly, it serves as a great low maintenance midground plant. It will thrive under low to medium light and send out runners as it grows.

How to Plant Cryptocoryne Undulata

1. Remove the potted plant from plastic basket, and split the rock wool in half.
2. Carefully remove the plant roots from the rock wool, and make sure to remove all the small, yellow fertilizer balls. Wash off any remaining debris.
3. Use planting tweezers or your fingers to push the roots of the crypt deeply into the substrate until they are completely buried. Pull out the plant slightly so that the crown (i.e., the base of the plant where all the leaves come out) is not covered with substrate.
4. If the plant keeps popping out of the ground, try inserting the plant at an angle or wrap a plant weight at the bottom of the plant to keep it anchored.
5. Make sure to add lots of root tabs if you’re using inert substrate or if your nutrient-rich substrate is depleted.

How to Grow Cryptocoryne Undulata Aquarium Plant

— Cryptocoryne undulata care is very easy, so start by using low to medium lighting between 10-35 PAR.
— Why is my new cryptocoryne melting? Crypt plants are known to experience "crypt melt" where the leaves may melt when suddenly moved to a new environment. To help the plant recover faster and grow new leaves that are accustomed to your water parameters, leave the roots planted in the ground and make sure to provide nutrient-rich planted tank substrate or Easy Root Tabs.
— Why is my Cryptocoryne undulata turning yellow after it was growing so well? Crypt plants absorb lots of nutrients from the ground, so it may be a nutrient deficiency. If the leaves are yellowing and dying after a couple of months, please add more root tabs.
— How to trim Cryptocoryne undulata: If the crypt plant has dying or melting leaves, cut them off at the base of the leaf.

How to Propagate Cryptocoryne Undulata

Crypt plants can reproduce in aquariums by sending out a horizontal runner with a little plantlet at the end or growing little nodes off the side of the original plant. The plantlet will sprout its own leaves and roots that grow into the ground. You can cut off the runner or gently split off the plantlet node from the parent plant. Then the plantlet can be replanted in a different location.
