Have you ever wanted to turn one houseplant into ten? Or perhaps you want to give a piece of your favorite plant to a friend as a gift? Propagation is the “magic” process of growing a brand-new plant from a small cutting of an existing one.
While there are many ways to propagate, water propagation is the easiest and most exciting method for beginners because you can actually see the new roots growing through the glass! Here is your step-by-step guide to becoming a plant maker.
Step 1: Identify the “Node” This is the most important part. A node is the little bump on the stem where a leaf or a branch meets the main stalk. This is where the root-growing hormones are concentrated. Roots will only grow from a node.
- What to do: Look for a healthy vine or stem on your plant (Pothos, Philodendron, and Monstera are perfect for this) and locate a node.
Step 2: Make the Cut Using a clean, sharp pair of scissors or a knife, make a clean cut about an inch below the node.
- Pro Tip: Make sure your cutting has at least one or two leaves on it so it can continue to photosynthesize and produce energy while it grows roots.
Step 3: Prepare the Cutting If there are leaves growing directly on the node you plan to submerge, gently remove them. You don’t want leaves sitting underwater, as they will rot and ruin the water quality.
Step 4: Place in Water Fill a clean glass or jar with room-temperature water. Place your cutting inside, ensuring the node is completely submerged but the remaining leaves stay dry above the rim.
- Pro Tip: Use clear glass so you can enjoy the show and keep an eye on the root progress!
Step 5: Wait and Refresh Place your jar in a spot with bright, indirect light. Every 5-7 days, pour out the old water and replace it with fresh water to keep oxygen levels high.
- When is it ready? Once the new roots are at least 2 inches long (usually after 3-4 weeks), your new baby plant is ready to be potted in soil!
Frequently Asked Questions (FAQ)
Can any plant be propagated in water? Most vining plants (Pothos, Monstera, Heartleaf Philodendron) and many soft-stemmed plants (Coleus, Begonias) love water propagation. However, succulents and cacti usually prefer to be propagated directly in soil, as they can rot easily in water.
Why is my cutting turning mushy instead of growing roots? This is usually caused by bacteria in the water or a dirty pair of scissors. Make sure to change the water regularly and always use sterilized tools when taking your cuttings.
