How to Repot a Monstera: A Comprehensive Guide
When to Repot a Monstera
Your monstera will need repotting when it becomes rootbound or overgrown. Signs of rootboundness include roots growing out of the drainage holes or appearing to fill the soil surface. An overgrown monstera may have foliage that threatens to tip over the plant or stunted growth. It’s also a good idea to repot a monstera every two years or so to refresh the soil.
Choosing the Right Pot and Potting Mix
Select a pot that is 2-3 inches wider than the current pot. Avoid using pots that are significantly larger, as this can inhibit growth. Ensure the pot has drainage holes to prevent waterlogging. Plastic or ceramic pots are suitable for monstera, while terracotta is not recommended as it dries out the soil too quickly.
Choose a well-draining potting mix specifically designed for aroids like monstera. You can use a standard houseplant mix or blend your own using equal parts peat moss or coco coir, perlite, and orchid bark.
Step-by-Step Repotting Instructions
Materials:
- Gardening gloves (optional)
- Sterilized pruners
- Watering can
- Potting mix
- New plant pot
Instructions:
-
Prepare the New Pot: Fill the new pot about one-third full with fresh potting mix. Do not add rocks or shards to the bottom of the pot, as these can impede drainage.
-
Remove the Monstera from Its Pot: Carefully tip the plant out of its current pot and lift the container away from the root ball. Support the moss pole, if present, to keep it attached to aerial roots.
-
Massage the Root Ball: Gently loosen the roots with your fingers to remove old soil. Inspect the root ball for rot or damage. Remove any soft, black roots using clean, sharp pruners.
-
Plant the Monstera in the New Pot: Place the monstera in the new pot and fill in the area around the root ball with fresh soil. Adjust the soil level to match the previous pot. Leave about one inch of space between the soil surface and the rim of the pot.
-
Direct Aerial Roots Into the Soil: If your monstera has aerial roots, train them back towards the soil. These roots provide support and can absorb additional nutrients.
-
Water Deeply: Water the monstera thoroughly until water runs out of the drainage holes. Allow the soil to drain completely before placing the plant back into a cache pot or drip tray.
-
Let the Monstera Adjust: Return the monstera to its usual location to help it adjust and prevent shock. Avoid fertilizing for at least six weeks after repotting to prevent damage to new roots.
Troubleshooting Repotting Issues
- Droopy Leaves After Repotting: This can be caused by transplant shock or root damage. Water the plant deeply and place it in a warm, humid location. Avoid fertilizing until the plant recovers.
- Yellowing Leaves After Repotting: This may indicate overwatering or nutrient deficiency. Allow the soil to dry out slightly between waterings and fertilize the plant according to the manufacturer’s instructions.
- Root Rot After Repotting: This is caused by excessive moisture. Remove the plant from the pot and inspect the roots. Remove any soft, black roots and repot the plant in fresh, well-draining soil.
