- Plant Away: Gently loosen the root ball of your plant and place it in the pot.
- Add More Soil: Add more potting mix around your plant, leaving about an inch of space from the rim of the pot.

Watering Tips
The best way to know if your plant is thirsty is to stick your finger about an inch into the soil. If it feels dry, it's time to water. Be sure not to let your plant sit in a saucer full of drainage water, as this can lead to root rot.
Product Tips
- Time to Repot: To keep your long-term container plants happy, we recommend repotting them with fresh potting mix every year or two. This gives them fresh nutrients and helps prevent the soil from getting compacted.
- Keep Them Fed: After about two months, your plants will be ready for a meal. Start a regular feeding routine with a Miracle-Gro Organic Plant Food to keep them growing strong.
