When receiving the Lemon Button Fern, do not repot immediately but wait at least 6-12 months or if the roots are beginning to get crowded and growing through the drainage holes. They prefer to be a little crowded in their pot.
Repot in the spring, using a 2 inches bigger pot to give the roots room to spread.
Place a piece of screening at the bottom of the container over the drainage hole to secure the soil and allow to drain. Use a rich, well-draining indoor potting mix amended with 25% compost and to help with fertility.
Water your plant in the old pot before transferring over and let sit an hour.
Add well-draining potting soil amended with peat moss and perlite to the bottom to elevate the root ball. Lift the plant and release the roots against the existing planter. Use a clean knife or garden trowel to wedge between the pot and the soil to loosen.
Inspect the root ball. Notice if there are any dead or rotting roots and trim off with sterile pruners. If the plant is rootbound, cut through the roots to alleviate continued encircling.
Ensure the plant is sitting about 1 inch below the edge of the pot to avoid water spillage. Add more soil and backfill around the sides by tamping down. Fill up to the soil line but not over.
Water thoroughly, and unlike its cousins, they like to have a bit drier soil conditions. If settling occurs, add more soil.
Water well to dampen the soil and let drain.
