Temperature: 60-80 F

Humidity: medium to high; avoid drafty areas

Water: Water when the top 2-4” of potting mix has dried. Plants tend to get root bound in summer months, using water quickly.

Repotting: Repot every 1-2 years into a slightly larger container (1-2” increased diameter or depth). Use a well-drained potting mix such as bark-based or coir-based. If not available to you, use a general purpose potting mix.

Fertilizing: Either…

1. Water Application: Incorporate fertilizer into your watering cycle once per month March through September. Dilute an all purpose fertilizer (20-20-20) by half OR use your favorite fertilizer rated for houseplant use in your water.

2. Slow Release: Incorporate slow release fertilizer pellets into the top inch of potting soil every 6 months. Apply the rate indicated for indoor plants on the label. If no recommendation for houseplants is present, apply 1/4 to 1/2 the listed rate.
