Giant Spear Lily
Getting started -- A 2-4 quart pot should hold it for at least 6 months. Don't transplant it to too large of a pot. Use a well-draining soil mix. A typical mix is 2 parts potting soil to 1 part perlite. An alternate mix is equal parts of coir fiber and perlite.
Long-term care: Aim to keep the soil evenly moist most of the time. Don't let the soil dry out completely, but avoid keeping it fully saturated. You can monitor the soil moisture with a moisture meter probe.
Feeding -- Feed every 2 months using a general purpose fertilizer at 1/2 the recommended dose. Unlike some Australian plants, this one can handle phosphorous, but use a fertilizer with an equal or greater amount of nitrogen ("N") than phosphorous ("P"). Careful not to overfeed your plant.
The Giant Spear Lily is said to handle 5 or 10 degrees of frost, but it's best to give them overhead protection from frost, especially the first 5 years. In hotter areas, some afternoon shade may be needed, especially if you notice leaf burn.
