Getting started -- You can start your plant in a 5 inch (13 cm) pot the first year. If you are in a hotter climate, use an oversized clay pot to keep the roots cooler.
Soil -- It prefers fast draining soil. I use a mix of about 2 parts coir fiber to 3 parts perlite. An alternate mix is 3 parts quality potting soil to 2 parts perlite or coarse horticultural sand. In wet-winter areas, use extra perlite or sand.
For the first 2-3 weeks after repotting, shade it from strong sun. After that, increase the sun exposure slowly to avoid burning.
Water -- While it can tolerate drought, it looks best when the soil is kept evenly moist.
Light -- It enjoys sun, but it might need some afternoon shade in hotter climates if it shows signs of burning.
Climate -- Protect young plants from frost the first couple of years. Mature plants reportedly can take take winter temperatures of 12-16°F (-9 to -11°C). I recommend protecting your plants from frost for at least the first winter or two. Puyas will probably flower soonest if protected from prolonged, hard frosts.
In hot climates, it might be beneficial to shade the pot, perhaps by placing the pot inside a larger pot.
Feeding -- It has moderate fertilizer needs. Feed about every 2-3 months with a general-purpose fertilizer that contains micronutrients.
