Transplanting -- Move it to a pot about 1 gallon in size, which will hold it for a few months. You can then move it to its permanent home - about 5-10 gallons, or into the ground in suitable areas.
Soil -- Bomarea likes a fertile, well-draining soil. A typical mix is 3 parts potting soil to 2 parts perlite or pumice rock. Don't add lime, since Bomarea likes slightly acid soil.
Repot gently to avoid damaging the roots. Watering before transplanting will help keep the soil ball from breaking apart. For the first week after repotting, shade it from prolonged sun, and don't give liquid fertilizer.
Climate -- Bomarea is happiest above 40-45 degrees. The tubers can take several degrees of frost, but it may kill the leaves. It's best to protect the plant from all frost, especially the first 2 years.
It warmer climates, don't plant it where heat can collect, like against a sunny wall. Mulch the plant to keep the roots cool and moist. Avoid using a black pot, which can overheat the roots. Even better, keep the pot shaded.
Light -- Bomarea likes about a half a day of sun. It can take more sun in cool, coastal areas. It should be given some protection from strong afternoon sun, especially in warmer areas.
Watering -- Bomarea likes the soil kept evenly moist.. but don't keep it constantly saturated either. If your tap water is "hard" or high in minerals, i recommend using bottled water or rain water.
Fertilizing -- During periods of active growth, feed every 2-3 months with an all-purpose fertilizer that contains micronutrients.
It's normal for an older shoot to occasionally turn yellow and die throughout the year, but if it seems excessive, it could be from not enough fertilizer (nitrogen) or under-watering.
Up and away -- Bomarea likes to climb, so give it something to twine itself around, like a trellis, fence, or another plant. It should ideally be under 1 inch thick (3 cm), so the shoots can twine around it. A 6 foot (2 meter) trellis should work, although a taller one is better if possible. If the shoots grow too long, wrap them down and around your trellis. Don't trim the shoots, since the flowers appear from the growing tips.
The tubers should not be dug up, as this may damage the plant.
Pests to watch for -- Snails and slugs can be a problem in prone areas. Keep an eye out for other bugs too.
