Hippeastrum bulb

While Hippeastrum is in flower, it will require more water. You should check it daily, but water it only when the soil is dry. The bulbs are prone to rotting and should be kept somewhat dry. They are usually sold loose, so when you first purchase one, it will probably have no leaves or flowers, and very little root mass. Pick one that is firm and heavy, with greenish-white flesh and thin brown outside layers, like an onion. Be sure to avoid anything that feels squishy or dried out.

Planting the bulb   Bulb planted one third above ground
Pack the bulb firmly, but not too tightly,
as the roots need air as well as water.
  Leave about one third of the bulb above ground.

When you get it home, plant it in a pot that is only slightly larger than the bulb itself. A half to a full inch of space around the bulb should be sufficient; Hippeastrum flowers more profusely when pot-bound. Be sure to use a pot that has holes in the bottom, and avoid soil mixes with a lot of peat moss in them. Hippeastrum needs a more granular soil to encourage drainage and prevent the roots from rotting. Pack it firmly, but not too tightly, as the roots need air as well as water. Leave about one third of the bulb above ground. Then place it near a window where it will get some sun, and be patient. It can take anywhere from three weeks to three months for your bulb to bloom.

At first, you should be very careful about watering. The bulb will not be able to take up much water, and with no leaves or flowers, it cannot transpire. Let the soil dry completely between watering, until you see flower buds forming; then you can water more often, but still allow the soil to dry a bit in between. Do not fertilize while your Hippeastrum is in flower.
