How do i look after indoor orchids.?

Make sure they have plenty of sunlight and try to keep them our of the direct path of the air conditioner. On a windowsill is an ideal spot. Give them about a cup of water every few days, with plenty of drainage and mist them with a very clean spray bottle that has never had cleaning chemicals in it, only water. A lot of water usually drains out of mine, so I will leave my wide mouth watering can under the pot to collect the water and allow the orchid to absorb additional moisture through the air. In the wild, they are air plants and will absorb all their water and nutrients through the air. Once it is done blooming, don't stop watering, although once a week is fine then. It will send up new spikes and flower again in about 3-9 months. Good luck and Happy New Year!
