I bought a blooming orchid for $10 at Home Depot, of all places, a couple of months ago. It has one flower left; the others have dropped off. I assume the last one will fall off pretty soon. Is the plant spent after it blooms, or can I keep it going and expect it to bloom again in my lifetime? I don't know what kind of orchid it is, but I'd call it a moth orchid rather than a slipper orchid. It has 5 or 6 strap-like leaves.
It is planted in what looks like a roll of half-rotten tree bark instead of chopped bark and/or orchid mix, so I'm not sure how I'd replant it other than set it a little deeper in a bigger pot. If I try to remove the old "soil" I'll destroy most the the roots.
I've been watering it by soaking the root ball for about 5 minutes and then draining it, and letting it dry out completely before watering again. (I think it lost a few blooms when I let it dry out too much.) I haven't given it any food yet. Should I be using distilled water (or deionized, or rain water) so salts don't build up?
Thanks, Bob
