I have 4 orchids, I always wanted an orchid plant but I thought that it is tricky to take care of it and that they are pricey.
When I got my first orchid (Phal ofc) I saw that it is in fact really easy to take care for it. If it is healthy, you just have to make sure to water it every 1-2 weeks ( when roots become greyish), it is better to keep it dry than over water it.
You will notice that when you water it, roots will change color from gray to dark green.
Also, it is important that it isn't placed on direct sunlight because then you could get sunburns on orchids leafs and they become yellowish. And thats it for 101 orchid care, sort of .
