My Sister is a novice with plants and her mother in law gave her an orchid and it's not doing good, now her mother in law is upset thinking she is lazy neglecting her "gift".
I'm the plant expert in the family, but I've never owned or grown an orchid, no room in my house.
I know they like moist but not soggy substrate and humidity and require staking for the flowers, and they have thick support roots and flowering stems grow from the side, but other than that I don't know much. I've seen orchid fertilizer pellets sold.
So my sisters plant is on a windowsill and gets a good amount of light but its drafty in winter and hot in summer. It's 2 years old and hasn't bloomed and it's in the same substrate and phorid flies are infesting it.
What substrate is used for repotting, they don't water often so is plastic pot good over bottom with pebbles in water? Do roots get trimmed?
Here are photos, I have no idea what kind it is.
