Plant Care Indoors Surrounding Pond

Question

I maintain a large pond inside a bank with plants growing around the pond as well as several areas in the bank. I have recently planted hibiscus in pots around the circumference of the bank and hydrangeas around the pond. The hydrangeas are in full bloom at this time. I also planted 2 ice orchids near the water fall. With the additional humidity of the pond, I am unsure of the watering requirements. Can you advise me – both on watering and required care of plants surrounding pond? All plants receive indirect sunlight through skylights most of the day.

Answer 1

Before watering, you should always determine the level of moisture in the soil by testing it, either with a simple electronic moisture meter, or by inserting a pencil or wooden skewer into the soil. The soil for hibiscus and hydrangeas should be slightly damp before watering again.
“ice orchids” are not a type of orchid, but rather a commercial marketing label. Chances are you have a phaleonopsis or dendrobium orchid. They need to be repotted into correct orchid mix, allowing for good drainage, and they then can be watered when you water the other plants.
