Question
Hi, I am a beginner with orchids, but I received a phal white orchid a few months ago. The flowers wilted one by one - I found out it was because I wasn't watering them enough, so I took the garden store's advice and cut it down to the spike once the last flower fell.

I've been watering it (I believe the base is peat moss) but I just noticed today that there are 2 green spike things coming out from the moss. I'm guessing those are roots? Is that a good sign? Should I be getting a bigger pot? because they are coming out of the moss... also is the spike supposed to grow again soon? I was a little nervous about cutting it so drastically.
Thanks!

Answer
Cutting the flower spike back after it has finished flowering is OK.  Normally, Phalaenopsis flower once per year.

To have healthy roots is good.  However, growing the plant in moss can be tricky as moss tends to compact over time, reducing the air supply to the roots.  That may be why your roots are trying to get out of the moss.  I recommend that you purchase a bag of orchid potting mix and then unpot your plant (Phalaenopsis orchids benefit from an annual repotting) and wash all of the old potting mix from the roots.  This will enable you to determine the condition of your roots.  Those that are mushy should be removed as they are dead.  Healthy roots are firm and will provide the basis for future plant growth.  Then I recommend that you repot your plant in the orchid potting mix and water it thoroughly once per week.
