Fern Propogation Questions
My 10 year old son has a large fern that he bought at Wal-mart on clearance. It was badly in need of repotting and when I did so I noticed little ball like "things" in the roots. Figuring they might be some kind of baby plant (I'm not a fern person, obviously), I pulled two out and planted them in moist potting soil.
The last time I checked them, they had both started to grow a little sprout (under the soil). Yesterday, one had popped out of the soil a good half inch or more. The little ball like things have pushed themselves up almost even with the soil surface, too, which is kind of odd.
Now, while I've grown plenty of plants, this is our first experience with ferns! What are these little round ball thingies called (I'm afraid I don't know the type of fern -- they are the huge ones walmart always has for $5-10 that you see everywhere). Is there any other special care I need to give this baby fern? I made a mini greenhouse for the pot today out of a plastic bottle. I'll watch for condensation and adjust moisture if it gets too wet in there -- I know it's hard to keep enough humidity for ferns and it's been rather dry here of late. It's sitting on my desk so that I will notice if it starts dripping too much in there.
Any ideas / information on this would be welcomed...My son likes his fern so much and would love for its "baby" to survive.
