I've had a houseplant (not sure of the species, unfortunately) for a few (~6) months now. Until recently, the plant has been healthy.
Now, there are a few things going on with the plant that are concerning to me. I'm rather new to gardening, so I'm not sure what the problem is (I'm familiar with some deficiencies, but nothing more), and I don't really have anyone to ask. I was wondering if anyone could possibly help me determine the diagnosis and and treatment to my plant's ailment.
- Browning and yellowing of leaves at the base (phosphorous/iron deficiency?)
- Small white circles on the undersides of leaves. Upon closer inspection they don't look like aphids, perhaps aphid eggs? (See topmost leaf)
- Weird structures on the stem. Are these part of the plant? Am I just that dull?
- Very small, almost invisible black dots on underside of leaf
- Aphids, I think.
Is this just a simple aphid infestation rearing its ugly head? If so, is it even possible to have plants without aphid infestations (I've had aphid problems many times before)? Or is this multiple problems including an aphid infestation? Thank you for your help.
