I'm really in need of some help/advise regarding my Lemon Plant.
A mate gave it to me 25 years grown from just a lemon pip .
The thing is I keep getting these brown aphid like pests that make the leaves sticky and despite cleaning them along with the stems, they keep reappearing and now the leaves are looking a bit sorry. Curling and dry on the edges.
Ive read soapy water, rubbing alcohol (really?) gets them off but I really could do with some advise on improving the health of the only plant I own and treasure.
Thanks in advance and Merry Christmas
