Care of Lemon and Lime Tree
First time posting and really just looking for some advice. My sister has a small Lemon and Lime tree in large terracotta pots which she was just given and has asked that I look after them for the next couple of weeks.
I noticed the lemon is currently covered in aphids and have seen some helpful sprays on the forum which I will try. It also has leaf curl and yellowing of the leaves at the top.
I am wondering if someone can give me some advice as to whether I should prune now in Autumn and when/whether I should fertilise them now or at another time in the year? Any other care tips needed for this time of year?
Also, the trunk below the graft is shooting off a very spiny, small leafed branch on the lemon tree. Should I cut this off and what probably is it?
Aside from the aphids, the trees look very healthy and the lime has fruit on it at the moment with more coming through.
Thanks for any help!!!!
