Hi all,
I am new here and new to gardening scene but I have started with indoor and outdoor plants specially fruiting trees.
last month I bought lime plant from Aldi Grafted dwarf Tahitian Lime and at the moment I have planted the lime tree in the pot of size 46X36cm (shown in the 2nd photo) and looking for some tips from experienced people on how to care for it. As I am currently renting and I have planted the lime plant in a big pot, so please pour in your suggestions and tips. I have currently used citrus potting mix, organic compost, slow releasing fertiliser, Epsom salt and once a month seasol water.
PS- I live in Melbourne
Thanks in advance for all your guidance.
