First timer looking for tips and advice

[Greenthum]

Hey guys I just moved to brisbane a few weeks back, on our house warming the chop got spilt off the table and went everywhere yesterday I found two seedlings growing in the cracks of the pavers I managed to save one but lost the other, I planted it straight into a decent sized plastic cup, with drainage holes, with soil out of the garden and glad wrap over the top, iv had it in the sun all morning and put it in the shade around 1pm everything seems to be going fine just wondering the steps from here, would like to keep it outside preferably but still want decent fruit from her.

Any advice would be appreciated cheers
