Hi buddy, mum tells me you’d like to make some seeds grow into a plant that will end up giving you more fruit? Well I think that these would be the best where you live which is all covered in snow at the moment.
These all can get to be big trees but if you put them in a pot on your balcony they will probably stay small enough. But the best thing for you to plant if you like them I think is blueberries.
Tell mum they like acid soil so she should tip her tea leaves and coffee grounds on them. Tell her to buy you some punnets of blueberries, eat them but keep the seeds ( they’re quite small so be careful) put them in a pot filled with potting mix and keep them moist -not wet, not dry until you see leaves growing. This might take a long time so be patient because it will be worth it. When you grow your own blueberries mum can make you blueberry muffins and stuff.
Let me know what you decide on and how it all goes buddy, we can do this together.
