Step one find the shop that sells gardening supplies and make sure to buy everything you need including plant food/water and obviously tools to plant/harvest your plants when you are done.

Step two head to a green surface or a surface with soil/dirt. (You are only able to plant on green surfaces or on dirt. You can also plant inside of houses (if you purchase a house with see-through windows open a ticket if you are unable to plant inside of the house as admins need to approve your house for planting first) Houses with no windows are strictly prohibited from growing any plants inside as this would stop pd from doing their RP.

Step three use the seed to plant your tree. Make sure you have a plant pot and a shovel to plant your seed in and keep your plants fed and hydrated otherwise they will die.

If you are in the middle of a grow and there is a restart about to happen all trees are saved before and after restart. Do not worry about your plants, they will still be in the same place where you left them after restart.
