The first thing to remember is that you won't want to plant your tree directly in the ground outside. This is one of the biggest mistakes when planting new plants. By planting directly outside the seed would be subject to the weather, predators (such as birds and squirrels), and bad soil. The best thing to do is to plant your seed in a small pot and repot it as the plant gets bigger. Some of the supplies you will need for planting are:

Seed. You will of course need the seed to plant. Make sure you find a tree that will thrive in your area.

Pots. As the seed grows you will need bigger and bigger pots to transplant it in. If your pot doesn't have any holes on the bottom it's a good idea to drill some so water will be able to drain out of the pot.

Water. You will need to remember to water your tree as it grows and matures.

Sunlight. Find a spot where you can give your tree some daily sunlight without putting it in any harm.

When watering your seed remember to keep it moist but not overly wet. If you keep too much water in the pot you have a chance of “drowning” your seed. Good ways to keep the container moist include a mister system or for a cheaper alternative you can put a piece of plastic over the pot. Remember, if you use plastic you need to put some holes in it for air to get through to the seed.
