What Bricks Do I Need to Make the LEGO Apple Tree?

You can create this simple LEGO apple tree using traditional LEGO bricks, and you don’t need any special pieces at all!

That makes this LEGO apple tree activity for kids one of my favorites.

You likely have enough LEGO bricks for your whole class to design their own LEGO apple tree.

If not, here are some of my favorite places to get more LEGO bricks without spending a lot!

As a STEM educator, I prefer to buy pre-owned LEGO bricks in bulk.

This method is not only more budget-friendly than buying brand-new sets, but used sets often have many more pieces that are perfect for classroom LEGO projects.

I’ve found great deals on bulk LEGO pieces on Etsy.

  • LEGO Bricks
  • LEGO Wall pieces
  • LEGO Red 1x1 bricks
  • LEGO Leaf pieces
  • LEGO brown arch pieces (2)
  • LEGO Green base plate
  • LEGO Leaf sprout
  • LEGO Black jewel


Here are the pieces used in this apple tree LEGO life cycle set. supplies to make a tree life cycle from lego

Follow the pictures below to see how we built our apple life cycle LEGO set.

First, use a small block as a seed. lego tree seed

We had a brown flower piece from some set, but a brown 1 block would also work.

For the sprout, we found a little green decorative bush from a set that we own. lego tree sproutIf you don't have something similar, you can put a leaf on top of a 2X2 brown brick.

For the young tree, we stacked three brown 2X2 bricks and put two leaves on top. lego tree sapling

For the mature tree, we used 8 brown castle tower pieces and some supporting brown pieces. how to build a lego tree

We also used 2 brown arches to make a branch. Some leaves completed the tree, then we used red 1 bricks to represent apples.

We had a lot of fun building our LEGO tree life cycle!


Don't get too caught up in replicating it exactly, the most important thing is that the kids create a model that looks like a tree's life cycle to them.

It doesn't have to look exactly like ours.
