How to get dirt on skyblock?

I am playing skyblock and need more dirt. I know I can make coarse dirt and till it to dirt but I need gravel for that. How can I get gravel on a skyblock if I only have a tree, an infinite water source, a cobblestone generator and some dirt? I am playing on Minecraft Pocket Edition.

Solution 1:

Now that the 1.16 update is out you can give a Piglin gold ingots and there's a 9% chance to receive gravel blocks, from which you can get dirt.

Solution 2:

Unfortunately there is no more dirt for you.

The normal Skyblock does not give you any extra dirt other than what's already available on your island.

Solution 3:

In some skyblock games you can go to a shop and Buy dirt from the shop. Sometimes chests spawn next to you too which can contain dirt. Such as Cubecraft, Lifeboat etc...
