Self-sowed Melon

I do gardening with home-made compost.

Compost is composed of decomposed organic materials.
As the materials decompose, heat is generated. Unwanted weed seeds and bacteria are killed with this heat. Theoretically.

Somehow my compost doesn't become hot enough to kill seeds.
Past years, I witnessed plants like potatoes, tomatoes, and even chili pepper emerged from compost which was scattered on the garden.

This year, I found yellow squash look-like plant was growing in my vegetable garden.
I don't have any recollection of throwing yellow squash seed since I eat them all, but I have no objection growing it in my garden, so let it grow.

After a while, it didn't look like yellow squash.

Watermelon...?
I waited more and found out...

It happened to be cantaloupe melon!
I grew melon from a seedling some years ago but never saw it self-sow.

I cut it into half and tried.

Not much meat...and a little sour... but it definitely tasted like melon!
