15 Kitchen Herbs & Vegetables You Can Regrow in a Mason Jar of Water

Imagine turning kitchen scraps into a mini indoor garden.

No backyard. No raised beds. No expensive equipment.

Just a mason jar, fresh water, and a sunny windowsill. 🌿

Many common herbs and vegetables can regrow from cuttings or leftover bases you’d normally toss away. While some thrive long-term in water, others eventually need soil for stronger growth.

Let’s break them down clearly — so you know what to expect.

🌿 Herbs That Root & Grow Long-Term in Water
