Smart Tips for Growing Mint

Learn effective techniques to grow mint easily and manage its spread for a bountiful, healthy plant.

Prepare the Pot and Plastic Cup

Begin with selecting a pot or container that offers excellent drainage to prevent waterlogging. Mint appreciates a roomy setup, so look for a pot at least 12 inches deep and 12 inches wide. Fill it with potting soil, keeping about an inch or two of space from the top rim for easy watering.

Next, take a plastic cup and punch holes around its sides and bottom. These holes ensure that water and nutrients are gradually released into the soil, providing even moisture and essential nutrients for optimal plant growth.

Position the Cup in the Pot

Place the cup right in the center of your pot, positioning it so that the rim sits level with the soil surface. This creates an "o" within an "O" shape when viewed from above, allowing you to conveniently add water and nutrients directly.

Add Fertilizer

For a powerhouse natural fertilizer, grab some crushed garlic and dried banana peels. This unique mix is packed with nutrients that are great for your mint’s growth. Fill the cup with this mixture to ensure your mint plant receives a steady nutrient supply.

Plant the Mint

If you have mint seedlings or cuttings, start by making a small hole in the soil next to the plastic cup. Place your mint in the hole and gently pat the soil around it. Mint grows well with companions, so consider planting a few more seedlings or cuttings, keeping them a few inches apart.

Care for Your Mint Plant

To water your mint, pour water directly into the plastic cup. As the water seeps through the cup’s holes, it carries nutrients from the garlic and banana peels, delivering them directly to the mint’s roots for sustained nourishment.

Harvest the Mint Leaves

Your mint should be ready for a trim after about 8-10 weeks. When harvesting, snip just above a set of healthy leaves to encourage bushier growth, helping you enjoy a fuller, more lush plant.
