A bucket, some leaves, and a few weeks of patience can turn a backyard plant into free fertilizer for heavy-feeding crops. A TikTok gardening tip is showing home growers how to make nutritious compost for fruiting plants.

Here's what to know

In a TikTok, content creator Planted in the Garden (@PlantedInTheGarden) explained how to make comfrey compost tea, a kind of liquid fertilizer, at home.

@plantedinthegarden You don't want to learn, but I'm gonna teach it anyways😅 Comfrey compost tea. One of the best natural fertilizers you can make at home. Here's how: → Harvest comfrey leaves. Cut them at the base. → Fill a bucket about 1/3 full with leaves. → Weigh them down with a brick or rock. → Fill the bucket with water. Cover loosely. → Let it steep for 2-4 weeks. It will smell. That's normal. → Strain out the leaves. Add them to your compost. → Dilute the tea 10:1 (10 parts water to 1 part tea). → Water your plants at the base. Comfrey is high in potassium, nitrogen, and phosphorus. Great for tomatoes, peppers, squash, and fruiting plants. Free fertilizer from the garden. Nature doing the work. #organicgardening #diy #learning #fypシ ♬ original sound - Planted in the Garden

To make it, gardeners harvest comfrey leaves, fill a bucket to roughly one-third full, hold the leaves down with a brick or stone, and pour in water. The creator suggested using rainwater. After sitting for two to four weeks, the liquid is strained and then mixed at about 10 parts water to one part tea. 

In the caption, the creator said comfrey contains potassium, nitrogen, and phosphorus and can be especially helpful for fruiting crops such as tomatoes, peppers, and squash. They described it as "one of the best natural fertilizers you can make at home."

The caption also warned, "It will smell. That's normal."

"Be warned…it stinks," one TikTok user confirmed.

People also asked whether the brew is a complete fertilizer, whether a specific type of comfrey works best, and how to keep the plant from spreading.

How does this help?

If comfrey is already growing in the yard, this method turns garden trimmings into no-cost plant food instead of letting those nutrients go elsewhere.

That can help cut spending on store-bought fertilizers, especially during peak growing season.

Gardening can save money on produce, and many gardeners say homegrown fruits and vegetables taste better because they are picked fresh instead of traveling long distances before reaching a plate.

Planting, watering, weeding, and harvesting also add light physical activity to a routine, and time outdoors can reduce stress for many people.

Homemade fertilizer is one more way to keep a food garden productive while reusing what is already on hand.

What can be done?

Simple projects like comfrey tea can make growing your own food cheaper to maintain.

No specialized equipment is required, and once the mixture is strained, the leftover leaves can still be added to the compost pile.

Since the brew gets pungent, it makes sense to let it steep outdoors with the bucket loosely covered. When it is ready, diluting it before use is important so the concentrate is not too strong for plants.

Gardeners can also use tips like this while composting kitchen scraps, watering plants at the base, and choosing crops that produce steadily like herbs.
