How to Reuse Margarine Tubs for Home Gardening

Once empty, margarine tubs can take on a useful role for people growing plants at home. When properly cleaned and adapted, they can be used temporarily to sort seeds, store small items or hold seedlings.

How can a margarine tub support plant growing?

The shape of the container makes it easy to reuse for minor gardening jobs. It can help divide up seeds, keep labels together or collect items such as clips, string and small tools.

It can also work as a temporary container for seedlings. In this case, the base must be altered so water can drain away, as too much moisture may damage the roots.

How to turn a margarine tub into a seedling container

Wash the tub thoroughly to remove every trace of food, then allow it to dry. Next, make small drainage holes in the bottom using a suitable tool, taking care not to cut yourself.

Add a growing medium suited to the species, then plant the seedling or seed at the recommended depth. Place the container where it meets the plant's light requirements, and manage watering carefully to prevent waterlogging.

What can be stored inside the tub?

A lidded container can serve as a small box for seeds and gardening accessories. Labels, wire, string, clips and other small objects that often get lost among larger tools can be kept separately inside.

When storing seeds, only keep material that is completely dry. Labelling each container with the species name and, where needed, the storage date will also make organisation easier.

What precautions matter when reusing it?

The tub should be undamaged, with no cracks or sharp edges. If it is used for seedlings, it must be cleaned and have suitable drainage. Very small containers can also restrict root growth, so they should only be treated as a temporary option when a plant needs more room.

It is also unwise to leave improvised plastic containers outdoors for extended periods without checking how well they withstand sunlight and weather. Therefore, reusing a margarine tub can be a straightforward way to reduce waste and create useful resources for home gardening.
