Vegetable Garden Compost Features

There are a couple of things you need to consider when you purchase compost for your vegetable garden. The requirements for every vegetable aren’t necessarily the same so you need to find a compost that offers the right mix of nutrients and minerals.

Organic Ingredients

Since you will be growing vegetables that will most likely end up in your kitchen, it’s important to only use compost made with organic ingredients. Some compost products may come with labels stating the compost is not suitable for vegetable gardening so watch out for them.


Some compost will come with a funky smell due to the ingredients they are made of. If you don’t want your vegetable garden to be smelly then consider getting compost made of materials like earthworm castings. Odor-free gardens are also less likely to attract rodents and pests to the backyard.

Pest and Weed-Free

Poor-quality compost may come with unwanted pests and weed. They may not be visible at first but will eventually appear and cause havoc in your vegetable garden. Don’t go cheap with the materials and ingredients used to grow your food.
