Frequently Asked Questions
How is a potting mix different from potting soil?
The ideal choice for tomatoes in containers is a potting mix rather than pure soil. Unlike potting soil, which is just soil without added nutrients, potting mix combines potting soil with organic materials like compost and moss, ensuring the presence of essential nutrients. This distinction makes potting mix more suitable for container gardening.
Why do tomatoes grown in containers often need potting mix rather than potting soil?
Potting mix is generally favored for container gardening over potting soil for several reasons. It excels in retaining moisture and draining excess water, which is crucial in the confined space of a container to prevent root rot or other diseases. Unlike potting soil that tends to compact and restrict growth, potting mix remains looser, providing more room for tomato plants to grow.
Additionally, the varied organic materials in potting mix ensure better aeration compared to the more uniform composition of potting soil. However, high-quality potting soils like Fox Farm Happy Frog can also be effective for container tomatoes due to their similar characteristics to potting mix.
Can I make my own potting mix?
You can create your own potting mix for tomatoes in containers instead of buying one. Various recipes use organic ingredients, with a common one combining equal parts garden soil, sphagnum peat moss, perlite, and compost materials like leaves or crushed eggshells. If you’re new to container planting, starting with a pre-made mix might be easier.
Alternatively, you could experiment by growing tomatoes in both a commercial potting mix and your homemade mix to compare results and determine the best option for your container gardening.
