There’s an important status being reached in our gardens for seeds to germinate properly. It revolves around a word you’ve probably never heard used in a gardening discussion.

Agronomist Christie Apple says seeds need an optimum soil temperature to germinate correctly.

Firstly, we need to choose tomato varieties that ripen in a shorter amount of time. This usually means it’s a smaller tomato. Early Girl is the most commonly found earlier ripening tomato. They get about as big as a tennis ball. Most of the seed packets list the ripening time at around 60 days.
