Learn Turkish: Kabak bahçede çabuk büyür. - Zucchini grows quickly in the garden.

Büyüyor is the present continuous tense ('is growing' right now), while büyür uses the simple present or aorist tense. We use this tense to state general facts, habits, or universal truths. Since 'zucchini grows quickly' is a general fact about the plant, büyür is the natural choice.

The sentence refers to zucchini in general. Why isn't it plural (kabaklar)?

In Turkish, when you are talking about a whole category, species, or a general concept, you usually leave the noun in its singular form. So, kabak here represents 'zucchinis in general' or 'the zucchini plant'.

Could I use hızlı instead of çabuk to mean 'quickly'?

Yes, you could say hızlı büyür, but çabuk is very natural here. Çabuk usually describes an action taking a short amount of time to happen (soon or in a short timeframe), whereas hızlı often focuses on physical speed (fast). Since growing is a process over time, çabuk fits perfectly.

Why is çabuk placed right before the verb?
