I have a garden area measuring 3 meters by 4 meters with red clay soil that has good drainage and some worms. However, it's still quite clay-heavy and not very fertile. I've heard some suggestions about adding sand for improvement, but the only type of sand I can find is construction sand. I've also been told that adding compost could help, but I'm not sure how much I should use. Can anyone provide me with effective strategies to convert this clay soil into more fertile, black soil, or at least enhance its quality?

You might also consider using gypsum—it helps to break up dense clay soils effectively. Just keep in mind that it takes some time to see the benefits. It can really improve the soil structure over time!
Definitely avoid adding construction sand; it can actually make things worse. Instead, focus on incorporating compost or well-rotted manure into your soil. It's the best way to improve texture and fertility!
Yeah, and don't hold back on the compost—mix in as much as you can! Your plants will thank you later.

Sounds good! I'm just wondering if gypsum really makes a noticeable difference in the long run?
