Here’s where it gets fun. You have options, and your choice says something about your gardening personality. Straw (not hay, which has seeds) is the zen minimalist’s pick—it’s clean, light, and breaks down nicely.
For the maximalist, compost or shredded leaves are a two-for-one deal: they mulch and feed your soil like a slow-release nutrient IV drip. Just avoid fresh wood chips, which can steal nitrogen as they decompose.
Want a modern, almost architectural vibe? Try red plastic mulch. It reflects light back up to the fruit, supposedly boosting sugar and ripening speed. You’ll feel like a tech-startup founder optimizing your crop’s output.
