Advanced Soil Drainage Kit for Clay/Rock Gardens to Prevent Root Rot

Many gardeners, especially in areas with challenging soil like heavy clay or rock, struggle with poor drainage leading to root rot for sensitive plants. A specialized product combining soil amendments (e.g., perlite, grit, compost tailored for drainage, gypsum to break up clay) with a simple, robust planting guide could help prevent this common issue. The user's specific problem with Arbutus Marina and lavender in a consistently soggy spot highlights a clear unmet need for effective, DIY-friendly drainage solutions beyond just 'digging a bigger hole.' The product could also include instructions for creating a raised bed effect or a specific layering technique for difficult soils.
