Although most soil garden issues can be solved with compost and sweat equity, a few require the services of professionals. Learning when to tap-out and bring in the pros will save you time, money, and maybe even your health.
Contamination Concerns
If your property has an industrial past, near petrol stations or had old paint disposal then soil contamination may be high. Composting won’t make lead, petroleum by-products or heavy metals go away so soil testing should be done professionally to ensure a safe living environment.

Severe Drainage Issues
Ponding that lasts more than a few hours after rain (and for days in some cases) is always a very serious sign of sustained poor soil drainage conditions. Organic matter works on minor issues, but if your yard is waterlogged all the time and sloped so that paving over may cause drainage problems elsewhere or lead to erosion you aren’t likely to cure it without professional grade drains or soil rebuilding beyond most home owners expertise.
Extreme pH Levels
Home remedies are fine when garden soil is slightly acidic or alkaline. The use of lime, sulfur or buffering agents in professional soil amendment must be based on knowledge so that things don’t get worse.
Structural Problems
If your soil is so dense and hard that you cannot even break it up with repeated tries, or sandy enough to drain all the water and nutrients right through it time after time, then maybe it wandered beyond the range of a shovel and instead needs heavy machinery from professionals.
Persistent Plant Failure
If several different plant varieties fail to grow, despite appropriate care and minimum soil amendments—compaction could signify underlying issues such as nematodes or the presence of soil-borne disease or chemical imbalances that necessitate expert diagnosis.
