Using a Bamboo Stake to Measure Soil Moisture

A smeared, muddy stake would indicate the plant is over-watered. But, evenly distributed soil flecks (crumbs), as shown in this image, indicate ideal soil moisture across all root-zone levels, and the plant needs no water.

An old tomato stake can be used to measure soil moisture and prevent waterlogging.  Use the simple “sight and touch” with the stake before you decide to water your vine.

You thrust the stake into the soil about 8″ and quickly pull it up and examine it. If it’s smeared and muddy, the soil is saturated and needs no water. If it’s relatively dry and flaked with soil, the soil moisture is ideal. If it comes out clean, run it through your fingers and see if you can feel any moisture—if not, then definitely water the plant.   Although the appearance of the soil on the stake is important, running it through your fingers to sense the soil moisture can be more useful.

We generally recommend using a metal soil sampler, but the bamboo stake will work in a pinch.   Click here how to use a metal soil sampler.
