How to Add Food Coloring to Plant Soil

You can add food coloring to plant soil for a more colorful garden. Moisture is pulled in from the soil through the roots of living plants. Evaporation from leaves and flower petals creates suction that draws the water up the plant through the interior vascular. Liquid color added to the soil is partially filtered on its way to the roots. Deliver a highly concentrated dose of color to plants in the soil for vibrant growth varieties.
