Planting Silver Posie Thyme in a Container
Scoop potting soil into a 6-inch wide (or larger) planting container until it's about 1/2 full. Make sure you choose a planting container that has at least three drain holes. You can make your own potting soil by mixing together equal parts sand, compost, sphagnum moss and vermiculite. According to Floridata.com, silver posie thyme likes being grown in neutral to alkaline soil, so add 1 tbsp. of garden lime for every cubic foot of planting soil you create.
Pour enough water into the container to saturate the potting mix.
Remove the silver posie thyme from its current growing container. If it's growing in a planting pack, force it up from underneath the cell using your thumb or index finger. If the silver posie thyme is growing in a 4-inch pot, turn the container upside down with one hand on top of the root ball while you tap along the pot near the drain holes to loosen the pot from the root system. Then slide the container off the root system.
Loosen any compacted, entwined or matted roots from the root ball of the silver posie thyme.
