Select the largest pocket pot that you can find or afford. Obviously, the more pockets you have the more plants you can plant and the more berries the plants will produce. Cover the drain hole in the bottom with rocks so that the soil doesn't sift out. Combine the soil mix with a perlite by scooping it into the planter until it is even with the bottom of the lowest row of holes.
Wrap the strawberry plants roots in newspaper and insert one into each hole in the bottom row, laying the root bundle flat on the soil.
Scoop more soil around the bundles, scatter a handful of fertilizer pellets over the soil. Add enough soil to reach the next row of holes and repeat by adding soil and fertilizer. Top the soil to approximately 1" below the jars rim. The neck of the pot should be visible for easy watering.
Add enough plants to fill the top of the strawberry jar, fill gaps between them with soil, and firm the soil with your fingers. Next tuck some moss between the plants in the pockets and between the plants in the top of the jar. Pour water gently into the pot to moisten. Trim off any damaged strawberries and your planter is done!

Added Tip: You can use the same pot to plant a herb jar!

Assemble the same materials used to plant strawberries and follow those instruction to plant an herb garden. Purchase starter herbs at your garden center that are about 2 1/2" to 4" pots. Pick ones that you normally cook with or those you want to try. The best herbs for containers have the words "bush" "nana" or "compact" in their name. Parsley, cilantro, thyme and oregano are small in stature and also do well in strawberry jars. Try some of these herb garden combinations.....
