“Strawberry jars” refer to those clay containers which have two or more layers of pockets protruding out of their sides.

Though not exactly “jars,” containers with a similar design are also available in wood or plastic.

These containers provide perfect places to tuck, not just strawberry plants, but other small plants that need good drainage and produce daughter plants or tend to weep.

In addition to strawberries, you can choose herbs such as thyme, oregano and savory or a colorful mixture of sedum, dwarf marigold, ivy, petunia, hanging geranium and alyssum.

Choose drought-resistant plants if your chosen location is sunny, hot, exposed to drying winds or if you are not likely to water them faithfully.

For the best effect, choose at least some trailing plants for the side pockets and something with a more upright habit for the top. Just make sure the plants will adapt to the container and enjoy the same amount of water and sun as their companions.

Choose plants with similar growth rates that will complement each other in the container.

The strawberry jar represents vertical planting at its best.

You can get an impressive yield of strawberries or herbs or a variety of color and texture in very little space.

The first requirement for a successful jar is good light. If you can, turn the jar regularly so all sides get the same amount of light.

The second requirement for success is providing adequate moisture.

When choosing a container, make sure there are drainage holes in the bottom.

When planting a clay jar, first soak it for several hours to saturate the clay. This will prevent the pot from drawing moisture away from the young plants.

Water anytime the top of the soil feels dry to the touch.

Plant early in the season or shade the pot a bit until the plants adjust.

To plant, fill the pot to the rim of the lowest layer of pockets with moist, well-draining potting mixture. Push the roots of the plants through from the outside of the pockets, pulling gently from the inside.

Make sure all roots are securely embedded in the soil. Then add additional potting soil up to the next story and repeat to the top.

Position your “crowning” plant in the top and fill in any crevices with soil.

Starting from the top, give the plants a generous, gentle watering.

As the plants take hold, you may wish to apply a balanced fertilizer every two to three weeks.

Watch for wiling plants that need water, and trim enthusiastic plants before they become too tangled.

Since most plants in strawberry jars will not survive well in winter, empty and clean the pot at the end of the season.

Anyone can create an ideal garden, even in a “jar.”
