We’ve received a terrific selection of small conifers this week that are perfect for bonsai or growing in containers. They can be grown individually or used in mixed containers. These selections are priced at 14.99. Look for the display near the information desk in the greenhouse.

Tips For Growing Conifers in Pots

Any type of container is fine for conifers as long as it has a drainage hole. Choose one that is at least 3-5 inches wider than their original pot. One point to consider is that lighter materials like terra-cotta will dry out faster and require more frequent watering. Heavier pots like concrete or ceramic are good choices for larger conifers and will not tip over as easily.
Use a high-quality potting mix like Edna’s Best.
Before planting, submerge the plant in a bucket of water until all air bubbles have stopped.
After planting, apply a layer of mulch (bark chips, gravel, etc.) but keep the area around the trunk clear.
A slow-release granular fertilizer applied once per year (preferably in the spring or early summer) is all that is needed.
Position the plant in a sunny or bright location and preferably not in a windy spot. Conifers are versatile and can cope with various light conditions but try to provide at least 4-5 hours of sun if possible.
Water a few times per week or daily if temperatures are above 85. Water thoroughly until you see water running out of the bottom of the pot. Do not over-water. It is usually fine to wait a few days between watering if temperatures are not high. If in doubt, check the soil with your finger. If it feels moist, it is okay.
During the winter months, containers can be left outdoors but preferably put in a protected spot away from harsh winds. Regular rainwater should be all that they need.
Conifers are slow-growing and can remain in the same pots for many years before having to be re-potted.
