Easy to Grow
Calla lilies are one of the easiest plants to grow in containers. And, this is how you should grow them living in a cold or wet climate region. Seeing calla lilies year after year in cold climates, means taking a few extra steps. And caring for them through the winter months. Growing Calla Lily plants in cold climates is not difficult.
What is a “Cold Climate”?
Cold climates are those that have sustained temperatures at or below freezing.
There is some success growing Calla lilies in colder climates outdoors. However, they will not survive once the tuber temperature reaches at or below freezing. In addition, Calla lilies bulbs should be planted no more than two inches deep. In any climate as well as outdoor gardens, landscape. They freeze or get too wet.
Callas are perennial plants, lasting for years. Growing calla lilies need to be in containers or pots. As a matter of fact, they grow best this way.
Here’s What To Do
Tubers Arriving Fall
1: Store in a paper bag with slightly damp newspaper. Also, for a minimum of 8 weeks store in a cool, dry place. Such as your garage or even your house. Growing calla lilies, need a “rest period” after blooming. In addition, they expend large amounts of energy growing. And producing blooms.
After The Rest Period
2: After storing for 6 to 8 weeks, then plant in a container (follow our planting and care instructions included with your order). Grow indoors. Alternate with direct sunlight for a couple hours per day, if possible.
After Growing Calla Lilies Indoors
After ALL possibility of outside freezing temperatures have passed. Then place your Calla Lily outdoors in the container. Do not place your growing Calla Lily in direct sunlight after growing indoors. Consequently, the leaves will burn. Place it in a cool, shady area for a few days. Then move it to a more sunny location.
3: After blooming, the leaves start to turn yellow. Then, remove your Calla tuber from it’s container. In addition, clean off the potting mix. And let the tuber, roots, stems, and leaves dry. Remove the dead or dried parts of the tuber (roots, leaves, etc.). Equally important, do not to damage the tuber.
Tubers Arriving Spring
1: We have already given your Calla tubers its’ 6 to 8 week “rest period”. Needed for them to bloom the current Spring. However, if you still are having cold or snowy weather, then follow step 1: Fall arrival (above). Otherwise, follow steps 2 and 3 of Fall arrival (above).
Calla Lilies are non fragrant, can bloom through a 6 month period, and are very easy to grow!
Callas grow best in containers large enough to support root and tuber growth.
Calla Lilies can be grown in partial shade or full sun but do best in morning sun and afternoon shade.
Callas are usually pest free.
Callas need a minimum of an 8 week “rest period” in order to bloom the next year. DO NOT ALLOW THE TUBER TO FREEZE DURING IT’S REST PERIOD!
You can “jump start” your Calla Lilies by growing them in your house for awhile or as a permanent house plant. Just remember to remove the tuber in the Fall and give it a rest.
Callas grown in containers need plenty of room for root and tuber growth. Use a large enough pot or container to give your Calla tuber and roots plenty of room to grow.
When placing your Calla plant grown indoors to an outside location, remember to place it in a cool, shady location for a few days. Otherwise the leaves may burn.
Calla Lilies are heavy feeders. Remember to add a fertilizer to your potting mix low in nitrogen (no more than 10%) and high in mineral content.
I recommend not using a fertilizer mixed with water then applying it to the leaves. Instead, use a small amount of slow release granular fertilizer applied directly to the planted Calla Lily pot or container every 3 to 4 weeks.
Calla Lilies do not require or need a lot of water. Keep the potting mix moist to dry…NOT WET. If the potting mix is too wet, the tuber rots! I very seldom water my potted Callas more than once a week, whether grown indoors or outdoors.
Always keep your soil or potting mix at 6.0 to 6.5. Calla lilies prefer an acidic soil or potting mix. Use our soil pH tester meter. Then adjust accordingly.
