Caladiums are a popular choice for adding vibrant color and lush foliage to shady gardens. Their striking leaves come in various shades of red, pink, white, and green, making them a favorite among gardeners in Zone 7. With proper planting and care, caladiums can thrive and brighten up your landscape during the warm months.
Understanding Zone 7 and Caladiums
Zone 7, which includes parts of the southeastern United States, has a moderate climate with mild winters and hot summers. Caladiums are native to tropical regions and thrive in warm, humid conditions. They are sensitive to frost, so planting them at the right time and providing proper protection is essential for success in Zone 7.
Choosing the Right Caladium Varieties
There are many caladium varieties suited for shady spots in Zone 7. Some popular choices include:
- ‘Miss Muffet’ – known for its white and pink leaves
- ‘Red Flash’ – with vibrant red and green foliage
- ‘Pink Symphony’ – featuring soft pink and white leaves
- ‘Florida Sweetheart’ – with bright pink and green colors
Planting Caladiums in Shady Areas
Timing is crucial when planting caladiums in Zone 7. The best time is after the last frost date in spring, typically between late April and early May. Choose a location that receives filtered or dappled shade for optimal growth. Caladiums prefer well-draining, rich soil with plenty of organic matter.
Follow these steps for planting:
- Dig holes about 2 to 3 inches deep.
- Place the tubers with the pointed end facing up.
- Space tubers 12 to 18 inches apart.
- Cover with soil and water thoroughly.
Caring for Caladiums in Zone 7
Proper care ensures that your caladiums flourish throughout the growing season. Keep the soil consistently moist but not waterlogged. Mulching around the plants helps retain moisture and suppress weeds. Fertilize every 4 to 6 weeks with a balanced liquid fertilizer to promote healthy foliage.
During the summer, caladiums thrive in warm temperatures. However, as fall approaches and temperatures drop below 60°F at night, it’s time to prepare for dormancy. In Zone 7, you can either:
- Dig up the tubers and store them in a cool, dry place indoors for winter.
- Or leave them in the ground if you provide winter protection such as mulch or a frost cloth.
Overwintering Tips for Zone 7
If you choose to store tubers indoors, carefully dig them up after the foliage has died back. Clean off excess soil, let them dry for a few days, then store in a paper bag or box in a cool, dark area. Replant in spring once the danger of frost has passed.
With proper planning and care, caladiums can be a stunning addition to your shady garden in Zone 7. Their vibrant leaves bring color and life to areas that might otherwise be dull during the growing season.
