Caladium plants should be started indoors four to six weeks before the last spring frost, according to Iowa State University Extension and Outreach. This will give the tubers enough time to put down some roots and for shoots to emerge from the growth “eyes” along the top of the tuber.
How long does it take for caladium bulbs to sprout indoors?
They do equally well outside or inside as houseplants. Regardless of which you choose, caladium bulbs can take between two and 12 weeks to germinate. Because they love hot weather, the warmer the ground and air temperature when you plant, the faster they will grow.
Should you soak caladium bulbs before planting?
If you are living in a colder environment, a good practice is to soak the bulb in lukewarm water for about an hour before planting them. In our tropical climate, this step can be skipped as our weather is warm enough to trigger the bulbs to sprout.
What month do you plant caladium bulbs?
They can be planted directly in the garden during spring or started indoors four to six weeks before the average frost date. Soil temperature is an important consideration, as planting too early outdoors can cause tubers to rot. These plants thrive in moist, well-drained soil and are generally happier in partial shade.
Can caladiums grow indoors year round?
Caladium thrives indoors in indirect light, making this South American native a spectacular tropical accent for your home. You can expect the showy season to last for 6 months or longer. Caladiums thrive in warm, moist conditions. Give them bright, indirect light and humidity.
Is it too late to plant caladium bulbs?
Caladium bulbs are safely planted outdoors when night time temperature are staying consistently above 65 degrees. It is never too hot or too late to plant caladiums. Planting caladium bulbs is super easy.
What month do caladiums bloom?
Caladium plants bloom anytime from spring into autumn when the plant is in its active growth cycle. The North Carolina Cooperative Extension Service describes a caladium flower as being an inconspicuous spadix that is less than 1-inch in length, emerging from a trumpet-shaped spathe that is yellowish-green in color.
What time of year do caladiums come back?
Just as potato tubers provide us energy when we eat them, caladium tubers provide energy stores for tubers to go into winter dormancy and grow again in spring as the days lengthen and the soil temperatures rise in the right hardiness zones.
Which way do you plant caladium bulbs?
Caladium bulbs have a rather smooth bottom side and a knobby (these are actually the eyes or growing points) top side. Gently put the Caladium bulb in the ground, with the eyes (knobby side) pointing up. Add a little bone meal to the soil and plant other bulbs about 4-12 inches apart depending on the size of the bulb.
Can I plant caladium bulbs in June?
Plant the tubers only after the soil temperature has warmed up to 65°F. In the central U.S. this will be sometime around Memorial Day. In northern areas you may need to wait until mid-June.
How long does it take for a bulb to grow?
In any case, the bulbs first need to grow roots and become established, and then they will send up top growth so I think you may still have a while to wait. The glads take 70 to 90 days to bloom, and are usually planted in succession over about a ten week period to assure a progression of blooms in the garden.
Where should I place my caladium indoors?
Indoor Caladium plants require a medium light area with protection from midday sun, which will scorch the leaves. A northern or eastern window is usually the best exposure.
Do caladiums go dormant indoors?
When grown indoors, they do best with lots of heat, bright but indirect light, and plenty of humidity. Even under the best conditions, caladium foliage lasts only a few months before the leaves start to die back and the plant goes dormant again, which is normal.
How do I make my caladium bushy?
Take a sharp knife and cut out the large central bud from your fancy leaf caladium bulbs before you plant them. This will encourage the growth of the secondary buds and give you a fuller but just as colorful plant. Fancy leaf caladiums require loose, slightly acidic soil for good root growth and are heavy feeders.
When should I wake up caladium bulbs?
In March and early April, it’s time to wake up most of the plants that you put into dormancy in the basement for the winter, including tender bulbs like cannas, callas, tuberous begonias, caladiums, dahlias, gladioli, and alocasias. It’s also time to start any pelargoniums (geraniums) that were likewise stored dormant.
Do caladiums need deep pots?
Start with a large planter, at least 18 inches wide and deep, with drainage holes in the bottom. Make a well a few inches deep in the center of the planter and tuck in the caladiums. Add additional flowers such as begonias and petunias. Fill in with potting mix, and water the plants in.
How deep should caladium bulbs be planted?
For outdoor landscape planting, find a spot where your Caladiums will receive filtered sunlight, bright indirect, or partial shade. Dig holes and plant the tubers about 2″ deep and 8–12″ apart with the growing points or “eyes” facing up.
