Caladiums can be bought as potted plants or as tubers that are dormant. Their size varies according to the variety. Each tuber, for the most part, has a huge bud that is often flanked by smaller ones. Many gardeners find it beneficial to take off the giant bud with a knife after planting caladium bulbs to make it simpler for these smaller buds to sprout. Of course, this is a personal choice that will have no effect on the general growth of your caladiums.
Caladium bulbs require little effort to plant. They can be planted immediately in the garden in the spring or seeded four to six weeks ahead of the usual frost date inside. Planting tubers too early outside will cause them to rot, so soil temperature is crucial.
These plants prefer moist, well-drained soil and prefer to be partially shaded. Caladiums should be planted 4 to 6 inches (10 to 15 cm) deep and 4 to 6 inches (10 to 15 cm) apart when planted.
If you’re growing caladiums indoors, keep them warm and bright until the weather warms up enough to move them outside. The knobs, or eye buds, of caladium tubers should face up and be planted one to two inches (2.5 to 5 cm) deep. While certain kinds may be difficult to recognize, those that are planted upside down will nonetheless develop, albeit at a slower rate.
Should I soak my caladium bulbs before planting?
Caladium tubers resemble a cross between a potato and a ginger root. They arrived on a paper roll with dry rice husk filled within. They serve as a cushion as well as a means of keeping the tuber dry during shipment. According to what we’ve read, it normally takes 13 weeks for the first leaf to appear.
A Caladium bulb has two sides: one on top and one on the bottom. Leaves sprout from what are known as eyes, which resemble potato eyes. The eyeballs, on the other hand, can only be located on one side of the bulb. The bottom side is usually smoother and free of irregularities. If you live in a colder climate, soaking the bulbs in lukewarm water for about an hour before planting them is a good idea. This stage can be bypassed in our tropical region because the temperature is warm enough to cause the bulbs to sprout.
What is the best time to plant caladium bulbs?
A: Caladium bulbs should not be planted until after May 1st. By that time, the soil temperature should have reached 70 degrees. Caladium plants can be planted if you want to get your caladiums up and running as soon as feasible. These are already a few inches tall after being raised in a nursery. Remember that caladiums cannot withstand low temperatures, so even if you use these transplants and plant them before May 1st, you risk losing them.
Which way do you plant caladium tubers?
Caladiums are tropical foliage plants that add color to flower beds in the summer. They thrive in shady spots, containers, hanging baskets, and as border plants. Caladiums are tropical plants native to Brazil that thrive in a warm, shady, humid climate. In just one season, they can reach full heights of 12″ to 30″!
Planting Caladiums in Your Garden
With the addition of caladiums, you can add drama to any landscape. Their vibrant leaves, which come in colors of red, pink, white, and green, look great in a cluster or as a contrast to other plants. Elephant Ears, which are big and spectacular, are also members of this family. We are pleased to offer Classic, Upright, and Black Magic Elephant Ears in addition to the beautifully colored caladiums.
When & How to Plant Caladium Bulbs
You can start your Caladium bulbs inside 6 weeks before the latest frost date if you want to give them a head start. If you start your Caladiums bulbs outside, make sure the soil is warm before planting them; the night temperature must consistently reach the high 60s or higher.
It’s crucial to choose the correct spot for your outdoor caladium, and well-draining soil is a necessary. The outdoor caladium thrives in partial sunlight. Whereas most plants don’t perform well in the shadow, caladiums thrive in it! White Wing, Florida Moonlight, and our White Mix have lighter colored leaves that will put on a spectacular show in shaded areas all season.
Caladiums prefer rich soil, so if yours is lacking, add plenty of compost and manure. Finally, place the caladium in an area where it will not be harmed by severe winds. The plant’s big leaves might be damaged by too much wind.
Growing Guide
Plant the caladium bulbs (or tubers) in 3-4 inch deep holes with 1 1/2 to 2 inch of dirt covering them. Caladium bulbs have a smooth bottom side and a knobby top side (which is where the eyes or growth points are). Place the Caladium bulb in the ground gently, with the knobby side of the bulb pointing up. Plant other bulbs approximately 4-12 inches apart, depending on the size of the bulb, in the soil with a little bone meal.
To encourage the caladium to take root, give them plenty of water. Caladiums need to be kept damp during germination, but not soggy. A bulb can deteriorate if it is exposed to cold nights and excessive dampness. It’s easy to detect when to water the caladiums once they’ve broken ground because they’ll droop if they’re thirsty. Your watering schedule will need to be adjusted based on your climate and the quantity of sun the plant receives.
Caladiums are easy to cultivate and require minimal maintenance. Fertilize with a general-purpose fertilizer once a month outside. Use a liquid fertilizer every two weeks inside. Remove any dead or damaged leaves during the growing season.
Enjoy!
Caladiums in the shade have larger leaves and want to be taller to catch the light, but caladiums in broad sunshine have smaller leaves and want to be shorter. Colors can also change depending on the amount of sunlight and fertilization.
Preparing for Next Season
When the growing season is through, remove the yellow growth from the foliage (temperatures remaining below 60F). Dig up the caladium bulbs before the frost arrives if you live somewhere where winter is a worry. Place the caladium bulbs in a cool, dry location and remove the dead leaves before storing them in net bags until spring. Ensure that the temperature in the storage space for the bulbs does not fall below 60 degrees.
How deep should you plant caladium bulbs?
Caladiums are tropical plants that grow quickly enough to be used as annuals in milder climes during the summer or as houseplants all year. These low-growing show-stoppers thrive in warm, damp, gloomy locations where many other plants would perish. They can survive in filtered sunshine, intense indirect light, or partial shade, but prefer full shade in hotter climates. Provide them with well-draining soil, and if water puddles appear 56 hours after a heavy rain, choose a new location or enrich the soil with organic material to promote drainage.
When to Plant
After the risk of frost has passed and daytime temperatures remain over 70 degrees, plant your Caladium tubers outside in the spring. Although these plants will only develop in warm soil, if you live in a colder region and want to get a head start, you can start them inside 46 weeks before the normal last frost date. Your Caladium tubers will sprout and root a few weeks after planting, depending on the soil quality and air temperature.
How to Plant
- Find a site where your Caladiums will receive filtered sunshine, brilliant indirect light, or moderate shade for outdoor landscaping planting. Plant the tubers about 2″ deep and 812″ apart, with the growth points or “eyes” facing up, in holes dug about 2″ deep and 812″ apart.
- Select a container with adequate drainage holes and fill it with good quality, well-drained soil for container gardening. Almost any potting medium that is commercially available will suffice. With the growth points or “eyes” facing up, plant the tubers about 2″ deep.
How to Grow
- Water your Caladiums just enough to keep the soil slightly damp, but never saturated.
- After the season is through, tidy up the garden by removing any yellow foliage.
- If you reside in a climate with cold or wet winters, dig out the tubers before the first frost in the fall. Allow them to air dry for a few days before keeping them with peat moss in a cool spot.
- Allow a few months for your Caladiums to rest before starting the next growing cycle.
Caladium Tips & Tricks
- To increase the level 23″ and enhance drainage, amend the soil with compost, finely crushed bark, or composted manure.
- Caladiums should be planted in regions where they will be protected from the wind, as their big leaves are vulnerable to harm.
- After a few weeks, roots and sprouts should appear, with mature sizes reaching up to 25 inches tall.
- Caladiums can be mixed with other plants in the same pot, but they must all have the same light and water requirements.
- To add some colorful beauty to mixed bouquets, pinch off a few leaves during active development.
How long does it take for caladium bulbs to grow?
Caladium bulbs can take anywhere from two to twelve weeks to germinate, depending on the variety you choose. They thrive in hot temperatures, therefore the warmer the ground and air temperature when you plant them, the faster they will grow.
Do caladiums come back every year?
Caladium plants (Caladium spp.) grow from bulbs and are hardy in USDA zones 9 and 10. The bulbs will return each year in warmer climates. Because cold weather can easily destroy the tubers, you can dig them up for the winter and transplant them in the spring.
How do you plant caladium bulbs in pots?
- Begin with a huge planter with drainage holes in the bottom, at least 18 inches wide and deep.
- Remove the caladium plant from the nursery pot with care. Shake the roots loose and, if they’re too long, cut them. Make a well in the center of the planter a few inches deep and nestle the caladiums in.
- Begonias and petunias can be added to the mix. Fill up the gaps with potting soil and water in the plants.
Caladiums prefer filtered sunlight, but only for four hours per day. Some cultivars will tolerate more sun than others; when choosing types, make careful to check the plant tag.
This is one of the benefits of container gardening: you may move the pot in and out of the sun until the proper quantity of light is obtained.
Which end of a caladium bulb is up?
Caladium bulbs have a smooth bottom side and a knobby top side (these are the eyes or growth points). Plant right side up. Though they will grow in either direction, planting them with the top side up will result in the quickest sprouting period and the happiest plant.
