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.
How long does it take for a caladium bulb 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.
Should I soak caladium bulbs before planting?
It’s critical to keep the soil warm and moist. Wait until the soil temperature rises around the first part of June before planting caladium bulbs immediately outside. Soak the bulb for about an hour in warm water before planting it bumpy side up, 2 inches deep in the garden.
Are caladium bulbs easy to grow?
With correct caladium care, growing caladiums is simple. The multicolored foliage of these tropical-like plants, which can be green, white, red, or pink, is popularly planted. Caladiums can be planted in pots or in large clumps in beds and borders. Caladiums come in a variety of leaf shapes and sizes, depending on whether they are fancy-leaved or strap-leaved. All of these elements have the potential to make a strong statement in the landscape.
Will caladium bulbs multiply?
Caladiums grow from bulbs and can be replanted year after year. They are generally treated as annuals because they are short-lived as perennials and do not endure cold conditions.
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.
What month do caladiums come back?
The more “eyes,” or growth points, a tuber has, the bigger it is. These tubers will develop into larger, fuller plants as they mature. Potato tubers are consumed for their carbohydrate energy source. Caladium tubers supply energy stores for tubers to go into winter hibernation and grow again in spring when the days lengthen and soil temperatures rise in the correct hardiness zones, just like potato tubers do when we consume them.
Do caladium bulbs need sun to sprout?
- After all threat of frost has gone and daytime temperatures remain over 70 degrees, plant caladium bulbs outside. Caladiums are tropical plants that cannot withstand frost and emerge only when the soil temperature is warm.
- Turn the soil under to a depth of 8 inches to prepare the bed. Remove any clumps of grass or stones using a rake.
- Most plants thrive in soils that have been treated with organic materials. Compost is a beautiful form of organic matter that can be added to your planting area at any time and has a nice mix of nutrients and a perfect pH level. If compost isn’t available, top dress the soil with 1-2 inches of organic mulch after planting, which will start to decompose into compost. A soil test after the growth season will reveal what soil amendments are required for the next season.
- Bulbs should be spaced 8-12 inches apart. Because these are the growth points, the knobby side should be facing up.
- Before all risk of frost has passed, caladium bulbs can be started inside 6-8 weeks. Because they need warm soil to emerge, consider using a heat mat.
How to Grow
- During the caladium growing season, keep weeds at bay. Weeds compete with plants for water, space, and nutrients, so keep them under control by cultivating them regularly or using a mulch to keep their seeds from developing.
- Mulches also aid in the retention of soil moisture and the maintenance of consistent soil temperatures. For annuals, an organic mulch of crushed leaves gives the bed a natural aspect while also improving the soil as it decomposes. Mulches should never be placed on a plant’s stems to avoid decay.
- During the growing season, keep elephant ear plants well-watered, especially during dry spells. During the growing season, plants require roughly 1 inch of rain every week. To see if you need to add water, use a rain gauge. Watering with a drip or trickle system that provides water at a low pressure at the soil level is ideal. To avoid disease concerns, water early in the day using overhead sprinklers so the foliage has time to dry before nighttime. Maintain a moist but not saturated soil.
- A mild fertilizer can be administered after new growth appears. To avoid burn harm, keep granular fertilizers away from the plant crown and foliage. Slow-release fertilizers should be applied at modest rates, as greater rates may induce root rot. A granular fertilizer applied every 2-3 weeks is beneficial to caladiums.
- Pests and illnesses should be kept an eye on caladiums. For pest management recommendations in your area, contact your local Cooperative Extension Service.
- To retain the plant’s strength, many gardeners cut any flower stalks that grow.
- Caladiums are only hardy to zone 10 in the United States. Dig up the bulbs with the soil and tops adhering to them in other spots in the fall before frost or when the foliage begins to die back. Allow bulbs to dry indoors, away from direct sunlight and with plenty of air movement. When the leaves are readily pulled away from the bulb, shake off the soil but do not wash them. Dry peat moss, perlite, or vermiculite can be used to store bulbs. Avoid storing the bulbs below 60 degrees Fahrenheit.
How often should caladiums be watered?
Caladiums prefer evenly moist soil; however, it should be damp but not soggy. When the top inch of soil on your Caladium is dry, water it thoroughly once a week. Caladiums thrive in excessive humidity because they are tropical tuber plants.
Can you grow caladiums in pots?
Caladiums are easy to raise from tubers, which can be obtained in the Garden Center in the spring with summer-blooming tropical bulbs. Place the tubers in a potting mix container, water regularly, and fertilize every two weeks. These can be grown in pots or in a garden bed.
How deep should you plant caladiums?
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.
