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 late can I plant caladium bulbs?
Germination can be slowed by hot days and cool nights. Caladium bulbs can be planted outside safely if the nighttime temperature is constantly above 65 degrees. Caladium germination times can range from two weeks to more than twelve weeks. Once again, the “warm thing” in terms of temperatures must be emphasized in terms of planting dates. The faster your caladiums begin to put on a show, the hotter the air and ground temperature are when you plant. The approximate germination times are listed here, as well as some common gardening opinions.
Should you soak 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.
Do caladiums come back year after year?
Caladiums are perennial plants that grow from bulbs and can be replanted each year. They are generally treated as annuals because they are short-lived as perennials and do not endure cold conditions.
When can I plant caladiums outside?
Caladiums are tropical plants that come in a wide range of colors and patterns. They are native to the Amazon River’s banks in South America. Caladiums look great in pots, hanging baskets, and landscape mass plantings. Red, pink, and white are the primary hues, and each variety of Caladium has its own distinct and interesting color combination of two or more of these colors.
Where to plant caladiums
Caladiums grow well outside in the summer and offer a luxuriant, exotic accent to your yard or garden. The majority of Caladiums prefer to grow in the shadow or partial shade, however certain kinds are more sun resistant (see the caladium catalog page) and can be planted in places with little shade. They’re a terrific way to brighten up shady spots. They’re frequently utilized as border plants, along the sides of houses, or in flowerbeds. They make beautiful patio container plants and can also be utilized in window boxes.
When to Plant Caladium Bulbs
Caladiums are tropical tubers that need to be kept warm to thrive. It is crucial to wait until your soil temperature reaches or exceeds 70 degrees Fahrenheit before planting your caladiums. Germination will be greatly delayed if the weather is cool. On the map on the left, you can see the recommended planting date for your area.
What month do caladiums sprout?
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.
Which way do you plant caladium bulbs?
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 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.
Do caladiums like sun or shade?
Caladiums thrive in shaded areas of the yard and garden. They thrive in full to partial shade in southern climates. Most caladiums can be grown in the sun in northern climates if they are given enough water and their leaves are shaded during the warmest portion of the day.
Can you leave caladium bulbs in the ground over winter?
Caladiums tolerate a lot of shade, and some cultivars even do well in full sun, but they grow best in part-shade to part-sun in organically rich soils that are kept equally moist.
Your caladiums should have produced nice-sized tubers by this time, as big as or bigger than the ones you planted, if you gave them the growing conditions they prefer this summer.
These tubers are worth conserving since they can be used to develop caladiums the following year, whether they are left in the ground or saved and replanted.
The tubers may have lost ground over the summer if the growing conditions were not optimal, especially if they were growing in dense, heavy shade or in dry conditions. They may also be too little to perform well next year if the growing conditions were not right. If this is the case, you may want to toss them out and replace them with new tubers next spring.
If the bed where the caladiums are planted is reasonably undisturbed and drains properly, you can just leave the tubers in the ground. This winter, keep the area mulched to protect the tubers in case of extreme cold. They will live and come back up next year because the earth here does not freeze.
The tubers may decompose in the cold, moist soil if the bed stays wet over the winter. It would be advisable to dig and store them in this situation. Heavy rains in December ruined a number of the tubers that had been left in the ground a few years ago. Many gardeners in the New Orleans area discovered that caladiums that had been dependably returning for years did not return the following spring.
The tubers should be raised and removed if you wish to replace the space with cool-season bedding plants like pansies. This will allow you to prepare the bed for the new bedding plants.
When the leaves turn yellow and most of the foliage looks “weary” and falls over, it’s time to dig caladiums.
Do not wait until the entire foliage has turned yellow or brown. The foliage will vanish before you know it, and you’ll have a hard time discovering the tubers. This increases the likelihood that you will accidently dig into and damage the tubers when digging them up, as well as the likelihood that you will miss some tubers and leave them behind.
Caladiums are commonly dug between late September and mid-October. Caladiums planted later in the season tend to stay longer in the landscape, according to my observations.
Lift the tubers with a shovel or a garden fork, being careful not to injure them. Leave the foliage on the tubers, shake and brush off the soil, and put them out to dry in a rain-free spot (such as a garage or under a carport). You can alternatively store them in a bucket or large pot, tubers down, to save space while they dry. Don’t cram too many of them in.
Allow the tubers to dry until the foliage appears to be tan and papery. This usually takes between 10 and 14 days. The foliage will readily detach from the tubers at that point, leaving a healed scar.
After that, the tubers can be cleaned in water. Brushing them off is sufficient unless there is a significant amount of soil sticking to them. If the tubers are washed, they should be air-dried for several days in a well-ventilated area until the moisture has evaporated from the surface.
They’re ready to store for the winter once they’re dried. Any tubers that look to be rotten or have soft patches should be discarded. Tubers that have been harmed accidently during digging can be rescued if they have healed well and feel substantial.
Fill an old nylon stocking, a mesh bag (such as an onion or crawfish sack), a paper bag, or a cardboard box with the healthy tubers. The container should be able to “breathe,” according to the concept. Do not keep the tubers in a plastic bag since they will decay.
Make sure the tubers are kept in an indoor setting with temperatures above 70 degrees. Occasionally inspect the tubers and discard those that show indications of decay or have shriveled up.
It’s a good idea to keep track of the different sorts of tubers you’re cultivating and keep them separate while drying and storing them. This will allow you to set groupings of individual colors where you want them to go next year in the landscape. It’s a good idea to write the name of the cultivar and the color of the tubers on the bags in which they’ll be stored. If you don’t know the cultivar name, at the very least label the tubers by color.
Caladiums produce small, weak tubers in poor growing conditions, particularly in areas of heavy shadow, and these tubers may not return well, whether left in the ground or dug and stored.
How do you fertilize caladiums?
Caladiums thrive in the shady understory of open, high-branched trees. In full shade, they will do pretty well, but the color may not be as vibrant. Caladiums have traditionally required shelter from direct sunlight for optimal development and color, but some of the newer cultivars may tolerate a few hours of direct sunlight every day. When cultivated in the sun, most pink-leaved caladiums turn brownish and burned.
Caladiums prefer damp, warm soil. It is preferable to have a minimum soil temperature of 70°F. Cool soil temperatures cause tubers to decay before sprouting if they are planted too early in the spring. Some gardeners choose to start tubers inside in a shallow flat or flower pot with damp peat moss or potting soil. Cover the tubers with just enough soil and place the container in a warm, well-lit area. Tubers should be started indoors four weeks before being planted outside.
Caladiums should be planted in well-drained soil with a pH of 6.0 to 6.5 for optimal growth. To improve soil aeration, drainage, and organic matter content, add a 2- to 3-inch layer of pine bark mulch or compost to the soil. Unless the soil is thoroughly aerated, root and leaf growth will be limited. Add a complete fertilizer, such as 8-8-8, at a rate of 1 to 2 pound per 100 square feet of bed area (2 tablespoons per square foot). Small tubers should be planted 2 inches deep and 8 inches apart, while giant tubers should be planted 12 inches apart. From the top of the tuber, both roots and shoots emerge; place the knobby side up.
To conserve moisture and keep the soil cool, mulch with a 2- to 3-inch layer of organic material. Leaves with more green color and less of the highly sought, vivid colors may result from soil temperatures above 85°F. Nitrogen fertilization at high amounts can have the same effect. Caladiums are heavy feeders of potash and phosphate, and they require enough of moisture and fertilizer throughout the summer to produce healthy tubers for the following growing season. During the growing season, use 1 tablespoon of 5-10-10 fertilizer per square foot every 4 to 6 weeks. Use a heaping tablespoonful for individual plants; a level teaspoon per pot for plants grown in containers. Allow no fertilizer to come into contact with the leaves. To avoid fertilizer burn, water properly after fertilizing. Caladiums are drought-resistant and need to be watered frequently.
Plants will occasionally produce a bloom that resembles that of a Jack-in-the-Pulpit or a calla lily. The flower pulls energy away from the leaves and reduces tuber size, thus most home gardeners choose to remove it.
