When the majority of the leaves have turned yellow and are starting to fall over, it’s time to dig. Lift them gently from the dirt with a garden fork. Keep the leaves intact, remove the soil using a gentle brush or cloth, and wipe clean. Allow the leaves to dry for two weeks, or until they are totally dried and brown. The dried leaves can then be pulled from the tuber.
Clean, dried tubers should be stored in a cool area, separated from one another, in a paper bag, cardboard box, or other breathable material. Do not store anything in plastic bags or other airtight containers that will trap moisture.
Warm garages, pantrys, and storage closets with ambient temperatures are excellent options. Make sure there’s enough space for them to breathe. Mark the tops of the tubers with a permanent marker before storage if you can’t determine which side is up or down.
Caladiums should be planted in the spring when the soil temperature reaches at least 65 degrees and the days begin to warm up, which is usually in April in Louisiana. Plant your plants indoors in late February or early March in a warm, bright window to give them a jump start.
Plant tubers smooth side down in the landscape at a depth of 2 1/2 to 3 inches and 6 inches apart. Caladiums look great in containers on shady porches, patios, and decks to add a splash of color to your outdoor seating areas.
What month do you plant caladium bulbs?
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 directly in the garden in the spring or started four to six weeks ahead of the average frost date indoors. 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?
- 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.
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.
When can I plant caladiums outside?
Wait two or three weeks following the last frost date to plant your caladiums outside. The soil temperature should be 65-70°F and the nights should be warm. It will be early to mid-June in cool climates. The majority of caladium types may be grown in either full sun or partial shade.
How long does it take for caladium bulbs to 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.
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 long does it take for a bulb to grow?
In any event, the bulbs must first grow roots and establish themselves before sending up top growth, so I believe you will have to wait a lot longer. Glads bloom in 70 to 90 days, and they’re frequently planted in succession over a ten-week period to ensure a steady stream of blooms in the garden.
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 about 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.
What is the best fertilizer for 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.
How cold can caladiums tolerate?
Caladiums can only thrive in warm weather and will die soon if temperatures dip below freezing. Caladiums should only be planted outside after all danger of frost has gone and the soil temperature has reached 70 degrees Fahrenheit. Caladiums can survive temperatures below 70 degrees Fahrenheit, but they will not grow as well or as large. They can withstand temperatures as low as 45 degrees Fahrenheit, but they thrive when the average daytime temperature is above 70 degrees Fahrenheit and the average nightly temperature is above 60 degrees Fahrenheit.
