Caladiums prefer warm weather and moist soil, so they are typically planted in the spring or summer. However, in some regions, it is possible to plant caladium bulbs year-round. When choosing a planting site, make sure to choose an area that gets partial sun or filtered light. Caladiums can also be grown indoors as houseplants. If you live in a region with cool winters, you can dig up the bulbs and store them indoors until it is time to plant them again in the spring. With a little care, caladiums can bring beauty and color to your garden for many years to come. A larger bulb will sprout more sprouting points called eyes. A healthy caladium bulb should be firm, bonny, and rounded. The best time to plant caladium bulbs is during the spring and fall.
Caladiums like a warm climate, and they are not tolerant of cold temperatures.
Therefore, they are best started indoors and will thrive best if you start them indoors until the summer. It is possible to start indoors, but you should make sure that the temperature does not drop below 60 degrees F.
It is also important to remember that caladium bulbs do not require darkness to overwinter. It is best to avoid using airtight containers, because they will create a lot of heat within them and will cause rot and mold. If you do not keep them in the dark, you may end up with a weaker plant.
Preparing soil for caladium bulbs
When planting caladium bulbs, it is important to prepare the soil properly. Ensure that it is well-drained, but not so dry that the bulbs will be soaked. Incorrectly prepared soil can result in nutrient deficiency and root rot. It is also important to keep in mind the type of caladium you’re growing. Some varieties do better in full sun while others do better in partial shade.
To plant caladium bulbs, you should wait until the last threat of winter is over. If you’re planting them outdoors, wait until the soil reaches 70 degrees Fahrenheit. In addition, caladium bulbs are more difficult to germinate in cool soil. They should be planted at least 11/2 inches below the surface. A layer of peat moss in the soil is ideal, as it improves moisture retention. The soil should be prepared by raking off any weeds and debris that might interfere with the bulbs’ growth.
When to Plant Caladium Bulbs
Caladium bulbs can be planted 6 to eight weeks before winter. You can also start them indoors with a heat mat. During the early stages of growth, caladium bulbs grow best when the soil is warm. After planting, weeds need to be controlled, as they compete with the bulbs for resources. Mulching can help control weeds and also keep the soil moist and even. If you choose to mulch the area, make sure to apply organic mulch. This will help the soil improve with time.
The soil you prepare should be slightly acidic and have a pH of 5.5 or 6. Caladium bulbs can be planted on the flat side of the soil and should be planted at least five centimeters deep. You can purchase caladium bulbs online or at a garden center. Local garden centers can also provide you with guidance on planting orientation. Be aware that imported bulbs may take longer to come out of dormancy.
If you are not confident with your planting skills, you can also purchase a Proven Winners bulb with a painted white surface on the top. This will eliminate the guesswork and ensure that the bulbs are planted correctly. If you’re planting caladium bulbs at an early age, you can remove them from their boxes and place them in a well-ventilated area where the soil temperature stays around 65 degrees Fahrenheit.
Fertilizing caladium bulbs
Fertilizing caladium bulbs before planting can make a huge difference to the quality of your plants. Caladiums are relatively small plants, but they can still produce lush foliage and a strong, upright plant. They’re often sold in a variety of sizes, based on bulb diameter. Larger bulbs also have more energy reserves and will produce more foliage. To get the best foliage production, remove the dominant “lumps” from the bulbs. This can create a more even growth pattern.
Caladium bulbs should be planted two to three inches deep and covered with one and a half to two inches of soil. If they’re growing in sandy soil or in warm climates, they will need additional fertilizer. You may also need to fertilize caladiums regularly during the growing season. Be sure not to over-fertilize them because this will cause them to produce too much chlorophyll. As they mature, caladiums will develop color and become more interesting.
After planting caladium bulbs, it’s important to make sure they’re kept properly moist. Caladium bulbs grow best when planted in rich, organic soil that is well-drained. To ensure the best growing conditions, caladium tubers should be planted one to two inches beneath the soil surface.
Fertilizing caladium bulbs during the spring and summer months is important to keep the plant healthy and thriving. You don’t want to fertilize caladium bulbs during the fall season, as this will interfere with their growth cycle. Aside from disrupting their growth cycle, fertilizing caladiums in the fall will not do the bulb any good.
Caladiums thrive best in warm, moist conditions. You’ll need to keep the temperature of your soil at 65deg F or higher. A little bit of mulch will keep the soil moist and reduce the risk of evaporation. You’ll also need to water the bulbs regularly, in proportion to their exposure to sunlight.
The foliage of caladiums begins to fall down in the fall. To harvest caladium bulbs, dig them up in the fall and store them indoors. You can move them outdoors in the summer if you’re in a warm area. The leaves of caladiums look beautiful when placed in a vase.
Watering caladium bulbs
Watering caladium bulbs is important, because they need to stay moist until they are established. While they do best in full sun, a few cultivars will grow and bloom in partial shade. A pot big enough for the tuber is an ideal size. It is best to step the tuber up into a larger pot when it becomes root bound.
Alternatively, you can plant the tuber in a single six to eight-inch pot, and then bury it in the soil. This method protects the roots and retains moisture better. It also saves backbreaking work, because the tubers can be lifted out of the pots in the fall.
It is important to plant the caladium bulbs no deeper than two inches, as planting them any deeper will delay their sprouting process. It is also vital to keep the soil evenly moist and at a constant humidity level. The plant size depends on the variety of the bulb you purchase. The top-quality bulbs will grow between 1.5 and 2.5 inches (3.8 to 6.3 centimeters) in diameter. But you should be aware that smaller bulbs are not inferior.
Whether you are planting caladium bulbs in a pot or directly in the ground, you need to follow specific instructions for the caladium plant. You should plant the tubers with the right side up so that the top side is facing up. This way, the roots will have enough room to grow and the leaves won’t sprout too early. This is crucial in ensuring the plants will thrive and bloom.
As long as the temperatures are between 65 and 75 degrees F, you can keep the tubers in the ground for the winter. However, it is best to bring them indoors before the first winter in fall. This way, they can stay dry for a few days before they begin to grow again in the spring. Just remember not to water them too much because this will result in rotting.
You should also keep an eye out for signs of sunscald. Usually, plants with this symptom were recently transplanted. This problem is usually caused by overwatering or too much sun. Sunscald affects the chlorophyll in the leaf, which kills the plant. If you suspect the plant is suffering from sunscald, consider transplanting it to a part-shade area.
Overwintering caladium bulbs
In mild climates, caladiums do not need special care or indoor storage during the winter. The foliage dies back and will re-grow in the spring. The best way to store them is in a cool, dry place where there will be no freezing temperatures. It is important not to water them too much during the dormancy period, because water may rot the bulb.
If caladiums are planted in the soil, it is recommended that you cover them before the first frost. Alternatively, you can store them in a pot or container. If you are not storing them in a pot, you can wrap them in newspaper and store them in a dry, dark area. Once the bulbs are dry, you can plant them in the spring.
Before you plant caladium bulbs in a pot, make sure you have adequate soil temperature for planting. Generally, caladiums like a temperature of 70degF, so keep the soil temperature around that level. However, if the soil is too cool or wet, the bulbs will rot.
