During their period of rest, caladium bulbs need at least two months before they can germinate again. By storing them properly and providing the necessary conditions, you are ensuring their well-being and setting the stage for successful growth in the following season.
Tips For Growing Caladiums Indoors
Caladiums can bring vibrant colors and tropical beauty to indoor spaces, making them a popular choice for indoor gardening. When it comes to growing caladiums indoors, there are a few essential tips to keep in mind to promote healthy growth and long-lasting beauty.
First and foremost, caladiums thrive in temperatures over 70 degrees Fahrenheit. If a warm spot is not available indoors, using a fluorescent grow lamp or a seed-heating mat set to 70 degrees can provide the necessary warmth for optimal growth. It is also crucial to plant caladium bulbs in pots that provide at least one inch of soil space around the bulb. This ensures that the roots have room to grow and develop.
When planting caladium bulbs in pots, it is recommended to wear gloves to protect your hands. Fill the pot halfway with peat moss or soil-based medium mixed with peat moss, ensuring a depth of at least three inches. Plant the bulb with the bumpy side facing up, and consider adding bone meal or slow-release fertilizer to the soil to provide essential nutrients. Remember to keep the soil slightly moist but not oversaturated with water.
Note: Caladiums can start growing within two weeks if the conditions are right. However, it is advisable to keep young plants indoors until after the last hard frost or transfer them outdoors in June.
Remember to fertilize the plants every week to promote healthy growth and vibrant foliage.

Choosing The Right Location For Planting Caladium Bulbs
When it comes to planting caladium bulbs outdoors, choosing the right location is crucial for their overall health and growth. Caladiums thrive in shade or partial shade, making them an excellent choice for areas in your garden that receive minimal direct sunlight.
To avoid sunburn spots on the foliage, it is essential to choose a shady spot when planting caladiums outdoors. This will prevent the direct and intense rays of the sun from damaging their delicate leaves. Additionally, caladium bulbs should be soaked in warm water for an hour before planting to promote healthy growth.
When planting caladium bulbs, it is important to consider the distance between the bulbs based on their size. Smaller bulbs should be planted approximately six to eight inches apart, while larger bulbs should have a spacing of twelve to eighteen inches. This spacing allows for proper airflow and reduces the risk of disease or bulb death.
To further enhance their growth, applying a layer of mulch around the young caladium will help keep the soil moist. Regularly checking the soil and mulch to prevent drying out is crucial for the health and vitality of your caladiums. Remember to provide adequate water, as caladiums should be consistently moist but not waterlogged.
