I bought young annuals and veg. Answer this question. We planted a variety of white caladium a couple weeks ago under an oak tree and, following the suggestions of one of the websites, we watered them with Miracle Grow. Haven't seen any caladium sprouts but some hidden acorns seemed to be sprouting. Do we need to be more patient? The oak is still shedding leaves, dropping pollen strings or whatever they're called and just yesterday and the day before the weather dropped to nearly 40F--in southeast Texas!

Use a garden fork to lift them from the soil gently. Keep leaves attached, remove soil and wipe clean with a soft brush or cloth. Let the leaves dry for two weeks until they have become completely dry and turned brown. You can then pull the dried leaves from the tuber.
Store clean, dried tubers spaced apart from one another in a cool place in a paper bag, cardboard box or other breathable material. Do not use plastic bags or other airtight storage that traps moisture. A warm garage, pantry or storage closet with ambient temperatures are good choices. Give them room for air movement. If you have a hard time telling what side is up or down on the tuber, mark the tops with a permanent marker before storing.
Plant caladiums in the spring when the soil warms to at least 65 degrees and days begin to warm. This is typically April in Louisiana. If you want to give your plants a head start, plant them indoors in late February or early March in a warm, sunny window. Caladiums also do well in containers on shaded porches, patios and decks to decorate your outdoor sitting areas with a little pop of color. Use the strap-leaf caladiums in sunny areas such as window boxes and hanging baskets.
They, of course, make a striking display as a border in landscape beds and to line walkways. Then, shaking off any loose soil, you can store them in trays of dry compost, or wrapped in a layer of newspaper, in any dry, dark and frost-free place. A garden shed or garage would be an ideal location to keep them snug through the winter. Those grown in pots can be moved into your home to enjoy indoors as the cold season sets in. With excellent tolerance to lower light levels, they make a fabulously exotic houseplants!
They will relish the consistently warm atmosphere your home and can be encouraged to stay in leaf for far longer than those grown outdoors. Alternatively, a shelf, counter top or a small table near to a window will be a great spot for your Caladium plant.
This applies to houseplants too which still rely on natural light through the window which contains the required red and blue elements of the light spectrum.
If it feels dry to the touch, then go ahead and water. Carefully choose where you locate your plants, first of all. The kitchen is often the hub of any home, and always has plenty of moisture in the air from cooking and boiling the kettle.
Why not use this space to create a vibrant display of potted Caladiums that will be a talking point for any visitors, and a colourful backdrop to family mealtimes? Alternatively, the bathroom provides ample humidity to keep these rainforest plants happy — imagine chilling in the bath amongst your own personal jungle of lush foliage! You can grow Caladiums in other areas of the house too. A handy trick to keep humidity levels high in other areas of your home includes using a mister or spray bottle — a good spritz daily will keep your Caladium blissfully happy.
For a lower maintenance option, a shallow saucer of water, perhaps with some ornamental pebbles, provides the same effect. As the water gently evaporates, it provides a little extra humidity to help it along. Inspired to give these wonderful foliage plants a try? Take a look at our full range of colourful Caladiums here! Water when the soil seems dried out, and maintain a steady humidity level.
The quality of a caladium bulb does have a bearing on the size and fullness of the plant. A top-quality bulb is sized at between 1. Larger bulbs have more buds and, therefore, will produce bigger plants. However, smaller bulbs are not considered inferior. They are just going to make smaller caladiums.
Once your bulbs have sprouted, you may want to plant your caladiums in containers and pots. Select containers with plenty of drainage holes and lots of room for growth. Ideally, you want to find pots at least 18 inches 45 centimeters deep and wide. Caladium bulbs can regrow and return from dormancy year after year with proper care.
However, the lifespan of a blooming caladium is about days from when it starts sprouting to the end of the season. Caladium bulbs sprout best when planted about two inches deep.
This allows heat to reach them and they are close enough to encourage the sprouting process. If you are in a cooler climate, you can add mulching to ensure the soil stays damp and encourage heat retention.
Fertilize sparingly beyond the initial mix and add bone meal to help encourage root growth. You can also add a dash of Epsom salts for a magnesium boost to the tubers as they grow. Simply dissolve some in the water you will be giving, but take care not to overdo it.
Instead, ensure they have sufficient heat and humidity. Water sparingly to promote growth and limit the chances of your bulbs rotting. If the soil temperature is too cold or there is too much moisture in the soil, your bulbs will not sprout.
