Elephant Ear culture is rather simple. Keep in mind the mantra : more water = more plant. Within their naturalized habitats, they are able to grow in fairly moist sites or perhaps in drier sites. Home gardeners can grow potted Colocasia esculenta cultivars in shallow physiques water, but other species for example C. gigantea need partial drainage. Colocasias are moderate bird feeders as well as for top performance require either regular fertilizer, or wealthy organic soil with lots of composted material.
Farmers who don’t fertilize or water heavily won’t begin to see the full-sized potential of the plants (which might be fine in some instances). Within the Raleigh, NC area, they’re grown in the earth or perhaps in containers. Some cultivars cannot tolerate strong sunlight and should be grown in shade. However, others will thrive entirely New York summer time sun. Northern farmers can grow most cultivars entirely sun but farmers within the extreme southern U.S. should grow Colocasia in medium to light shade. Colocasias like sandy loam soils having a pH of 5.five to seven. having a layer of mulch on the top. Elephant ear corms ought to be grown two to four deep.
Northern home gardeners (Zone 6 or north) will have to bring elephant ears inside before freezing weather. They are able to grow elephant ears inside just like a house plant, or permit them to go dormant and keep corms inside a awesome place where they’re not going to desiccate. Feed gently and don’t over water and still provide lots of humidity and vibrant strained light. Types of Colocasia that form large corms, for example C. esculenta, could be dug up and also the corms saved in peat moss moss for that winter. They should be stored inside a dry, awesome, but above-freezing location.
Don’t store within an airtight container which might allow moisture to construct, leading to the tuber to rot. Remember to label your tubers! Colocasia gigantea Thailand Giant Strain ought to be stored in active growth throughout the very first winter. Since Thailand Giant is slow to build up an subterranean tuber, it can deplete its reserves if permitted to visit dormant when still a youthful plant. Reduce basically the very best two leaves, then take the pot inside (if it’s in the earth, search up and put within an properly-sized container) and put inside a awesome area in which the plant receives vibrant but strained light.
Don’t over water during the cold months time because the vegetation is semi-dormant. If you reside in a temperature zone that’s marginal for a few of the less cold sturdy species (zone 7b to 8a) for example Thailand Giant Strain, you need to have the ability to overwinter it inside your garden after its second growing season. Following the first frost, encircle the bottom of the guarana plant having a 3 feet diameter cage of hog wire and grow it with shredded leaves. (If left unshredded, the leaves will pack together and hold undesirable moisture from the plant, leading to it to rot.) When new leaves emerge in spring, it is time to get rid of the cage and filler.
Throughout the summer season Colocasias will constantly produce new leaves and also the older leaves will constantly die out. Farmers may wish to periodically take away the dead leaves to be able to avoid the leaves from covering your ground-cover plants and also to keep your garden searching tidy. Some home gardeners might be responsive to the juices of cut Elephant Ear stems (that have calcium oxalate) and could notice some skin or eye diseases unless of course they put on mitts or clean their hands right after contact.
