Elephant Ear culture is definitely rather simple. Just keep in mind the mantra: more drinking water = more plant. Within their naturalized habitats, these people could grow in pretty moist sites or within drier sites. Gardeners may grow potted Colocasia esculenta cultivars in shallow body of water, but some other species such as Chemical. gigantea need partial draining. Colocasias are moderate feeders and for top overall performance require either regular fertilizer, or rich organic ground with plenty of composted material. Growers who perform not fertilize or drinking water heavily will not see the full size possible of the plants (which may be fine within some cases). In the particular Raleigh, NC area, these people are grown in the particular ground or in containers. Some cultivars cannot endure strong sunlight and should be grown in color. However, others will flourish in full North Carolina summer sun. Northern farmers can grow most cultivars in full sun yet growers in the intense southern U. S. ought to grow Colocasia in gentle to medium shade. Colocasias like sandy loam soil having a pH of five. 5 to 7. zero having a layer of mulch on the top. Elephant ear corms must be planted 2” in order to 4” deep.
Northern landscapers (Zone 6 or north) will have to provide elephant ears inside prior to freezing weather. They can grow elephant ears inside like a house flower, or allow them in order to go dormant and shop the corms in the cool place where these people will not desiccate. Give food to lightly and do not really over water but offer lots of humidity plus bright filtered light. Types of Colocasia that type large corms, like Chemical. esculenta, can be dug up and the corms kept in peat moss for the winter. These people need to be held inside a dry, cool, yet above-freezing location. Do not really store within an airtight container which may permit moisture to build, leading to the tuber to decay. Don’t forget to brand your tubers! Colocasia gigantea Thailand Giant Strain must be kept in active development during the first winter season. Since Thailand Giant is usually slow to develop a good underground tuber, it may easily deplete its supplies if allowed to proceed dormant when still the new plant. Cut back again all but the really best two leaves, after that bring your pot inside (if it is within the ground, dig this up and place within an appropriately-sized container) plus place in a awesome area where the flower receives bright but strained light. Do not more than water during winter period as the plants are usually semi-dormant. If you reside in a temperature area that is marginal intended for some of the much less cold hardy species (zone 7b to 8a) this kind of as Thailand Giant Stress, you should be capable to overwinter it in your own garden after its 2nd growing season. After the particular first frost, encircle the particular base of the shrub with a 3 feet diameter cage of hog wire and fill this with shredded leaves. (If left unshredded, the simply leaves will pack together plus hold unwanted moisture towards the plant, causing this to rot. ) Whenever new leaves emerge within spring, it’s time in order to remove the cage plus filler.
During the expanding season Colocasias will constantly produce new leaves plus the older leaves can continually die off. Farmers will want to regularly remove the dead simply leaves to be able in order to prevent the leaves through covering your ground-cover plant life and also to maintain the garden looking clean. Some gardeners may end up being sensitive to the fruit juices of cut Elephant Hearing stems (which contain calcium supplement oxalate) and might notice several skin or eye discomfort unless they wear mitts or wash their fingers soon after contact.
