Zamia - Zamiaceae - How to care for, cultivate and make Zamia plants bloom
HOW TO GROW AND CARE FOR OUR PLANTS
There Zamia is a beautiful evergreen plant with succulent leaves that forms very showy and very ornamental bushes.
Species: see the paragraph on "Main species"
The genre Zamia of the family Zamiaceae, includes a small group of plants native to Central America, Florida, the Caribbean, southern Georgia (USA) and the northern part of South America. It is a plant that has a posture similar to a palma and the fact that it belongs to the order of the Cycadales, makes it one of the oldest still living plants (it is in fact the same order in which we find the most famous Cycas).
They are plants that take on the appearance of real bushes, characterized by a short stem which in some species remains underground and can reach tremetri and more in length. The leaves are succulent, shiny and waxy, pinnate and have an evident central rib, mostly with smooth margins, although there are species with toothed or serrated margins.
They have the particularity of being dioecious plants that is to say that there are "male plants" and "female plants" that is, plants that bear only female flowers and plants that bear only male flowers.
There are about 35 species in the genus Zamia among which the most common are:
There Zamia furfuraceais a plant native to Mexico. It has a slightly developed stem, partly underground, without branches, succulent that develops up to one meter, with a creeping posture that brings numerous pairs of leaves. When ripe they take on an olive green color and are covered with a reddish hair. The seeds are very poisonous.
It is a plant quite resistant to low temperatures as long as, if grown outdoors, the trunk remains buried. Conversely, it can be successfully bred in marine areas and resists prolonged periods of drought without major problems.
It is also known as Mexican cycas.
There Zamia pumila native to the Caribbean areas, it forms numerous underground very branched stems. It has leathery leaves of a beautiful deep green color very similar to those of ferns.
There Variegated Zamia it is characterized by very large green leaves with yellow streaks, hence the name.
They are mostly plants with warm climates even if the Zamia they adapt quite well to different pedo-climatic situations.
They can be grown both in full sun and in partially shaded areas even if the optimal position is good lighting but not direct sun.
Periodically wipe the leaves with a damp cotton swab. Do not use foliar polishing agents.
During the period of active growth, from spring and throughout the summer the Zamiathey should be watered generously. During the other periods, just enough to keep the soil from drying out.
TYPE OF SOIL - REPOT
There Zamia it needs a soft and well-draining soil as it does not tolerate water stagnation.
It is only repotted when the pot has become too small to house the plant.
From spring and throughout the summer dilute in the watering of the Zamia, once a month a good fertilizer, halving the doses compared to what is reported in the fertilizer package.
It is advisable to use a fertilizer that in addition to having macroelements such as nitrogen (N), phosphorus (P) and potassium (K) also has microelements such as iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), boron (B), molybdenum (Mo), all important for proper plant growth.
They are plants that cannot be pruned. Only the leaves that dry up or get damaged are eliminated to prevent them from becoming a vehicle for disease.
Plants can be multiplied by seed or leaf cuttings.
MULTIPLICATION FOR TALEA
In autumn, leaves are taken and buried vertically in a composite of peat and sand in equal parts. The soil is always slightly moist and the next spring the new seedlings will develop.
PARASITES AND DISEASES
They are not plants that are particularly prone to diseases.
Some species of the genus Zamia their roots are rich in starch so that they are crushed and used for food purposes.
There Zamia pseudoparasitica it is a species that grows on tree branches like an orchid.
