Monstera: Greenhouse Plants
T – tropical, minimum of 18°C (65°F)
W Indies, Tropical America Splendid; Monstera deliciosa, the most well known, is the Swiss Cheese Plant from Mexico. Tropical temperatures are necessary for these to grow well and produce really huge glossy green leaves with indentations and holes. It is not really feasible to grow them in a small greenhouse but in a large humid tropical house they will grow much as they do in the wild; climbing up pillars and easily attaining heights of 4.5 m (15 ft) or more. Aerial roots will grow in profusion and hang down, often rooting into the greenhouse floor. These roots are produced in the wild to help the plants climb up the trees. The roots cling to the bark of trees and search out moisture and leafy caught in niches high up in the branches. Occasionally they are a nuisance when they invade other plants and some can be cut off without doing any harm to the plant, especially if it has a good root system inside its pot. Propagation is by taking sections of stem each containing two leaves. Cut above the top one and below the bottom one which is then cut off. The cutting should be inserted into a pot of cutting compost and left to root in a warm humid place. Plants will occasionally produce flowers and edible fruits which have a pineapple flavour. Seed is best germinated at a high temperature, 24-26°C (75-80°F).
