In many cases cactus plants that are infested with insects like mealy bugs are very hard to save whether using insecticides or 'green' alternatives. The choices we make about how we deal with insect problems may be as much a matter of our own health as it is saving the life of the plant.he way to get this witch hazel to kill insects like mealy bugs is to take the plants out of their soil and dip the plants in witch hazel for a while. The witch hazel needs to be rinsed off of the cacti with water, then allow the plants to dry and replant them in new soil.
Size and shape of flower depends on the species of cacti and type of pollination. They can be white, red, orange, pink or blue in color. Butterflies, bees, moths, bats and hummingbirds are main pollinators of cacti. Spines of cactus can be used in the production of hooks, combs and needles. Fruit can be used as food.Certain cacti produce substance called mescaline which induces hallucinogenic effects. It has been used by shamans to induce trans-like state and ensure communication with God.ince cacti live in dry areas, they need to absorb large amount of water and store it in the stem and roots for the periods of drought. Besides storing of water, stem plays role in the process of photosynthesis (production of food by using the sunlight and carbon dioxide).
