The 23rd Annual Spring Garden Show in South Coast Plaza presents a seminar about growing orchids. The guest speaker, an expert on orchids, explains the basic needs of orchids as he teaches the audience how to successfully grow healthy orchids.
Ninety percent of all orchids are air plants. But they also need water and sunlight. They have one of the largest families, comprising of about 30,000 different types of species and 100,000 hybrids. He advises the audience not to overwater an orchid. It only needs to be drenched because it just needs moisture. If water gets into the crown, then the orchid will die. Moreover, orchids don't like direct sunlight. But it still likes to be in the sun for a long period of time as long as the sun isn't strong. The orchid's leaf should be hard. If it is soft and wrinkled, then it didn't get enough moisture.
If you unfertilized an orchid, then the plant and/or flower will become smaller as well as the flower color will be less intense. He advises the audience to give the orchid a small amount of fertilizer, on a more frequent basis, as you monitor your plant.
To inspect the roots, pull off everything to clean it, and repot it into a fresh mix. If you over-pot a plant, then the plant will create more foliage as well as a reduction of the amount of flowers. Use white sponge rocks or coconut husks for air circulation.
Moreover, ants farm aphids, and these aphids can kill the orchid. He advises to use a mixture of seventy-percent organic oil to thirty-percent rubbing alcohol solution, such as Neem Oil, to spray the plant, flowers and roots in order to successfully kill these pesky aphids. If there is a brown spot on one side of the leaf, then the plant is sunburnt. An organic dishwashing detergent, comprised of soap and water mix, can be sprayed on the plant. If both sides of the leaf have a brown spot, then the plant has a virus. Cut out the spots and put some cinnamon, which is a natural fungicide, on the plant. The plant's roots should be a white color with nice tips. You can place some sponge rocks into a new pot with the plant, and then carefully press down on this plant in order to ensure it is steadily planted in the pot.
Furthermore, a Vanda orchid should be watered until its roots change color. Since this orchid is an air plant, you can either hang it with a wire hanger and spray it with water, or plant it with coconut husks inside a pot and water it. It is important to remember that this orchid needs air and water as well as its roots need humidity. But don't let the roots have contact with water.
