Orchids can be an amazing addition to your indoor landscape, but unfortunately they have a reputation for being finicky and difficult. While they do require precise care, if you know what their needs are, you can easily grow a variety of beautiful orchids and enjoy their exotic loveliness throughout the year. To care for orchids properly…

• Provide Good Light
  Orchids need at least 6-8 hours of bright indirect light or morning sun. Light is the key with growing orchids – without enough proper light, an orchid may live 20 years but never rebloom.

• Increase Humidity
  Orchids are tropical and some varieties require from 65-75 percent humidity. The plant can sit on pebbles in a water-filled tray that is kept filled up as it evaporates. Grouping orchids can also improve their collective humidity.

• Adjust Temperature
  Ideal orchid temperatures vary depending on the type of orchid and the time of year. Warm orchids require 55-65 degrees temperatures at night with daytime warmth reaching 75-85 degrees. Cool orchids need the same night time temperatures, but only 65-75 degrees during the day.

• Water Appropriately
  Water the plant every 5-7 days in the sink, as the growing medium has fast drainage. Smaller orchids may need watered every 3-4 days. The water should be room temperature and without any additives other than fertilizer.

• Fertilizing
  Use a Blossom Booster fertilizer with every other watering while in bloom. When not in bloom, use 30-10-10 fertilizer every two weeks.

• Repotting
  Use only a potting mixture designed for orchids. These mixes are made up of different size fir bark pieces, perlite and even charcoal. Repot your orchid when it is nearly overgrown with roots and is not in bloom. This will average about every 2-4 years.

• Resting Period
  After blooming or producing new growth, most orchid varieties go into a rest period. Reduce the watering slightly and maintain good lighting to allow them to reenergize.

Blooming Orchids

Each type of orchid requires different conditions to bloom (example: Phalenopsis need 6 weeks of cold nights). When you achieve that delicate balance and your orchid bursts forth with a delicate bloom, make sure you do not change your cultural practices or the plant will abort the buds. Even a small change in humidity, temperature or light can cause the plant to abort its bloom, but when you keep the conditions stable, you’ll enjoy the reward these exotic flowers offer.

Have your houseplants been looking dingy and dry no matter how much you may water them? Have they lost the lustrous glow their foliage first had when you got them? Poor humidity may be the cause. Many of our houseplants hail from the tropics and grow in humidity of 50-80 percent, considerably more humid than typical homes. The trick is to know your plant’s preferences and be able satisfy it. Putting a cactus in the shower will cause it to rot, while a fern is perfectly happy.

But what can you do if you really want that fern in the family room where the humidity may only be 20 percent in the winter? If your plant has brown leaf tips or margins it probably needs more humidity and is asking you to increase it. Luckily, it’s easier to add humidity than it is to take it away.

Easy Ways to Increase Humidity

There are several ways you can easily increase the humidity around your houseplants. If they only need the air a little more humid, just one technique may be sufficient, but if they are humidity-loving plants, you may want to try several options at once to really give them a humidity boost.

• Pebble Tray
  Place an inch of small pebbles, marbles, shells or gravel in a 2″ deep tray, half fill the tray with water and set your plant on the pebbles. Don’t set the pot in the water, as the wicking action will saturate the pot soil and could lead to rotting roots and overwatering. As the water in the tray evaporates, it increases the humidity immediately around the plant. When you water the plant, pour out the water from the tray to prevent mineral buildup, algae and insect growth.
• Plant Grouping
  Rather than spacing plants throughout the room, group them together to take advantage of the moisture each plant produces through transpiration. Grouping plants can increase humidity by as much as 15 percent. Place the entire group on a pebble tray if additional humidity is required. Allow air circulation between the plants by ensuring the plants are not touching each other, and rotate individual plants periodically to encourage straight growth and distribute humidity absorption.
• Misting
  Use a misting bottle daily to increase humidity and cleanse leaf pores, which tend to clog with dust. However, to prevent leaf rot, do not mist plants with “velvety” leaves such as African violets. Do not over-mist plants to the point where their leaves are dripping wet, or else they may suffer from overwatering.
• Humidifiers
  Available in a variety of sizes, humidifiers increase the humidity in a larger space. You may also find yourself breathing better when using a humidifier. Our houses become very dry in the winter because of furnaces, heat pumps and fireplaces, and humidifiers can not only help houseplants, but can also help alleviate dry skin, limp hair, chapped lips and hacking coughs.
• Terrariums
  If your house is just too dry for the plants you would like to grow, try planting them in a terrarium. These nearly enclosed vessels create miniature environments perfect for humidity-loving tropical plants such as ferns, orchids and mosses. You will still need to water your terrarium, but because much of the moisture is trapped, the humidity in the enclosure is much higher.
