Orchids Adore Rainwater
We should appreciate orchid and other flower cultivators, at least in part, for the burgeoningpush to reuse the water that reaches our homes, especially that which comes down as rain. If you are an orchid grower orchids, this is something you might want to investigate.
Orchids, similar to other plants, have specific likes and dislikes as to the water given them to nourish their roots. Most of them dislike water that is too hard. Unfortunately, the water that comes out of the taps in many areas is too hard for orchids to respond as well as we might like. Rarely will hard water actually kill them. It might stunt their growth, though, or keep them from ever blooming as beautifully as they would have.
A nice thing about orchids is the fact that they have thick, fleshy roots that can hold up to hard water better than many other types of plants. Hardwood plants, for instance, with their fine roots, are easily destroyed by water that is too hard. Nontheless, you should avoid using hard water on orchid plants if you can possibly avoid it.
You can buy devices that attach to your water line to soften your water while removing various types of unwanted impurities. But really, nothing beats rainwater when it comes to treating orchids right! After all, this is the form of water that nature supplies to plants the world over.
Several companies make rain barrels that are ideal for catching and storing rainwater until you want to use it. Many homeowners set the barrels up underneath the rainspouts coming from their roofs. With some planning and work, you could set up several rain barrels to channel water right to your orchid plants. Then your watering work, presuming you live in a fairly rainy area, becomes virtually hands off.
Whatever kind of water you use, don’t put it on plants if it is chilly. For example, I would not use water taken from an outdoor faucet on a cold day, without first bringing it to room temperature in my home or in the greenhouse. Cold water can result in spots on the plants, rot the new growths and injure the roots.
Some orchids will benefit from water with some lime mixed in it. In years gone by, people noticed that imported Cypripedium orchids often were covered with chalky lime deposits due to the plants having grown in limestone rock crevices where water trickled down upon them. So if you have a Cypripedium, you could try adding lime to the water, a little at first and then more if you determine that the plant is responding well to it.
The art of orchid cultivation is a fascinating subject. Orchid growing is not as hard as some people like to make it out to be, but you must arm yourself with accurate information before plunging in to this rewarding pastime.
The most complete guidebook to expert orchid growing, I have found, is Orchid Care Expert by a Mr. Nigel Howard, which is available to be downloaded from the web. Mr. Howard’s guide is a comprehensive course, helpful for novices as well as more seasoned devotees alike. Additionally, check out this Orchid Secrets web site, which has an ever-expanding database of information on a broad range of topics of orchid cultivation.
