You might have asked, "How much water should I give my plant?"

This is by far, the most-often-asked question I get as a professional horticulturist. It's also one of the hardest to answer, because of the many variables involved. But I really disliked not being able to give very earnest, wanting-to-be-successful gardeners a good answer so I set about to find an easy-to-convey answer and here it is. 
First off, if the plants are getting water everyday it is too much. Waaaay too much. You're probably not doing this yourself, but if you know someone who is, tell them to Stop!!(wink wink) Plants given daily water will most likely die from too much kindness, TLC, from perfectly good intentions. Fear not, there is help!

This is a generalized rule for normal plants, under normal circumstances (See? There are those pesky variables again.) "Normal" in this case means not rootbound (large plants which are in too-small pots and whose roots fill the pot volume {more on roots and pot volume in another post}) and not in full, hot sun. 

So, here's the hot tip: if you keep the plant's soil moist, like a well-wrung out (dish) sponge, there shouldn't be any problems with underwatering or overwatering. 

Here's the other secret to watering plants that if you follow, for most plants, will always serve you well. If a plant looks to be wilting and its size makes it easy to lift, pick it up and feel the weight of the soil heaviness within the pot: if it's heavy &/or has been sitting in a pool of water, it's too wet and you should let it dry out. If however, the pot and soil feel light and it's wilting, it's most likely too dry and needs water. 

If you try these methods, they should lead to greater success in gardening. Let me know how it works out.
