I recently replaced the "finger test" with a good moisture meter...I found that I had in years past been over-watering my hanging pots...and the result was rotting roots. With the moisture meter, I have realized much healthier plants. I acknowledge it is all about the climate you live in but It is amazing that I have reduced my watering dramatically this spring but am sure it will pick up in the brunt of summer.....BUT...I will continue to use my moisture meter to determine: WET, MOIST, DRY before I take action. Thank you for the great article and I hope my "findings" might help others.

Interesting- in general it takes quite a bit of doing to overwater a hanging plant.

This article assumes that people actually go outdoors and take care of their plants on a regular basis, which I really hope is true. I live in one of the world's great horticultural climates, my neighbors have nice lots and at least enough money to pay their outrageous mortgages; within my purview anyway, almost nobody gardens at all, nobody under 60. The dreary synthetic "landscapes" that have almost completely replaced gardens are left to the tender mercies of unskilled laborers, who attempt to bash them into submission mechanically in 15 minutes every week or two. Watering is left to mechanical systems that neither the owners nor the laborers seem to understand any better than they do the plants. To an old gardener, this is all immeasurably sad, not to mention wasteful.

It depends on the plant and the method of giving water used. Using a hose is great if you can control the flow and you have the outside connection, but for those of us you have to physically carry a watering pot, checking the soil is needed even just to make sure that the soil is draining well, especially if you are growing a container garden versus in-ground plants. Soil drainage is important. During the growing season, you should be aware of your plants' needs so they thrive well.

Where can I find a same terracotta pots as it shown on this picture? What’s a name of it? Thank you.

Not bad as generalizations go, but don't let general rules stop you from considering individual situations. On very hot days (it may hit 120 for days at a time where I live) plants may have plenty of water in the soil and not be able to take it up fast enough through their roots. Practically all plants can absorb water through their leaves; spraying with water will cool the plant down and give it some added water- often enough to save it in a heat wave. Wilting plants aren't necessarily lacking water in the soil (though if a plant suddenly wilts on a hot day that's a pretty good guess). It may also be a sign of a compromised root system. This could be caused by gopher damage (or other subterranean creatures- it's usually gophers in my area.) It could be from getting dry enough to shrivel the roots (mostly for small plants and annuals) or too wet, starving the roots for oxygen and promoting fungus growth. Poorly draining soil and overwatering contribute to this. There are also fungus diseases that can plug the vascular systems of woody plants- this can be hard to spot and impossible to cure.
If you're using an automatic watering system, it's important to understand how it works and to check it regularly. These systems are very prone to malfunctions- most often connections coming apart or sprinkler heads falling off, and most people set them for very early morning so they never see the malfunction, which not only wastes water, it can result in no water where you want it and too much where you do. Also, hired gardeners tend to set them for excessive watering to make sure everything is green and lush.

Great advice, smaug! You’re quite a gardening resource. I always learn something from your comments. ;o)

Thanks- I really am trying to be helpful; I realize that some people tend to find my way of expressing myself a bit abrupt. I have been gardening seriously going on 50 years- enough to give me a smattering of information on gardening in a couple of locations 15 miles apart, and a thorough respect for the vastness of the subject.

The same thing occurs in the container plantings, you need to know what's going on with your soil, plus any critter visitors. I specifically changed the types of plants ( I mostly grow perennials) to discourage certain bugs (ants and spiders) and squirrels from digging. Every year gives me a new experience in maintaining the flowering members of my plants because the weather in my area (New York) doesn't follow the pattern for the grow area

Interesting about the squirrels- do you have something to stop them besides having the pot full or covered? Most years here they're just a nuisance for a few weeks in fall; unfortunately that coincides with the time I'm putting out a lot of pots of bulbs- bare soil until they sprout, to the squirrels- and newly repotted plants, and the squirrels go nuts planting acorns in them unless I cover them somehow. This (last?) year produced an acorn crop such as I've never seen, and I still have squirrels digging into my pots in late May. I guess I could grind up a bunch of Habaneros or buy a bunch of Cayenne, but is that any way to live?

Smaug, perhaps you can help me. I also live in a hot dry climate and have been told that my trees need to be watered if I want to keep them in good health. I don’t know how much or how often. Can you give me some advice? I have a regular hose, but should I get a soaker hose?

4376ab "Trees" covers an awful lot of ground. If you're in the western US, the ground water supply this year is severely limited, and plants that usually require no water may need it this year. For most trees, almost all, you want to water deeply, every 4-6 weeks at a guess. As with everything in gardening, there are a ton of variables- soil type, sun exposure, slope etc. There are devices to help- soaker hoses are pretty good; at any rate you want to spread the water around out to the tree's drip line (basically its shadow with the sun straight overhead)- a low sprinkler will do the job, but to avoid evaporation should be done very early, preferably on a day that's not hot or windy. I like to use a "root feeder"- a device that injects the water down 12"-18"; it's made for feeding, but I usually leave the food out; someone probably makes something just for watering- I'm not much of a shopper. There are far too may different trees to go into any detail, but I've found that in normal years trees more than a few years old require no irrigation; however, if you're irrigating anywhere in the yard tree roots will probably find it. By the way, if you leave a potted plant with a drainage hole on the ground- tree roots will likely find their way into the pot, making life very difficult for the plant.Fruit trees are a little different; for good fruit production most will require a fair amount of water. Underwatered citrus will produce scanty, often thick skinned fruit and production will be low with most. Figs do pretty well in hot dry areas, but they will search out water over a wide area. On the other hand, I have an apricot that I never water. It's production wouldn't thrill a farmer, but it turns out more fruit than I can use. Some ornamentals- Japanese Maples come to mind- also will probably need irrigation. If you're taking up gardening and you live in the west, I would recommend Sunset's "Western Garden Book" as an absolutely essential resource, and it could give you some more specific information on your plants. One would hope that whoever planted them chose trees suitable to your area- good luck with it.

Smaug,
What a generous reply! We are in central AZ at an elevation of 5800 feet so the drought factor is high. Our trees are a combination of needles and leaves (that shows you the extent of my garden expertise). I’ve ordered the watering spikes and book from Sunset. I feel that at least I can be giving these trees a boost to help them through the heat of the next season. The garden was in place long before we arrived, but the summers are hotter and drier than ever so a helping hand is in order.
An apricot tree sounds like heaven. Apricot jam, apricot ice cream, apricot tarts; what a luxury! Lucky woman. Thanks for being so kind with your advice.
