The oxygen explanation regarding plants in standing water is too simplistic. When you root cuttings in plain water, there's nothing else in there compared to what's in soil. Your cuttings may take up to six weeks to root, and in that time, you may top up the water with more clean water occasionally to keep the base of the cutting in the water, while it ...

Well, basically, the perched table is the saturation point, where the capillary action in the soil is canceled out by the force of gravity. Every type of growing media has a different perched table. Capillary action will pull water up from a certain point, and below that point, gravity keeps the water from moving up. The size of the container does not affect ...

Provided that you are feeding the soil/plants the macro and micro nutrients they need there shouldn't be an issue. Epsom salt (1tbsp/gallon) every now and then helps with some of the micro nutrients. Minerals for your plants can be supplemented via plant food, rock dust, azomite or greensand if needed or through the soil/potting mix of the plants unless ...

This plant is Zephyranthes carinata, a bulb with the common name Rain Lily. There are lots of hybrids these days, but the reason they're called rain lilies is because they flower after rain. Some only flower once a year, and that is later in the summer/autumn, when the autumn or summer rains arrive, but some of the newer hybrids flower more often and do ...

I believe I have gathered enough information that an answer is now available. Three main variables determine the direction roots grow: Gravity, light, and water. These are called gravitropism, phototropism, and hydrotropism. Phototropism is simply that the roots grow away from the light. I wouldn't think light extends much below the surface, so this ...

Given the previous answer, which covers hydroponic growing, I'll just add an explanation of how it's possible to over water a plant which is growing in potting compost, and thereby cause plant death or disease. The key is in the word 'clean' - hydroponics requires clean water, principally. When a plant has its roots in soil or compost, this isn't clean in ...

Rust is iron oxide, which does not harm plants in moderate amounts, because it is not water soluble unless the soil ph is very low. In fact, oxidized iron is what gives most red subsoils their color. Watering your plants with this water will not harm them at all. If you suppose there was nothing environmentally harmful in it before (which is NOT a good ...

If the greywater is from food preparation, it's fine to use if it doesn't contain salt, oil, or big pieces of food. I'd use a strainer, to get all the pieces. I think the water from the food dehydrator is fine, if it was used only for plant matter, not animal. So no animal, no salt, no oil, and I'd say if you were baking in the kitchen, don't use rinse ...

You should make sure, before you use the water, that no chemicals have been added for a week (some say half a week), and assuming you've only used chlorine, it should be down to 1 part per million after that time, or even lower, which means yes, you can use it for irrigation purposes. If you can, check the ph, which should be between 7 and 8 before ...

Judging by the new growth being red, I'd say these were Photinia fraserii 'Red Robin'. I can't tell if they're pleached or not, can't see any framework within the foliage, so its possible they're just trained by pruning to this shape. Unless you live somewhere that gets very hot and very dry in summer, they shouldn't need much watering because they have ...

It's not advisable to use this water on potted plants because of the risk of contaminants from detergent and fabric conditioners being present, but many people do spread it round the garden for plants in open soil. Its useful in a steam iron because it contains no lime - also useful for lime hating plants, again in the garden, not in pots. Regarding storing ...

Small fruiting tomatoes tend to be a lot juicier (that is ratio of meaty pulp to juice) than medium or large fruiting. Tomato produces a skin of a certain size for the number of fruits it has, then as b.nota points out extra water arrives. The fruit is already turgid, the extra water has nowhere to go but to burst the balloon. It is particularly a problem ...

There are two main causes of fruit split - the first is irregular watering. Once tomatoes have fruitlets, and especially as they start to get bigger and ripen, its critical to water sufficiently every day, without missing a day or two, or giving a bit less some days than others. If you don't, then the tomato, receiving a sudden influx of water, swells ...

I'd be more concerned about the trees dying from lack of water than the grass which surrounds them, frankly. Have you considered cutting away the grass at the base of the trees and replacing with a mulch instead? A humus rich mulch such as bark chips or good composted material applied in spring, when the ground is moist, would conserve moisture for the trees,...

If you want to write software probably you are looking for customized solutions, you have imagination and you don't mind to do it yourself. I suggest you try search with google: Arduino + Watering ( for example look at this document: THE GARDUINO GARDEN CONTROLLER It is a simple open-source platform with which many hobbyists have already ventured and you ...

The optimum time to water plants is in the morning, before any heat builds up - this gives time for the water to penetrate and be taken up so the plants are already well hydrated. Watering in noon day strong sun means you'll lose some to evaporation before it has much of a chance to help the plant. The next best time to water is the evening, after the heat ...

Contrary to what you often see, Wasabi can be grown in moist, but not submerged, soil. You'll do best starting with fresh, viable seeds. Here's a few points on preferred conditions in soil growing (this does not all apply to hydroponic growing): Soil should be free draining, highly organic soft soil at least 10 inches deep. The soil should not compact ...

I have some experience watering with grey-water collected directly from our household kitchen sink that I'd like to share. First, I'd like to comment that the bacteria from the grey-water should not be any more of an issue than worm, bird, insect or other feces that are a natural part of the soil content, so long at the fruits/veggies are adequately rinsed ...

I planted Palestine Strawberry clover in my yard (Phoenix, AZ) this past fall. My clover seems extraordinarily resilient so far (with the exception of falling prey to our local quail population). Considering clover is considered a difficult-to-remove lawn pest by many, I don't expect you'll have too much trouble getting them established. When I sowed mine, ...

The key thing with any plant in a pot of compost is that the roots must get air (oxygen, actually). Overwatering is the most common error. Stick your finger on the soil surface and drag it across the surface a short way. If it feels wet and soil sticks to your finger, you should not water. An alternative is to use a wooden skewer/stick/chop-stick. Shove it ...

Your tillandsia has been damaged by using chlorinated water. You can dechlorinate water by leaving it to stand for 24 hours but if the municipal authority uses chloramines instead, then you will have to use a dechlorinating solution that you can purchase from a pet shop. Rain water is naturally very soft. You can not use distilled water as that is too ...

I think you overwater the chilli plant. The leaves are not very healthy. Chilli likes also dry climate, so try to water a lot less. One or twice a week. I would also not put so much fertiliser. Once every two or three month should be enough (and possibly one every year, but possibly also changing the soil). Chilli doesn't produce a lot of green, or big ...

These plants like bright but diffuse light ( not direct sunlight ) and moist oxygenated soil but you've already identified that it has been sitting in stagnant deoxygenated water. This has lead to the chlorotic foliage you now see. I presume that you have a pot inside a pot so you can't easily see how much water the pot is sitting in so this might well ...

This is Money Plant, also called as Pothos and has many names. It is easy to grow, requires very low care. Good for new gardeners. It does not requires a lot of sunshine, grows very well indoors with low light. You can practically keep it anywhere, even in water filled bottle. (http://i.stack.imgur.com/LQTxJ.jpg) Water it moderately, just to ensure its soil ...

I'm not an expert on house plants - strictly an outdoor plant grower but here's what I know is for certain: The water in your rubber tree's saucer is evaporating just like it is in all the other plants' saucers. There's just more water there than you think there should be. Now, some questions I would have are: How's the moisture level in the soil ...

Water pumps aren't very expensive if you know where to look -- the submersible pumps for water fountains or hydroponics are often under $20. You may need an adaptor to attach it to a garden hose, or just buy a length of tubing for the pump if you're not going too far with it. The only issue is that they won't drain 100% of the water. They typically have ...

This is not an uncommon problem that appears to be chalked up to a design flaw (check out the amazon reviews). Quite honestly, I can't say I'm surprised. The website says no tools are required. Few things involving residential water pressures are reliable with "hand tight" for very long, so I'm pretty skeptical. If it is leaking from somewhere other ...

Depends on whether, and how much, alkali salts have been added - Schweppes Club soda has sodium chloride, sodium bicarbonate and potassium sulfate added to it. I'd use it on the garden instead, unless you want to do a trial on a couple of plants and see what the results are.

If you're having a drought, I'd say you'll be fine using it for a short period of time. You mentioned adding salt; this will build up in containers every day you use it, and eventually will harm the plant. Don't use for prolonged periods, and dilute it if possible, as far as possible. Pasta water contains residue full of carbohydrates, so the bacterial ...

It's dangerous to use a set amount of water per day, when watering potted plants. This is because they may use different quantities as they get older, and also because it is very easy to overwater, which could be fatal. It's better to water until the mix is wet, and then leave it until the top ½" of soil becomes dry. Use your finger to test this. You ...
