No, it is not. Those are nitrogen fixation nodules, similar to what alfalfa roots do. It is the result of symbiosis with a soil bacterium. With root rot the roots die and things get a little stinky. Pinch an affected root with a thumb and forefinger and tug - the epidermal tissues will slide right off the xylem or woody core.

No, you shouldn't interfere with them or damage them in any way, you may compromise the tree if you do. If possible, remove the grass that's near the roots, plant ground cover instead or just mulch around the roots.

If you cut the root you will damage the leaves that are fed by that root. That root also provides structural stability. A better idea is to rebuild or remove the retaining wall in that area. The root will only get bigger and they can move quite large stones and interlock.

I think you're conflating two things - tilling wet soil and jumping straight to 'artificial' soil to create particular conditions for seeds to grow in,but the one doesn't necessarily lead to the other. The statement that tilling wet soil destroys soil structure is accurate, but tilling destroys soil structure whenever it is done, its just worse for seeds and ...

I'm sorry to say it will hurt the tree - over time, as they mature, many trees develop buttress roots at their base, but upheaval around the base of a tree, even without buttress roots, is to be expected. The roots are essential to the tree's survival, and should not be cut, shaved or removed. Perhaps you could replan the walkway to leave space around the ...

Is leaving them in there better or worse than taking them out? In a pot, definitely take them out if you can. They will put out chemicals while decomposing (usually) that slow down the new plants (a kind of allelopathy). In a garden bed, usually this process only takes a couple weeks. Also, in a pot, the roots have the potential to mess with water movement, ...

You don't say what part of the world you're in, and that makes a difference to legal procedures, but if the tree is close enough to damage your house should it fall, here in the UK, I'd advise my buildings insurance company of what's happened, and hopefully, they'd either arrange for a Tree surgeon to attend and assess the situation, or pay for a tree ...

Evil Elf asked in a comment about studies of what does happen to trees when root work is done. A survey of web links shows that root pruning is commonly given as good advice. Academic studies of the results are scarcer. Here is one city that trims roots down on request but notes that "wounds can create an entry way for harmful insects and diseases". The ...

Agree with Jim Young's answer, point given, but would add these are referred to as coralloid roots, and are common on Sago palm, image below https://commons.wikimedia.org/wiki/File:Cycas_revoluta_coralloid_roots.JPG

Far better to mulch the area or otherwise remove it from mowing. A huge tree is a huge issue when it's in trouble, and cutting roots is very likely to cause trouble, as the tree depends on the supplies from those roots, their physical support, etc.

Generally speaking, plants do not use their stems to breathe but there are always exceptions (like cacti). The rule is that plants respire through their stomata, which are (typically) located on the undersides of leaves. edit/note: A qualification should be made regarding my overly generalistic statement above. There are lenticels on stems which means that ...

Roots show positive gravitropism meaning that they grow towards the direction of gravitational pull. Vigorous plants like trees need to anchor themselves in compact soil, while small and delicate annual flowers prefer lighter soil. When tilling, the capillarity of the soil is interrupted and this means that water will evaporate more slowly. If the soil is ...

This is definitively a Yucca elephantipes. Not Dracaena. It is indeed an air root coming out of it. However, this plant is one of the easiest to propagate, you can just cut of the top of the stem or your rooted shoot and put it in the ground. No hormones or sterile soil needed. Also without these air roots it will work out fine, just make the soil not too ...

Tree pruning will not necessarily slow root growth. The best way to deal with the possibility of roots getting into things they shouldn't is to Dig a trench about six to eight inches deep between you and your neighbours at a convenient location. Then go to your hardware store and buy some 40 or 60 millimeter pool liner. Usually food grade for ornamental ...

If they are all dried out then they are dead. Avocado pits need to be planted pretty quickly after being removed from their fruit. On your first success, how did you start the pit? The method I've had the most luck with was suspending the fresh and thoroughly washed pit over a glass of water using toothpicks stuck into the seed in several spots, with ...

The right way to stake a tree is to use two or three stakes, spaced equally around the tree, and outside of the tree's root system. If you have just one stake, the tree can freely move toward the stake, or it can swing from side to side like a pendulum at the end of the support line. With two stakes at opposite sides, you only allow as much motion to or away ...

Bulbs Bulbs are plant storage organs generally grown underground, consisting of a short stem (the basal plate), from which grow overlapping, swollen leaves or leaf bases. The top growth emerges from the bulb center. Here's an example: Corms Corms are not made up of leaves, but a vertical swollen compact stem, and as such are solid. The corm is protected ...

I would also suggest that you only water the plants in the morning when the excess water will evaporate in the sunlight. I made this mistake several times with midnight watering which caused my salvia, Rosemary and lemon verbena to drown first then get fungal disease.

Tree roots stop growing immediately after the tree has been felled, but may take weeks to months (and longer) to die unless the stump has been poisoned with a herbicide. If the stump is not treated, then the roots may send up sprouts, and the roots will start to grow again. While they are alive, trying to advance their decomposition will not work. It is ...

It depends. I'm currently grown some philodendron vines in water for propagation purposes. They will stay in water for a long time with no ill effect. However, I believe that all the plants growing is coming from it's own energy stores. Eventually those will run out. You'll need to replace those. Whether that's in dirt or water is up to you. I'm sure you ...

This is a vigorous tropical climber. It can be propagated in numerous ways: cuttings rooted in water cuttings rooted in a medium like vermiculite or perlite layering where you root part of the stem in another pot As long as you have a node on the stem this plant is not fussy, almost anything goes! The one method of propagation that is unlikely when ...

I'm sorry I don't know the cause of your damage, but I have a lot of experience with sedums, and can reassure you that a healthy plant can grow even if the top is damaged, dead, or broken off; and even if the roots have come out of the soil and completely dried up. I live in Massachusetts, growing zone 6, (-10°F, -23°C) and have a number of varieties of ...

Any moist material placed against the stem of a plant can cause stem rot which is why you are not supposed to put material against a transplant higher then the original soil interface with tomatoes being a well-known exception. I am guessing you're using coir, and it's remaining moist and lying against the stem. I use hydroton in my flood and drain system, ...

I don't know that I'd consider it dangerous to plant the tree that close, but from a design perspective I wouldn't do it with any large tree - the tree will eventually dwarf the house and the effect will not be pleasing to the eye. Seeing that the tree is also a pine, I'm assuming that as the tree grows it will become wide enough to probably interfere with ...

Continuous growth, yes, it does signify root growth. The exception to this would be when moisture stored in the trunk and branches is expended to push out the foliage, but then not replaced by the roots for some reason, in which case the green growth will cease, dry up as the soft leaves lose moisture and the tree/shrub desiccates. Roots grow by continuously ...

Willows are noted for fast growth, brittle branches, vigorous root systems and being attacked by many diseases and insects. They will grow new branches from old wood and their roots will seek water where ever they can grow. You cannot change these characteristics but managing them brings it's own issues. You can get it removed and consider replanting with ...

All you can do is keep it well watered and keep your fingers crossed. Cutting off a major root from a living tree is always a risk, and only time will tell whether the tree will recover or die, I'm afraid.

Not sure you mean by this: Was wondering if you could put non-water plants onto a fish tank so that their roots grow inside the fish tank. What are the chances of the plants being dangerous to the fish? I also wasn't really sure you meant by "non-water". All plants require some amount of water. Aquaponics As for your other question: I read that the ...

If you cut the roots you are increasing the danger that the tree will pose a safety issue. roots act as a mechanical support for the tree roots provide nutrients and air to a tree. Research has shown that roots are intricately linked to specific branches. If you cut the roots then branches on that side of the tree are likely to die. The best solution is ...

Wild cherry trees like the pin cherry and the bird cherry have quite surprising root systems. The roots can extend out way past the drip line in search of water and nutrients. Your foundation is not in danger from the cherry tree. I answered a similar question here. However a fruiting cherry tree can get quite large depending on the root stock. I would ...
