Yes, salt will kill plants. In theory, if you use enough of it in the soil, it will kill a tree. Regarding whether its permanent, no, its not. If you saturate open ground with salt, everything dies, and, by and large, nothing grows for some months, even years. In your case, you want to know whether it works permanently when its been applied to paving. No, ...

Mint does not care for being mowed. If you just assert your ownership of that bit of the lawn, and mow and weed whack as you prefer, eventually it will be less minty. Oregano, in contrast, seems to decide to become a creeping ground cover in the face of endless mowing, which isn't entirely a bad thing. We have fragrant walking paths. Sure, while there are ...

Personally, I hate weed whackers. They're terrible at my house: the places I need to weed are either next to plants that can't get whacked, or they're next to wire fencing that chews through tons of string, or they're next to rocks that chew through tons of string. My preferred tool for getting in next to the fences, lilies, and trees is a pair of manual ...

It's Euphorbia maculata (or a closely related species), commonly known as Prostrate Spurge or Spotted Spurge. More images from Google here. It forms a tap root, so it's fairly easy to control by hand; my technique is to find all the branches radiating from one central stem, them grasp the stem just below the branching point and pull straight up. I've also ...

I have been using salt to control my neighbor's bamboo for 5 years now. He planted a 200 foot line of bamboo with no intention of controlling it. I had to trench my own yard for 200+ feet and lay in a barrier 3 feet off the property line. (After I removed over 100 feet of roots destroying my yard). Then to keep the plants from filling in from the barrier ...

You need to keep your grass healthy to help combat ground ivy. Water deeply and infrequently and fertilize properly. Have a soil test done at your local cooperative extension to see if there are any issues you need to correct and how much fertilizer you need to add. Ground ivy thrives in damp and insufficiently fertilized soils. There have been university ...

Glyphosate needs to be applied while the plants is actively growing and transpiring moisture, which requires sunlight. This means you need to apply glyphosate in the morning so that it will take effect during that day. Glyphosate it deactivated very easily so applying at night, even if it doesn't rain, is likely to be ineffective. So, apply in the morning ...

Your best bet is probably to pour boiling water on the weeds. The heat will kill the plants, and the water will of course be harmless to the birds as soon as it cools. Just be careful not to burn yourself!

Something not suggested: sheet mulching for "lasagna" gardening. A local department store will probably give you 4,500 sqft of cardboard boxes for free -- they may even deliver them! De-tape and de-staple them, break them down, and put them over everything you want to kill. Put a bit of topsoil on the cardboard to hold it down. The cardboard will eventually ...

It's thistles. You're probably doing the right thing - just keep at it. This time of year, weeds can seem unbeatable. The main thing is to loosen the soil out about a foot from a big thistle, with a gardening fork or similar. Then try to get all the roots in one go with a spade, or by pulling. With little ones that regrew from little roots you missed, ...

Oh boy! I made the same mistake and now mine occupies about 3-4 times the area in the pic on the right here (that was taken last Oct). It's hard to tell if you're really done pulling it out, because the stolons could have propagated quite far. I don't know of an easy way (I doubt there's one...). The approach I'm taking now is to mercilessly cull most of ...

We own a tool that looks just like the one on the right here: I used it just last week - it's good for goldenrod, raspberries, oregano and the like. After a round with this the mower can handle it. Instructions for using it are at the American Trails site, among other places. We own a gas powered trimmer, but this is actually quicker (and lighter and ...

Ooh, dear, sorry AvieRose, that's because there isn't a once and for all solution. Bindweed is practically impossible to eradicate, as you've discovered, so all you can hope for is to keep it in check. In light soils, it's often possible to extract the bulk of any root material when the area is unplanted, but in clay or heavy soils, it's much harder because, ...

I'm pretty sure this is Cow Parsley (Anthriscus sylvestris), an invasive but non-toxic weed, not Giant Hogweed (Heracleum mantegazzianum). Differences between the two include: Leaf structure: Cow Parsley's leaves are fernlike, Giant Hogweed's leaves are much larger and coarser: Cow parsley leaves Giant Hogweed leaves: Height: Cow Parsley grows to about ...

With those long underground rhizomes (the thick white runners you see) and upright growth this appears to be quackgrass (Elymus repens). Unfortunately, controlling it isn't much easier with that bit of knowledge. Quackgrass is a tough competitor. There are no selective herbicides that can kill it without killing the lawn grass, and as you've discovered ...

I think almost anyplace is better for weeds than a dumpster, for the reasons you list and more. But there are concerns, too. A hot compost will kill weed seeds. Get a compost thermometer, and make sure your hot pile is fairly big so it can get hot in the middle -- we use shipping pallets, which makes for a roughly 3' cube. Do you have chickens? Know anyone ...

The clover (assuming white clover) is spreading on its own because, most likely, the soil is low on nitrogen, which favors the clover instead of the grass. Clover can fix nitrogen from the air, so it thrives in the low-N soil where other things have a hard time competing with it. According to this: Do legumes provide nitrogen to their companions? Clover ...

Vinegar acts as a desiccant. It dissolves the protective coating on the leaves of the plant causing it to dry out and die if the temperatures are warm enough. It usually doesn't destroy the roots and sometimes the plant may come back if there is enough energy in the root system. Dandelions have a large taproot which makes them difficult to kill with ...

Your strawberry and veggie patches are almost done for the year where you live, so it seems to me it would be best to tackle them next spring. For now, I would cut down the weeds as close to the ground as possible, but not worry about getting rid of them altogether. In the spring, when the strawberries (and weeds) start coming back, you'll be able to hand ...

I'm in the UK, and we don't have poison ivy, oak nor sumach, so I've never actually seen them. However, the small leaved plant covering the ground in between the Hosta leaves and the one with palmate leaves appears to be Vinca minor, common name lesser periwinkle, usually has blue flowers in spring. The palmate leaved plant looks like Parthenocissus, or ...

Some years ago I apparently eradicated bindweed from a small (15 x 7 feet) unenclosed front garden adjacent to the parking lot. I lived on an Estate where a number of small, bored children were always looking for something to do - so I offered a small bounty to the child who dug out the most convolvulus roots. The game was played every Sunday and roots had ...

They look like small Asparagus spears. The triangular leaves (like scales) on the stem and the slightly swollen tips of the stems are the characteristics that helped that identification. An image search for "Asparagus+spears" will provide lots of other photos for comparison. Wikipedia says that they're native to your region (Iran), and that it even gets ...

One should always address the soil before tackling weed and plant issues. I'm a firm believer that good soil = healthy plants = few diseases and little need for chemicals. Every plant has a place in which it likes to grow, due to soil composition and climate. Once we understand and accept this principle, its a matter of deciding how to modify conditions ...

Composting Pros: germicide. Cons: it take times, some clover seeds can germinate after composting and it is not suitable for large gardens. Herbicides (Postemergent) Pros: As per @J. Musser 's suggestion > quick; especially on rocky and hard soil. Cons: all derivated from herbicide use and clovers may regrow. Herbicides (Preemergent ) Pros: quick method ...

You must not use Scotts Weed and Feed formulation now for two reasons - one, you've already applied a weedkiller to the entire lawn, and one of the active ingredients, 2,4D, is present in both formulations, which means you'll be overdosing on the weedkiller front. Second, where you live, your first frost date is early October, so feed should not be applied ...

The active ingredient of the herbicide used is Dicamba Mecoprop. It also affects broad leaf shrubs and trees. From this pdf by the International Society of Arborists Once the material is absorbed there is no treatment to alleviate the symptoms except to avoid watering and fertilization. Removal of the tree should wait the second year because often a ...

Read the label of the product you are using. The label will state a re-entry interval. Without the label we don't know what is in the specific spray you are using, so we can't give a proper answer.
