The different grass type is a coarser fescue, there is no specific
control
for it. Most lawns have some degree of it. Other than spraying a non-
selective herbicide on it and then seeding it, there is no product to
use on
it. The lawn looks pretty good for this time of year overall, It should
not
spread if we keep the other grasses healthy around it. Not usually
considered a problem. |

What is Roundup?
Roundup has been aggressively marketed to homeowners, gardeners, landscapers
and farmers since its unfortunate invention in 1976. It is a highly toxic
herbicide, detrimental to the environment, plant life, animal life and the
human species. Non-Monsanto-conducted studies have shown us that Roundup
causes the following serious harms:
Liver damage

Roundup: Label - Keep out of reach of children, harmful if swallowed, avoid
contact with eyes or prolonged contact with skin. Remove clothing if
contaminated.
The Women’s Cancer Resource Center (WCRC) and CHOSE (Coalition for a
Healthy Oakland School Environment), showed that chemicals such as Round-Up

kidney and liver, and some studies show a link between the chemical and

Digging ground could kill a lot of roots. And then regrading might bury the
root deeper (oh, yeah, all roots need air.) And run-off from lawn is
definitely a killer - it's not just excessive water, the fertilizer/
herbicide also matters. If you have some precious trees or a herb garden,
you gotta regrade to direct run-off away. Raised bed also works. |

发帖数: 13081 | 10 You are correct about the futility of sifting through your soil to
physically remove all the nutlets. Although most are found in the top 6
inches of soil, some may be lurking as many as 14 inches deep. You will
never collect them all. The herbicide you tried didn’t work because, after
one sprout died, a second one grew from the mother nutlet to replace it.
Individual nutlets can resprout three times — maybe more — so an effective
control strategy is to do everything you can to encourage the colo... 阅读全帖 |

Protect your water supply by carefully managing activities near the water

contaminants away from sinkholes and the well itself. Keep hazardous
chemicals out of septic systems.

mowing high, and watering as infrequently as grass allows and as deeply as
soil allows.
Personally, I think weed & feed products for post-emergent weed control is a
great marketing gimmick for the unassuming consumers. It is banned in
Canada for a reason. Why? Broadleaf herbicides are best when applied to
the leaves, so imagine how effective could a granular form be. It could

发帖数: 837 | 16 If there is one word to remember about Roundup, it should be "nuke", because
it kills both weeds as well as good grass (it is a so called non-selective
herbicide). So depending on your situation, it could be very effective, or
a disaster if you are not careful. One option is to touch paint the weeds
instead of blindly spraying so it won't affect other vegetation.

发帖数: 804 | 21 如果你不介意用杀杂草的药，你可以等到你的新草强壮一点以后再用杀杂草的药（例如
Bayer Advanced的"All-in-One" weed killer,属于post-emergence herbicide，可以
来年春天的时候洒)。不少杂草是单年生的，所以过冬会死掉，但是种子留在了你的草
坪上，所以来年春天的时候（3月）等杂草种子发芽以前，可以用pre-emergent的药(例
如scott的crabgrass preventer)来抑制杂草的种子发芽。
如果杂草不多可以手动用weeder拔除，这样比较环保又可以锻炼身体。另外有些杂草其
实对草坪没有害处，另外一些杂草往往是一种土壤缺乏必要元素的标志（例如clover多

foxtails, goosegrass, 之类的都很有效。Green Light Portrait 这个可以防止宽叶
类类的broadleaf weeds，譬如dandelion, clover, chickweed, henbit, etc.
post-emergence herbicide一般在5-6月使用，当中Bayer Advanced "All-in-One"

有机肥料当中milorganite是最容易买到和最受推崇的，但是不便宜（相对于氮肥的含

- 耐热耐旱草种：Bermudagrass, centipedegrass, St. Augustine and

加了NIS后，药不容易被大雨洗掉。施用之时切记要让药混合均匀。

这个我倒是不确定，去查了下，可以确定pre-emergent会对小嫩草也造成伤害，但
seeding后多久可以撒，说法不一：
有说几周
“If you intend to seed a lawn, you CAN NOT use a pre-emergent before you
plant nor can one be applied for several weeks thereafter.”
有的更严格，要3-4个月
“A standard pre-emergent herbicide should not be applied until at least
three to four months after seeding the area.”
当然他们没有提到秋天overseeding后草在冬天是休眠不怎么长的，不知道这段时间是
否可以算。但一般来说pre-m都是在开春撒，overseeding也是秋天做得比较多，所以有
理由相信，开春撒pre-emergent不会对去年秋天才长的嫩草造成明显伤害。除非，你
