除草剂好，让我自己研究。我是应该买：
1.Roundup还是

另外，带weed killer的fertilizer是不是weed killer的浓度大小和种类也有讲究？
请大家推荐一下。谢谢！ |

Right, round up once probably isn't enough. When people do lawn renovation,
they round up once, then water for a few days to a week, and round up once
again. Sometimes people do it a third time. Still, this won't guarantee
there won't be weeds in the new lawn, just much fewer.
If you don't like roundup, you can try organic solutions like vinegar (15-20
%, dangerous though), baking soda (spray powder form after spraying some
soapy water), or boi... 阅读全帖 |

发帖数: 837 | 6 The answer to your question is a definite no.
Roughly speaking, weeds could be grassy or broadleaf, summer annual or
winter annual or perennial (let's just ignore biennials for simplicity
purpose). So there is 6 combinations.
Winter annuals generally germinate in the fall, green through the winter,
set seeds in the spring and die in the summer. A recent post showed
pictures of bittercress and shepherd's purse, which are both broadleaf
winter annuals:

WBG works slowly into the root, so check back in 2 week. However, it is
effective to broadleaf weeds, but not that much to grassy weeds, so you need
to know what your weeds are.
Moss killers most likely have ferrous/iron sulfate as the active ingredient.
Ferrous/iron sulfate is also used medically to treat iron deficiency, so
it isn't in the same category as the toxic herbicides like 2,4-D, triclopyr

Weed your space constantly
. If your space is set up for activities you used to do, remove the furniture,
supplies, and equipment left over from those activities if you're no longer
using them.
. Pay attention to the corners and flat surfaces in each room. Piles tend to
collect in these spots first. Every time you see a pile developing, go through
it and weed it out.
. Every time you finish working on something or playing with something, put it
