You can use different lawn fertilizers for spring, summer and autumn, or use
the same type all three seasons. I use just one type all seasons except
winter. I don't use feed 'n weed because it will kill my flowers and
vegetables.
For all liquid fertilizers, you need to read the instructions carefully.
Some are ready-to-use. Some must be diluted before use.

这部分没看懂. 20-20-20, 30-10-10, 6-30-30,are those all fertilizer types
? could you please give me to link of the actual product? thanks.
==============
Fertilizer:
Warm weather (20-20-20 or 30-10-10) 3~4 times a month, 蝴蝶兰喜肥,这时候
多氮气肥,我都是用得 20-20-20
开花期(9~3月), 用 6-30-30 ;多磷肥,促进开花。我用得是19-31-17, HD 买的
。once every two months.
* How to boost bloom:
Decrease evening temprature to 56F. 我平时都放在室外。降温要拿进来。不能太阳
直射会灼伤叶子。半阴半阳最好。

不少同学在后院开块小地,种点时兴蔬菜,即益胃,又解馋,还可拿到网上炫耀显摆。
啊,庭院种菜真是人生一大快事!
庄稼像朵花,全靠肥当家。要蔬菜长得好,肥料是关键之一。以前国内宣传过这么一个
英雄人物,这个大英雄在危难之际,面对前来救援的同志们大声喊道:不要管我,抢救

我家苗圃因为面积不大
都是用Kellogg Amend Garden Soil
土里面已经混上了鸡粪什么的有机肥,所以略带臭味
肥力还是很足的,菜长得很好
平时用Kellogg Natural&Organic Fertilizer for Tomato&Veg追肥
也是黑不拉几的东西
既然人说了Organic Fertilizer,我也就暂且信了
好处是省的动脑子去琢磨怎么配土和肥

化肥含有植物所需的矿质养分,如氮磷钾钙铁硫等。化肥施到土壤以后。这些矿质养分
溶于土壤水中,再与从有机物(如土壤中的腐殖质)分解后的矿质养分混在一起,以离
子的形态被植物吸收。植物再将这些矿物质、二氧化碳和水份转化成有机物质(如各种
蔬菜),供大家食用。
化肥和有机肥相比,既有优点,也有缺点。化肥最大的优点就是比有机肥,特别是动物
粪便,来得卫生、清洁,不含致病微生物,不含抗生素和激素。化肥的另一个优点是养
分高度浓缩,施用起来比较省事。当然,化肥的缺点也不少,这些缺点应该引起大家足
够的注意。在这篇短文中,我就和同学们谈谈在庭院小菜地施用化肥要注意的几个问题。
一。注意不能只施用化肥,一定要往菜地里补充有机质。
有机质含量高的土壤,通常是肥力高的土壤。土壤中有机质在分解后可以为植物提供平
衡的养分,还能改善土壤结构,使土壤里的矿物质更容易被植物吸收。虽然现代农业已
经可以用无土栽培的方法,只需要化肥和水就可以种出卫生、健康、美味的蔬菜。但如
果在土壤里种菜,还真没有办法替代土壤中的有机质。所以提醒庭院种菜的业余农民,
一定要及时地、尽量多的往土壤里补充有机质,不能只施用化肥。

来自主题: gardening版 - 反驳“吃新鲜蔬菜就是吃化肥”
这位杨兄,你听我说!
1. “ 您用饮用水的NO3标准来衡量蔬菜中的含量”。
我不是这个意思。我举饮用水的例子是想让大家有个概念,我的原话是“很多同学对这
个浓度可能没有概念,那我就举两个例子,帮助同学们认识这是多高的浓度。”饮用水
就是其中的一个例子。
2. “饮用水中是10ppm NO3-N,相当于45 ppm NO3”。
这点我也提到了。我的原话是“美国环保总署(EPA)规定自来水中的NO3含量不得高于
45 ppm(相当于10 ppm 的NO3-N)。”
3. “但是在蔬菜中的标准是3000 ppm (欧盟),美国似乎还没出台”。
同意后半句,我也没有看到过美国的标准。EU对农作物规定的硝酸根含量标准是3000-
7000 ppm,不同作物和不同季节,标准不一样。
4. “当然,吃蔬菜前好好洗干净fertilizer的残留还是很必要的”。
同意,特别是organic fertilizer, e.g., manure。

下面3张照片都是十月份拍的,很大的差别。
2010年十月白菊花越长越大,一大圈。
去年十月的金黄菊花开得多好。
今年十月的金黄菊花开得稀稀拉啦的。很大原因可能是番茄抢了阳光抢了土地。

来自主题: gardening版 - 草地上冒绿芽的都是什么草?
不是那个是春肥(带crabgrass preventer)。
冬肥是winterguard.

你们应该也是冷季草了。这个俺知道。
具体施用的时间以土壤温度为准,一般当土壤温度达到50-55华氏度就开撒。没法测土
壤的另一个参照物是看Forsythia花开(跟迎春花长得一样),刚开的时候就是该撒药
的时候。略早一周也可以。实在撒晚了也不是很大问题,漏长出来的螃蟹草可以用杀草
剂对付。
具体的pre emergent有几种:

这个是肥料/preemergent二合一的。这个是固体颗粒,适合用旋转小推车撒。但怕大雨
冲刷,特大雨过后就没效果了。
2,两种液体的药。俺用的是其中一种,去年用过,效果超好。等回家俺查一下名字告

这一篇咱们说除草。这个俺以前也发过贴,这次补充了来自网络/网友的更多信息,供
大家参考。
这里的方法主要适合北方冷季草里常见的Kentucky Blue Grass和大多数fescues。fine
fescue比较细嫩,用药量要酌减。
一、常见杂草种类
杂草一般粗分为寬叶草和细叶草。寬叶草顾名思义就是叶子较宽的草,常见的包括
clover, 蒲公英等,款野草用常见的post-emergent herbicide药很容易除。
clover(四叶草)

University of Agricultural Sciences in Uppsala who was not involved in the
beet study but has researched urine recycling for over 15 years. Food gives
