David,
You might find more of what you are looking for at your Farmers CO-OP. The liquid iron plus is very good and it has several micros as well. This can be a good time to stock up on plant nutrients as they tend to lower their inventory in the fall.

The Iron Plus is rated 3-8-4 and the container that I have has a hose end sprayer on it that I use to soak the leaves till it is dripping.

One thing to remember is do not store the fertilizer where it will freeze, because the chemicals will salt out and the only way that I found to re-dissolve the solidified fertilizer is to mix it with plenty of hot water.

So, you guys dont think its too late to fert? I dont want to harm next springs growth, but, i dont want them to be under nourished.... What do you think i should do?

so what your saying bambooweb, is to foilier feed them through the leaves? Not the roots? or both?

Thanks a bunch guys, i really appreciate it...

I have been testing fertilizing late in the year for the last three years.
I have a number of bamboos where I purchased two of the same species and I have them planted near each other.
For each pair of plants I mix a gallon of 20-20-20 Miracle Grow mixed full strength and pour it on one of the two plants. I normally put it on the plants in late September or early October.

The only hardiness difference that I found so far is the first year the Rubro that I fertilized had stiffer culms so when it snowed the culms on the unfertilized plant were bent to the ground and protected by the snow. The leaves and culms on the fertilized plant that were above the snow were damaged by the cold weather. Since then I have not had enough snow to cover a plant during the coldest part of winter so there has been equal damage between fertilized and unfertilized plants.

One thing that I noticed this year is the culms on the fertilized plants are a little larger than the unfertilized plants So I will keep testing and see what it does next year.

Note that on the majority of my plants in the spring I add some ammonium sulphate to help break down the winter straw mulch and about 4 inches of compost. The Decora also gets some sulphur every other year and Iron Plus in late summer.

Ok guys, heres what i found.

I purchased some "Ironite Plus" brand, its 6-2-1. 1% Iron, Chelated..... Gonna give them a bath tomorrow Thanks for everyones help. Hopefully they will green up b4 winter. They have me worried going into winter looking like this....

Other than their current color, they seem happy with their new homes. They all put up 2+ culms each after planting... Only time will tell come spring again

If you are not in a hurry to acidfy your soil, you can just put some organic mulch on it like tree bark or grass clippings now, before winter. By late spring the ph should drop by a point or so.
