USDA PROCESSING PLANTS

We market out of state. Why is there no accessible list of USDA meat processing plants with cryo freeze packaging accessible to small ranchers. I can more easily haul my stock out of state. I need a list oF processors open to spall ranchers, USDA approved, which is required by my customers. Is this data that you don't have? You should be able to pull it out of the giant list you keep sending me with all the state and USDA plants mixed together. That list mentions that they are mixed. It is several pages long, sorted my plant name. I need a list of USDA plants sorted at least by county. Such a list exists for the state facilities.

giant horsetail invasion

after clearing my back yard of himalyan blackberry and wild clematis, it has been taken over by giant horsetail, touch-me-nots, and some garlic mustard (for good measure). i've dug ... snapped tops ... and even resorted to a bit of herbicide. not much to show for my efforts, except more horsetail. short of an all-out chemical attack, is there any hope? the yard is essentially a large hole, open on one end with a creek running next to it. it's a natural seepage site. the center is muck and supports a large crop of skunk cabbage. will liming the soil help (i.e. raising the pH)?

Best type of grass to grow

Our backyard needs to be reseeded for grass. I am unsure of the type that was previously grown. I run a small home daycare and put in a sand box a couple years ago. The sand has basically been dumped and spread throughout the yard so there is a thin top layer of sand. What do we need to do to get the soil back to normal and what type of grass will grow best in this circumstance? The area is 50% shaded and is on the east side of our home. We have an unusable sprinkler system that we plan to repair in the next couple weeks. We have one dog and lots of kids that run through the yard. We are unable to afford sod so we plan to seed. A friend recommended buffalo grass. Any information is appreciated. Thank you.

Help me save my tomatoes!

Hello! I have tomato plants that I grew from seeds awhile back, and are various sizes, from 6 inches to 3 feet tall now. Many have yellow blossoms, and I am really excited to have tomatoes that I grew myself thriving in my southern window!

HOWEVER, I have FLIES, and LOTS of them! I have literally spent hours reading everything available to me on the net and on your site before writing, and I am more confused than ever. I think I might have 2 different kinds of flies, since the symptoms are so diverse. Can you help me identify them all, and get rid of them in the least toxic way? Here is what I see...

1. Even when I let the plants dry out to the point of wilting, as soon as I water, little black flies that look like fruitflies fly out from and around the soil and water, as if to play & thank me. That is when I thought they were fungus gnats. (and still do), but they do not seem to diminish even when I almost kill the plant by not watering in hopes that they would die instead.

2. Now I also notice now that there are clusters of little light spots that are alive, and now hatching on leaves! YUCK! They seem to congregate together in a colony on a few leaves of choice, and when I pick off the leaf they are on, they seem too dumb to care much and do not try to get away. This made me think they are aphids, since they are cogregating and hatching on leaves and not in the soil or on the stems. ??

3. There is a white "dandruff" directly under the leaves they are on, and it is all over the plant below those leaves, on the soil, and all over the table. It does not seem to be sticky like I see described in other places. What the heck is this?

4. The last symptom is that they DO congregate on the WINDOWS when the sun comes out, and occasionally commit suicide in my morning coffee. But these files do not seem too interested in my compost bin over at the sink, so I am pretty sure they are not fruitflies, although they look like them.

SO...do I have aphids, fungus gnats, or BOTH? How do I safely and effectively get RID of them?? I read on your site that insecticidal soaps can be too harsh, but there is nothing that tells me what kind I CAN use, or what soap to make it with. How about a recipe? Several other things on the net say to mix garlic juice, cayenne pepper extract, or even a splash of rubbing alcohol with the soap as well. I am so confused! :(

When I took these puzzle pieces to Home Depot for help, they didn't seem to have much in the way of helpful info, or safe pesticides for edible plants. I was sold a pretty toxic looking bottle of junk called, "copper fungicide". I used it once awhile back, but I am afraid it will make the tomatoes poison, and I am not even sure which kind of flies I have, or if it worked. There has got to be a better way.

I plan to put these tomatoes outside in patio pots as soon as the frost danger has passed. I need to repot them ASAP now, as they are too crowded. I was going to treat them and repot them at the same time, so I need advice ASAP.

I am new at this, and need to call in the expert BIG guns...so I am turning to YOU! I am attaching pics below. Could not get shots of the adult flies that go up and down the window, but they are a nuisance as well. PLEASE HELP! Thank you SOOOO much! :)

Cheers,

Lisah Brown

I've narrowed down my front lawn grass as being a green all year round, bunch type grass planted under a live oak in 1992----what turf type tall fescue variety was popular for Dallas lawns back then? The blades are medium and the grass is soft underfoot. very nice to walk on, durable and responds very well in the spring to nitrogen. Almost an emerald green color. Sorry no pics.

Heights of lowest branches.

Oaks, maples, any such. Assume 5' tree, lowest branches 2.5' (at trunk), and that those same branches will remain forever. Do we expect lowest branches' final height to be approx 2.5' ? If significantly higher, then I need to know more. Objective is lowest branches finally at 4'; and I do not know which branches to leave on little trees in order to achieve it. I want to remove unnecessary low branches very early , because I have discovered the amazing boost to young tree growth. Conversely, I want to leave low branches that are destined to be at 4'.
