Thuja Green Giants: Dead or Alive?

We planted a row of Thuja Green Giants from fastgrowingtrees.com last year. We watered them a few times in the winter, but man do they look dead. Some of them will drop "leaves" when touched. We were told that it would turn golden brown in the winter, and not to worry, but this can't be right. We've been watering more heavily the last few weeks, but it is not looking good. Are these dead? What went wrong?

replanting a rose bush

Hi, My friend has a hybrid rose which she has had for a lot of years (now I can't remember the name -
starts with a "P"), and she hasn't seen any in the Ft. Collins area for a long time. It seems to have two
crowns with the upper crown about 4 inches above ground. We had the intention of replanting it deeper
in the same hole, but in digging down a good foot, the main root keeps going down and refuses to come up. We built up soil around it to cover that crown. If we break that main root, will it kill the plant. Or is there a point that we can break the root safely? Should we have the soil built up or leave that second crown exposed. (It was covered all winter.). The rose didn't do very well last year. Thank you for your help and
time. Ellen Wride

Pollinators in my lawn

When is the soonest time of year to mow to protect larval and adult pollinators living in lawn grass and leaf piles in Greeley? Is there a preferred time of day with regard to this?

shrub recommendations

I am looking for a full, dense shrub that is 4-5' high max for a space that gets morning sun until about 2pm. I live in Denver. Flowering would be ideal, but no fruit as I have a dog in the backyard. The shrubs will be used to hide the air conditioner/storage area in the back yard.

Thank you!

Why haven't we put kochia and Russian thistle on the noxious weed list?

Russian thistle and kochia weeds are wrecking havoc throughout the eastern portion of our state. Why are we acquiescing to the farmers who allow four foot high weeds to grow on their summer fallow, break off and blow across the fields and pastures disturbing top soil and contributing to the erosion of top soil as they spread their seeds for another crop of the same. The big lie in agriculture is that we can't tell farmers how to farm. No, perhaps, but according to CRS 35-5, we can require them to control their weeds.

Weed killer

We put preen extended control on the soil in our vegetable garden then realized it’s not advised. Do we need to replace the soil or can we neutralize it?

ADA ramp

We live in Pueblo West Colorado. When a person came out to measure the distance from the threshold of our door to grade level, he mismeasured the threshold to grade elevation. He measured 18 inches instead of the correct 26 inches. Because of not wanting to admit his mistake, he did the following. He terminated an 18-foot ramp, 12.5 inches above grade level. Is there any information that states in a residential installation that the purpose of the ramp is for a handy caped person to exit the home and progress down the ramp and land at grade level. We just had a ramp installed by Thornton Medial and it goes from our door threshold to a concrete slab, the top of which terminates approximately 18 feet away and 12.5 inches above finished grade. There is no access from the top of that concrete pad to grade. They are telling us that the finished slab does not have to terminate at grade level. I asked the question, so, my wife, who is handicapped, can leave our home, travel down a ramp to a concrete slab that is 12.5 inches above grade, and that is as far as she can travel? They said yes, they had no obligation to terminate the end of the ramp at grade level. They told us that we could pull a vehicle up to the concrete slab and my wife could simply step off the slab, and into our vehicle. The question I have is, what is the purpose of an ADA ramp if it does not take the handicapped person from their home to grade level? Thank you very much, Bob Mondey, Pueblo West, CO.

Should I build a hoop house?

Hey! I'm considering building a hoop house in my backyard for fruits and vegetables. I'm wondering if a hoop house is going overboard or if it will really help my vegetables do better. My yard faces south and gets tons of sun.

Bird feeder

Is there a bird feeder and a hummingbird feeder that does not allow seed or liquid to drop on the ground. We have an issue with raccoons, squirrels and rats in our area and don’t want to feed these animals
