Hi,
I am in Albuquerque, new mexico. I have some questions about lawn
care, especially weed control.

I asked a landscaping company installed my backyard lawn this
January. It was good until about 1-2 month ago: it seems all out of a
sudden lots lots of dandelions coming up over a night! Before that
there was few weeds.

My wife suspected that's because usually I mowed front yard just
before back yard and our front yard always has dandelion.

Now my question is how to control it.

I went to Home Depot, the guy there told me to buy Scotts Plus 2
Weed Control, I did that, but it worked not very good.
Then I went to Rowlands, a famous nursery store here, the guy told
me to buy some product branded Fertilome, again it worked some, but
some so good.

I checked web and book store, someone claims that no easy way at all
to terminate dandelion. The only effective way is to pull them out by
hand!

Because we are disappointed by the products, so we did it today, --
pull them by hand.

It is so much work! We did most, but not all. the reasons are some
broken roots are still there, some are so small that it is hard to
pull them from the good grass, and last, we are too tired to complete.

The question:
1) In pulling the dandelions, we digged many holes. How should we
do with them? Put some dirt, compost or it's fine to do nothing?

2) How to do with the small ones, wait until they grow?

3) In general what's your experience of southwest lawn care?
Someone does not like commercial programs such as Scotts program, how
do you think?

Thanks.
