Best time to fertilize in Denver?

When is the best time to fertilize in the Denver Colorado area? Also;

I have dandilions growing on the edges of my lawn, like next to the fence and next to the sidewalk. What is the best way to handle this?

lawn fertilization:  now is good. June is not good. 

Dandelions along the edges:  Are you mowing these dandelions?  Have you been following the advice from the article?

Yeah, I've been mowing them and weedeating them with my string trimmer since they are on the edges and along the fence. They have learned to grow real low and flat so the mower doesn't get very many of them so I try to get them with the trimmer. Is it better to trim them down even if it means trimming the lawn down low on the edges or to leave the lawn long on the edges even if I'm missing the dandilions? Is it important to cut them before they turn to seed or just to keep them from growing up? Also how often should I mow the dandilions? More than once a week?

Thanks,

Gary

PS. What do you think of this fertilizer?: http://www.alphaoneinc.com/alphaone.htm

For the really out of control dandies, I use a forked screwdriver looking weeder.  It works great, gets the majority of the root, it's fast, and more material for the compost pile. 

Keep mowing high. 

I would wait them out.  But I am super patient. 

You could try the vinegar trick - I've never tried it.

Hmmmm .... I wonder what a soil test would say.  It might give you some info where something easy might give your grass a bit more edge.

As for alfalfa based fertilizers.  I'm generally in favor although I am concerned about how it might burn the grass.  I like the ringer stuff because it is a very slow release product.  Alfalfa stuff also tends to repel water in a weird way. 

But if you get it for free, then that trumps the ringer stuff.

I've been battling these d'lions for several years. My lawn is 10 years old. I don't have hardly any in the middle of my lawn, only on the edges. I've been following your advice since 2006 or so and have never used chemical fertilizer on this lawn, out of concerns for my dogs. I have been using chicken manure based fertilizer. I have used Ringer before as well. I have always mulched when I mow except I was mowing lower (about 2 1/2 inches) until I read your article.
I think I will get a soil test to see what the ph is at edges. Maybe my trimming the edges too low is part of the problem.

I can't get the Alfa One fertizer for free but it is getting alot of press lately here, saying it's specially formulated for Colorado. The same place that sells Ringer also sells it so I was wondering if it was good. The bag says it doesn't burn. I will probably go with the Ringer this year instead of the Richlawn Pro-Rich chicken manure based fert I've been using the last couple of years.

Thanks

When it comes to weeds in lawns, cutting low leads to weeds. 

Attach  a pic and maybe I'll better understand the situation. (when posting, look under "additional options")

Tada!

Too bad we don't have before and after pictures for those that have a hard time believing.
