Dust Storm Clean-Up (Phoenix, Tucson: fit in, landscaping, disposing)

[mn55110]

This most recent of dust storms in the valley blew two separate tumbleweeds over the concrete block wall into our backyard; both tumbleweeds are more than five-feet tall.

Cutting them up and disposing of them is not the biggest of our worries. Each tumbleweed has dropped hundreds of seed onto the ground leaving the real possibility these weeds will take hold in the backyard.

Does anyone have any suggestions for picking them up and/or good herbisides and pesticides to kill these seeds? Which landscape or garden centers either in "The Valley" or Tuscon which carry good pesticides and are knowlegable in their use?

Thank You in advance for your suggestions!

Go to any independent garden center/nursery and ask for their on staff "Certified Nurseryman" for answers to any of your questions. Especially on herbicides and pesticides. It makes a difference in what you want to accomplish.
To prevent the tumbleweed (Russian Thistle) seeds from germinating ask for a 'pre-emergence'. That will sterilize the seeds only and prevent them from germinating. It will not effect anything that is already growing.
Tucson & Phoenix have many garden center/nursery sources, or you can contact the State Agriculture Extenion Service for your area.

What kind of landscaping do you have? If it's larger gravel or grass, try using a leaf blower with a vaccum attachment, you should be able to just suck up all the seeds.

Thank You for the suggestions received so far!

We have a gravel yard with some rock, native vegitation and a wash running diagonally across the backyard and out a small openning in our concrete block wall.

The cut-up tumbleweed fit into seven large yard bags, and were not yet finished.
