do i need to lay plastic or weed fabric before dirt and mulch?

 

[greenman]

NO way!

My story to explain my opinion is at www.mdvaden.com

In ADVICE, then Landscape and Equipment Advice - the topic on Weed Fabrics.

Hydroponics is a good example to explain the failure for fabric success.

Apply Preen instead of fabric. It keeps seeds from germinating.

Just make sure you have that pesticide license if you are using Preen.

No, but an herbicide just the same. Thus you need to be licensed.

Same here, preen or snapshot, prior to mulching, then a good 2-3" thick layer. Tip: Cypress and many other mulches are very easlily spread with pitchforks, say goodbye to bending over all day.

In Oregon you would not have to have a license, unless it changed very recently. But on a few conditions:

1. No advertising of its use.

2. Its about 10% or less of your work.

3. You need to keep an application record.

4. No motorized application equipment.

This is actually a bigger window to apply without a license than it appears.

I would expect that many of the laws regarding licensing are different for each state. In Oregon, its handled by the Oregon Department of Agriculture.
