enriched all our lives with these worthy
thoughts:

My large block drive and patio areas ( which are not in contact with
flower beds ) have become very weedy since autumn. I intend to spray
them with a long-lasting weed-killer and would like to know
1. What inexpensive spray gun to use, and

Watering can with fine rose.

2. What long-lasting weed killer to use.


Sodium Chlorate, then treat the driveway with a top quality
urethane sealant, summat like Resiblock 22, which will keep the weeds
at bay for a good 3-5 years.

Doesn't sodium chlorate tend to leach sideways?
