7 great gardening tips
Get the weeds
The gardeners try to use the least toxicity possible when controlling weeds. Organic herbicides (such as plant extracts plus acetic and citric acid) are tested for weed control in turf plots. For flowerbeds, the gardeners often use preemergent herbicides once the plants are established, and then they follow with mulch immediately.
