This Farmnote is intended for agricultural areas of WA in the 350 to 600 mm rainfall zone, and is an introduction to the topic. Site specific advice from a consultant or other professional is especially important for difficult sites such as mixed plantings where there may be doubt as to the herbicide tolerances of the plants. This Farmnote is part of a series focusing on successful revegetation techniques.
Weed control is the most important aspect of successful revegetation.
Without weed control seedlings are unlikely to survive. In a dry finish to the season, weed control will markedly improve seedling survival over summer, and in a wet year, weed control improves growth rate over summer and into the second year. There are several methods of weed control. The use of crop rotation, pasture topping, grazing manipulation, herbicides, scalping and mulching can be combined to give an integrated approach. Pre-season weed control Weed control begins a year or two before planting.
