How often can you use Weed'n'Feed
How often can I apply Weed'n'Feed.
If you are using the Weed n Feed Granular fertiliser, this fertiliser can be applied every 6 weeks during the growing season on an established lawn. If you are using the Weed n Feed liquid hose-on, this product can be applied in early spring and then again in autumn.
