Can I apply Baticlean CR with a watering can?

Yes, Baticlean CR can be applied using a watering can. However, you will not get the high coverage that you would with a sprayer. Coverage with a sprayer will be around 30m2 per litre but a watering can will give you far less coverage than this, even with a fine rose sprinkler. So, if you have only a small area to be treated (and you don't already have a sprayer), then it is probably be easier to just use a watering can. However, investing in a sprayer if you have a larger area (maybe over 100m2) would be a very smart decision, especially if you would plan to continue to use it in the future.
