Soaker hoses do more than slowly water your garden. Use a specially made gadget to fertilise plants at the same time you water. No more messy sprayers or granulated fertilisers. Liquid fertiliser mixes with water at a ratio of 1 part fertiliser to 16 parts water and distributes the product in about 3 to 5 minutes. Use this method for chemical fertilisers, or even organic liquid fertiliser like fish emulsion.
Attach the end of the siphon mixer to an outside faucet.
Attach the other end to the big end of the soaker hose.
Mix the liquid fertiliser in a container according to package directions (some siphon mixers come with a container).
Insert the rubber hose from the siphon mixer into the fertiliser. Turn on the water to begin fertilising.
Siphon mixers are sold under different names online and at garden stores. Run water through the soaker hose between fertilising treatments to prevent clogging.
Follow fertiliser directions carefully. Wear gloves and protective clothing. Over-fertilising causes plant damage and can pollute groundwater. (Reference 2)
