Seaweed concentrate

Seaweed concentrate is an excellent soil conditioner. It contains alginates and thus improves the soil structure. Use seaweed concentrate in a very dilute form, no more than a couple of tablespoons in a full watering can. Remember it is not a fertiliser but it does contain lots of trace elements. You can use this solution to water seeds which will absorb all the trace elements.

You can make a spray of seaweed concentrate plus a teaspoon of the trace elements zinc sulphate, iron chelate, magnesium nitrate and boron. Spray it on to the leaves and stems where it will be absorbed by the plant. The liquid will also drip on to the soil where it will improve the soil structure.
