Re Epsom salts. I've come to use this as a tonic on many plants. Tomatoes, lupins can become chlorotic slightly in parts of my soil so Epsom salts is ideal for them, azaleas, etc in pots, camelias, hellebores cos I feel it helps, fruit bushes sometimes, etc.
the concentration is not crucial ......a teaspoon in a litre spray or tablespoon in 10 litres watering can.
