    A tablespoon to a watering can is my way about once a month. It also goes on the tomato's at the same rate once the fruits are set plus of course the usual tomato fertiliser and a top up of fresh compost or potting soil.

    Also if early in the season the tomatoes show yellowing of the foliage give them dose of the old Epsom Salts . A teaspoonful in the watering can, one dose all that is necessary.

  • Thanks to everyone, Epsom salts applied will wait the outcome

  • Are epsom salts good around all the garden or more specifically for fruiting shrubs and trees? 

    I have 3 container growing young honeysuckles with yellow leaves and thet think its autumn-they are drooping and dropping off. Y garden is all slabbed and a sun trap. Im a true novice andcwould welcome any advice. I have asked for advice here because I know mature honeysuckles can have berries. Thankyou.

    Kaye, honeysuckle is a woodland plant so shade the pot and water it frequently, they like moist and cool roots. if you can do that it should recover.

    Epsom Salts is "Magnesium Sulphate" , magnesium being a key element in plant growth and can be deficient in some composts bought in stores.

    Magnesium (Mg) deficiency is a detrimental plant disorder that occurs most often in strongly acidic, light, sandy soils, where magnesium can be easily leached away. Magnesium is an essential macronutrient found from 0.2-0.4% dry matter and is necessary for normal plant growth.

      A plant with Magnesium deficiency

    Excess potassium, generally due to fertilizers, further aggravates the stress from the magnesium deficiency, as does aluminium toxicity.

    Magnesium has an important role in photosynthesis because it forms the central atom of chlorophyll. Therefore, without sufficient amounts of magnesium, plants begin to degrade the chlorophyll in the old leaves. This causes the main symptom of magnesium deficiency, chlorosis, or yellowing between leaf veins, which stay green, giving the leaves a marbled appearance. Due to magnesium’s mobile nature, the plant will first break down chlorophyll in older leaves and transport the Mg to younger leaves which have greater photosynthetic needs. Therefore, the first sign of magnesium deficiency is the chlorosis of old leaves which progresses to the young leaves as the deficiency continues

    I've had yellowing of the leaves on one of my Daphne. On the advice from this forum I watered the plant with epsom salt with great results. I've also sprinkled some epsom salts around the plant.
