Hi,The leaves on my tomatoes are turning brown & dying. The new tips are turning yellow.

The bottom fruit is ok but the top fruit has brown markings on them.Inside the stalk is clear with no sign of discolouration.soil PH is 5 1/2, it has plenty of compost added to it and mulched with lucerne chaff.I use only organic fertilizer such as dynamic lifter and fish & kelp. They are only grown in the same spot 1 year in three.They get a deep watering twice a week.Please help as this is the 2nd year that the problem has come along.

Answer: Hi Geoff,

What a shame you are having a problem with your tomatoes at this stage of their development.

Have you checked the new foliage for any insect attack such as aphids, thrips white fly and tomato russet mite. Nature’s Way Insect & Mite Killer, Natrasoap will control these insects. Have you also checked the fruit for fruit fly damage. You will notice a sting mark and then a sunken area around that sting mark. Fruit fly should be controlled at this time of year otherwise all of the fruit will be stung and not suitable for picking. Nature’s Way Fruit Fly Control contains a natural insecticide that will kill this pest.

The yellowing of the leaves usually indicates a nutrient deficiency, but you appear to be fertilising on a regular basis with Dynamic Lifter and fish emulsion and both of these products will supply the necessary nutrients your tomatoes need to thrive.

Keep your plants well watered during the hot summer months. Try to protect your plants from sunburn during this hot period.
