It’s important to keep your tomatoes continuously watered otherwise when the soil dries up, the tomato skins harden.

When the plant is watered again the tomato fruits can no longer swell properly due to the hardened skin and so the fruit splits. Fungal spores can then enter the wound and ruin the fruit.

The tomatoes ripen in sunlight so it’s a good tip to cut away some of the leaves to allow the sunlight to reach the fruit. Removing some of the leaves will allow air to circulate and reduce the risk of fungal attack.

 Remove any shoots as they will be taking nutrients away from the ripening fuits.

Mulch around the base of the plant to help reduce water loss.

It’s the end of July and the first few of my tomatoes in the greenhouse have ripened.

    Side-shoots look very much like new healthy stems. How can you tell the difference between the begining of a fruit-bearing stem and a side shot?

    Actually, infrequent watering doesn’t persay cause the cracking as seen in the first photo. The circular nature of the crack around the stem end would point more towards a combination of UV light (via not enough foliage covering the tomato) and a variety of tomato that is thin-skinned.

    Infrequent watering usually leads to blossom end rot. The ‘hardening’ of the skin is due to a deficiency of calcium — calcium uptake is regulated by water uptake. The may point of expansion growth in the tomato is in the region of the blossom end scar, so cracking occurs there.
