The watering plan has been to thoroughly soak the compost every few days and water normally in between. Of course we haven't had many hot spells where it becomes difficult to keep the compost moist, but nevertheless, I have had only a few cases of BER and I'm growing over seventy plants.
Two further points to make are, it took longer than usual for flowers to set therefore the plants are producing toms in warmer conditions (helps reduce BER caused by low temperatures) and also, the new compost and sterilisation of containers etc. this season means that there are no soil based diseases that hinder the uptake of nutrients and especially calcium.
Blossom end rot was a real problem for me last season but hopefully, I think I've got the better of it!
The three most important ways to avoid BER are:
- Water thoroughly every few days.
- Always use new compost to avoid disease.
- Sow medium and large varieties (the most affected by BER) a little later in the season for fruiting at warmer temperatures.
