We've been picking tomatoes for the past two weeks or so and whilst the
quantity of fruit per truss is normal, the size of individual toms is
very small this year.......about 60% on a truss are the size of cherry
types such as Gardeners Delight !

We've never had this problem before. The compost mix, watering, feeding,
greenhouse ventilation and variety (Shirley and Gourmet) etc are all as
previous years, but the toms are just small !
Even my single plant of Beefsteak type has undersize fruit.

No signs of disease or pests. Peppers and chillies using the same
compost are great.

As most of the toms are ripe or colouring nicely its probably too late
to do anything about increasing the size this year but I wonder if
anyone has suggestions to prevent this happening in future.

Plants are in 3gall buckets on the greenhouse floor.

Best Regards...pp
