2024 - What I did today

I pruned some more tomato leaves where they were shading trusses and took some cucumber leaves off too, did some watering in the gh and harvested. Only had a couple of hours in the garden but achieved something at least.

Tomatoes don't need sun to ripen, if that's the reason you're taking leaves off.

A bit of both, unshading a few and giving the plants a bit more air around the lower areas , taking of some browning leaves and giving me some room to walk in the gh.  Nothing too drastic. If they don't need sun, why are we told by pundits to unshate trusses, I wonder?

Pundits are often wrong and tend to parrot what they already know. There's a lot of old wive's tales and incorrect gardening advice out there, adding crocks for drainage at the bottom of pots is a very common one. I think if they consulted horticulturalists, scientists or professional growers, they wouldn't come out with so much guff. In very warm parts of the USA, growers prefer to keep leaves on as much as they can because they shade the fruit and prevent sunscald.
