I’ve heard that while tomatoes and peppers are warm weather crops, they don’t like excessive heat and direct hot sun.
The recommendation is a sun shade for peak heat in July and August.
Yep, up in the 90s, tomato flowers can drop off and the fruit won’t ripen. I had a heritage cherry that didn’t drop flowers but wouldn’t ripen for almost two months so I counted over 200 fruits on one plant. Then it cooled off and I had way too many maters all at once.
Yep. Tomatoes don’t pollinate when over about 85F.shade cloth really helps them in the hottest part if you can get it above them.
My cherry tomatoes tend to stop producing new tomatoes for about a month in the July to August time period when it is hot even in early morning but still produce ones that already started.
Tomatoes are a tropical understory plant that doesn’t like excessive humidity or full tropical sun. We grow them in full sun in the U.S. because the sunlight here is less intense, but it still is native to warm but not hot mountains.
