This makes me look forward to the great taste of garden produce this summer! Thanks for the cheery puzzle- all I see out my window now is snow!

one of your better puzzles. Good job.

Once all of the red and green (and very little of the black) are solved, there will be no more line logic moves. I didn't look for a long time, but it seems edge logic will not help in the case either. But if you look at column 14 and rows 3-5 together, you will noticed that no matter where the 1 clue in column 14 is placed, column 15 will have a black cell in row 3, 4, or 5. This means that the rest of column 15 has to be dots.

After using some line logic on row 7 and column 23, you can use edge logic on row 3 to get some more dots.

Now again focus on column 14. If you try to fill in R4C14, then row 3 will be invalid. If you try to fill in R5C14, again row 3 will be invalid. So R3C14 has to be black. You will be able to do more line logic past this.

This is as far as I can get withe line/advanced logic. I'm going to describe a way forward, but I think it would be too much for most people to keep in their head (hence this one will stay "requires guessing").

Look at columns 25 and 26. The 4 clue in column 25 will either go somewhere in rows 5-11 or rows 13-16. If it goes in rows 5-11, then R8C25 would always be filled in no matter how it fits in rows 5-11. Assume R8C25 is black, then R8C26 would be a dot. This causes R13C26 and R14C26 to be black. Now assume that R13C25 through R16C25 are black. This makes R13C26 a dot and then R8C26 will be black. So no matter how the 4 clue is placed, EITHER R8C25 OR R8C26 has to be black. The same goes for the sets R13C25,R13C26 and R14C25,R14C26. This allows you to dot out most of the rest of rows 13 and 14. It also allows you to fill in R8C21 and R8C22 and dot out most of the rest of row 8.

The rest will solve with line logic. Very challenging puzzle!

Found to require some guessing by Gator.

With moderate look-ahead I could only find one place that the black 6 in row 3 would go. There was one other spot in the black that I had to do a little look-ahead but can't remember where it was. I don't think requires some guessing is the correct category but I'm nowhere near an advanced solver either.

Found to be solvable with deep lookahead by gator.

This is before we had the deep lookahead category. Updating to that. Thanks for pointing it out.

Your welcome! This was a fun puzzle to solve.
