If, then, unless stmt diagram. Would it be accurate?

I diagram my If, then, unless statements like this, would this be accurate way of diagram this condition?

• If, then, unless

----------------------------SPW--------------------------------------------/FB---------------------------FA
• EX: If [the seeds are planted in the winter,] then [flowers will not blossom unless fertilizer is applied.]

SPW: Seeds Planted in the Winter
FB: Flowers Blossom
FA: Fertilizer is Applied

SPW → /FB
........ → FB → FA

(The first arrow in the second condition is suppose to slant down from "SPW"

I actually do have a question on that too.
Here is how I would diagram it

SPW ---> FB ---> FA

I DID NEGATE FB. I learned that the part introduced by the word "unless" constitutes necessary and the other part consitutues sufficient , and you negate sufficient. That's how Testmasters prep course company taught.

Since the statement tells us "flowers will NOT blossom" , To negate that statement you take out the "not." That's how I arrived at my diagram.
