Plants taking a long time to set fruit

So, this may be a silly question, but in southeast Michigan when should my peppers and melons be setting fruit? I grew peppers from store-bought plants last year and definitely had some flowers on them about this time last year, and I have never grown melon before. I grew both things from seed this winter. The peppers seem to be taking a very long time to even get taller. My melons are flowering and flowering, but no fruit. They were all planted out late May. The peppers sprouted indoors April 9th, and the melon on May 14th. The first picture is of dragon cayenne, the second is poblano, and the 3rd is melon.

Melons and peppers are warm season crops, and really thrive in the heat. Did you have a milder or longer lasting spring than usual?

Do the melons have female as well as male flowers?

Try feeding the plants every time you water with a dilute dose of liquid fertilizer of your choice preferably something with a low 1st number. Store bought plants are forced with fertilizer and maybe your plants just need a boost. I have had some pretty small plants grow in Aug and produce gobs of fruit. Good luck.

Thanks everyone! I have 4 plants, and I am sure that there must be some females, but it am having trouble ID'ing them. I am just not seeing the swelling at the base of the flower. I feel like I saw some earlier in the summer, and that they fell off. We had A LOT of torrential rain and flooding. The garden with melons in it didn't have standing water, but the ground was completely saturated and my yard and parts of my other gardens flooded. I may just go out and start using a tiny makeup brush to go from flower to flower (hopefully) had-pollinating them. I fertilized with organic 4-3-1 fertilizer from Garden's Alive last week. I will apply a little more this week. I have not had to water at all this last month because of the rediculous amounts of rain.

If your not seeing swelling at the base of the flower it's a male flower....I suggest using a fertilizer with a high middle number (phosphorous) this is for flowers, fruits and roots. All the water can wash away many of the nutrients so you kind of have to go with what the plants are telling you. Or get the soil tested.

I finally noticed a few small buds on my poblano and dragon cayenne plants. I went out to hand-pollinate today and I think that all of my flowers on my melon are female, not male. I am hypothesizing that at the beginning of summer I had male flowers, and now they are mostly gone and all of my female flowers are opening. I will try a fertilizer with a higher phosphorous content. I have one that I use for tomatoes that I think is 6-6-2. Do you think that this would be okay?

No the first number ( nitrogen) needs to be lower.use triple phosphate if you can find it. Any god farm store should have it. Even the big box stores must have something with no or a very low first number. If you are dead set on using what you have it is probably better than using nothing. Good luck.

Nitrogen is for foliage and that isn't what you want. At this point you want flowers.
