why aren't there any flowers on my garden phlox??

central, NJ(Zone 6b)

I have about 5 garden phlox, orange perfection and tenor(red), the leaves look great they are all about 3 1/2' tall but no flowers or flower buds. They are located in part sun, (afternoon sun) they do not look wilted at all. They are 2 years old. Any ideas??

Hi Flowerjen, not sure if these phlox are perennial or annuals, but you say these are about 2 years old, so assume perennials, did they flower last year, if so, can you remember when, cant see the position being a prob, though I usually have them in full sun, if they are healthy in every other way, maybe a feed will help them, also you say they dont look wilted gives the impresion that they just might be suffering from lack of water, most perennials need a good drink and feed,as they use a good deal of energy to get through the winter, start into leaf and produce flowers for the summer season, I have some here in UK and they are not in flower as yet, but we have had quite a cool summer along with a lot of rain so I am keeping my eye on them for mould rather than no flowers yet, hope this helps and maybe someone else will come into the thread who can advise you better than I. good luck, Weenel.

They are perennials, no, they didn't flower last year. I figured the first year they might not but for sure they should have this year. They get the hot afternoon sun from 1-3pm and are NOT wilting, I keep them watered. Everything else in that garden is doing fine.I can not figure it out.

As they did not flower last year, like you, I would have said maybe just needing time to bulk up for next year, but this has not happened, so, if they are well watered, then maybe you need to look at the soil condition, as yellowing of the leaves also indicate soil problems, some plants need different neutrients to others and we need to add thing like blood/fish/bonemeal where others need a bit of lime, others are happy to just get some compost, so look up the care needs for your particular phlox to make sure they are getting what is required from your type of soil, if not, then either move them or add whatever they lack, it takes time to get the plants needs sorted, especially in a mixed border as we sometimes assume that if some plants are happy, they all should be, but this is not always the case, Like I have no good results from Carnations as they like a lime soil but mine is too acidic, maybe your the same with Phlox, wish I could help further, but try find out what they need incase it is as simple as that, Good luck, WeeNel.

I live slighty south of you flowerjen and my phlox (Nicky) has been blooming for almost a month. Orange Perfection has buds about to open. If they are only getting 2 hours of sun, I think you need to move them to a sunnier location.

Hi flowerjen,
The problem might be not enough sun. I planted some David phlox last year in a partly sunny spot. Only one out of the 3 had flowers, and they were pretty puny. This spring I moved them to a very sunny location and they all went gangbusters with big beautiful blooms. David is pretty easy to grow; yours might be more particular as to growing conditions. I would try more sun.

Ok, I guess I'll move them. Which is actually not a very far move. They are currently located in the long section of my upside down "L" shaped garden on the side of my house, the short section receives all the sun. Now I need to buy something to fill the spot that they are in. Oh, goodie!!! :)

That's what I love about gardening. There's always a reason to get more plants!
