Scent is missing from my scented roses?!

This may sound silly.. but my normally very fragrant roses are not fragrant during this first flush of blooms? What affects scent anyways? Double delight, Yves Piaget, W. Shakespeare, Midnight Blue and the likes only have a very vague scent this spring. In fact, when I went to the nursery this morning.. very few roses were fragrant. And I'm talking about the ones that are supposed to be fragrant. It's not my nose either. My Rose de Rescht is still fragrant. We had an exceptionally cold winter. Could that have done it? On the up side, my 'Radiant Perfume' which has NEVER emitted anything perfume like is smelling nice this year. SO strange... or am I missing something here?

RE: Scent is missing from my scented roses?!

Fragrance is basically oil and alcohol. There are other components, but thinking of them in this very simplistic explanation, makes it easier to juggle. There are a number of very volatile components to flower scents which must have the correct humidity and temperatures to volitize properly so we can detect them. It's possible, but unlikely, that a nutrient deficiency might alter the components the flower produces, but it is significantly more likely the temperatures, humidity and air flow are the culprits. Too windy and the scents evaporate more quickly and blow away. Too dry and they evaporate too quickly. Too hot and they evaporate too quickly. Too cold and/or wet and they may not perceivably express themselves at all. There are times you can apply your cologne and smell it for hours, while other times, you put it on and can't smell it half an hour later. Same thing.

I think if you carefully examine all the variables, you'll find some other change between the smelliest time last year and what the conditions are right now when you can't perceive the scents as well as you remember smelling them. Of course, medications, allergies and other conditions can incredibly alter our abilities to smell (and taste), also. Kim

This is not exactly on topic but I wanted to mention that I notice that a fragrant orchid I have inside is not always fragrant? I am blesses (or cursed) with an extremely strong sense of smell so I don't think its me.

Hi Lovelivegarden: I did an experiment with my herbs (basil, rosemary, and cilantro) by throwing blood meal, NPK 12-0-0 ... all the fabulous scents went away, replaced by pungent ickiness.

I threw acid high-nitrogen fertilizer on Mary Magdalene rose on summer and its fabulous myrrh scent went away.

High nitrogen fertilizer in spring time does that to roses. Check out what eHow wrote on excess nitrogen:

"Too Leafy: Plants that receive too much nitrogen may give off the appearance that they are healthy and thriving by producing lots of new, leafy growth. However, this new growth is often weak, soft and sappy, which makes the plant attractive to various pests and unable to sustain the stress of drought. And if the plant is aromatic, it loses much of its fragrance.

No Fruit or Flowers: It's difficult for fruit and flowers to grow when there is too much nitrogen in the soil. Fruit that does grow is distorted or doesn't ripen properly, while flower buds fall off or are disfigured if they do bloom."

Here is a link that might be useful: The effect of too much nitrogen

Every fall my roses have no fragrance. Just too cool. However - my friend's rose Chapeau de Napoleon (sp?) when it blooms in cold weather is astonishingly strong scented. I couldn't believe how strong the scent was. Roses just don't smell here in the spring/fall. But then ChdN is an old rose - so maybe that's why.

The scent is missing from my roses and I'm so disappointed! I have Rose de Rescht, Comte de Chambord, and Zephirine Drouhin and the David Austin Rose, Falstaff...and only sometimes if there a faint whiff of scent. I thought I was losing my sense of smell, but I can smell the aromas from my lavender, thyme, rosemary, mint and marjoram and anise hyssop (and my apricots which are stewing as I write!). So it's not my nose. Maybe my garden's too dry. Anyway, thanks for the information, glad to see it's not just me & my garden, & glad I joined this site.
