While humans are alone in their struggle to balance work and Netflix, all creatures wrestle with proper timing. With limited resources, organisms are pressed to use time wisely in all aspects of their lives. As University of Washington researchers recently discovered, this struggle even extends to something as sweet and pleasant as the fragrant scent of a garden flower. A team of UW biologists has identified a key mechanism plants use to decide when to release their floral scents to attract pollinators.
Their findings, published online June 29 by the Proceedings of the National Academy of Sciences , connect the production and release of these fragrant chemicals to the innate circadian rhythms that pulse through all life on Earth. The researchers studied these questions in the common garden petunia.
This white-flowered hybrid releases an aromatic, sweet-smelling fragrance in the evening to attract insect pollinators, such as hawk moths.
Kiley Riffell. Biologists have long recognized that creatures like plants, humans and even tiny bacteria all have circadian clocks — genes that keep their cells synchronized to the hour cycle of life on Earth.
To get odors out of houseplants, find the source and address the reasons for the stench. Determine which houseplant is the culprit.
Check the water catcher or drainage saucer. Remove decaying leaves and plant parts. Check the soil for fungus and algae. Avoid overwatering. Use soilless growing media for indoor plants. Do plants get rid of smells? Plants have numerous benefits — they produce oxygen, eliminate toxins from the air, improve air quality and add aesthetic value to a space.
Houseplants also make one of the most cost-effective ways of masking cooking smells and other unwanted odors in the home. Plants remove odors and beautify spaces.

Note that the Tobacco Hornworm and the Tomato Hornworm both eat tomatoes and other garden crops. Link to Research Article. Will planting petunias near tomato plants make a difference, or does this compound need to be isolated and applied to tomato plants to have an impact?
Which implies a commercial product. I have written about trap cropping etc here that does work. Can we extract this compound in a strength that may have an impact when applied to garden plants. But no, planting petunias next to something is not going to be any more effective than planting anything else unfortunately.
I stopped growing petunias in a large rectangular cedar deck planter that is filled with excellent potting soil, etc Why?
