Getting the most vibrant blooms for your container and garden is not a rocket science. All you need are a few tips on how to use the right blend of soil, sunlight, and more, to achieve them easily!
Altering the soil pH might not be the answer to make every flower out there more colorful, but it surely does work for majority of them.
For example, if the soil is acidic (pH below 7), then it can make the blue and purple pigments in the flowers more intense. This works best with hydrangeas, delphiniums, and certain varieties of roses.
On the other hand, if the soil is alkaline (pH above 7), then it can make pink, orange, and red pigments in the flowers more vivid. This works the best with pink hydrangeas and roses.
Phosphorus (P) is the key element behind coloration in flowers, so it would be a good idea to look for a blend that has a higher number of it, like 10-30-10 and 15-30-15.
Do make sure that you are following the label for dosage and application.
When the plants are stressed, they respond differently to it, and this may, sometimes, can alter flower coloration in certain species. For example:
If you will start watering the plant slightly less (waiting for 3-4 days, after the topsoil goes a little dry before watering the plant), then it can help to intensify the colors of roses, geraniums, bougainvilleas, hydrangeas, and hibiscus—mostly the flowers that are well accustomed to grow in warm climates.
However, you might have to do it on a trial and error basis to come to a sweet spot, where the plant reacts to it by making its blooms more colorful!
Long lasting flowers are always going to maintain their vigour for a longer time, which means, they will appear more vivid and colorful, as compared to the blooms that last for a day
