Age is the main factor in tulip discolouration. The color of the petals may gradually lighten over time or even change completely. Although most flower kinds may deteriorate with time, tulips and gladioli are the most frequently seen age-related color alterations. Although the reason for this fading is unknown, it is believed to be a way for the plant to let potential pollinators know how healthy it is. Old plants will need to be replaced if growers desire a garden with a bolder color because aging is a natural process that cannot be stopped.

Do tulips undergo seasonal color changes?
A few tulips that were given to us as potted plants were planted in the garden. When we planted them, they were white, but this year, they are blooming pink. We had no idea that a plant could decide at the last minute how it wanted to appear in the spring. Is this standard? — Lois
A: While it is uncommon for flowers to change color suddenly and drastically from year to year for a variety of reasons, many seem to do so.
The most typical response, which has nothing to do with your tulips, is rootstock issues. You can be certain that clusters of tiny pink flowers appearing unexpectedly on a yellow hybrid tea rose are on fresh growth shoots emerging from the root stock underneath the graft. With tree peony and herbaceous peonies, which are frequently grafted, this is frequently the case.
When the old blossoms set seed and the new seedlings return to the traits of one of the parents used to hybridize the plant, this is another way flowers appear to change color. Mothers frequently experience this. The new mum, which is often yellow, surprises gardeners as it crowds out the original plant because the new seedlings are frequently stronger than the original plant. As a fallen tulip seed wouldn’t bloom for years, it seems improbable that this is what occurred to your tulips.
Of course, there is also the matter of soil acidity, which may have an impact on the degree of saturation in particular in the hue blue. Hydrangeas, which are blue in Atlanta and pinky-lavender here, are an example of this.
Your tulips were white and are now pink, which may be the result of the weather. Cold nights may have activated the red pigmentation in the petals if the pink is faint and predominantly on the edges. White chrysanthemum, which become pink or purple at the tips of their petals in the fall due to the cold, are a good example of this. Additionally, the petals of tulips can shatter and develop vibrant color streaks. A virus typically causes that.
Despite this, breeders are aware that tulips and irises occasionally revert to a different hue, usually white, for no apparent reason. Irises have even been known to change color over time, turn white, and then, after being separated and replanted, return to their original hue. Nobody is certain what causes these changes, but it is unquestionably a mechanism of pigment genes being activated (or inactivated) by some mechanical or environmental element.
A: I cut my lawn yesterday, but to my dismay, it’s just covered in weeds I can’t identify. I’ve always used Weed-B-Gon diligently to keep the weeds under control. These weeds often form tiers of three leaves that range in size from approximately the size of a dime to smaller and are borne on short stems with small, rough-textured leaves. They produce tiny, purplish-pink blooms. Do you know if Weed-B-Gon will keep them under control, and if not, is there anything else I can use to destroy them besides Roundup? — Clyde
A: What you’re describing sounds like Lamium purpurea, or dead nettle. It is an annual and a member of the winter annuals category. Winter weeds that are annuals begin to grow in the spring after germination in the fall and winter. Gardeners are frequently taken aback by how swiftly these weeds appear to appear overnight, not realizing that they may have been developing steadily all winter. After blooming in the spring, they pass away and go dormant for the summer, only to reappear in the fall or winter when fresh seeds begin to sprout.
They should be pulled now to stop seeding because they are simple to remove. Use a broadleaf weed management treatment like Weed-B-Gon if there are too many to handle by hand. Avoid using Roundup since it also kills grass. Use a pre-emergent herbicide in the fall to stop the seeds from sprouting during the winter if you can’t get to them before they set seed. Speedwell, shepherd’s purse, and chickweed are among the winter-germinating seeds that can be controlled with pre-emergents, which should be treated in September.
Last Saturday, I removed some of the largest, healthiest dead nettles I have ever seen.
A: Each year, I have a few tulip patches that have many leaves but no blooms. Is there a way I can fix this? Why do you believe that is taking place? — Joni
A: It is challenging to maintain a decent stand of tulips blooming these days since they have been overbred and selected for colors and bloom size rather than lifespan. Some can be resolved in as few as two bloom seasons. The enormous, bloom-sized bulbs you planted typically result in a large number of extremely small daughter bulbs that aren’t big enough to blossom. The primary bulb is crowded by these tiny bulbs, which starve it and make it unable to bloom. This also occurs when tulips are buried too deeply.
Digging up the clump will allow you to sort the bulbs by size, retaining only the largest for replanting. Tulips are relatively contractile, which means that as the roots constrict, they draw the bulbs deeper into the ground. Therefore, you will have to search extremely far to find the bulbs.
I have lilac bushes; when should I prune them? I wish to make them smaller because they have gotten too big. How far can I cut them back? — Rianne
A: Lilacs should be clipped as soon as their blooming period is over, just like all spring-flowering shrubs. You will forfeit the flowers for the following year if you prune them later in the season.
Eliminate any dead branches first. Then remove skinny suckering stems all the way to the ground to somewhat thin the remaining branches. The top growth can then be pruned back by a few feet.
It is preferable to use pruning shears and snips to shape the extremely brushy Palabin lilacs with their tiny round leaves rather than cutting off entire branches if you have any of these plants. The majority of people trim this kind of hedge with hedge trimmers, which is good, but I like a more natural appearance, which can only be achieved by using snips and trimming by hand.
How come yellow tulips change to red?
They frequently arise as a result of a genetic mutation, an environmental reaction, or a virus. In reality, the streaked tulips that led to the Tulipomania obsession in Holland in the 1600s were brought on by a virus.
