Don’t panic if you notice that your tulip leaves are going yellow. Yellowing leaves on tulips are a perfectly healthy part of the tulip’s natural lifecycle. Keep reading to learn more about yellowing leaves on tulips.
So your tulip leaves are turning yellow. If your tulips bulbs are healthy, the foliage will die down and turn yellow after blooming ends. This is 100 percent A-Okay. The important thing, however, is that you must live with the yellow tulip leaves, even if you think they’re ugly. This is because the leaves absorb sunlight, which in turn provides energy to feed the bulbs throughout the winter.
If you are impatient and remove the yellow tulip leaves, next year’s blooms will be less impressive, and every year you deprive the bulbs of sun, the blooms will become even smaller. You can safely remove the stems after the flower wilts, but leave the foliage until they die down completely and come loose easily when you tug them.
Similarly, don’t attempt to camouflage the foliage by bending, braiding, or gathering the leaves together with rubber bands because you will inhibit their ability to absorb sunlight. You can, however, plant some attractive perennials around the tulip bed to hide the leaves, but only if you promise not to overwater.
If you notice your tulip leaves going yellow before the plants have even bloomed, it may be a sign that you are overwatering. Tulips perform best where winters are cold and summers are relatively dry. Water tulip bulbs deeply after planting, then don’t water them again until you notice shoots popping up in spring. At that point, about an inch of water per week in the absence of rainfall is enough.
Similarly, your bulbs may be too wet if you planted them in poorly drained soil. Tulips require excellent drainage to avoid rot. Poor soil can be improved by adding generous amounts of compost or mulch.
Frost can also cause blotchy, ragged leaves.

Anthurium plants have beautiful, lush foliage and produce bright, crimson flowers. When your Anthurium leaves start turning yellow though, you know you have a problem. Color change in Anthurium plants is not uncommon, especially when the plants are grown in containers. Learning how to identify environmental stress and provide the optimal habitat for your plant will help you fix the problem.
Why are my Anthurium leaves turning yellow? Reasons your Anthurium leaves are turning yellow include over watering, low humidity, excess sunlight, temperature stress, poor soil quality and insufficient fertilizer. You can easily identify and treat the cause to restore your plant to perfect health.
This article will help you identify the reason why your Anthurium has yellow leaves and help you create the optimal habitat for your plant, allowing it to thrive for years to come.
The ground looks like fall, but this is July
You may be a bit concerned if your yard suddenly looks like fall has come early, with tree leaves turning yellow and dropping like crazy. In most cases it’s not something to worry about as there are a few common reasons that trees drop leaves in summer.
The most benign reason is simply adaptation to conditions. Trees do react to the environment and adapt their growth accordingly.
Trees grow leaves in spring based on the conditions at the time. Locally, spring 2017 was (very) wet and temperatures were (relatively) moderate, and trees’ response was “Pleasant temperatures and plenty of water. Perfect conditions! Grow leaves, lots and lots of leaves!”
Then, our almost-daily rain—that’s what it felt like at least—stopped at almost exactly the same time as our normal summer heat hit. Now the trees’ response is “Yikes, hot and dry, I’ve got too many leaves losing too much water! Dump some quick!”
Tulip poplar with leaves yellowing due to dry conditions. These leaves will drop soon. It's not technically a drought, but the tree is reacting like it's in one.
Boom-you get October in July, break out the rakes. Leaves dropped for this reason will be yellow to tan with few if any leaf spots on them. Ten to twenty percent or more leaf drop is possible, but unless a tree is heavily defoliated for several years in a row, this normal adjustment to heat and dry weather doesn’t affect the health of the tree.
Of course every tree doesn’t react this way, as some tree species are less tolerant of hot humid weather and react more quickly. Even trees of the same species planted in different conditions can react differently. Newly planted (within a year or two) trees are particularly prone to drop as they haven't formed as many roots as mature trees. Remember to water your new trees regularly for at least the first year and during dry spells indefinitely to minimize leaf drop.
This young cherry has been in the ground for a year, and has fewer roots to find water than the mature cherry in the next picture. It's lost 90% of it's leaves.
An older cherry-it has still dropped leaves, but proportionately fewer.
Another reason for leaf drop is disease, and the same ‘wet spring followed by hot summer’ scenario is also a perfect set-up for leaf diseases. In this case the leaves will have significant spots or brown areas.
It’s important to rake up affected leaves and dispose of them to reduce the chance of spreading disease in following years, but again, unless the tree is defoliated repeatedly, it’s not too much of a concern. And just as trees have varying reactions to hot and dry conditions, some trees are more susceptible to disease.
(While technically you could spray diseased trees, that is better done 1) before the disease takes hold, particularly on frequently affected trees and 2) on smaller trees, as spraying large trees is often not practical from a cost/benefit standpoint.)
You can (and should) water your trees in dry periods to reduce stress, but don’t fertilize until fall-trees know how to deal with the conditions and you don’t want to encourage leaves that can’t be supported.
When should you be concerned with early leaf drop? If twigs and branches are dying you may have a more serious problem. You can tell dead twigs from live twigs because they are brittle and snap when bent, as opposed to live twigs which should still be plump, be supple and bendable. You should also be concerned if your tree defoliated heavily (over 50% leaf loss) for two years in a row, or if there is evidence of insect infestation causing drop.
Once your tulips have successfully bloomed, wouldn't it be nice to save the bulbs for next year? But to do that, you need to know how to care of tulip bulbs after bloom. Let's take a look.

Tulips are one of the most beautiful flowers to plant and they can perk up any corner of your garden. They are available in a wide variety of vibrant colors which allows you to be more flexible with your garden layout and landscaping. Tulips are spring blooming flowers. This means that they need to be planted in the fall when the temperature is mild but the ground should not be freezing or be covered in frost. Tulips blooms for a very short period and the flowers wither within a few weeks. Their foliage starts to wither after the blooming period is over and they remain dormant. However it is possible to replant the tulip bulbs the next year if you are careful to preserve the bulbs and take good care of them. You can of course choose to buy new tulip bulbs for planting the next year. But why be wasteful when with some simple procedures you can preserve the existing tulip bulbs. Also taking care of the existing tulip bulbs after bloom will save you lot of time and efforts in replanting new ones.
Once the tulip flowers have bloomed and the flowers begin to wilt, you need to remove the seed pod that is attached to stem of the tulip plant. You also need to get rid of any wilting and yellowing leaves from the plant. However make sure that the leaves and foliage are wilting or yellowing before snipping them off. This procedure of removing dead flower petals and leaves from the plant is known as deadheading. Deadheading plants deters the seeds pods from flowering again which in turn allows the bulb to get all the nutrients. It is important that the tulip bulb gets all the nutrients so that it can regenerate and flower the next season.

To deadhead a tulip flower bulb, first you need to wait until the petals of the tulip flower withers naturally. Please don’t get tempted to pluck the flower. Let nature take its course. Once the petals have fallen off, you will see the seed pod of the flower on top of the stalk. Snip it off with a pair of gardening shears. Make sure to snip the seed pod about one inch away from the top of the stalk. Over cutting the stalk is not recommended. When the rest of the leaves and foliage begins to wither and dry up and the leaves turns yellow, it is time to snip off the leaves. Pull back all the dead and yellowing foliage away from the bulb and carefully prune the dead leaves. Take care not to damage the stem and avoid watering the tulip plant.
Once you are done deadheading the tulip plant, let the tulip bulb remain underground for a few months. During the subsequent summer you can dig up the tulip bulbs from the ground and replant them in the fall. After you dig up the bulbs from the ground, spread the bulbs on a newspaper and allow them to dry. Store the tulip bulbs in a well ventilated and cool place until you are ready to plant them in the fall. Alternatively, you can let the bulbs remain underground, where they will remain dormant during the long summer and then bloom the next season. If you do go for this method of preserving the tulip bulbs, then make sure that they are “perennial tulips”.
Knowing the method for taking care of tulip bulbs after bloom, will help you to enjoy the beautiful blooms for another year. Preserving and taking care of the tulip bulbs is not difficult, once you know how to do it.

Tulips are hearty flowers that bloom in full force in the springtime. Most times, tulips are best when their bulbs are left in the ground year round, but your climate may not cooperate. If you live in an area with warm winters or you bought bulbs in the spring, you may have to store your bulbs so they’re ready to bloom next season.
