I gifted tuberose to one of my cousins and she complained to me that the leaves of the tuberose started turning brown and dry. You can see the picture at the top of this article. I will discuss the reasons for this and will also explain how to cure our tuberose.
In one of my previous articles, I discussed managing pests and diseases of Tuberose. But did not mention this leaf issue.
Let's start with the symptoms and some pictures. Brown leaves or dry leaves can be seen on a tuberose plant for many reasons and the experts usually find the reason by looking at the symptoms. It's important for us to identify the symptoms properly. Brown leaves are of many types. I will guide you to find and identify those leaves.
The solution is one step ahead of finding the symptoms.
Symptoms
Let me clear the brown leaves first. If you find old leaves turning yellow and then brown. It's totally fine and no need to take any steps. This is a natural process of leaving older leaves and putting the energy into growing new fresh leaves.
Check this picture:
You can zoom into this picture. You can find the tips of the leaves are brown and even some parts are damaged due to getting dry. Obviously, this is not a healthy tuberose.
Take a closer look:
These leaves are not too old to turn brown.
Reasons
If you notice any green leaves turning brown all of a sudden, it is because of one of the following reasons (or multiple reasons at the same time):
- The sudden climate change. ( You can't help much if this is the reason and planted in the ground )
- The lack of water for a long time.
- Sudden fertilizer application (more than enough) - Here you can find shrinking leaves and then they will start browning.
- Saltwater damage ( there is a chance if you live near coastal areas ) - Guideline: Save plants from saltwater damage
- Overwatering - You can easily identify this one as the lower leaves will start getting yellowing first and then the upper leaves will turn brown.
Based on my experience, I have listed the reasons in a specific order (based on the chances).
Cure your Tuberose plant - Brown leaves
If the weather changes suddenly ( for example sudden cold or sudden temperature rise ), the plant will go into stress and the leaves will turn brown.
For potted plants, bring them inside the house in frosts or extreme cold or cover them with frost cloth.
For sudden temp. rise, you don't have to do anything. It will recover over time. Just maintain good watering and the water draining system in the soil.
If there are no climate changes, check your watering schedule again. Touch the soil, if it feels dry water it. Due to lack of water, the tuberose plant can't transfer a lot of essential nutrients to the leaves as well as the water. It leads to the leaf dry and eventually turns the leaves brown.
You have to water it at least 2 times a week in the growing season ( If there is no sign of rain ).
Have you witnessed leaves shrinking before they turned brown? It indicates that your plant is overfertilized. Water thoroughly so that the fertilizer dissolves and flows into the soil as the water drains.
For overwatering issues (when leaves are browning and yellowing at the same time ), add some organic matter in the soil and add mulch. It can retain the extra moisture from the soil.
