Why are the Leaves on my Sago Palm Turning Yellow
There are many species of mealybugs, the most common being the cottonybug, which is the one that, in turn, most affects ornamental plants. They appear on the underside of the leaves, and when you touch them you notice that they have a very soft touch. Their body is very fragile, so I recommend that you wear gloves so you don’t end up with stained hands.
They favor warm and dry weather, so you will see them mostly in summer. But they can be easily treated either with natural insecticides such as Neem Oil or kerosene oil or with chemical insecticides such as Dimethoate 40%.
Important: it can also have mealybugs in the roots. Water from time to time with water to which you will have added the indicated dose of insecticide to prevent or combat them.
Center Leaves Burned/Yellowed
This happens when we have bought a plant that was in a greenhouse protected from direct sun and we have put it directly in a very exposed area. Quickly the leaves in the center turn yellow and the whole plant can turn yellow in a matter of a few days.
What to do? In this case, it is necessary to protect it from the direct light with a shade net or, if we have it in a pot, to change its place, and to accustom it little by little to the sun, beginning in winter when the rays are less direct. Every day we will expose it a little more and more to the sun so that it has time to get used to it.
Yellow Spots on Leaves
The yellow spots appear especially after the first cold winter outdoors. Although it can withstand frosts down to 24.8°F (-4°C), it has to adapt little by little. It is not necessary to do anything, since it will put out new green leaves that year or the following year.
However, it could also be due to a lack of potassium, so it is recommended to fertilize it with potassium-rich fertilizers between spring and summer (Order it here).
Sago Palm Care Yellow Leaves
If it is only the tips, it is usually due to lack of ventilation. This is a plant that often presents this problem indoors. To avoid it, it is important to keep it, whenever possible, outdoors or in a ventilated room.
Lower (Older) Yellow Leaves
If your Sago Palm has yellow lower leaves it can be mainly for two reasons: overwatering or underwatering. The plant should be watered about twice a week in summer and every 4-5 days the rest of the year. When watering, the soil must be soaked well, so that it reaches the roots, otherwise, the leaves will start to turn yellow.
In case we do not know if it needs water or not, we can check the humidity by digging a little in the soil if we have it in the garden, or introducing a thin wooden stick to the bottom of the pot to see if it comes out with a lot of substrates adhered which would mean that it is wet and therefore it is not necessary to water.
What to do if we have over-watered? The ideal is to cut off the yellow leaves, and not to water until the soil or substrate has dried out completely. To help it further, we can water it with powdered rooting hormones. This way it will emit new roots.
