Speaking of cycads, I believe everyone is familiar with them, but many people always encounter the problem of yellowing leaves when growing cycads. So why do the leaves of cycads always turn white? How to remedy the whitening of cycads? Let's take a look together.

Why do the leaves of the iron tree always turn white?

If there are white spots on the leaves of the cycad tree, it is very likely that it has encountered pests and diseases, most commonly scale insects. Scale insects are insects that use piercing and sucking mouthparts to insert into the leaf tissue of the cycad tree to feed, which not only plunders a large amount of plant juice, but also destroys the leaf tissue, causing tissue fading and death.

You need to see clearly whether it is a pathogen or an insect pest. If it is a pathogen, you can buy a fungicide for it. If it is a white insect, press it to see if there is red blood. If so, it may be the white wax scale. The main drug used now is spirotetramat.

How to change the soil when the roots of the iron tree are rotten but the leaves are still green

When you find root rot, the first thing to do is to check the root system to see the degree of rot. Prune off the rotten roots and rotten tubers, and don't keep any. Then soak it in mancozeb for half an hour, and then repot it to let the roots grow.

It is best to use plain soil for rooting, that is, soil without nutrients, such as river sand. Plant the cycad in it, water it thoroughly with the mancozeb that was just soaked in the cycad, and place it in a cool and ventilated place. Spray the leaves with clean water every day to prevent water loss.

In this way, the river sand is kept moist, and roots will regenerate quickly. When the plant is stronger and more vigorous, it can be transplanted.
