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 to reach 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. Therefore it is not necessary to water.
What to do if we have over-watered? The idea 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.
