Hi all,

Has anyone experience this problem with your Calathea Lutea?

Had being watering quite regularly & added compost of dead leaves & soya bean residue on the root area.
The plants on overall looks ok but just some of the leaves are yellowish & looks like burnt.

Cheers, Jacob

guys,

i think the problem went off on its own.
now, my problem is that they are not growing tall enough.... LOL
my plan was to have calathea to provide some sort of screen to block a direct view to my neighbour house.
the walls the developer made are merely 4.5' which i dont feel having much privacy.

anyway, any good idea about boosting calathea's height would be greatly appreciated.
i've posted some of my recennt calatheas pic in the garden forum...

cheers, Jacob

Overwatering can be the reason yellowing the leaves. When you water, water to drainage. Don't leave the plant sitting in that drainage for any extended time. That just allows the sitting water to be taken back up. Another reason could be nutrients. You plants do not get enough nutrients or you have fed them more. Feed them if your plants are lack of nutrients or flush the plants for nutrient solutions.

they will eventually get tall if the soil is fertile and well drained, and they are grown in part shade.

Provide a calathea with moderate light. Water your calathea frequently enough to keep most of the potting mix moist. When the top of potting mix is dry but there's moisture several inches into the soil (gauge by sticking your finger down into the potting mix), it is time to water. The water must be room temperature, so let the water sit in your watering can for 15 minutes before watering.
