Medium_poinsettia Poinsettia with droopy leaves

We have had a poinsettia since last Christmas. As expected, the plant lost its red leaves a few weeks after Christmas and instead grew numerous green ones. A bit more than a month ago, red leaves started to reappear, and many more keep budding out at the end of each stalk (see photo).

The red leaves all seem healthy and firm. However, at about the same time as the red leaves started to appear, the green leaves started to become droopy - first only the lowest ones, but, by now, most of them. As they start to droop, the leaves turn from dark to light green, and often develop yellowish spots (see photo, showing a normal leaf on the left and a light green leaf with spots on the right). Ultimately, they turn yellow, wither, and fall off.

Maybe the withering of the green leaves is normal and just seasonal, but I am concerned that so many leaves are affected at once. Could this be some sort of pest, a nutrient deficiency, too small a pot, or a temperature/watering issue?

The plant is kept in a room that never gets below 10 degrees. We water it every five days or so, when the soil gets dry. We never let it sit in a saucer of water.

Many thanks and all the best,

Felix

Answer: Hi Felix,

Thank you for contacting Yates.

It’s common to see some yellow leaves and leaf fall during flowering for Poinsettia this time of the year. I would suggest to add some liquid fertiliser weekly to prolong the flowering time and promote more leafy growth. Try Yates Thrive Roses & Flowers Natural Fish & Seaweed+ Concentrate, the dual acting formula feed through both leaves and roots to boost healthy growth and prolific flowers.
