Allamanda leaves typically turn yellow due to overwatering, nutrient deficiencies (such as iron or magnesium), or poor drainage. Make sure to provide proper care by watering the plant only when the topsoil is dry, supplying balanced fertilizer regularly, and ensuring good drainage.
Magnesium deficiency create dead leaves and yellow leaves on a plant.
Because when the Chlorophyll molecules - that gives leaves their Green color - disintegrate they can't make the plant Green anymore - Yellow is the next color to appear and in turn vanish to make way for the Red colors.
Incomplete
Yellow leaves on Carpenteria californica can be caused by a few factors including nutrient deficiencies, over watering, or poor drainage. To remedy this issue, you can try adjusting your watering schedule, fertilizing with a balanced fertilizer, or improving the soil drainage.
They have a magnesium deficiency. Magnesium is a mineral that is important in making chlorophyll (the green pigment that makes leaves green.) So a lack of it means that the leaves go yellow.

Allamanda is a climbing plant with yellow flowers, Croton is a foliage shrub from sun-tropical areas with insignificant flowers
too much water
Lily leaves turn yellow due to a lack of nutrients, such as nitrogen, or excessive watering, which can lead to root rot. This causes the leaves to lose their green color and turn yellow.
Carotenoids are the pigments responsible for the yellow color of leaves in autumn. These pigments are present in the chloroplasts of plant cells and help in the process of photosynthesis. As the green chlorophyll pigment breaks down in the fall, the carotenoids are revealed, resulting in the yellow hues in leaves.
Most likely it's the end of the peas' growing season in which they will turn yellow and die off.
I think it's a deficiency of nitrates, which help plants to produce chlorophyll, and which is the pigment that turns leaves green, and without it, leaves can become yellow.
A Allamanda should make its own food because it is a plant.
Yes it is,every part of the plant is poisonous.if you contact it might cause itchiness
Magnesium deficiency create dead leaves and yellow leaves on a plant.
In sub-tropical areas, allamanda cathartica is a soft shrub with clusters of bright yellow flowers at the tips of twigs. Not strongly fragrant, at least not in my garden.
