Some flowers on this hybrid Adenium dried and 'burnt'. Anything I need to be aware of?
Thank you.

nutritional deficiency ?

is this plant getting fertilized ?

Yes, it does. Mixed in the soil.

Water with 20-20-20 food once a week. Maybe I need to water every four days when blooming?

Thank you.

check your fertilizer for all the micronutrients (aka: Trace minerals) ...especially - Boron

There are 7 essential plant nutrient elements defined as micronutrients: boron (B), zinc (Zn), manganese (Mn), iron (Fe), copper (Cu), molybdenum (Mo), chlorine (Cl)

Boron is believed to be involved in carbohydrate transport in plants; it also assists in metabolic regulation. Boron deficiency will often result in bud dieback.

Chlorine is necessary for osmosis and ionic balance; it also plays a role in photosynthesis.

Copper is a component of some enzymes. Symptoms of copper deficiency include browning of leaf tips and chlorosis.

Iron is essential for chlorophyll synthesis, which is why an iron deficiency results in chlorosis.

Manganese activates some important enzymes involved in chlorophyll formation. Manganese deficient plants will develop chlorosis between the veins of its leaves. The availability of manganese is partially dependent on soil pH.

Molybdenum is essential to plant health. Molybdenum is used by plants to reduce nitrates into usable forms. Some plants use it for nitrogen fixation, thus it may need to be added to some soils before seeding legumes.

Zinc participates in chlorophyll formation, and also activates many enzymes. Symptoms of zinc deficiency include chlorosis and stunted growth.

Use any fertilizer that also provides these trace elements ....

Thank you very much for the detailed answer.

A great lesson. I truly appreciate it.

Thank you, again.

I use Osmocote 14-14-14 at every re-pot layered through-out the potting mix ...but that doesn't provide any of the trace elements .... so every 14 days or so I will water with Miracle-Gro All Purpose water soluable ... it does contain the trace elements

I do osmocote too but I recently added bloom booster water soluble for my plumerias and adeniums that are now done blooming.

Thanks for the tip on the miracle gro water soluble. I have them and use them for my other plants. Good to know I can use them on adeniums.

For dirt, I have only been using miracle gro potting soil. So far they have been responding well.
