Rick's information is so good to read and has much to offer.
I feel that these are tools that each of us need, but people get too analytical and confused in the end. To the point it becomes too much and exhausting.
For the Adenium juvenile to adult try to stay close to ratios with 2-1-3, such as 9-3-6, 24-8-16.
These have worked for a lot of people growing Adeniums.
This of course is in container growing.
The Adeniums do not require high levels of P as many blooming fertilizers suggest.
I am no scientist and try to analyze and enjoy doing so, but I have seen people become overwhelmed with too much and this is not good.
The drainage issue in containers is very important, whether it seedling trays or pots. Definitely a problem with root issues and possible demise of the trees.
Thank You Rick for taking time to post this information.
