Sort off off topic - help with possible nutrient deficiencies

18 years ago

Hello all!

I would MUCH appreciate if someone could look at these 8 photos and tell me if they thin anything is wrong in each of them. The plants included are allamanda, plumeria, vigna caracalla and coral tree (I think its Coral tree)

Pictures 1, 2 and 3 - Vigna caracalla leaf close up and far away. It has been growing SO slowly, so I was thinking maybe it was missing some nutrient, the leaf in the picture is pretty white.

Pictures 4 and 5 are Allamanda. All the nutrient deficiencies i found online were Green veins and yellow leaves, but this plant has yellow veins and green leaves.

6 and 8 are Plumeria

7 is the coral tree - it has these funny white marks on the leaves.

    Hi there,
    welcome, being this is a plumeria board, see you are showing plumeria leaves. Please post pictures on your plumeria, if you have any questions. Perhaps you can find another board that can help with the other plants.

    Actually my plummy sprouts are looking the same way. They have looked great over the summer, but I am noticing their leaves are looking yellowish, like the one you have pictured. I am curious as to responses. Thanks for posting and welcome to the forum.

    And mine also! The cuttings' lower leaves are turning yellow and dropping off and the Mamas have green leaves with yellow veins. Help!!! Now I woke up to 45 this am and they're still outside (I'm in South Carolina - it's not supposed to be 45 at night for another 2-3 weeks!).

    Sorry - I just thought that because 3 of the 4 plants besides plumeria were somewhat tropical that it wasn't too badly off topic. I did warn that it was off-topic, and there is one pic of a plumeria.

    Im just going to try to fertilize the 3 non plumerias with a more balanced fertilizer - i only had been using bloom booster

    I think that your questions are right on topic. Who cares that some of the plants aren't Plumeria? Unfortunately, the gurus haven't been around the forum lately. Its starting to feel like a ghost town around here. Probably the season. At this time, some balanced fertilizer on the Plumeria probably wouldn't hurt either. Also, when I am having problems with a particular plant, I google it, with the word "fertilize" in the search, and usually come back with some good information. Good luck.

    Hi there,
    I wanted to say , I ment well, that if you had a problem with specialized plants, another forum may be able to help you..Of course, lots of us grow other plants..sorry, did not mean to offend.

    bottom leaves now are turning yellow on some plumeria plants if you are getting cool, plants can be going dormant. I am still warm where I live, but have some yellowing. sooooryy

    Oh but I don't want them to be going dormant yet! I am not ready! I protest this cooler weather (though it does feel nice) and our babies going to sleep. I repeat, I am not ready yet!

    Haha I guess it's just what happens with communicating over the internet!

    Hi Lauri,
    I too do not want dormacy to hit. I have waited soooo long for long leathery leaves, have them now, beautiful plants and realize the leaves are going to fall off and be a stick. ha We have odd weather now, getting very cool at night, which will shock them, and warming up in a few days. soooo will wait and see what fall weather does to the plumies. sometimes rains in my area in October and winds.

    My plumaria expert says that blossom booster or anything with such a high middle number is useless. In fact some of the threads by Al will agree.
    I use "Dynamite" 13 13 13...Even numbers right across the board. In fact most plants don't like such a high middle number, because your throwing the abilty off for the whole plant to be healthy, even the colors of the leaves by forcing flowers on your plants when you don't have to.
    How come plumies flower from the ground outdoors withou someone throwing so much middle number on them?
    In the ground, they are getting an even amount of nutriets to sustain over look, vigour, and health.
    I will send you an excert of why the middle number is useless.
    The "dynamite" has worked wonders for me. It is slow release along with micro nutrients and a well balanced fert.
    Just some excerts...
    "Whatever nutrients are available in excess, will be absorbed by the plant to a certain degree, and in some cases, this may lead to toxicity or even symptoms of shortages of other nutrients as toxicity levels block a plant's ability to take up other nutrients. Too much nitrogen will lead to excessive foliage production and less flowering. Too much potassium or phosphorus will not lead to ill effect, but will show up as a deficiency of other nutrients as it blocks uptake".
    "What about the "Bloom Booster" fertilizers you might ask? To induce more prolific flowering, a reduced N supply will have more and better effect than the high P bloom formulas. When N is reduced, it slows vegetative growth without reducing photosynthesis. Since vegetative growth is limited by a lack of N, and the photosynthetic machinery continues to turn out food, it leaves an expendable surplus for the plant to spend on flowers and fruit".

    "The fact that different species of plants grow in different types of soil where they are naturally found, does not mean that one needs more of a certain nutrient than the other. It just means that the plants have developed strategies to adapt to certain conditions, like excesses and deficiencies of particular nutrients.."
    "Most greenhouse operations will follow pretty closely to a 2-1-2 ratio of the primary macro-nutrients on most greenhouse crops with minor deviations based on tissue analysis and the effect of the growing medium. Most post-greenhouse fertilization will follow fairly closely to a 3-1-2 ratio, with some deviation. Again, this very closely mimics the range of the primary macros found in plant tissues".
    Read the thread......type in search....
    "Fertilizer Program - Containerized Plants (Long Post)
    very imformative article".
    I never use blosson booster, and all my plants flower Profusely....
    Hope this helps and greens up the leaves along with giving you nice flowers next time around..:-)

    Mike
