One of my plumeria cuttings has 2-3 inch leaves...yeah!! I believe I need to think about feeding it. One of my websites for plumeria recommend a 8-14-10 combo, but another recommends a 10-50-10 combo. Quite a difference. Any suggestions from you all in the real world. Thanks.
The 50+ middle number has been widely adopted, but some of the larger growers, including one in SoCal, have said that anything over 30 on that number is overkill. I think 14 is a bit low. I'm going to experiment this summer with different fertilizers on cuttings from the same tree to see if I can note any differences.
The one with the super high middle numer is a Bloombooster formula. I've actually used it on practically everything I grow a couple of times this spring so far. I would recommend it for established plants in the spring to give them the boost they need to flower. For cuttings that are just rooted and need to establish a well-formed root system and growth, I would recommend the regular fertilizer. Miracle Grow has both the bloombooster formula and the regular formula. If you were to visit some growers' places here in Southern California, you would see that they fertilize heavily and often for the best blooms possible up until September. Additionally, they use supplements such as Epsom Salt, Superthrive, and Spray 'N Grow. Bill's Perfect Fertilizer and Spray 'N Grow are often mixed together for the best results.
Cfarm, you could be right about Jack. I can't remember now. I thought he uses Bill's and Spray 'N Grow? He probably uses all kinds. I just used a Bloombooster too. It was a Schultz's Bloombuilder 10-52-10. I'm afraid I was too hot to be discriminating, and everything got sprayed: plumerias, seedlings, rooted cuttings, adeniums, passifloras, brugmansias, fruit trees, succulents, etc. Oh well...
Sorry for the delay in my "thanks" to all that responded. I left on a short vacation right after I wrote, and just read all of your reponses. I now have 5-6 inch leaves and another plummie has 1 inch leaves. Two more to go!!! I will run and get fertilizer this afternoon for my "mature" plant. Many thanks.
I bought my fertilizer this afternoon. One more question, I bought the granular type, I have pea gravel over my soil. Do I have to remove the pea gravel and work into the soil, or can I sprinkle over the pea gravel and water.
CaCajun, what kind did you get? Is it the water-soluble kind or the slow-release kind? If it is supposed to be mixed with water, then you can just water it in over the gravel. I personally would remove the gravel because it holds moisture in, and you can't see when the soil is dry or moist.
