Start by using a fert with a lower NPK. Avoid the higher numbers like 24 -8- 16. You plants will not use it. Instead of mixing per instructions - full strength, mix a batch at 1/2 to 1/4 strength. And feed weak solution more often. Better for the plants. Also look for an organic fertilizer, this may help with leaf burn.
I also use a time release fertilizer like osmiocte and sprinkle a handful in pot. This will be good for the entire season. |

| Actually, 24-8-16 is an excellent fertilizer choice for an extremely high % of all containerized plants. It supplies nutrients in almost exactly the same ratio as that actually USED by plants, which allows you to fertilize at lower rates (EC/TDS) than fertilizers like 1:1:1 ratios and high-P products and still avoid deficiencies and excesses (toxicity). In fact, it would be very difficult to make a case for fertilizers other than 24-8-16 and the rest of the assortment of 3:1:2 ratio fertilizers as not being the most logical choice as your 'go to; general purpose fertilizer. I use Foliage-Pro 9-3-6 (another 3:1:3 ratio fertilizer) on all my containerized material. If you're still interested, Barb, you might find the accompanying link of interest. Al |
