Al: I would value your opinion on this test of mine...
Comments (29)I have a Dwarf Cavendish Banana too. :) They are both fine. I trimmed back the Banana in late Fall (all except 4-5 newest leaves). The Lime I bought last Spring. It was about 10 inches tall then & is about 2 and 1/2 to 3 feet tall now. They are in my basement below the house, sealed area with a tiny bit of air intake & that's it...much warmer than the Winter here. In fact, I need to check on them! I have watered them very little since they went down there, like I read I was supposed to do...Anyways, i've gone off on a fruit tangent the last 2 years. I also have Blackberries, Raspberries & Strawberries that should produce this year. I'm growing new Mexican Papaya, Grapes & Pomegranate too. Yet to make it on to my blog cuz the berry plants are overwintering fine, but have little foliage. The Strawberries, the same. The Mexican Papaya I grew from seed & are about 3 inches tall at 3 months or so old. The grapes are arriving from Jung any day now. I'm excited to throw a twist into things this year again with the fruits & also some of them should produce this year too! Time for that perfect garden addition of sweet to an already home made bbq sauce...muahahaha. - Steve...See MoreFertilizer for container plants
Comments (3)You're not alone in the way you think, but plants don't USE nutrients in a 1:1:1 ratio, so it makes little sense to supply it that way. Plants tend to use nutrients in a ratio that varies surprisingly little from plant to plant. What varies is the o/a amount of nutrients various plants require. On average, plants use about 6X more N than P, and about 3/5 as much K as N. When the calculations are done that adjust for the fact that the P & K % reported aren't the actual amounts of P & K IN fertilizers, you'll find that fertilizers with 3:1:2 ratios come closest to supplying nutrients in the ratio at which plants actually use them. There is a decided advantage in using a ratio that mimics usage because it allows you to fertilize at the lowest level possible w/o deficiencies. Examples of 3:1:2 ratio fertilizers are 24-8-16 made by Miracle-Gro and many others, 12-4-8 Miracle-Gro, and Foliage-Pro 9-3-6, which is favored by many on the forums. Al...See Morenpk % vs npk ratio
Comments (15)Fertilizers have reported NPK %s that are listed on the container, and identify the % Nitrogen, Phosphorous pentoxide (P2O5) , and Potassium oxide (K2O) in the product. When discussing fertilizer %s, separate the numbers representing the NPK %s with a dash (24-8-16, 12-12-12, etc). To determine the ACTUAL % of P and K in fertilizers, you multiply the amount of P2O5 reported by .43, and the amount of K2) reported by .83. Fertilizer RATIOS are the best reference point for determining what fertilizer is appropriate. If we consider only the NPK RATIO, 9-3-6, 12-4-8, 18-6-12, 24-8-16 would be equally appropriate (or inappropriate, if you prefer) because they are all 3:1:2 RATIOS (based on the amount of NPK REPORTED). Essentially they will yield approximately the same strength solution if mixed to the manufacturers specifications. Specifically, 24-8-16 diluted in twice the amount of water as the same measure of 12-4-8 yields the same concentration of elements and the same amount of each element per any given volume of solution. Note that when discussing fertilizer RATIOS and to avoid confusion, we should use a colon (3:1:2, 1:1:1) between the numbers to indicate you're discussing the fertilizers nutritional RATIO, rather than its NPK %s Usually, when we suggest or discuss ratios, we use them as a function of the REPORTED NPK %s, rather than the ACTUAL NPK %s - it's just much easier than having to do the .43 and .83 factoring and plugging the results into whatever it is you're factoring. Maca - I didn't realize I might have answered your questions here on 'Containers'. I looked all over the 'Citrus' forum yesterday or day before, and only stumbled on this thread today. I hope that between all the good folks that offered help, you got all the answers you needed. Best luck. Al...See MoreFeeding Calcium to Cinense - SmokeMaster
Comments (24)I think the KEY IS-Calcium Acetate. Dolomite Lime just add Mag. to the mix. Other Acids can do a Ca. thing. IF the net is right???? Acetate can be used by plants ON CONTACT. If the stuff I read AND seems to work is right...FOR MY GROW. I'd bet any organic thing inolved in an Aetate COULD probably work for all kinds of home made organic nutes. As I understand it,Acetates/Vinegar produced stuff. Not a problem as far as being too acid etc. Doesn't mess with PH,What I make is WAY less than 5% acid of Vinegar. At 2 or so oz. per Gal. or less,I doubt it has ANY effect on PH. I've used it without problems in my Hydro grows. BUT I change nutes often. Cheaper and LESS time consuming than messing with PH up or down... Smoke...See Morejrl1265
