Spray-N-Grow Fertilizer?
Comments (2)"... is the most effective gardening product you can buy" GMAB! ;o) Generally, the only time foliar nutrient sprays are used in agriculture are during periods of exceptionally rapid growth when Fe, Mn, or sometimes Cu are deficient or borderline deficient in soils. This product makes all kinds of claims (like Superthrive and Eleanor's concoction) that would be extremely difficult to substantiate. From a recent post: Some plants can absorb nutrients through foliage and sometimes stem tissue in ionic form, but the larger organic molecules of 'organic' formulas are unable to permeate cell walls. Water & its accompanying solutes are sometimes transported through the cuticle or epidermal cells of some leaves & twigs by diffusion, where it is adsorbed on the surface of plasmalemma (a kind of protoplasm that forms cell walls) where, by osmosis, it passes through cell membranes to cytoplasm. In some plants, water is taken in through open stomata as a secondary pathway. How much water can be absorbed through leaf & twig tissues varies by species, & within species, cultural conditions also have great influence on the process. Ambient temperature, relative humidity, leaf senescence (age), light intensity, nutritional status of the plant, time of day, all have impact on how readily water is taken in through leaves & twigs. Using a surfactant (wetting agent) also facilitates diffusion. The primary factor creating a barrier to diffusion through leaf cuticle tissues is the amount of (epi)cuticular wax present in epidermal tissues. In agronomic applications, generally only Fe, Mn, and sometimes Cu are applied as foliar nutritional sprays because the pathway via foliar application is often more efficient than the 'soil to roots' route. Note that these elements are in ionic solution when applied. Soluble salts present in foliar applications may or may not be available, depending on the plant, but the larger molecules are not - unless they are broken down by micro-organisms on the leaf surface (unlikely and inefficient if it was occurring) and diffuse into tissues via the same pathway(s) as the already soluble minerals. Based on the link you provided and what I know of physiology - I would save my money and buy a fertilizer that contained all the essential elements, or use a soil micro-nutrient supplement. Another thing: When you apply immobile micro-nutrients via foliar applications, the nutrients remain in the leaf they contact (because they are not mobile in the plant). This is a temporary fix, if the plant can access the nutrients, but it does nothing to fix the problem in newly emerging growth. Ca and all the micro-nutrients must be continually present in the nutrient stream to prevent deficiencies, and the only practical way to achieve that it is to have it available via roots.

Comments (2)I LOVE spray n grow! Do a test, spray one plant with it and do not spray an identical plant. You will see the diff. Best place to use it IMO is in the veggie bed, but I use it on ALL of my plants....See MoreHas anyone used 'Spray-N-Grow'?
Comments (1)Cork OK you can no longer say you havent had any responses. In going back through the archives I see that there were posts after yours and at least one before yours and this year too. I intend to go back and read some of those since I have taken the plunge. Even though the cats already out of the bag so to speak for me. In reading the directions there are some dos and donts of it one main thing is dont use the spray n grow within a few days of using any kind of organic chemicals or insectiside. Spray n Grow once it has dried on the leaves rain wont be a problem. And only make up enough of the mixture for what you will use in 4-6hrs, it may be ineffective after that period of time. I will get back on here wether my results be positive or negative....See Morespray-n-grow
Comments (7)I have used Spray n Gro for many years. It's purpose is to increase bloom production, not fertilize. I have had amazing success and live it. The one thing I dont normally spray are my hostas. I suppose if my goal were fabulous blooms I'd do it tho. Lucky you to have a mom who chooses to spend her money at a reputable place like Qvc rather than getting caught up in foreign lottery scams like my late mom did, bless her heart. At least products can be returned if need be. BTW the mfr of spray n gro sells a wetting agent called coco-wet and a liquid fertilizer that can be mixed all together (which is what I do). I think they have their own website. Good luck!...See Morealan haigh
