Need Help with Al's gritty mix Concerned
Comments (11)Do not get me wrong I was not complaining about Al's gritty mix. I have seen, and heard thousands of testimonials, and I know it works- I was, and still am, worried that I missed some key ingredient that I was missing. With that said, for the time being I ordered some ph paper, and I will play with that thought once I get it. Ohiofem I have a couple questions for you because I have seen some of your posts in the Clivia forums. I bought some clivia plants off of ebay recently, after I had made my big batch of gritty mix. Some of my leaves are slowly yellowing- I know the plants were in duress because of being shipped bareroot. Besides gritty mix and foliage pro are you adding any other amendments, and in your mix are you using floor dry or turface? mandarin1- if my lily comes back, I think it will be a long time from now. It is completely laying on its side with about 15 out 20 leaves being yellow. However I still have hope- the rhinezome ( can't spell) looking roots on the top of the soil are real green. Hopefully it will bounce back when I gets warm and it go to it' annual outside summer vacation. I am glad your lilies are coming back Jala4260 I think you have a point. I have always manhandled new plants, I usually use a razor knife and cut an x Like pattern on the bottom of the roots to free them from their previous square or circular pattern from being root bound. But With Al's gritty mix it is the first time I have tried to remove all soil from starter plants. Plus what is up with that foam circular or square piece that now seams to be attached to the root base of all new starter plants. Anyways I have 4 large hayrack window boxes. I replace the liners and soil every 2-3 years. Last time around I had spagnum moss and all the plant roots dig in to it when I pull them out a large part of liner when with it so I went to the coconut liner this go around. I have filled them all with 1-1-1 gritty mix hoping to longevity and gorgeous flowers. Here is my question. Is it necessary to completely bare root starter plants for these window boxes. As I said earlier- I had pretty bad luck bare rooting and re potting a fuchsia and lantana- they dropped every leaf and half their stems- they look like potted sticks now, lol. I thought that maybe leaving some soil will help them slowly adjust to the gritty mix. What do you guys think or do in this situation? I want to thank all of you for responding to my questions, and pleas for help- it is a really friendly atmosphere...See Morere-pot in al's gritty mix or wait ??Heatstressed Gardenia! Help!
Comments (16)Here is the recipe (excerpt from the thread below): *For long term (especially woody) plantings and houseplants, I use a superb soil that is extremely durable and structurally sound. The basic mix is equal parts of pine bark, Turface, and crushed granite. The gritty mix: 1 part uncomposted screened pine or fir bark (1/8-1/4") 1 part screened Turface 1 part crushed Gran-I-Grit (grower size) or #2 cherrystone 1 Tbsp gypsum per gallon of soil CRF (if desired) Source of micro-nutrients or use a fertilizer that contains all essentials I use 1/8 -1/4 tsp Epsom salts (MgSO4) per gallon of fertilizer solution when I fertilize if the fertilizer does not contain Mg (check your fertilizer - if it is soluble, it is probable it does not contain Ca or Mg. If I am using my currently favored fertilizer (I use it on everything), Dyna-Gro's Foliage-Pro in the 9-3-6 formulation, and I don't use gypsum or Epsom salts in the fertilizer solution.* http://forums2.gardenweb.com/forums/load/contain/msg0214580016564.html...See MoreAl's 5:1:1 Mix vs. Al's Gritty Mix for Tropical Fruit
Comments (5)Yes you can, and in the short run 5-1-1 in may actually perfom better than the Gritty mix. But it will wear out quicker (break down) than the gritty mix. I tend to think of annuals going in the 5-1-1 mix, and perinnials in gritty mix. If you are going to be up-potting in a couple of years go with what you have. Either are a better choice than most anything you can find in most garden centers. Gritty mix makes future repots a dream, tip the pot over and you have bare roots.. Grading the pine bark is not fun, I hate it! A major concept of the gritty mix is based on particle size, larger particles have less surface area (by volume) and thus less water retention. 1/4 to 1/8 inch seems to be the optimal size, although due the screening process of pine bark and the thin strips I will let most 1/2 and under get in the mix (under 1/8 is not good either). If you are looking for Turface MVP check a local irrigation supply house, the stuff was designed for baseball diamonds so look in that direction. The dust is not good for the mix (particle size) The gran-i-grit is intended for chickens to help them digest grains. There are many other products other than gran-i-grit that will perform just as well. Look to a local farm supply house for the rock. Rock dust is not good for the mix (particle size) Gypsum is available at the big box home improvements stores. Gritty does dry out quicker than potting soil so you do need to water a bit more often. It is extremely difficult to overwater with gritty mix, that includes mother nature overwatering. Root rot is probably the number one killer of potted plants. After water, air is the most important thing you can give roots (most plants), more important than fertilizer. Gritty mix excels at this without drying out the root system. Gritty mix is heavy stuff, an advantage of heavy is the pot is less likely to tip from heavy winds. Al is a smart guy, it is such a simple concept....See MoreIs Al's gritty mix or 5-1-1 mix really any better than other mixes?
Comments (32)@Nil13 made reference to the Whitcomb 311 mix, which is an earlier historical attempt to create a more coarse potting soil for container plants. I think it is extremely helpful to read a document written by Carl Whitcomb that explains how he came on this formula by accident. Essentially what happened is he accidentally left nine test pots under a bench and everyone forgot they were there. They had successfully nearly killed all of their test plants by watering in a normal potting soil mix and the unwatered plants started to do very well. What I have started to realize is that any plant can do well in many different soil mixes, if you are able to carefully control the watering. This explains why so many people on this forum claim gritty mix is not as good for their succulents as their (fill in some random horrible soil with lots of small particles) mix. Inevitably those people are growing their plants indoors. They have enormous experience with their plant type and they know exactly when to water the plant. So that is the case of a very skilled gardener compensating for a very bad soil. What gritty mix does for me is let me grow succulents outside in very abusive weather conditions, without the plant dying. A plant can get a week of rain and it will still drain well. During Summer, gritty mix will tolerate a bit of overwatering, although you still really need to pay attention to not overwatering. Whether you make your 511 mix with perlite/peat, or with two parts Turface, or with lava and pumice, is probably in the big picture not going to be the deciding factor in whether your plants grow well or not. Success can be add with any of those mixes because the size of the particles allows the roots to breathe and prevents capillary action of water from bring the perched water table to the top of the pot and drowning the roots. Fine-tuning how you make 511 is a question of matching the plant type to the moisture retention of the soil and to the watering habit and climate exposure. Any 511 variant is going to do better than almost any commercial potting soil because of the larger particles used in the majority of the mix....See Morerina_Ontario,Canada 5a
