As far as I know, there is no equivalent to the Gritty Mix on the market. However, there is a fairly decent bagged mix similar to the 5-1-1. Fafard produces heavyweight mixes (can't remember the exact designation) as well as a "Nursery mix," which has a high percentage of bark. That would be better than most mixes. Unfortunately, the cost of transporting the Gritty Mix would be prohibitive. Josh

"Did you later start using the gritty mix and abandon the basic mix?" No. I use the gritty mix for plants that will be in the same soil for more than a single growth cycle. I use the 5:1:1 mix for all my veggies and display containers for the decks & gardens. I usually turn the 5:1:1 mix into the gardens, beds, or the compost pile at the end of the season. You got the gritty mix right, but The 5:1:1 mix is 5 parts partially composted pine bark fines 1 part sphagnum peat 1 part perlite garden lime The granite for the gritty mix is usually found at rural elevators/feed stores under the name "Gran-I-Grit" (grower size) or Cherry Stone (#2 size).

Well, yesterday I used the gritty mix for the first time. I put a persian lilac seedling in the gritty mix (3-4-2) and a spider plant in 1-1-1. I am a bit scared as to how often to water since within a couple of hours the wick on the bottom was dry. I watered again and this morning dry again, so I watered again. Is this normal? The summer heat is not here yet and I am a bit worried about watering. Also the spider plant does not look too good, it is wilted quite a bit. I plan on putting some vincas in the 5-1-1 and see how that goes. I totally understand the benefits of the gritty mix but...are the plants going to make it if I water once a day? Also when is good time to start fertilizing the new potted plants and how much. I also plan on moving my african violet and the peace lily in the gritty (1-1-1) but they will be inside. Please someone help and build my confidence up...:( Michael

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.
