LOL, you all crack me up. Wish I wasn't right in the middle of main street or the pellet gun idea would be perfect...you know, not only greenie neighbors but anti-gun crowd too. I'd rather not explain myself to the sheriff, though he's a good conservative supporting the right to bare arms. I have a shotgun and I'm told a previous and rather notorious lady lived in my house who regularly used her shotgun on the neighborhood dogs if they used her lawn....even when they were with their owners. She thought she was decendent from the outlaw Belle Starr though I proved that wrong with a little research...makes fun town folklore though.

mosswitch-I'll keep it quiet-maybe mine won't hear it either. LOL Cindycrna-OOOHH-we can compare, Mine was planted September of last year-so I have a tiny little jump on yours-but I did move Wu two days ago-that usually slows them down a tiny bit. Can't wait for my Dancing Queen to get here to plant in front of Big Daddy and Stirfry is going next to Dancing Queen. Our Dancing Queen will be the same age. LOL

Thank you for the follow up post (laceyvail) but I don't feel like that answered my question. I know its late but gardening is about trial & error? Most of the "Greens" I am planning on planting can survive on less than 10 hours of daylight. In Mass, I still have 10 hours of daylight until mid November and then I never have less than 9 hours even up to the winter solstice so although I agree that my greens will not be their best I do believe they will grow, even getting them in this late. I could get lucky and not see a heavy prolonged freeze for some time. Its a roll of the dice I'm willing to try for a few seeds in trays. What I'm not willing to roll the dice on is ruining my 2015 Garlic crop. So back to my original question: Can I plant on top of my newly seeded garlic? or (to ask a different way), will the roots of leafy greens adversely affect my 2015 Garlic crop, which is planted at a depth of 6-8 inches? Looking forward to hearing from the GW community. Thanks again in advance.

Chicken grit is not a substitute for turface, but could be used alone - each ingredient can. Particles of any substrates used should be as close in size as possible. So mixing small grit and larger gravel doesn't really help. Try to get more uniform mix, it will work much better. How small is the grit? It may be god size. Here is photo of some of the grit that is smaller size - I use it mostly for rooting and very small plants. There is also little bit of perlite (I am adding quite a bit more) and some turface. As you can see, they are quite close in size: In second photo, particles a little bigger. There is hardly any perlite there yet, but it will be of same size as the grit: You can use just C&S soil and (coarse) perlite mixed 1:1. I don't use that mix but many do and are very happy with its performance. Here is a photo of it borrowed from Crenda - Thank you Crenda!You could use grit+perlite; you could use grit+perlite+pumice; you could use grit+perlite+turface...and many other combinations, of many other ingredients/substrates. I have potted succulents in grit only and also perlite only - they are both just fine, but grit only pot is quite a bit heavier and needs to be watered more often. Perlite only is very light. So those are bit of extreme, but work well anyway. I use mix of equal amounts of grit and coarse perlite and add small amunt of turface (between 10-20%). Turface retains more water than grit & perlite, I would not use it 100% alone. I use lots of perlite - many don't like it and use pumice insted...but I can't find pumice easily and inexpensively, so perlite it is. It works really well. Aquarium gravel could be used too. Much of it is colored, and it is more expensive to buy. I got some (about 2gal) free from freecycle/kijiji but it is colored green and quite large, so I use it sometimes for top-dressing. I also have very small amounts of smaller a. gravel (also recycled so it was free :) that is pink, blue and light green, some grains are occasionally visible in some of my photos. It has been mixed well with other ingredients since I reuse mixes if repotting: depending how it 'looks', I usually rinse it, occasionally adding some bleach, let drip-dry in colander and it gets mixed in again. All of this may look quite complicated - but it really isn't. Do not get totally obsessed about it. It gets easier and simpler - eventually.
