Mike, Hey sounds like you have a great handle on both the 5-1-1 and gritty mixes! It took me a long time to find all the ingredients and figure out the fertilizer side of things, but once you do some reading of this thread and the previous eight threads it does make sense. Al was most generous with his time, both on and off-list, and answered many of my "newbie" questions. I'm sure your plants should respond much better using these soil mixes next season. My trees are showing huge root growth this season in the gritty mix. Granted, hunting down the ingredients, sifting fines, and mixing the soil it is a bit more work than just buying a bag of MG potting soil, but I have no doubt that in general plants grow better in the 5-1-1 and grit mixes with proper fertilization, watering, drainage and air movemnet through the root zone. The peat in the MG soil acts like a sponge and retains far too much water for far too long, preventing air from getting to the roots and keeping the roots soggy. I agree that typically the big box stores are not very helpful when it comes to finding the right ingredients for the soil mixes. Granted, a few list members have found the right size of pine bark, turface or even silica sand at a HD or Wal-Mart but typically in my area you have to go to local hardware stores, feed stores, etc. to find the ingredients. In my experience, if you go to HD or Lowe's and ask for turface no one has any idea what you are talking about. Sounds like you've already found some great sources for your materials! Good luck next season and be sure to keep us posted on how your plants do in the new mixes. Thanks Dave

Hi, Just curious, I have a question about sphagnum peat vs sphagnum moss. By mistake, I purchased sphagnum moss at the onset of making the 511 mix. I mixed one batch and used it for one of my 3 plants. When I realized that I was using the moss instead of the sphagnum peat, I threw it out and purchased the correct one and used it to make the mix for the other 2 plants I have. My question is this, is it possible that the presence of the sphagnum moss in this one container could somehow attract any pests? The reason I ask is that I saw about a couple of black, winged, fast-moving pests (maybe thrips or gnats?) around this plant today. Upon further inspection, I shuffled some of the top mix and saw a single, tiny larva(e) crawling in the medium and suspected that I have pests breeding in my container. And afterwards, as I shook the container, a fast crawling, winged pest climbed out of the mix, and up the side of the container. I sprayed this plant with some insecticdal soap and plan on repotting it using the sphagnum peat moss instead. So could this (sphagnum moss) be the reason for pest-sightings? I want to solve a potential big problem now, before the real bug season begins. By the way, I haven't watered this plant for like a week and it still seems to be moist inside. I had watered every 3 days prior to the last time.

Please allow me to explain some facts about the different types of sand. As a contractor and someone who has worked in a concrete plant you better know what type of snd you need for the job you are doing. With that said lets began. Sand is either dug up in a quarry or dredged from a pond, lake or a sand quarry that they hit a spring in and filled with water. All commercial sand is washed so it can be graded for size and type. You have to go out and dig up your own if you want to get unwashed sand ( which is not recommended for landscaping ) to be used as fill sand or what we call sandbox sand. First thing to fall out of the washer is mason sand. Next is concrete sand followed by fill sand which contains some clay. Next is gravel base and is made-up of lots of clay and small gravel.This is what you typically find on ball diamonds and clay tennis courts or as a base for a gravel driveway or path through your garden. It can be packed down so hard you would think it was concrete with a colored dye in it untill it rains. Dogs, cats, kids and husbands get in quite a bit of trouble when it rains because of this stuff. Next is pea gravel. This can be used to cover the gravel base or partly fill holes like lateral lines where you need good drainage or placed under downspouts to keep the water from making a canyon of you lawn and it gives it a decorative look. Just remember to use something to keep the gravel in place or your mower becomes a machine gun when you mow around It. A lot of people use it in flower beds and around the base of trees too for decorative look. Rock gardens look neat and pea gravel mixed with river rock works well for this. Next comes river rock. Used as I just mentioned in place of the pea gravel ecept not on lateral lines or sewer pipes or any other underground lines and pipes. Although it does work well for drip irrigation or soaker hose. Then the last is river stone. Good for decorative landscaping and filling in wash outs or anywhere you need the water not to erode the ground beneath them.

I personally think that anytime of the year is great for compost applications too. You may want to rake your lawn before you add your compost. Compost lasts longer than chemical fertilizers. The sulfates and nitrates wash way and deeper into the soil with every rain so you get an quick result as opposed to compost that lasts for years. ********************************************************** Fall fertilizing for lawns and shrubs begins in October... You will need aprox 4lbs of screened compost per every 100 square feet of lawn. The amount can be increased or decreased depending on the condition of lawn. ~Rodale & Staff Pg. 285-287. With compost, you should use it generously in your applications to yeaild the best results. ~Rodale & Staff Pg. 285-287. J.I.
