What is builder's sand? I notice a lot of plants require a mixture of sand for good drainage but I'm not sure where to find this sand. When I go to Home Depot or Lowes, they only have play sand or paving sand. Nothing that says "builder's sand."
Builder's sand is coarse sand that can improve soil drainage and is often found in the masonry department of most home centers. It has a much larger grain than play sand. If you are unable to find builder's sand, vermiculite will achieve the same purpose and should be easier to find.
Your duration for sterilizing soil in a microwave is much different for whether it is in a container or a bag. If I put two pounds in a bowl, it is 90 seconds. In a bag it, is longer. Why the difference? I will be using a bowl. Also, no thermometer needed? Thanks, Jane Cox
You can use a meat or candy thermometer to check the temperature.
No matter the container, bag or bowl, start with the lesser time of 90 seconds each time until you reach the temperature of 180 degrees.
Since microwaves vary in wattage, this will give you a safe way to heat the soil.
I was so happy to find this article today! I don't like to wear gloves in the garden unless I have to, and now I know why. :) Don't forget, the skin is our largest organ and it breathes, and enters our bloodstream in that way I would think - no need for a cut to get those lovely Mycobacterium Vaccae in. Combined with earthing/grounding benefits, it's sad that so many people look down on, both literally and figuratively, those who work in their gardens. Now I'm going to go read what you all have to say about spacing aubergines! :) Thank you! Anna (I'm not sure what the "site/private" choice is for my question. It's not really private, but I'd rather let you decide what happens to it.)
There are four different types of potting soils: all purpose, premium, professional and plant specific.
All-purpose potting soil is appropriate for adding ingredients, such as plant food (fertilizer). The type of fertilizer you use largely depends on what plants you're planting. What plants are you planting?
Premium mixes help augment water drainage and aeration with the addition of perlite and vermiculite. Some premium mixes include water-soluble or slow-release fertilizer. The bag of "TLC premium potting soil" should say if it contains fertilizer or not.
Professional mixes contain materials that are more completely processed and are usually very high quality.
Plant-specific soils are premium mixes designed specifically for a certain plant's needs, such as cactus or African violets.
What is a good commercial amendment to add to my clay soil (Knoxville, TN zone 7)? I cannot make compost fast enough to use with all my planting. Also, when I plant acid loving plants, should I be adding a specific acidic amendment right into the soil or spreading lime or Holly Tone on later?
Look for a bagged soils amendment called Clay Buster amendment, it is top notch for breaking up high clay soils. Test the Ph level of your soils first for the acid loving plants areas, then let that be your guide as to what needs to be done to bring the acid level into better balance. Go slow on adding anything to change the acidic level, it is easy to go overboard and create problems that are hard to correct.
Who can inspect soil for veggie garden previously treated with unknown weed killer?

How much leaf growth do I add to my topsoil to grow vegetables? For instance, the ratio of each?
I am not sure what you mean by leaf growth. If you are making compost to add to the soil, here's how to determine the ratio of green leaf material to dry, "brown" material:
