No. And the potting soil may kill the seedlings. Damping off. . .go look it up.
I have used this on my tomato seeds with no issue. and I did get an outstanding success rate. The quantity you will need will be based on the trays /depth you are putting them in or pods. Best if you contact the manufacturer on an estimate of how much you will need. Or see if you can get a estimator online to calculate soil amount needed.Good luck on your seed starting!
Yes. It should work fine for your tree sprout.
This is a seed starter soil, so I am not sure if it will work for pineapple. Sorry, I can't help you.
I use it to sprout caladiums and elephant ears. Start them indoors in very little soil. Mix in the starter soil when I transplant outdoors unless I want to sprout something else.
6.0. Which is perfect
No it does not contain pesticide
About a two foot by two foot area. This is a very small bag and I used it in seed starter pods then transfered to the beds once the seedlings were large enough to plan in a garden.
