  • Works very well to help establish young organic plants and seedlings!
Size: 10 oz
This root boost is an absolute game changer for transplanting young seedlings and sowing seed in soil that may not have well established microbial life. Love it! I use it every season just to give my all my plants a good start! It's worth every penny and super easy to use. It can be sprinkled in each planting hole, or you can dip your roots into the dry powder before transplanting. I see a noticeable difference in transplant shock recovery time for tomatoes that have been inoculated with root boost, versus those that haven't. A organic gardening must-have! ... show more

  • Your plants will love you!
Size: 10 oz
I finally pulled the trigger on purchasing this product. It super easy to use and very versatile. Within a week, my plants were looking healthier and growing like crazy! I purchased the larger bag. It will last me over a year and I have a lot of plants. I used it to sow my seeds this year and am seeing amazing results! A BONUS plus: there a ziplock to seal it! Will definitely purchase again! ... show more

  • Wow amazing product
Size: 5 oz
I'll be purchasing this from now on instead of xtreme gardening azo max ,I feel this works much better and its less expensive. I had plants that were yellowing(nitrogen deficiencies) and like 10 days after my first feeding with root boost they started coming back and now all the new growth is nice and dark green ,it has improved the health of all my plants though not just the ones that needed more nitrogen this stuff is the truth ... show more

  • Seems to help and good value Seems to help and good value

This was my first time using any type of rooting powder. Was a bit confused on using it but as tried it on some herb seeds and also cuttings from a philodendron. They seem to be doing well.

  • Put your seedlings in overdrive - a game changer! Put your seedlings in overdrive - a game changer!
Size: 10 oz
I use this combined with Xtreme Gardening Mykos. For bigger seeds, dampen the seeds in your palm then sprinkle with the combined products. For small seeds, sprinkle in the planting hole. I start my seedlings indoors in plug trays and sprinkle the roots when I transplant into larger cells, then again when I transplant into the garden. My seedlings are SO much bigger and sturdier with great root systems. The seedlings in the photo are the same thing, planted at the same time and treated exactly the same. Both products need root contact to work. They are also both alive, so don't pre-moisten. Store cool and dry. ... show more
