Frequently Asked Questions

Q: What is Rootblast?
Rootblast is a granular fertilizer that's made from the following earth elements: 2% nitrogen, 1% phosphate, 2% potash, 13.8% calcium, 7.5% magnesium, and other micronutrients.

Q: Can Rootblast be used on all plants?
Yes, it can be used on all plants including annual and perennial flowers, vegetables, shrubs, trees, grass, and houseplants

Q: How often can I use Rootblast?
We recommend that you use it every spring, summer, and fall on all of your annuals, perennials, bushes, trees, grass, and houseplants, or every time you transplant them. Doing so will help your plants reestablish strong root systems. We also recommend it for use on young plants.

Q: Can I apply Rootblast more often than every season, or every time they're transplanted?
Yes, you can. It won't harm your plants if it's applied more often.

Q: Do you mix Rootblast with water?
No, Rootblast does not require any water. It�s simple to use. Just sprinkle it into the soil.

Q: Can Rootblast harm plants and flowers?
No, not when it's used as directed. We recommend waiting 10 – 14 days between feeding your plants.

Q: Can I use another fertilizer with Rootblast?
Yes, but we recommend that you wait 10 – 14 days before applying more fertilizer. Your plants' new root systems will then be ready to soak up more water and nutrients, helping them to grow strong and healthy.

Rated 4.6 out of 5 by 85 reviewers.
Rated 5 out of 5 by Plants are huge! We have a really hard time growing anything successfully in this hot Florida sun. I ordered this for my husband and he put some on or around every single thing we have in the yard including herbs, tomatoes, peppers, and shrubs. Within 2-3 weeks, everything has doubled or tripled in size except for the shrubs. The shrubs were really sparse and now they are much fuller and producing buds. We love this so much that I ordered the 10-gallon bucket so that we would have it all season long. I don't believe you can find it anywhere but QVC so try it. You will be amazed. 04-29-16
Rated 5 out of 5 by Good choice I have recommended the purchase of Rootblast to several of my gardening friend's two day's ago. 03-20-16
Rated 5 out of 5 by Love This Stuff! I've used Rootblast since it first came to QVC and have always been happy with the results on flowers and veggies. My son asks every year (but last year) what I do since his garden doesn't do as well. Truthfully never occurred to me that Rootblast was the difference until today when I reordered for this season. Now I recall running out last season after treating my perennials but before planting my veggies. Worst veggie garden I ever had! I'm ready to plant but not before my order arrives! 03-15-16
