Excellent product and fast delivery.great company to deal with.
This was the quickest delivery ever, arrived next day, thank you Gardenshop. I just started using it, I'm sure I will see a difference
I have used this stuff last couple of years when transplanting my flower seedlings...My petunias (home grown from seed) grow at least triple the size of normal seedlings and they catch up on growth and performance all shop bought petunia plants (which have been planted in greenhouses, optimal conditions a month earlier at least). So super stuff...Use for any plant!!! My petunias are just example.
Super product. I've used this for the last 10 years + and would never plant anything without it.
Really delighted with the service from Garden Shop and can finally buy at home at a very reasonable price. Will definitely be using the Garden Shop for future purchases. Thank you very much. Best regards, Julie
