Superthrive Bonsai Vitamins & Hormones
Superthrive has been around since 1940. It actually won the World Fair Science-Medal. Full of vitamins and hormones that plants (and bonsai) love. It is commonly used on bonsai during re-potting to promote root growth and reduce stress. Many bonsai practitioners also use it as a foliage spray to bring their trees to the next level by introducing vitamins to the foliage. This is done on a weekly to monthly basis depending on your process.
Superthrive is used in addition to bonsai fertilizer for the ultimate in healthy plants.
Paid for two day shipping and waiting too long for the shipment. Paying almost 12 dollars for shipping was not right. Will not do that again.
Only Quality supplies for my Bonsai trees. It makes a difference
One of the best I’ve ever seen
This is my second large bottle of superthrive. I like the new cap which is plastic. The former cap was metal and eventually corroded. That's how long I had that bottle. Of course, the product itself is great and I use it every time I repot my bonsai.
Fast delivery. Great service.
QUESTIONS & ANSWERSAsk a Question
What is the npk ration for this item?
Superthrive has no NPK value, it is a suppliment only and not a fertilizer. The exact recipe is a secret. Some say it's snake oil, some swear by it. I use it when repotting to water in and as a foliar spray once a week.

Plants & Tree Shipping:
We ship bonsai trees and plants from either our parnter nursery or our in house nursery depending on the tree. We may limit when we ship trees to help limit their exposure to extreme environments. For example we may not ship if it will cause the tree to sit in a truck over a weekend or holiday in very low temperatures or very high temps.
If we are shipping from our Harrisburg, PA location, the tree may arrive via any carrier, but usually UPS or USPS. Time in transit will be 1-2 days in the northeast, 2-3 days in the southeast, 3-4 days in the midwest and usually 5 days for the west coast.
Trees are shipped in custom boxes made just for shipping trees. Sometimes we wrap the pot and soil in plastic to prevent it from spilling out in transit. Many times we use packing peanuts as they have proven to be very reliable in keeping trees safe in shipping. If a box is noticiably damaged, please take pictures prior to opening.
Please Note: We do not ship plants and trees to California
