Superthrive has been known for years as an additive to plants that has positive benefits.  Now they have fertilizer.  Not just any fertilizer, this is basically fish emulsion which plants and bonsai love.
Superthrive 4-1-1 fertilizer is a Certified Organic, OMRI listed Natural fish fertilizer.  Superthive 4-1-1 naturally breaks down and releases beneficial nutrients into the soil.  This is a product that is gentle on plants and is environmentally friendly as it allows plants to take up more nutrients which reduces fertilizer run-off.

Please Note:  This is fish emulsion and it does not have the best odor.  I suggest using on outdoor plants/trees or taking your plants outside to fertilize for a few days.

Not like the "Original"
This is fertilizer (fish emulsion based) and NOT the 'original' Superthrive which is not fertilizer, but rather a supplement. Superthrive is a brand. This is a Superthrive product and the only connection we (Superfly Bonsai) has with it is that we sell it. If you purchase the 'Original' Superthrive (which we also sell) it will have the same mixing instructions as it has for the past 60+ years. Totally different products, made by the same company.

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
