    Ask a Question
    • Can this fertilizer be used simultaneously with other fertilizers or should it be used alone

      It can be used alongside of other fertilizers.  I do suggest carefully reading other fertilizer warnings to be sure it does not interact with anything in our fertilizer.  Our fertilizer is natural based, so does not contain chemicals.  We use this in combination with liquid kelp, hb101 and superthrive.  We do not use any chemical fertilizer on our trees.

    • Do I need to worry about the white mold that grows on the pellets?

      Mold growing on the fertilizer in the week or two after it was applied is totally natural.  The mold should grow only white in color.  The fertilizer is organic so it attracts anything that breaks down organic material, including beneficial bacteria and mold. The mold will go away usually within a week as it will break down and digest the part of the fertilizer it was after in the first place.  I notice this is more common in our nursery pots with organic dirt type soil and with high side walls. The excessive moisture from the soil and lack of air from the walls of nursery pots seem to give the mold optimal conditions.  Mold has a tough time living with good air flow and without water so I don't commonly see it on my show trees and other trees that have been moved to a boon style soil mix (akadama, lava, pumice).  Most of our bonsai are moved into our Professional Mix which is a Boon style ALP mix.

      This is common with nearly every good quality organic fertilzer.

    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
