SUMMARY:Trident maple: January
DESCRIPTION:Dormant outside\, with the pot on the ground in a sheltered c
 orner or in a cold frame for spells of hard frost. The fleshy roots are 
 the weak point: do not let the pot stand frozen solid for days\, and do 
 not let it sit in water either. Check the soil every week or so and wate
 r only if it is drying. Study the bare structure and decide which branch
 es go. Basis (rhs): RHS: Acer buergerianum plant page (hardiness H6\, sh

SUMMARY:Trident maple: February
DESCRIPTION:The month for big cuts: a trunk chop or the removal of a heav
 y branch\, sealed\, while the tree is dormant and will callus from sprin
 g. Fleshy roots can be reduced hard at repotting\, but that waits for bu
 d swell. In a mild year the buds move in the last week\, and from then o
 n the tree should stay in one place rather than going in and out of shel
 ter. Basis (reference): Harry Harrington\, bonsai4me.com species guide (

SUMMARY:Trident maple: March
DESCRIPTION:Repot as the buds swell\, every year or two for a young tree 
 and every two or three for an old one\, because the roots fill the pot f
 aster than any other maple. A healthy trident takes a hard root pruning\
 , half or more\, and recovers. Set it in fresh mix at the same depth\, w
 ater well\, and keep it out of frost and wind for three or four weeks. N
 o feed until the leaves harden. Basis (reference): Peter Chan\, Bonsai M

SUMMARY:Trident maple: April
DESCRIPTION:Leaves open and growth starts fast. Protect new leaves from l
 ate frost with fleece on clear\, still nights. On a tree in refinement\,
  pinch each new shoot back to the first pair of leaves as it opens\, str
 ong shoots first\; on a tree being thickened\, let everything run. Water
  daily as soon as the surface dries. Full sun from now on. Basis (refere

SUMMARY:Trident maple: May
DESCRIPTION:Growth is at its fastest and water is the job: a trident in a
  shallow pot can need watering twice a day in a warm spell. Begin feedin
 g when the leaves have hardened\, with a balanced feed every week or for
 tnight for a tree in development and half that for one in refinement. Ke
 ep pinching. Check any wire from the winter every few days\; it bites fa
 st now and usually comes off this month. Basis (practice): General bonsa

SUMMARY:Trident maple: June
DESCRIPTION:Cut back the spring extension to one or two pairs of leaves o
 n every shoot you want to ramify\, and remove any shoot growing straight
  up or down from a branch. A strong\, established tree can be fully defo
 liated in early June for a second\, smaller set of leaves and finer twig
 ging\; not a weak tree\, and not one repotted this spring. Water and fee
 d as in May. Basis (reference): Peter Chan\, Bonsai Masterclass\; Harry

SUMMARY:Trident maple: July
DESCRIPTION:Water\, every day and more in heat\; a trident wilts fast and
  recovers\, but the shoot tips it loses are next year's twigs. Keep pinc
 hing the regrowth on a refined tree. Feed lightly. Sacrifice branches on
  a tree in development are left to run\; everything else is kept tidy. D
 o not wire in summer. Basis (practice): General bonsai practice for vigo

SUMMARY:Trident maple: August
DESCRIPTION:As July\, with the second flush pinched as it comes. Late in 
 the month\, drench the pot with vine weevil nematodes while the soil is 
 warm. Long shoots that have escaped can be cut back now without harm\; t
 he tree will still have time to harden the regrowth. Basis (rhs): RHS ad

SUMMARY:Trident maple: September
DESCRIPTION:Growth slows and stops. Two low-nitrogen feeds (a tomato feed
  at half strength) harden the wood for winter\; then stop. Water less as
  the days shorten and the nights cool. This is a good month to check the
  nebari and remove any root that has heaved above the soil\, sealing the
  cut. Basis (practice): General bonsai practice: low-nitrogen autumn fee

DESCRIPTION:Autumn colour in the second half of the month in a good year\
 ; stop feeding altogether. Once the leaves drop\, the twigging is visibl
 e and light wiring of young shoots can be done\, to be checked monthly a
 nd removed by April. Clear the fallen leaves from the pot. A tree in dev
 elopment can have its sacrifice branches cut back now or in February. Ba

SUMMARY:Trident maple: November
DESCRIPTION:Dormant. Water only when the soil is drying\; in a wet month 
 the risk is the opposite\, so raise the pot on feet and tilt it a little
  so it drains. Start the frost routine: sheltered outside\, cold frame o
 r unheated shed for the hard nights\, out again after. Remove any wire t
 hat is starting to bite. Basis (rhs): RHS advice: overwintering containe

SUMMARY:Trident maple: December
DESCRIPTION:Keep it cold\, damp and sheltered\, and keep the fleshy roots
  from freezing solid for days at a time. Check after each frost that the
  soil has drained. Light tidying of crossing twigs can be done on a bare
  tree at any time\; the big cuts wait for February. Order akadama and a 
 bigger training pot if the tree is being thickened\; it will need both i
 n March. Basis (practice): General bonsai practice for dormant deciduous
