SUMMARY:Field maple: January
DESCRIPTION:Dormant and content outside. Shelter the pot from the worst f
 rost and from drying wind by putting it on the ground\, against a wall o
 r under a bench\; a cold frame is a luxury this species does not need\, 
 though it does no harm. Check the soil is damp weekly. Bare-root hedging
  whips for a forest planting are sold now and can be heeled into a box o
 f soil until March. Basis (rhs): RHS: Acer campestre plant page (hardine

SUMMARY:Field maple: February
DESCRIPTION:Structural work on a bare tree: the trunk chop on a collected
  stump\, removal of a heavy branch\, shortening a long leader. Seal the 
 cuts. Collected hedgerow trees are lifted this month or next\, with as m
 uch root as the hedge allows\, and potted in a free- draining mix in a d
 eep box. The buds move at the end of the month in a mild year. Basis (re

SUMMARY:Field maple: March
DESCRIPTION:Repot as the buds swell\, every two years for a young tree an
 d every three or four for an old one. Comb the roots out and remove up t
 o a third. A forest of whips is assembled now: root-pruned hard\, set in
  a shallow tray with the tallest tree a little forward of centre\, tied 
 in\, and left to grow. Keep repotted trees out of wind and frost for thr
 ee weeks. Basis (reference): Peter Chan\, Bonsai Masterclass (repotting 
 deciduous trees at bud swell\; group plantings)\; general practice https

SUMMARY:Field maple: April
DESCRIPTION:Leaves open. A late frost can blacken the new growth\, and al
 though a field maple recovers\, fleece on a clear\, still night saves th
 e season. Pinch the opening shoots on a tree in refinement to the first 
 pair of leaves\; let a collected tree or a forest in its first year grow
  freely. Water daily when the surface dries. Basis (practice): General b
 onsai practice for maples in spring\; RHS advice: protecting new growth

SUMMARY:Field maple: May
DESCRIPTION:Growth is fast and the pot dries daily\; water every day and 
 twice in a warm spell. Begin feeding when the leaves harden: a balanced 
 feed weekly for a tree being developed\, fortnightly at half strength fo
 r one in refinement. Keep pinching. Squash the aphids on the shoot tips 
 before they curl the leaves. Basis (practice): General bonsai practice: 
 feed after the leaves harden\; RHS advice on aphids https://rootandwire.

SUMMARY:Field maple: June
DESCRIPTION:Cut the spring extension back to one or two pairs of leaves o
 n shoots you want to ramify\; a strong\, established tree can be partly 
 or fully defoliated in early June for a smaller second set of leaves. A 
 collected tree in its first year is left alone to build root. Wire young
  shoots now if you must\, checking it every two weeks\; the tree is more
  forgiving of wire than other maples but still thickens fast. Basis (ref
 erence): Harry Harrington\, bonsai4me.com (Acer campestre: cutting back 
 and defoliation on strong trees)\; general practice https://rootandwire.

SUMMARY:Field maple: July
DESCRIPTION:Water is the job. Full sun is fine for this species and keeps
  the leaves small\, but a pot in full sun dries by lunchtime\, so water 
 morning and evening. Feed lightly. Watch for powdery mildew in a hot\, s
 till spell and move the tree somewhere airier if it appears. Tidy long s
 hoots. Basis (rhs): RHS advice: powdery mildews (air movement\, watering
 )\; general practice on summer watering of container trees https://roota

SUMMARY:Field maple: August
DESCRIPTION:As July\, with any second flush pinched as it comes. Late in

 k wire and remove any that is marking\; a branch set in June will usuall
 y hold by now. Basis (rhs): RHS advice: vine weevil (nematodes in late s

SUMMARY:Field maple: September
DESCRIPTION:Growth stops. Give two low-nitrogen feeds to harden the wood 
 and then stop. Water less as the nights cool. A good month to look at a 
 developing tree and decide which branches to keep for next year\; mark t
 hem\, but make the cuts in winter. Basis (practice): General bonsai prac

SUMMARY:Field maple: October
DESCRIPTION:Yellow autumn colour in the second half of the month. Stop fe
 eding. After leaf drop\, wire young shoots if needed\; the bark tolerate
 s it over winter and the wire comes off in spring. Clear fallen leaves f
 rom the soil. Bare-root hedging whips go on sale in a few weeks if you a
 re planning a forest. Basis (practice): General bonsai practice: wiring

SUMMARY:Field maple: November
DESCRIPTION:Dormant. Water only if the soil is drying\, which in November
  it seldom is\; make sure the pot drains\, on feet and tilted a little i
 f the rain is relentless. The pot can stay out in all but a hard\, windy
  frost. Remove any wire that is biting. Basis (rhs): RHS advice: overwin

SUMMARY:Field maple: December
DESCRIPTION:Leave it cold\, damp and sheltered. Check the soil after fros
 ts for ice-heave and drainage. Light tidying of crossing twigs is fine o
 n a bare tree\; the big cuts wait for February. Hedge-laying season is a
  good time to ask a farmer or a hedge-layer for the stumps and trunks th
 ey are taking out\, which is where the best field maple material comes f
 rom. Basis (practice): General bonsai practice for dormant native decidu
 ous trees\; collection practice as described by UK growers (estimate on
