How-to: Pecan — Rio Ranch

01 Quick spec

Trees in the paddocks

40 ft

Spacing, wide silvopasture rows

6–10 yr

First real nut crop

Patience required: pecans are a slow, generational tree — a grafted improved variety may throw a handful of nuts by year 4–6, but a real crop is 6–10 years out and full production is decades. You plant these for the grandkids and the shade as much as the harvest. Plan for a long mast season every fall once they bear.

02 Planting & site

Stock & spacing

Buy grafted improved varieties (e.g. Pawnee, Kanza, Lakota) for reliable, disease-resistant nuts — seedlings are a gamble. Set bare-root trees in winter dormancy with the graft union above grade. Space them 40 ft apart in wide paddock rows so sun reaches the grass below and the canopies never crowd. Plant at least two varieties for cross-pollination.

Cage it hard + drainage

Every tree gets a heavy welded-wire cage — cattle rub on trunks and browse low limbs, and they will kill a young pecan in a season. Pecans want deep, well-drained soil and lots of room for a taproot; avoid soggy spots. Mulch the base, keep grass off the trunk, and water deeply the first two summers while the roots go down.

03 The year

When	What
Winter (dormant)	Plant bare-root grafted trees; prune to a central leader; check & repair cages.
Early spring	Apply zinc (foliar or soil) — pecans are zinc-hungry and go stunted without it. Fertilize lightly.
Spring–summer	Catkins shed pollen; deep-water young trees. Watch for nut casebearer and webworm.
Late summer	Nuts fill ("water stage" then dough); a heavy crop can drop limbs — don't overload young trees.
Fall	Shucks split and nuts drop. Gather what you want; cattle and poultry forage the rest as mast.

04 Problems & what to watch

The big ones

Zinc deficiency (small, crinkled "rosette" leaves) is the classic pecan failure — feed zinc early. Pecan scab in our humidity blackens nuts; choose resistant varieties. Nut casebearer & pecan weevil bore the crop, and webworms tent the canopy.

Cattle & alternate bearing

The main daily risk is the herd — a knocked-over cage or rubbed-bare trunk loses the tree, so inspect cages each pass. Mature pecans alternate-bear (heavy year, light year); thin a brutal crop to spare the limbs. Note: green shucks and wilted leaves are mildly toxic, but dropped nuts are prized forage.

05 Harvest & beginner mistakes

Item	Note
First handful of nuts	year 4–6
Real crop	6–10 yr
Harvest window	fall, after shucks split
Grafted improved trees (each)	$60–120
You need: cages + a long-term plan	see Orchard

Beginner mistakes to skip: planting cheap seedlings instead of grafted varieties; spacing too tight (they get huge); forgetting zinc; skimping on the cage so cattle girdle the trunk; and giving up too early — a pecan that looks idle for years is just building the roots that carry decades of mast.
