Propagating Oaks: Acorns Work, Cuttings Don't

English oak branches broken by cats won't root—oaks propagate almost exclusively from acorns. Named cultivars use grafting, not cuttings.

Acorn Propagation Protocol

1. Collect plump, mature acorns immediately after falling
2. Float test: discard floaters (insect damage/empty)
3. Stratify in damp peat/leaf mold at 32-35°F (1000+ hours)
4. Plant horizontally ½" deep in peat/sphagnum mix (April)
5. Grow in progressive containers (8oz → 16oz → 32oz cups)
6. Harden off mid-May, transplant to permanent site at 10-12"

Critical Details

• Never use garden soil—diseases, compaction
• White oaks germinate fall; red oaks spring—plant accordingly
• Remove acorn cap at planting to deter rodents
• Protect from mice, deer, mowers
• Water 1" weekly during growing season
• Fertilize lightly after first year

Timeline

Acorn → seedling: 1 year. Seedling → landscape tree: 3-5 years. Your cats' "donation" becomes a legacy project—acorns from this tree will carry its genetics forward.
