Site Preparation Loosen soil Little research to support amending the planting hole Some research supports amending the entire planting site
“Volcano Mulching” – Bad! No mulch over root ball – Good!
Proper Planting Techniques Wider, not deeper Remove soil and roots over root flare Top of root ball level with or above soil surface Backfill with existing soil or amend entire site No mulch or soil on root ball; 3” at edge No fertilizer at planting time
Establishment of Trees Takes 3-6 months/inch of trunk diameter For survival: Irrigate 2x week For vigor: Daily; then every other day (see Table 1 – ENH856) Apply 2-3 gallons per inch of trunk diameter
Establishment of Shrubs (3-Gallon) Takes 20-28 weeks to establish Water every 8 days in north FL; every 4 days in south FL Apply one gallon per irrigation (~1/4” rain) Apply water directly to the rootball Once established, only water during prolonged hot, dry weather (the first year)

Roots of this magnolia tree grew 8 feet in the first year after planting.

Native vs Non-Native Plants UF Research Compared 10 most popular native plants with 10 most popular non-native plants. Established them from 1-gallon plants. 20 replicates of each – half irrigated; half not irrigated. Four species of each responded to irrigation. Others did not.
Staking: 3 Rules of Thumb Stake only when necessary. Attach ties as low as possible. Remove staking materials within the same year.
