Planting & Care Guide
-
Initial Soak: Water thoroughly both before and after planting to help establish the root system.
-
Handle with Care: Dig a wide planting hole and take extra care not to disturb the sensitive, deep taproot during transition.
-
Mulch Magic: Apply a layer of organic mulch around the base to retain moisture and protect young roots.
-
Establishment Era: Water regularly during the first few growing seasons; the tree becomes highly resilient once established.
-
Easy Grooming: Minimal pruning is required. Simply remove dead or damaged limbs as necessary in the late winter.
-
Light Feed: Fertilize lightly only if your soil is severely nutrient-deficient; this native species prefers natural, unamended conditions.
