One of your three young Arbequina olives lost all its leaves weeks after planting in Arizona. The bark still shows green when scraped, though some upper branches are pale yellow. You've kept watering but wonder if it's a lost cause.
If the cambium (layer under bark) is green, the tree is alive. Olive trees can be slow to leaf out after transplant shock or cold snaps. Give it another month—spring is still progressing.
A leafless tree needs less water than actively growing ones. Check soil moisture before watering; cut back volume to avoid waterlogging. Overwatering a dormant tree invites root rot.
If no bud swell or new growth appears in 4–6 weeks, the tree likely succumbed to transplant shock. But don't pull it yet—olives are resilient. Many gardeners have seen "dead" olives resprout from the base months later.
Patience and careful watering are your best tools now.
