We purchased two olive trees last fall and immediately replanted in 44 cm ceramic pots. They sat on a south-facing deck overlooking False Creek through the winter with their pots wrapped in bubble wrap, and were covered when the temperature dipped below zero. We fertilized with 18-4-8 tree and shrub fertilizer in April. Now that the weather has warmed, we've noticed a light yellowing of the leaves from the tips of each branch. It's especially noticeable at the top of the tree. The spread seems to have subsided somewhat, but we're concerned the roots may have been damaged. Any ideas on the cause?
