Step 5: Additional Questions

Had flowers ever been seen on these trees?

• Answer: Yes, 1 flower 1 time.
  This indicates that the trees were mature enough to produce flowers, which is typically only three years from grafting.

How did other apple trees in the neighborhood fair that year?

• Answer: Others on the adjacent property, the Denver Botanic Gardens, had flowered well and were setting fruit.
  On a larger-scale, a late freeze had not occurred that spring.

Was there a cold snap that could have settled in the low-lying area of the fruit trees?

• Answer: Unlikely, as many cold-sensitive plants were growing without damage.
  On a local scale, there were no signs of freezing temperatures during critical stages of development, as other plants, more sensitive than apple flowers, were not damaged at all.
