A few clarifying assumptions: (1) the ages and number of trees can't be fractional (ie. half cut trees). (2) you're sure you didn't omit any information. Oh. I don't know; like the number of trees in the garden.
In which case, I can think of eight solutions. They are as follows:
(1) The oldest kid is 36. The other two are one-year-old twins. There are 38 trees in the garden, and the 36yo plays trumpet.
(2) The oldest kid is 18. The other two are one and two years old. There are 21 trees in the garden, and the 18yo plays trumpet.
...
In more concise notation, their ages can be:
1 1 36
1 2 18
1 3 12
1 4 9
1 6 6
2 2 9
2 3 6
3 3 4
Including practical factors like the unlikelihood of twins, the limited space in a garden for trees, the childbearing years of the father, and the competency of youth to play instruments, their ages are most likely 1, 4 and 9.

1) No, the ages are not fractional.
2) Yes, I did not tell you the number of trees. The only clarification I can think of is that at the end Adam should have said "my oldest /kid/" rather than "my oldest /son/". Even then, that part of the hint might still be confusing and/or misleading. There's something about the second hint that you missed.
