Radials on the ground or in the ground cannot be made resonant due to the

have as many radials on/in the ground as you can afford or have space for.?
Ground conductivity affects/interacts with the radial system too.? Many
operators start with 16 radials but often find that 32 or even 64 provide
better efficiency.? As you increase the number of radials, you increase the Q
of the antenna system by lowering the resistance (think resistors in parallel)
in the resonant circuit of the antenna.
Yes, though if you are in a very wet location one earth spike might do.
Only radials that are in air, above the ground, can be resonant.
