I have a hair particle system making a forest and I need those trees to grow, like in timelapse. I don't need them to grow from seedlings, it's more like appearing one after another in about 50 frames. I tried to animate the count, which is not possible and to animate the size, which is sort of possible, but for some reason only one keyframe can be added.

Unfortunately, the scale of particles cannot be animated, but there is a simple work around: animate the scale of the objects that are being distributed by the particle system.
