It greatly depends on how detailed and realistic you want it to be.

Look into Maya Help about xGen and Paint Effects

You just animate size attributes, such as Length. For more info consult the Arnold Manual.

understand but it seem like its spreading.

can you please tell me how can i give them growing something like this

[hamsterHamster · Accepted solution]

Open xGen Primitive section, there you can just set keyframes to a Length and Width attributes, e.g. frame #100 set keys for current values; frame #1 set both keys to 0. Go to Graph editor to adjust the key tangents.

Or you can edit the expressions for those both attributes, by changing the last line to:

$a * smoothstep(frame,10,30)

which will make your grass growing from frame #10 to frame #30. Change those numbers for your need, also function can be linearstep or gaussstep.
