Besieged achievement

[Banasou]

Tell me pls, how can i otain this achievement? On which level it's easier to do?

I know this is a years-late reply - hopefully you've gotten the achievement in the meantime. But if, like me, you put the game away for a few years to come back to it later and still haven't gotten it, I just got it (finally!) completely by accident. It turns out that laser pods won't kill trees (at least in the HD version - have not confirmed this in classic), so I left one of my planets alone while it was being harassed by an enemy laser pod. Voila, five minutes later, achievement! Not sure how to create such a situation intentionally, but given the enemy AI's love of those darn laser pods, just play and watch for an enemy to send a pod in to a planet you've got only dyson trees on. When you see it incoming, vacate your seedlings so they don't kill the pod, then just let it circle until five minutes have gone by. I think it helps if you have fewer trees on it - so maybe play a map with lots of planets, spread out to as many empty ones as you can find/defend, build only one tree at a time, and then let the bad guys in?

Good luck!

not sure about easier, but early missions, when you have to take the big energy yellow asteroid to the left by grabbing the unoccupied equal energy asteroid to the right, I think its # 5, maybe 7

theres 3 to 6 low energy tiny asteroids that should get attacked by 2 to 5 grays at a time, dont build more than one plant on those, make sure to reduce the attackers to about 2 (1 is fine) by keeping a couple active fighters, capture all escape routes with your main army, so they stay attacking and dont retreat, and then leave them be, keep removing reinforcements so the attackers dont get damaged further

Finally got this stupid achievement, but an enemy flower staying on an undefended asteroid of yours for five minutes is by far the best method. It won't go down easily if you have seedlings spawning there, but it also won't overwhelm and take over your asteroid like a group of enemy seedlings would.
