Whats the best to put mtk into to get tree seeds? Maples right?

Ye.

I have done both quests...so I have 15 workers. For max seeds I keep them on full maple, half teak.

Does teak give tree seeds?

Yes, teak and mahogany give nests

 

 

 

1 nest every 350 rare logs

You can kill giant mole and trade them for nest that have seeds/rings in them as well

Problem with giant mole is they are not normal nests they have random seeds in them 9 times out of 10 there horrible seeds like cabbage.
