Mutant Seeds?
Only visit neighbors with a spade/shovel count going, tap their mutant walking corn usually found on roads. Don't drop seeds in towns without a spade count. You get more seeds from tapping mutant corn...

I try to reciprocate, but why does it matter if you can't? They are placing their seeds in your SF mainly because they want someone to squish them quickly. A secondary reason is that you might send some of your seeds to their SF.
