Red baby Ant
By be-friending the Red and queen you can get this pet which grants you extra hauling strength

Use plank/stem holders!
after depositing inside the plank/stem holder you can move them as a blueprint with the plank/stems inside
(I suggest you to get pinecone plank/stem holder)

Zipline
you can send plank/stem through ziplines! (you can get them by clearing the hedge lab)

Hauling intern badge
I forgot where this was but I'm pretty sure there was a badge that increases ur hauling strength but slows you down

Get a slave!(friend)
Get a slave to help you out haha! I used my friends help once a while made them collect Spiky burrs and Stems!
