Getting vines should be an easy task when you get to bees
7 nature essence gives you 16 vines. Vines also compost. I had a ton of nature essence and practically no use for it until I started composting vines. You'll get a nice amount of garden soil in no time
I didn't know about the acclimatiser, so I ended up not caring about the quest line and just started breeding bees in a Magical Forest to get the imperial and industrious in order to get an alveary going. Later I figured out that Transmutive bees produce silky combs and they will work perfectly fine in a Magical Forest. It took a little while to breed them, but now I'm just waiting for them to produce enough silky combs. You need a ton to get enough silk wisps. Soul frames helps breeding faster and getting higher chance of mutation.
And by the way, for silverwood saplings... Once you get lucky enough to get your first magical forest setup a dark room and wait for a Pech Forager to spawn. Gambling for gold blocks will get you silverwood saplings much quicker than having to go through the crafting process. I used a name tag to name mine so he won't despawn on me. I think that is the only way to get mana beans as well (not sure if there are other ways)-
