Well the premise of the seedling nursery is pretty simple. You can use it to store your seedlings, water them inside it and harvest for water. Pretty straightforward. Zynga has thrown a couple of pleasant surprises our way with this feature however. Check out the details below and please share with friends if you find the post helpful.
First of all you can water your seedlings from the inside of the nursery using watering cans from your gift box. If you water from the outside, you will also have the option to use your special delivery boxes.
In the second surprise, when you water a seedling inside your seedling nursery, instead of ONE friend being able to claim as from a normal tree post, FIVE of your friends can claim a full grown tree from your post.
The third rather nifty benefit of the seedling nursery is that when you grow a tree from inside of it, you get not ONE but TWO of the tree for yourself in your giftbox. In many cases the second tree will not appear until after you REFRESH your farm. At this time, we are not sure whether or not this is a glitch. If it should change we will update the post as we find out that it has. Update: The two trees for yourself was indeed a GLITCH and has been PATCHED.
