~ Days 13 - 20 ~

~ Day 13 ~
The plants look pretty much the same today as they did on Day 11. In Box 1, the carrots still look fine, and the new sunflower plant hasn't grown much yet.

In Box 2, the sweet potatoes are still growing fine as well.

In the round pot, the extra sunflowers are doing fine. The smaller sunflower (that I removed from Box 1 on Day 11) - i.e: the one that was eaten by a bug - hasn't started to grow any more leaves, though.

~ Day 16 ~
In Box 1, the carrots still look relatively unchanged - however, something is happening with the sunflowers that is extremely beneficial to my experiment! This particular thing is: the sunflowers further away from the sweet potato have grown considerably larger than the sunflower closer to the sweet potato! 


BUT. But. The transplanted sunflower from Box 1 (the one that was eaten by a bug) that is now in the round pot, has not shown any signs of growth either. So maybe both are still regrowing their roots and have thus not visibly grown. Oh well...time will tell if the allelochemicals are doing their work!

In Box 2, the sweet potatoes are still looking healthy. Furthermore, one sweet potato (the one in the centre at the bottom) has begun growing leaves! This is significant because it's begun to grow leaves much later than the others.


As said before: in the round pot, the transplanted sunflower (the one that was eaten by a bug) has still not shown any signs of growth.


~ Day 18 ~
BREAKING NEWS!!! In Box 1, the sunflower transplanted from the round pot (the one not eaten by a bug) has visibly grown - but not much at all!

HOWEVER, the plant in the round pot (the one that was eaten by a bug) HAS grown! That means that the allelochemicals must be working, because all the other sunflower plants are now significantly bigger than the sunflower closest to the sweet potato in Box 1!! WHOO!!! In addition, the carrots are looking healthy - if a little sparser than before.


In Box 2, the sweet potatoes are still looking fine. BUT now another sweet potato has started to grow leaves - the last sweet potato plant to do so. So all sweet potatoes are now growing well. :)


In the next bit of breaking news, the transplanted sunflower from Box 1 (the one eaten by a bug) has now grown a new set of leaves above the old ones that were eaten away! All the sunflowers have, by now, sprouted a new set of leaves, and the transplanted sunflower [I will call it that from now on - the other transplanted one, now in Box 1, will the Sunflower 1 now.] has followed this development.


~ Day 20 ~
Finally, to today's observations.

In Box 1, the sunflowers further away from the sweet potato (not Sunflower 1) have grown considerably. The leaves are now larger - mostly longer rather than wider. But Sunflower 1, on the other hand, has grown significantly less. It has still sprouted a new set of leaves, but they are smaller and, more importantly, shorter than the leaves of the rest. YAY! :D 
The carrots are definitely sparser than before...and I'm not quite sure how they can be, but you can see a whole lot more dirt between the stalks of the plant than you could before...

The sweet potatoes are just fine in Box 2. No new developments.

In the round pot, the untouched sunflower (not the transplanted one) has grown just like the rest of them, and is now about the same size as the ones further away from the sweet potato in Box 1. The transplanted sunflower has grown slightly as well. :)
