~ Days 37 - 41 ~

~ Day 37 ~
Today the plants looked pretty much the same as in the last post - in Box 1, the sunflower in the bottom left-hand corner is still a whole lot bigger than Sunflower 1. The carrots and watercress look about the same as before - still green, no significant leaf loss or anything like that.
In Box 2, the sweet potatoes look like they have grown. :)


In the smaller pot, the sunflowers look fine, too. The one that was transplanted from Box 1 (ages ago) has grown another set of leaves, like the rest. It looks much healthier than before.


~ Day 39 ~ 
The plants look the same today, again. I'm sorry that I can't describe it more, but there seems to have been not much visible change...


~ Day 41 ~ 
The sweet potato in Box 1 has grown taller! The sunflower in the bottom left-hand corner is now positively gigantic, as well! Sunflower 1 looks tiny, in proportion. The sunflower in the top left-hand corner has begun to grow small leaves - it's beginning to recover from the "pruning" we gave it, I suppose. 


The sweet potatoes in Box 2 look fine as well. 


The sunflowers in the smaller pot are beginning to grow longer leaves. :)


~ Day 34 ~

Sorry that this is a day late - I took the photos on the right day, I just forgot to post them.

In Box 1, the sunflower in the bottom right hand corner has undergone a growth spurt or something! It's been two days, and yet the leaves seem to have grown almost explosively. It's freaky. Why can't I grow like that?? 

Furthermore, the sweet potato in Box 1 looks as if it has grown a taller, too. The carrots look like they're slowly regaining their leaves, and the watercress looks pretty much the same as it did two days ago. Sunflower 1 looks about the same as well, which is worrying compared to the "growth spurt" the other sunflowers have gone through. I mean, the sunflowers in the smaller pot also seem to have grown explosively - but Sunflower 1 has not. YAY!!!! Sunflower 1's growth is being inhibited by allelochemicals! I will never get tired of exclaiming that. At least while the SRP is on. 

Lastly, the sweet potatoes in Box 2 look fine.

~ Day 32 ~

Okay! Today I looked at the sunflowers in Box 1 again, and the one on the bottom left hand corner is amazingly big now! It seems to have sprouted yet another set of leaves - bringing the total to more than 4 sets of leaves. Whoa. I never knew sunflowers grew this many leaves...

Anyway, Sunflower 1 (nearest to the sweet potato) is also at the same stage in growth as the other sunflowers, except overall it's just smaller. Yay! The allelochemicals are still effective :)
Ah - the other sunflower, that had toppled over due to insects eating its stem, (in the top right hand corner) has lost all it's leaves because I "pruned" it - the leaves from before were obviously dying and I cut them off. They weren't going to do anything but hinder the regrowth of the plant. So yeah. The carrots look like they're regaining their leaves (yay!) and the watercress looks pretty similar to when it did during my last post. 

The sweet potatoes in Box 2 are fine, as usual. But today they looked taller than before - some visible growth! So now I know they are still growing healthily.

The sunflowers in the small pot are also growing along with the sunflowers in Box 1. 

~ Day 30 ~

Whoo! One month since I started this whole project. Well, it's also today that I planted my 3rd type of test plant (besides the sweet potato) in Box 1. I know it seems extremely late and stupid and unfair on the last plant's part as it has had the least time to grow around the sweet potato, but the plant I got had been growing for at least a month before I planted it - look at the photos! If they show up, that is. I really need to get to Ms Zhang about that.

Anyway, as stated before, I planted my third test plant. It was going to be cauliflower (remember from previous posts?), but the Flower Power shop didn't have any already-grown plants and so I gave up on that. Interesting fact: The last cauliflower plant was apparently bought merely hours  before I came in to the plant shop, and the plant had apparently been a tall, healthy, yummy-looking cauliflower. Damn. 

Seems like the world is working against me, huh? So I decided to plant some watercress because they're also sensitive to allelochemicals, if I mentioned in posts from last month or so. But on to the planting part - the watercress I used was a herb of the "culinary" style...that's what it said on the tag. I'm not sure of the significance of that, but what the hey. Now you know. :)

I planted it on the right side of the sweet potato - the empty space from before, you know?
And here's a photo, because this time I actually uploaded it and it took way long. =="


Okay. Then I sprayed the sunflowers and carrots in Box 1 and in the smaller pot - because those are the ones that have been eaten by insects - with "Sharp Shooter Natural Pyrethrum Insect Spray". It's the insecticide that the man in Flower Power recommended to me. So yeah. The insect spray is an extract from the pyrethrum daisy, so I suppose it shouldn't affect the plants too badly. I'm supposed to spray the plants once a week until it appears that the insects aren't eating the plants any more.

Oh yeah - I also discovered that the sunflower in the left-hand top corner had been "pushed over" by an insect eating at its stem. The insect ate almost half-way through the stem, and the flower subsequently fell over. Stupid insects. So that's why I sprayed the insecticide on it.

The sweet potatoes in Box 2 look fine - here's an uploaded photo of it:
 

There haven't been any major developments in their growth lately, though.

The sunflowers in the small pot are also fine - as you can see here:

~ Day 27 ~

Everything's going well in Box 2, as usual. No photos, because as far as I have seen, the photos aren't turning up in my posts. I will ask Ms Zhang about that as soon as possible. Which won't be long, because school's starting up again soon. :'(

But in Box 1, disturbing things are happening to my sunflowers. One of them (not Sunflower 1, these are further away from the sweet potato) looks like it has been pushed over - and physically, which means not by some sort of aggro allelochemical. So I am, naturally, worried. I'm not sure if my sunflower will recover...but I definitely hope so. Sunflower 1 is still really quite small compared to the other sunflowers, which is good. The carrots don't appear to have been eaten further - I hope they will recover from that too. 

But in the small pot, the extra sunflower - its lower set of leaves have begun to yellow. Just like Sunflower 1. I wonder what this means - that the allelochemicals don't make leaves turn yellow (in particular), but it's just the weather or something? Because the other sunflower in Box 1 (that isn't Sunflower 1, and also isn't physically pushed over) has perfectly green lower leaves. So this is more than slightly strange.

~ Day 25 ~

Ah. First of all, my climate graph:


















Okay. Now on to observations.

In Box 2, all the sweet potatoes are growing quite well. I suppose that it is reasonable to conclude that, by now, maybe sweet potatoes are immune to their own allelochemicals? It would make a lot of sense. 


In the smaller pot, the sunflowers have continued growing.


But in Box 1, Sunflower 1 is beginning to turn yellow! Yayyyyyy!!!!! The lower leaves of the plant are turning noticeably yellow - I suppose the allelochemicals are finally doing their work in a very visible way. :) If you can see the photo, it is of the yellowing bottom leaves.

 

If you can see it. All my photos are being dodgy!


Also, the carrot plant has stopped being eaten so badly - it looks like it's recovering. Perhaps there will be no need for insecticide. However, the bottom leaves are also turning slightly yellow - well, paling in comparison to the leaves and upper parts of the plant. Yay!!

~ Day 23 ~

It's Monday again. :(

Anyway, everything's going fine in Box 2 and the small pot. But in Box 1, it appears that something has been eating my carrot plant! That's why it appeared "more sparse" than before - the leaves are being eaten away!

This is really bad. I want to get some insecticide, but maybe it will affect my experiment! Too much to consider...but truthfully, insecticide is formulated to not affect the plant, right? And to only affect the insects? Because the leaves are getting eaten away pretty aggressively. Almost half the leaves are gone already, and there's basically no remnants of the leaves left on top of the soil. Although the insecticide may affect the experiment, at this rate there will be no more carrot plant (above soil...who knows, maybe even under the soil too!) to observe. 

Oh well. Nothing I can do right now. 

Method

Okay, this is my method that we need for the next blog marking.

Materials and Equipment:
~ Two styrofoam boxes - approximately the same size: 
~ One smaller pot (size doesn't matter, but it has to be large enough to fit a few extra sunflowers)
~ Sunflower seeds
~ Carrots (the ones I used were already growing in their own potting mix; ready-to-plant)
~ Cauliflower seeds
~ One sack of potting mix
~ At least one sweet potato that is already growing tubers - you will need at least 8 tubers
~ Camera
~ Labels


Method:
1. Cut eight tubers off the sweet potato, leaving a small area of potato skin around the tuber. 
2. Label one of the styrofoam boxes: "Box 1" and the other: "Box 2".
3. Fill the two styrofoam boxes and the smaller pot with potting mix. 
4. Plant one potato tuber in the centre of Box 1.
5. Plant the rest of the tubers in Box 2, making sure that they are evenly spaced away from each other.
6. Plant three sunflowers in Box 1 - two in the left-most corners of the Box, and one just beneath the sweet potato tuber.
7. Plant the carrots in Box 1 - above the sweet potato tuber.
8. Plant three cauliflowers in Box 1 - two in the right-most corners of the Box, and one to the right of the sweet potato tuber.
9. Plant a few extra sunflowers, cauliflowers and carrots in the remaining small pot - as many as you can fit. 
10. Place the Boxes and the small pot in a place where they will receive equal sunlight.
11. Take a photo of each Box and the smaller pot.
12. Make observations and take photos of each Box and the smaller pot every Monday, Wednesday and Friday for two and a half months.
13. Record your observations in the Results section.
14. Pack up any equipment - extra plant seeds, camera, labels, etc.


So there we go! :)


Yes, I am aware that I still don't have any cauliflowers. =="
I'M SORRY. I'm planting them today as part of my "plant a new plant every 10 days" - eg: I planted the carrots at Day 10, and today's Day 20. I realise that this is really bad organisation, but I have to plant the cauliflowers someday and this is the earliest I could. Sigh.


Also, the pictures I try to post aren't showing. Why???

~ 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. :)

WAIT.

I am still aware that I am late again in my posts.

SORRY! It's just that I've been on holiday for the weekend, and am going on another holiday tomorrow.

So no time to write up my observations, although I have been taking them at appropriate times.

Expect a catch-up post, including all photos and etc., to come out in approximately two days.

Goodnight!

~ Day 11 ~

Yes, I am aware that I am a day late in writing up these observations. Sorry.

Yesterday, I looked at my plants in Box A, and the sunflower nearest the sweet potato was totally destroyed - but perhaps, probably, by a bug. There were holes in the leaves - which allelochemicals probably did not cause - and it looked really dead.

However, it was also shorter in height and the stem was narrower in width than the other sunflowers - this was probably caused by the allelochemicals. :)

But seeing as the plant was almost dead, and maybe not totally by the allelochemicals' doing, I uprooted the sunflower and replaced it with one of my extra sunflowers that I grew in the small round pot. The new sunflower is smaller than the other sunflowers in Box A, which is strange because Box A contains a sweet potato, whereas the small round pot only contains sunflowers. But anyway, it is the sunflowers in the pot that have not been affected by allelochemicals yet, so I will just have to use one of them to keep my experiment fair.

Furthermore, I planted my carrots! As you will see in the following photos, the carrots are about the same distance from the sweet potato as the "new" sunflower [from previous paragraph] is. Yay!

Now I just need some cauliflower...

Anyway. Uhm, the photos are not showing up properly. So I'll just wait and get some advice on that. THERE WILL EVENTUALLY BE PHOTOS!


And I won't be here tomorrow - Friday - because I'm going camping. So I'll just take photos & observations today.


See you next Monday!
