What the heck are these?!!

Found these little bugs on my squash this morning. What are they?

Veggies, Disease, and Mineral Deficiencies?

Well, it seemed about time for an update, so I thought I'd post some pics of the veggies. For the most part, things seem to be going very well. The squash has been productive and delicious, though the leaves are yellowing, get these splotches on them, and eventually wither and die.
I thought there was a serious mineral deficiency going on with this cucumber, but it turns out that it's some sort of white cucumber hybrid. Park Seed calls it "Cucumber Pearl", and they threw the seeds in with my last order. They taste good.

The peppers seem to be going OK. They were struggling for a while while their roots got long enough to stay in the water, but they seem to be doing well now.
The tomatoes are doing great! There are several large tomatoes on the vine, just waiting to turn red.
So, not knowing anything about minerals, mineral deficiencies, pests, or basically anything about hydroponic gardening, I thought I'd throw these photos out there in case someone who did know something about anything could respond! I've been adding 5ml iron and 30 ml of Potassium weekly, with an occassional blast of Kalkwasser to supplement calcium and help keep the pH up. I guess it's not enough for the squash, but seems to be OK for the other stuff. Again, I don't know.

No tilapia this year

Well, I've given up on the tilapia. No word from Foster Pond and Lake, and another blogger sent me an email advising me that I'd never be able to find large tilapia this late that people would be willing to part with. So, we went to Petsmart and bought 30 goldfish. At $0.28/fish, the price was right! Obviously, we don't plan on eating them, so unfortunately, our system will not be a fully functional aquaponics system - more like a water garden/hydroponic veggie garden. Oh well, maybe next year...

Here are some photos. One thing that seems certain - yellow squash seem to like the set up, and so do tomatoes.

The residents - one koi, one comet, and 30 goldfish

Still no tilapia!!!

Well, it's been at least a month now since I expected to have tilapia in the pond, and we still don't have any. At least now I know why. The nice folks at Foster Lake and Pond Management get their tilapia from a supplier in southern NC. That guy had an equipment failure this spring and moved his tilapia from the nice, protected shelter of his indoor operation into an outdoor pond on his property. That was great until a hungry otter came in and ate ALL of the fish! Of course, the farmer didn't tell Foster Lake and Pond, but tried to find an alternate supply to meet his delivery. He could not, and that screwed FLP, which, in turn, screws us. FLP was trying to find an alternate supplier late last week, but they haven't called, and I'm beginning to wonder if it is even worth it at this point. We're seriously considering just getting some cheap fish - the cheapest we can find - to stock the pond with for the veggies, so at least we'll know how the veggie part of the aquaponics system works. I must say, though, that the veggies seem to be doing OK despite only two fish. Photo of the main bucket is from June 1. We harvested a yellow squash yesterday.

Mid-May Update

I thought I should update how things are going, since it's been about a month. First, we still don't have any tilapia. The word from Foster Lake and Pond Management is that they don't have their tilapia in yet, 'cause of the colder weather this spring. They were confident that they would be in soon, and they'll be larger than usual, so there should still be enough time to grow them out to plate size before it gets too cold this spring.

Sometime soon after my April post, we had a torrential rain that eroded out the mound that the upper bog was sitting on, 'causing it to slant. It was not level enough to use, so I had to empty out all the gravel and re-level. I decided at that point to just run the outflow directly into the pipe that spills back into the pond instead of filtering it through the second bog. Everything's working great now, but I lost all my plants in the upper bog.

As you can see from the photos below, though, we bought some tomato, pepper, and squash seedlings, and they seem to be doing OK. Note also that the lower bog lettuce is coming in, and some tomatoes from seed are also coming in. I think that they aren't getting quite enough nutrients from the two fish that are living in the pond (oh yeah, one of the koi died mysteriously. he was always a little sickly from day 1).

soybeans, lettuce, small tomatoes are original. squash, large tomatoes from seedling

what you don't see clearly here in the upper bog are the little cucumber seedlings coming up from an extra packet of cucumber seeds we had in the house. there are some little pepper seedlings hanging on, as well.

trying their hardest to poop enough for all the plants!

The plants in the pond are doing amazingly well. Considering that they were dormant and kind of runty looking, they have truly gone through a miraculous transformation. Below, you can see what one month meant to a bog arum. And, we were fortunate enough to get one of our iris versicolor's to bloom. For a larger version of that photo, click here.


Next update after the tilapia go in. It will be interesting to see what happens, as the pond system is in a nice equilibrium right now. The water is crystal clear. Many of the plants are yellowing, so I believe they need more nutrients (and soon!), but for now, everything appears to be surviving. I anticipate that once the fish are in, the yellowing will stop and the growing will increase. Stay tuned!

Pond costs

I thought I would share just how much this pond cost, not including time and labor or electricity for running the pond pump (~100 watts/24 hours a day), just so you can get an idea of the amount of effort and money required for set up. I'll also estimate yearly operating costs.

- Landscaping (plants, dirt, etc.): $1756 (48% of the cost)
*$1366 of that was for rocks/gravel - all delivered
- Pond/bog construction (liner, skimmer, plumbing, electrical, bog tubs, caulk, etc.): $1353 (37% of the cost)
- Pumps/filters: $276 (7% of the cost)
*I bought a backup pump and replacement filters, in addition to current one)
- Fish, fish food, meters, nutrient additives: $307 (8% of the cost)

Grand total: $3692

Annually, you'll need to buy new fish, fish food, nutrients, some plumbing/caulk for leak fixes, filters. I imagine that will be no more than $500, but I'll keep track and document after one year has passed.

Aquaponics Happening!

Well, everything is finally done! The only thing that remains is to pick up my tilapia the first week of May. The pond is running, the bogs are running, the native plant section is planted and mulched, and the plants in the pond seem to be getting used to their new home. The two garden bogs are already showing signs of seedlings, less than one week after putting the seeds in! The native plant bog is looking great, and one of the dwarf crested irises is blooming! The only species that I'd like to add are some pitcher plants, but the only ones that I can find so far (Lowe's) aren't the native varieties found in NC.

Species List:
In the pond:
- iris versicolor (blue water iris)
- pellandra virginica (bog arum)
- lubellia syphilitica (great blue lobellia)
- sauronus sp. (lizard's tail)
- pontederia cordata (pickerel rush)
- acorus calamus (sweet flag)
- alisma subcordata (water plantain)

In the pond bog:
- chamaelirium luterm (fairywand)
- lobellia cardinalis (cardinal flower)
- hydrophyllum virginiaum (eastern waterleaf)
- iris cristata (dwarf crested iris)
- iris bericaulis (zigzag iris)

In the native perennial garden surrounding the pond:
- oenothera fruticosa (southern sundrops)
- callicarpa americana (american beauty berry)
- peristemon smalli (small's beardstongue)
- symphotichum oblongifolium (eastern aromatic aster)
- muhlenbergia capillaris (hairgrass)
- coreopsis triptens (tall tickseed)
- silene virginica (fire-pink)
- helianthus augustifolius (swamp sunflower)
- rudbeckia fulgida (orange coneflower)
