Early Season Update

First, an update on my sand-based system. I noticed today that the water was collecting on the surface of the sand more than usual. Turns out that an algal mat is forming, and as a result, the water was having a hard time permeating into the sand. This is to be expected, and it's not a big deal. In fact, I think the algae will play an important role in the nutrient cycle for the plants I'm trying to grow. Problem was easily remedied by poking a few holes in the sand using a piece of 1/2" PVC pipe.  I imagine I'll have to do that regularly. Luckily, I planned ahead for something like this, and created channels in the sand around the outside of the grow beds for the water to move through. Since I don't plan on planting anything in these channels, I'm not interfering at all with any of my plants by poking holes into the sand.

My pond-based system is cranking along nicely. I'm in full swing in terms of spring veggies. See photos below. I'm particularly excited about the strawberries. They look fantastic, and there look to be a record number of berries on the way. I thought of a new term today for my system: "aquapondics". You heard it here first!

Spring Veggies Coming Along Nicely!

In my established system, things are looking really good. I've already harvested a ton of arugula that we've used in salads and also made a nice pesto out of. There's more arugula on the way, too. Spinach is looking nice and ready for harvest. More salad for me and spinach quesadillas for my son. Some of the cilantro grew up nicely, and that ended up in some of my famous salsa (thank you Giemzales!) The strawberries are looking fantastic, and there are plenty of flowers blooming.

The broccoli seeds have germinated well, as have the broccolini, so things are looking up. With one batch of arugula out of the way, I have some space for tomatoes. I've already purchased 4 seedlings, but the weather's not cooperating. It's been over 80 the past two days, but it's supposed to drop to near 32 tonight and not get above 60 for the next 5 days. So, I'll wait a week to stick them in the grow bed.

Some of the worms that I put in there last year survived the winter. I'm not sure how they managed that, since the grow beds were flooding continuously. Hardy little suckers!

Pond plants seem to be taking off even earlier this year than normal.

Update on Pond System

Well, after that one sticky week where everything had frozen into a solid block of ice, everything has been working perfectly. I did not detect any new leaks or pipe cracks or any other negative consequences of the super cold. My plants actually survived for the most part, which is amazing, and a testament to the resilience and vigor of plant life itself. I did lose some arugula, but the plants that survived are doing quite well.

I've added more seeds, and I'm hoping the warm conditions will last long enough to let them germinate and form a root to tap into the lower levels of the grow beds where the water is.

Looking forward to April, when things will get going in full force!

No trout, but we got catfish

I couldn't find a trout supplier this year. Bummer. I'm sure I could have found one way out near Tennessee and driven 4 hours+, but it wasn't worth it. Instead, I found out about Southeast Pond Stocking (http://www.seponds.com/) and picked up 20 channel catfish. They happened to be making a delivery round, and one of their stops was in Siler City, about 15 minutes from my house.

I think the catfish are used to the good life of coastal living and warmer temperatures, though! They probably were in for quite a shock when they arrived in my pond, and water temps were about 40 degrees. Temps. are probably lower now, as we're in the middle of a serious cold spell, with day time temps in the mid 30's and night time temps below 20 degrees (fahrenheit).

Hopefully, they'll pull through!

The arugula in one of the grow beds is doing really well, which the spinach in one of the other grow beds is doing pretty well. The others are still very small and fragile looking. Not sure what's going on, but at this point, there's not much that I can do. The mini-greenhouses are doing OK. I think the larger issue is that the trees around my property are getting tall enough that they're starting to shade the growing space for more hours of the day. Short of hiring some tree trimmers to come in and cut off the top third of the trees, there's not much I can (or will) do.

Mini-greenhouses or coldframes - not sure what to call them

First post in a while. I've been so busy with work and travel that I haven't had any time to spend in the garden. Maybe that's why it's been so sucky lately??

Anyway...

Dedicated readers (if there are any) may remember that last year, I put together a makeshift, greenhouse-like structure out of old fencing, some fenceposts, and some plastic tarps. Rather than go down that same path this year, I decided to build a mini-greenhouse for each of my grow tubs.

 First, I built a wooden frame around the grow bed. Not as easy as it sounds, even though all the grow beds are the same product. They each seem to sag in a different way, so each of the frames had slightly different dimensions and different heights.

 

Next, I created a PVC greenhouse using mostly existing 1/2" PVC that I had from other experiments uses. I bought special 45 degree elbows and special 3-way fittings for the bottom corners from a greenhouse supply store.

  

Once the PVC frames were done, I used my old plastic that I used last year. I basically rolled the frame in the plastic, then used plastic clips to hold the clear/opaque plastic to the PVC frame. Each greenhouse has 2 little chimneys that I'm hoping will help it from getting too hot in there. Though the plastic drapes down the sides, it's certainly not air tight, so there should be some air flow, even when the sides are fully down.

 

 Here's a view through all 3 greenhouses. I rolled up the sides to keep air moving through there. I probably will keep it rolled up until it gets closer to 25 degrees at night. 

The cilantro, arugula, and spinach that I've planted, along with the tub full of strawberry plants, proved last year that they can handle the cold. The greenhouses should help warm things up during the day nicely, and they'll keep the frost off of the plants at night. Another side benefit is that they keep the leaves from landing on the grow beds! This time of year, it's a daily chore picking the leaves out.

I put in another order for rainbow trout this year. It went so well last year, I figured we'd do it again this year!

Peanuts + Fall update

Well, I pulled up my peanut plants today. I didn't really know if it was the right time or not, but I figure it won't be too much longer before we have our first frost, and I wanted to have them up before then. In any case, we have peanuts! I'm gonna dry them out for a few weeks, so I'll report back on how they taste.

In other news, I have a bunch of green tomatoes on the vine. They are still very green, and I keep hoping that one morning, I'll wake up and they'll start turning. Time is running out!


The broccoli is looking good. I've been battling some caterpillars that really eat up the leaves like crazy. They hit them last spring, as well. I've seen fewer and fewer recently, so maybe I'm winning the war. Or, maybe they are regrouping for another assault.

The bok choi is looking good, but the spinach is kind of hurting. When it sprouted, it looked like grass it was so thick together. I suspect that maybe it was TOO thick, and they choked each other out. Hopefully the strong will survive!


Finally, I'm gonna get some rainbow trout in the pond in November. I hope to grow some cilantro or something in the buckets during this time, but I'm not sure anything will grow with the water as cold as it will be. If all else fails, I'll empty the pond and fill it up periodically to keep the nutrients down. Apparently, the trout don't like water over 70 degrees F, so it may be a struggle to fatten them up enough to eat by next spring.
