Albion strawberry crowns in a Farm 12 and Kratky: successful fruit with intensive pH management
Grow log by lynnee · Original thread
What you can learnOne of the strongest experimental diaries in the set, documenting a controlled Farm-versus-Kratky comparison and the close relationship among pH, calcium uptake, root health, and strawberry quality.
Useful practices
- weekly complete solution changes
- daily pH monitoring
- CalMag supplementation
- electric-toothbrush pollination
- runner removal
- comparison with a Kratky control
Problems encountered
- rapid pH decline
- calcium-deficiency leaf-tip burn
- potassium-deficiency leaf edges
- black roots and reservoir sediment
- fruit flies or gnats
- high maintenance burden
*The days were calculated automatically and approximately.
I am glad they recovered, lynnee. Prima donnas, indeed!
They have recovered nicely. I wonder if all the sediment is from the soil/dirt they were in prior to you getting them?
Some of it was that, I think. I rinsed the roots when I planted the crowns, but it's hard to get all the dirt out. Some of the sediment was probably from nutrients left behind when I siphoned the bowl. And some was probably from deteriorating old roots that came with the crowns.
Day 114 (Ended 6/16/22) Yesterday I ended the Albion strawberries, because I was tired of (1) testing the pH all the time, (2) doing complete R&Rs (including washing the bowl) every week, and (3) watching the fruit flies or gnats fly up whenever I touched the leaves.Turns out it was a good idea, because nearly all of the roots were black again. This happened after I did a siphon-only refill the last time and failed to adjust the pH every day.I won't try to grow strawberries in a Farm again, because they need so much daily attention! It's much easier to change the water completely if they're in a Bounty, and the plants don't need much vertical space. The roots keep to smallish root balls, too.The Albions grown from Burpee crowns purchased and planted at the very beginning of the growing season produced quite a few delicious strawberries. They probably would have done even better if I had monitored the pH and the roots from the start.The strawberries started from sale-priced crowns purchased at the end of the growing season have produced lots of tall leaves, but few strawberries.
That was an interesting summary, lynnee. I agree, that's a lot of work for an Aerogarden!
I too agree, your write up was good and can see how much you put into them. I am happy you were able to grow and eat them and enjoy too!
This is amazing work! Sorry I took nearly a year off after getting discouraged. Your instrumented approach reveals a lot of insight as to why I kept seeing unhealthy roots during my first attempt.Rinsing on a weekly basis is not feasible. Too much work indeed! I am going to give growing berries one more try and will post pictures in a few days. But if it takes a weekly rinse to keep things going I'll end the grow and move them outside. Thank you for the hard work and excellent documentation!
agfarm, don't plant a crown in every pod opening, and keep the pH at a comfortable level for strawberries, and you should do okay!
Update #17
The misshapen strawberry looks eerie! And I do see those rubies hiding in the dark. I used to collect wild strawberries. They did the same thing -- flowers high above the plant, with the fruit hidden underneath. I wonder if it is an adaptation to protect the fruit until it is ripe? Then the critters scatter the seeds.
Wow, all the fruit/seeds are on the bottom. That is odd. But I too see some fruit in the darkness.
It could well be a means of protecting the fruit. My grandmother, a farmer's wife, was always complaining, "The birds got most of my strawberries this year."

I am so happy these are thriving.
Thanks! I'm still amazed, because my AG strawberry crowns did so poorly. That made me think that "grow strawberries in your Aerogarden" was mostly advertising hype. I have another dozen crowns from the same Burpee shipment in the garage. Before long I'll take the Zebras out of the Farm Plus 24, and plant the crowns if they still look okay. (The Zebras really belong in a Farm XL, because they're indeterminates that grow fairly tall.)I want to find out whether strawberries (Albions, anyway) will do well from the outset if you do nothing other than weekly R&Rs with close pH monitoring (6.2-7.0).
lynnee, your gorgeous strawberries continue to amaze me!

The roots look good to me. Don't mess with success. Keep on doing what you are doing!
I would continue with what you are doing as you are getting some wonderful strawberries.
Update #14
Beautiful, beautiful photos! lynnee, are you using AG nutrients? I am puzzled by your pH fluctuations. Do you see that only in your strawberry gardens?
My mouth is watering for strawberries now.
Thanks! Yes, I'm using AG nutrients (24ml per weekly R&R) plus CalMag (10ml per R&R). It's only with mature, fruiting strawberries that I have extreme pH changes.The mature Mini Munch cuke sometimes drifts toward acid, but it hasn't needed pH adjustments between R&Rs since I added the Aerovoir. It consumes a lot of nutrients, according to the TDS readings that may go to 200 or less between biweekly R&Rs.Strawberries need a lot of calcium when they're growing and fruiting, which accounts for the need to keep the pH adjusted. Why the water gets acidic even with weekly R&Rs is a total mystery to me. Maybe it's because they are consuming the nutrients so quickly?This excerpt from an article at Strawberryplants.org stresses the need to maintain a healthy pH level. I think that you can do this adequately with weekly R&Rs with only AG nutrients, but strawberries do seem to need extra attention once they're growing and blooming. FWIW, I am still shaking my head at the strawberry plant in the Kratky. I wouldn't have believed it possible to grow harvestable, tasty strawberries that way! Now I'm really interested in Kratky culture, because it uses so much less water than soil culture. California's drought is getting pretty serious.
Once again, you have given us fantastic insights on strawberry nutrition, also widely applicable to other plants. Thank you, lynnee. it also occured to me that calcium raises pH, so if your strawberries are using lots of it, that could also contribute to the increasing acidity, I would think. As for Kratky, it's phenomenal, even on large scale projects. Here are a couple of mind boggling videos for you from vloggers I like: Peter Stanley - Changing out 45 gallon Kratky trash can nutrients Matt Garver -- Giant Kratky squash and cucumbers

Your strawberry experiment is an impressive success, lynnee. I love Kratky, and used to do a lot of it. Space and light are my limitations. Still, I am surprised that the Kratky strawberry was bigger and tasted best.
Kratky definitely grows on you! I can't believe that the strawberry crown survived, let alone that it is producing fruit. It even has unhealthy-looking roots. It has received extra R&Rs, because I wasn't sure about how much AG nutrient to add to 1 pint of water. It seems to be happy with 1.5 ml, along with weekly/biweekly rinses.
They look juicy sweet

That one ripened really fast. I also spy a few others in there.
lynnee, it is HUGE! And so beautiful, it almost doesn't look real!
When I ordered the crowns, I thought they were dwarfs. Now we know that you can grow Albions, which are not dwarfs, in an Aerogarden.

Wow! So healthy and beautiful! My guess is that Burpee's advice is more for soil grown plants, and AG's is more for hydroponics.
Look at that strawberry ripening. Beautiful.
Amazing progress!! Your leaves look excellent and I like the size of those berries.I want to offer advice on runners but full disclosure...both my strawberry attempts are not doing well. Having said that, I have been trimming away runners.
Update #10
I am so happy they are not miniatures! More bites for the effort!
That looks fabulous!

I am so excited about your developing strawberries, lynnee! And your bottom photo highlights the unusual veining pattern of the leaves in stunning detail. I had never paid attention to that before seeing your photo.
You have a sharp eye, Sher! That's why your photos of little wildflowers are so enjoyable.
So many berries!!! Very exciting!! Do you trim your plants at all? Mine are DENSE and I'm starting to think maybe I should, I haven't done any cutting on them since the initial thinning
maskedsonnet, When I'm learning to grow something, I let the plant do what it wants until intervention is clearly needed. So I haven't done anything besides (1) pollinate every blossom, repeating every day until the petals fall off, (2) remove new leaf sets with blackened leaf tips, (3) remove runners, and (4) do weekly R&Rs.Mine were started from Burpee New Albion crowns, not from seeds like yours. Much to my surprise, the single Kratky crown has three strawberries developing.I think that Burpee crowns must be particularly vigorous!

lynnee , I know absolutely NOTHING about growing strawberries. But sometimes brown growing tips are because the plant is growing faster than it can uptake adequate calcium.Sometimes a fan will make a plant respire faster so it draws up enough calcium. Other times a bit of calmag can help.I have no idea if that applies to your strawberries. Or the reservoir could be so acidic that that is what is affecting the uptake of calcium. Here's a pH chart that might help. (And I bet Shawn already has it posted, but I forgot to check.)
Some of the older leaves are brown at part of the edges, Sher , so it could well be a calcium issue. I'll add 2ml CalMag+ now.Not that I'm knowledgeable about the science like you are!
Aw, lynnee, I am not that knowledgeable. I just like reading geek hydro stuff!
Yup, it is posted Sher LOL... In the Nutrients and Supplements Section
Thanks. I realized it probably was.I need to go through that board and familiarize myself with everything it contains. It is a gold mine!
No you don't I just refer to where everyone should look LOL
It IS a gold mine, Shawn! I need to get in the habit of looking there before I start Googling.

They look so good.
Someday do a search for Rick, who tried repeatedly, unsuccessfully, to grow strawberries in a Harvest. Your garden would have looked like heaven to him. (I think he must has passed away before ever achieving success.)
Your progress looks great! And excellent write up. It is very clear and has all the key details starting at post 1. I too saw that note about removing flowers until the crowns have grown some more. I feel like that is part of how my seascapes started to decline (when I decided not to cut off flower trusses). It is just too painful to kill off those beautiful flower trusses. Maybe try on a select couple to see how they compare?
agfarm, that's a good suggestion, and I'll experiment. Did you remove the flowers on the pineberries?
That's a great question/point. I did not cut any flowers on the pineberries. At first, the pineberries dragged in progress when compared to the seascapes. The pineberry fruit is growing very very slowly. What's confusing is only half the pineberries are flowering. All pineberries are making runners.Seascapes are not making any runners...interesting.
Also, at the beginning, I trimmed the roots of my seascapes to about 6 inches. I see you did not, instead you modified the pods.I think that's a key point to your early success. My seascapes took time to recover their roots after I cut them. Roots are arguably more important than leaves.
Not trimming the roots may have allowed the crowns to grow faster. I didn't even think of trimming the roots, because I didn't have the AG instructions in front of me when I did the planting! I love growing new types of fruits and veggies for the first time. Figuring out what they need to flourish and to taste good is more fun than actually eating the final produce.
Oh, lynnee ! My deepest sympathies!You have an utterly incurable case of Aerogarden addiction!

lynnee , I used to use those lights a lot for Kratky -- some on the stand and some suspended in a closet when the plants got too tall. They worked great! Your little strawberry should love it. And your strawberry plants all look amazing!

Good luck!! Strawberries are the best
I have seen people really struggle with strawberry crowns. I think your setting yours way up high might be the magic solution. Crossing my fingers that they are a stunning success! DcKpvN
The height can be adjusted, I think, if it looks like the right thing to do. I have another dozen of these plants, so can try again if this batch fails quickly. I don't know how long bare root plants remain viable.These crowns seem much healthier than the ones that AG used to sell. The AG crowns were much smaller, and very dried out. A couple of them were actually DOA.Anyway, agfarm's and maskedsonnet's great strawberry projects here are what inspired my second try at strawberries from crowns..
Following and wishing you great success with them.
