Could just be radish that bolted ("bolting" just meaning putting out flower stalks). If they got significant heat then it's not impossible they just bolted early. Maybe if they weren't bred carefully you could have got some weird radishes too.

Were they the "winter" (aka daikon, mu, watermelon) radishes, or "spring" radishes? If they're winter varieties (the best kind to make kimchi out of) you're probably too early even. Radishes quite like cooler weather, so you'll typically plan backwards from the expected last frost date to figure out planting time. So if your variety takes 60 days then find when 60 days before the average last frost is and plant them then, which may be late summer. You'll want to harvest them around the frost time.

For spring radishes you can also do a quick crop as it gets colder. They typically will take much less time to develop and are smaller. You can do the same thing, just wait for early fall-ish and throw them in the ground.

I just looked at the order listing and it does list them as autumn seeds. Ooops. Live and learn.

Our season has been really weird. When I planted them in early February, we had a mix of 30-75 degree days and it seems like our rainy season is about a month later than usual.

Finally finished my wicking planter. We're hitting winter here so it's not getting a ton of sun at the moment, going to put a bunch of lettuces, radishes, and Asian greens in and see if anything takes. In summer is when it should be really useful, will get a few hours of morning sun in summer, then be shaded by the house in the afternoon.

By the evening, I had one sad solitary corn seedling left

And yeah, they're basically just getting cutoff at ground level so this checks out

And while I was planting the beds I had noted how many pill bugs were hanging out in there, but maybe they weren't pill bugs at all

The bastards got my last corn seedling today

And pulled out a radish seedling, only to find there was no kernel underneath

So I'm back to thinking it's grackles

So remember a while ago when I said that patience is the hardest thing to learn in gardening? I did this the first year I started tomatoes too. And then a little bit again the second year.

They are probably a bit small, and when you start hardening them off, the plants stop growing for a bit while they adjust to new weather, wind, and temperatures. They'll also probably not grow much for another week because you've just transplanted them and they're still probably adjusting to being outdoors.


Buy, you were spot on. I don't think any of them have done anything in a week, but at least only 1 of them died.

What gets me, though, is the rest of them that were still in the starter seedling trays have been outside this whole time and have still done nothing. I knew they'd stall for a bit when hardening, but I started that days before I did the transplants, yet still nothing. Maybe they got a little taller/leggier, but that's it.

I did move a couple into larger containers to see if that helps, but, like before, almost NO root systems. Just basically one long root that goes into the bottom tray where I bottom-water, very few "side" roots so it takes almost none of the potting soil with it when I take it out. None of the ones I moved into larger containers have died, though it's only been a few days. Considering we've had over 90 degree heat the past couple days, that's impressive they're still alive.

But is there something I should be doing to encourage a little more lateral root growth? Maybe stop bottom watering and water from thew top?

But for some insurance, I did buy 5 starter from a local plant buy/swap group on FB that are MUCH further along than mine. One of which is even the same variety as one of the ones I am trying to grow, the other 4 are sort of random ones, but I tried to get a mix of cherry/grape, medium sized for maybe canning, and thern a big fat one for slices on sandwiches and such.

The usual advice is to not pot stuff up to a larger size until the roots fill the current container, and in my experience that is good advice. Plants just seem to like to be a little crowded or something, and it seems to help them grow denser root networks that then really spring to life when they get more space in the ground or a larger container.

Are you fertilizing at all? Something like half strength liquid MiracleGro is good for seedlings, and if they have a few real leaves you can probably push them a little with full strength.

I’m only right because I’ve made a bunch of mistakes trying to do it myself. The best thing to do is plan to start the seeds a month earlier next year in better conditions.

Bottom watering is good and they’ll send down that tap root before filling out the rest of the soil. It just takes time at about 70 degrees with enough light (I set for 16h) for it to do it efficiently. Adding some watered down fertilizer is a good thing to promote better growth too. Starting mixes don’t normally have any nutrients, unless they’ve started adding it. I have fertilizer that I use for hydroponics normally that has a good balance I like, so I’ll use that in my watering on an infrequent basis.

And I won’t lie, I’ve definitely bought backups before. It’s a great solution. Greatest trick out there.

Hi gardening thread! I bought/planted some plants from a local nursery It was 80 the last couple of days but it looks like we're going to hit a couple of days with lows in the mid-40s early next week. Do I need to be concerned? I have kale, cauliflower, tomatoes, zucchini and sweet peppers, fwiw.

The plants I started from seeds a few weeks ago were doing great in my laundry/furnace room were doing great the first week, then just stalled out, and then when I began putting them outside for a little bit each day to try to harden them off they all started dying and it looks like the last few that I had alive, that I planted on Tuesday, are all going that way too. About all I have left are some tomato seedlings that are looking iffy. :(

Something is wrong with my pepper plants. I have 10 peppers and this discoloration/shriveling is very noticeable on 3 of them - two habaneros and one "orange sun" bell pepper.

I've only noticed it since they've moved outside to the roof. They were grown from seed inside from mid-February to about two-three weeks ago, then I hardened them off for like 5 days (probably too rapid?) before moving them to the roof as seen in the photos. I'm in Brooklyn, so zone 7b. Nighttime temps have mostly been above 60 since they moved out, except one night when it was in the low 50s. They get full sun from approx. 8am to 3pm.

Also worth noting: they are right next to a vent fan for a restaurant, which is pretty loud. I put them there because it's the sunniest bit of the roof and also slightly sheltered from wind compared to the rest of the roof, but maybe the sound/vibration is bad for them? (I'm sure there are plenty of other explanations but it seemed worth mentioning.)

Up ta somethin'


I think I'm just going to have to give up on tomatoes at this house. The only sunny spot suitable for a vegetable garden is right by the back fence and the people behind me have a bunch of native sunflowers on that fence line. The sunflowers act as fantastic breeding habitats for the spider mites and a small breeze brings them right over into my garden just completely wrecking the tomatoes.

Three years ago I lived a few streets over and this was the sort of harvest I was getting off of three plants (one black cherry, two black Krim):



We couldn't eat them fast enough!

This year I have 11 plants (three black krim, six San Marzano, and two black cherry) and I've gotten two cherry tomatoes and a small black krim. Spraying them off daily is only delaying the decline and anyway the plants don't like being that wet all the time. The San Marzano have a good bit of green fruit on them but they aren't ripening quickly and we're entering the heat of summer where even stuff on healthy plants is going to have a very hard time ripening.

Maybe I should just go all in on flowers. I have several front beds that need attention. Or cucumbers and peppers, those always did well until the heat set in. Beans got absolutely worked over by the mites.

The kale and cauliflower will be fine, most brassicas are pretty cold tolerant (something like kale can withstand frosts at the end of the year, but will eventually get killed with sustained sub-freezing temps).

The others prefer warmer weather. A frost would for sure kill them, but I'd guess that they could survive a cold night or two if they're hardened off and are fully integrated into their spot.

I wouldn’t worry too much until the sun starts heating up the roof too much and you end up boiling the soil. Maybe see if you can raise them off the roof a couple inches for air flow underneath. The new leaves all look healthy, and that looks like sunburn or freezing on the leaves where it’s dying back. They look like big healthy plants, but I’d be careful they’re getting enough water. I don’t think the vibrations will be an issue until the fruit it ripe and you’ll probably drop a few from it if you don’t pick them soon enough.

I’d worry if the new growth is also getting burnt like that, only because that roof is designed to reflect sun back up and it might be getting the bottom of the leaves, but it probably won’t be a problem until July/August I’d guess.

Going back through my photos, it looks like I planted some potatoes with a few inch long eyes/roots growing out of them (don't know the technical term?) on Apr 25.

I don't have a pic of when I first say leaves, but the ones in the May 15th photo aren't hat big, so I would guess somewhere between May 5 and the 10th is when the leaves first sprouted up in that bin.

I have another smaller container with a potato that took much longer, I didn't notice leaves until later, (planted at the same time), though it's shot right up since then:

I grow a lot of potted things on my stone patio, and the heat island factor is very real, especially if you get temps over 100 like we do. You might want to look into options for shading them during the midday heat. I still haven't figured out a great solution.

For small scale, it sounds like worms are a common option, since a small compost bin/tumbler may not have enough bulk to really get going. On the other hand, we live in Vegas, so we have warm-to-really-hot temperatures for most of the year, so I'm wondering if that would:

1: Murder the worms all summer.
2: Help a 37 gallon'ish tumbler work alright, especially during the 7 months that our daily highs are over 80 (with 5 of those over 90).

This tracks with my experience with those varieties. The Chinese Pak Choi will bolt when it gets a little hotter from my experience, but it won't do anything once it gets summer hot. I was able to get a second planting done in the fall, but the plants were smaller and didn't do as well. The Shanghai did really well in my hydroponics though.

To be fair, my hydroponics were in a cooler basement in the winter where the average temp was about 64F and I didn't heat the reservoir. So it did really well (until I was overwhelmed by aphids whenI went away for 2 days). Other seeds that did pretty well from Kitazawa in the net cups were the Japanese Chard Umaina. I also did a bunch of microgreens (we liked the radish Triton Purple Stem microgreens the best, but the Upland Cress did really well too). The Chinese Pak Choi did fine in the hydro, and if you're going to have hotter ambient, it's probably the way to go too. It spread out more than the Shanghai which had a really tight leaf pattern.

Anybody have tricks for acidifying potting mix? Mrs. Chiller came back from a provisioning run with a couple blueberry plants and regular potting mix. I've attempted to cobble together something to keep them alive. We used some old bricks from a poorly constructed bed we tore off the front of the house, and a couple old tires to make kind of large pots/ beds. I heard evergreen needles will eventually help acidify, and we have a few massive Douglas firs, so I mixed a bunch of needles in with the potting mix, and whatever I could scroung up of old soil from out front, to fill out the beds. I've given a light dusting of sulfur, and dug it in around the plants, and put a thick layer of fir needles down as mulch. Fingers crossed they live. Everything I've read says don't fertilize for the first year, just let it grow roots and get established, so I've held off on adding anything else.
If I'm worried, could I add a bit of vinegar to the watering can?
Please share your general blueberry tips.

Pine needles don’t work.

In the short term, you can use vinegar or citric acid. Elemental sulphur, sulphuric acid, or ferrous sulphate will provide lasting acidity.

Platystemon posted:

So, you want acid in your soil.

Organic acids like acetic, citric, or tannic (in oak leaves) are not great because, well, they’re organic. They break down and the soil stops being acidic. Tannic acid what makes peat acidic and it kind of works there. Acid‐loving plants can be put in a soilless peat mix and they’ll do all right for some years, but mix basic topsoil with peat and the alkalinity wins.

Some organic blueberry farmers get by with acetic or citric acid, but they spend a fortune doing it. They have to because those three and agricultural sulphur are the only approved acidifiers for organic production.

Agricultural sulphur is just elemental sulphur. Put it on or in the soil and on the timescale of a year, soil microbes will capitalise on it and make sulphuric acid. That yearlong lag is why the blueberry farmers sometimes irrigate with citric or acetic despite the cost, but it’s great for maintenance. It’s cheap, it’s a mineral acid so it doesn’t break down like organics, and plants don’t mind or outright appreciate the added sulphur.

O.K., so why not skip the middleman and apply sulphuric acid directly? That can be done. It is done on a commercial scale, again, for blueberry farming. Handling and application are kind of a pain. It’s available on a retail level because it’s used to maintain car batteries and clean drains.

What’s in that bag I see sold in nurseries for soil acidification? Usually it’s aluminum sulphate. When applied to your garden soil, the aluminum precipitates out and the sulphur ion fucks off to become sulphuric acid. This works fine for hydrangeas. Aluminum is actually the pigment in their blue blossoms, but it’s toxic to rhododenra, azaleas, and blueberries.

Aluminum sulphate acted fast and was easy to handle. Shame about the toxicity. What if we replaced the aluminum with a less toxic anion? Great idea. Do it with iron and we get ferrous sulphate. If you’ve ever seen red dirt, it’s probably because it had a lot of iron in it. Plants don’t mind it a bit.

Ferrous sulphate is available at retail mostly for greening lawns. It is also sometimes used for staining concrete. It goes a moderately long way. A kilogram will keep a blueberry bush happy for long enough.

tl;dr: You probably want sulphuric acid or ferrous sulphate.

Hey great! Thanks for the info. I've got a bunch of vinegar, and have already added some garden sulfur for long term. Once it's time to feed, I've got ammonium sulphate, and some miracle gro for evergreens and acid loving plants.

Please share your general blueberry tips.

It’s Fir sawdust and bark that is used for growing blueberries. The needles won’t do much of anything except act as mulch. I’m not sure they’ll even give the structure to the soil that you want either. But as long as it’s fairly light soil and drains well and stays wet enough too, it’ll be happy. Blueberries are so particular and lazy about rooting. It’s also important to break up the root ball well so it must grow out too.

Adding the sulphur should be enough, I sometimes add coffee grounds, but it was more for me than anything else. They just go into the compost anyway.

Use a lot of pine bark mulch. Like way more than you think you need. Then in a few years buy some netting. If you don’t, you won’t get any berries.

The ammonium sulphate reminds me. The whole soil pH issue can be worked around with specialty fertilisers.

The primary reason plants demand particular soil acidity is that the nutrients have different mobility at different pH.



Iron is notably immobile in neutral or alkaline soil. Most plants excrete chemicals from their roots to help move iron. Blueberries cannot. They are specialised for acidic soil. Other plants would have the same issue with other nutrients in acidic soil.

Now, chelated nutrients, those are already wrapped up in an organic molecule and mobile in a wide range of pH. If you feed the blueberry bush a fertiliser labelled “for acid‐loving plants”, with chelated nutrients, it will be growing in normally inhospitable soil, but it will do fine because all the essential nutrients have been specially prepared for it. When it stops getting a regular supply of such fertiliser, its health will decline, unless, by that point, the soil has been acidified.

I’m looking into getting some drip line, pressure regulator, and a timer to better irrigate the garden this year (Hardiness zone 6a for reference). Can anyone recommend any particular systems, or all they all pretty similarly good/bad?

Also curious about this, although i only have 3 6'x4' raised beds. I'm thinking about doing lines of soaker hoses attached to pvc distribution lines.

I’m only right because I’ve made a bunch of mistakes trying to do it myself. The best thing to do is plan to start the seeds a month earlier next year in better conditions.

Bottom watering is good and they’ll send down that tap root before filling out the rest of the soil. It just takes time at about 70 degrees with enough light (I set for 16h) for it to do it efficiently. Adding some watered down fertilizer is a good thing to promote better growth too. Starting mixes don’t normally have any nutrients, unless they’ve started adding it. I have fertilizer that I use for hydroponics normally that has a good balance I like, so I’ll use that in my watering on an infrequent basis.

And I won’t lie, I’ve definitely bought backups before. It’s a great solution. Greatest trick out there.

Thanks, I think I'm going to get some fertilizer today. Not only have none of the transplanted ones done much of anything, it looks like my beans and peas, that initially shot right up, have stalled for almost a week (to be fair, the past few days have been very unseasonably hot, but I tried to make up for it with good morning and evening waterings.)

I'm am very unhappy with the garden blend soil I got. I think it's too much top soil, not even organic matter/compost. When I water, it makes the muddiest mud that ever mudded, and then dries into something that would petrify a dinosaur. Very hard and dry on top, with those large cracks you see in like salt flats (not that dramatic, but you get the gist.)

I at least mixed in some peat moss to most of it, but should have mixed in more or gotten some additional compost. Hopefully, by the end of fall, I'll at least have a bit of my own compost I can till into it to get it better prepared for next year.

More questions time. Here I have the biggest of the starters I bought as "backup":


It's a Super Sweet 100, which is one of the ones I am also trying to grow from seed. I think it's indeterminate(?), so as far as pruning, I should get rid of these suckers, right? I'm not 100% up to snuff on a "sucker" vs an actual branch/vine that the tomato needs to, you know..make tomatoes, but I think they're generally the ones that try to grow in those little nooks?

And should I also prune those two bottom branches? They are slightly yellow, though likely transplant shock, but I also heard it's good to not have leaves too close to the ground to help prevent disease and pests.

This world only remembers the results!




Went out and bought owl decoys yesterday, then replanted my corn
At least four seeds dug up by morning

Guess I’m just waiting for amazon to ship me some bird netting, then, and then replant my corn for the fourth time

When the light turns green, you go. When the light turns red, you stop. But what do you do when the light turns blue with orange and lavender spots?

Composting is not hard. It requires almost no effort unless you are trying to do it on too small of a scale. (which seems to be very in vogue these days)

I've been delaying starting in order to get the 'perfect' setup but that will never happen. So, how big of a pile are we talking about to make it an easy thing.

I don't know just how small you can go, but I can tell you that a 10 foot wide pile of shredded leaves that ends up being about 4 or 5 feet tall after they get "rained down" will happily cook all winter long in the northeast and end up with some really nice compost by the next spring. I do turn it every few months when I remember to - that definitely helps it go faster. But on that scale when I say "turning it" I'm talking about this:
