Seed Pod Weed

Seed Pod Weed

Hairy Bittercress (Cardamine hirsuta)

I’ve become fascinated with this weed, at least so far. I’ve more-or-less got it under control in my garden. I really don’t remember it from years ago, but it sure has been a pest the last 5 years or so. Not a native of California, it is now here for the foreseeable future… and beyond. I can’t say it’s the worst weed in the garden, but it sure requires attention to keep it under control. Especially these days when it will be competing for available water.

Even if you didn’t recognize it outright, maybe you’ve had the experience of being out in the garden pulling winter weeds when you’re pulling what looks like a small “innocent” weed only to find it exploding seeds in your face and all over the nearby garden? The most likely culprit is Hairy Bittercress (Cardamine hirsuta), which starts growing almost immediately with the onset of the late winter rains. It originally looks like a small, flat rosette of small leaves and then in what seems like the next day, quickly produces small white, four-petal flowers on wiry green stems. Most of the problems with this weed can be “solved” if you pull it at this stage or at least before it flowers. Seemingly overnight, the flowers form needle-thin seed pods, which explode at the slightest touch, sending seeds in all directions (averaging around 600 seeds per plant… and the bigger the plant, even more seeds). Besides your garden, the seeds are easily propagated in cracks in flagstone, brick or concrete walkways.

Because Hairy Bittercress thrives in moist conditions and disturbed soil, it is also a pest in nurseries, and can be brought home via plant purchases. If you think that’s a problem for you, some cautious gardeners carefully remove the top inch or two of soil in the pots before planting. (If you do this, you should dispose of the scraped-off soil in your green can.)

If all else fails, Hairy Bittercress is a member of the mustard family and is edible, but you need to do your own research to find the right recipe to enjoy it (for an example, see http://www.eatingniagara.com/2013/04/weed-wednesday-make-that-hairy.html). To get ahead of its persistence in the garden, it’s definitely worth patrolling your garden for this weed once or twice a week during the winter and spring. It’s easy to hand pull when young. Once the seeds pop, you’ll be fighting a much bigger crop next year and it’s rare that herbicides would be considered appropriate for control in a home garden.

Another reason it’s my “favorite” weed? I still remember a fellow student in our Master Gardener class relating how she had “convinced” her young son to help weed the spring garden and he was complaining about the weed seeds popping in his face. She answered him by telling him to go in the house and get his safety goggles on and keep on weeding… something you might be considering adding to your gardening tools if you let Hairy Bittercress (Cardamine hirsuta) go to flower and reseed.

Seed pods everywere

Well today I was looking at my plants, and the big one has seeds everywere. It has been flowering for about 2 monts now, under a 400 hps. Well when I checked it, they were everywere. Can I just pull them off? Should I just leave it?

It’s my biggest plant, looks very healty, but is right next to my other plant. I don’t wan’t to chop her, but I don’t want this to happen again.

I live in Cal. so I have the clinics. Is it not good to get plants from them?

Thanks for your time.

The thread title said seed pods everywhere. Every female plant has seed pods. A little known cannabis fact is that each individual seed pod is a cannabis flower. Entire buds are not actually flowers, as in individual flowers, but instead clusters of many tiny flowers, the individual seed pods/flowers that grow together and create buds. Each seed pod/flower will ‘plump up’ and appear to have seeds in them when they near maturity. They will give an appearance of having seeds inside, but not have seeds in them.

If your plant’s seed pods/flowers have seeds growing in them there are only several possible causes. Hermies, or a male or males that were not removed prior to releasing pollen or an outside source for pollen that is carried by wind or brought in by someone and then transferred by inside air currents resulting in pollination.

They are mostly red hairs now.

There are cressent shapes at base of stems, but none of them have seeds at all.

I have been doing some searching on this sight, and It seems some people have seeds in their buds, and some have obvious male characteristics, more near where branc meets. If I no signs of seeds at base, and no bananas, is it not a hermi?

I checked light and there were no cracks, but I am aving issues with heat. Sometimes I come ome and its like 90+degrees and 30 or less on humid. Is that the issue?

Thanks for the help guys

i have a lr2 that has pods but they don’t hang down, they are pointed up and i just noticed that the lower clumps of pods have white hairs coming out. i clipped an couple pods off and dried them, nothing inside. i was hoping it was a male so i could grow seeds. is this a hermie? it doesn’t look at all like the females i’ve grown. there are trichomes not many compared with past plants. will it produce pollen?? thanks

I had bananas show up a week or so ago and now budds are filled with pods, which have liquid in them. Am I in trouble?

Calyxes are seed pods, if they get pollenated they will grow seeds, if not they swell up with resin. Trichomes are the “crystals” that protect the leaves and calyxes from insects and fungal disease.

If you have fully mature seeds in your buds then you can pull them out or leave them it’s up to you. A few seeds won’t hurt anything as long as you don’t smoke them

So far, they are full of liquid, but there are so many, and look like seed. Budds are full of them. I also had the little bananas show up a couple of weeks ago, then the pods. I actually took down 2 plants today, and budds are full of these pods. I think I’m screwed.

Here are pics of mine. Looks like seed pods, but only liquid inside. Any Suggestions or comments? Thanks.
