Which garden veggies have taproots?

Post  Marc Iverson on 8/26/2014, 2:25 am

This is an interesting subject in itself, I think -- whether a plant has a taproot may affect how easily it takes to transplanting and how tricky the timing might be, how well it endures drought, how deep a bed or pot it needs, etc.

Please share what you know about which common garden vegetables have taproots. If that affects or should affect the way we grow them, let the rest of us know!

Marc if you think about it all plants have a tap root somewhere on the root system, it's the longest  bit of root there is .

 Though I suspect you are thinking more along the lines of which long rooted root crop plants can we transplant easily .

 My experience is that if you grow the long root types in long tubes ( longer than the expected length of the root at transplanting time ) , you can carefully push the young plant and the surrounding soil out of the tube into a pre prepared hole close fit hole  . Do this when you have soaked the tube and contents for a few hours to get it sopping wet & slippery in the tube , eject the plant and soil into the hole  then water it in well in the new hole ,most of the time the plant will survive
 
I have successfully done this in my 3 inch tall bottomless tube plant tubes for carrots , radish , beet root , kohlrabi , parsnip , swede ( rutabaga) turnips , cabbages , peas , beans and all manner of other plants .

Sometimes when I've been a little tardy the tap root has actually grown down into the sand bed in the seed tray that  the tubes have been sitting on.
Careful washing away of the sand leaves the tap root undamaged and most times you can transplant it as above .

 By the way using quality MM is the best growth medium I've found so far for longer rooting tubes ( up to 15 inches deep length of plastic 3 inch dia rainwater down pipe  )

 You may have or not have noticed that Mel mentions using neat fine ( ish )  vermiculite for starting certain seeds , doing this in my 3 inch tall x 1 &1/2 dia tubes worked exceedingly well on such seeds that I found growing far too quickly on the high nutrients of MM filled tubes . It also pushes out the tube into the final planting hole very easy.

Thanks, I see what you mean.

I've noted that it is sometimes not recommended to start certain seeds indoors, sometimes with the explanation that in their starting pots their large tap roots will get too cramped in what I guess are the usual containers, and then I suppose not grow out right later. Or they said to be too tender to take to transplanting well. You nevertheless have success with some of those, like carrots. But you do take special measures. It's great that you've been successful that way.

Probably my question should have been more directed at what plants seem to suffer most from transplanting and which can, contrary to seed packet warnings, take well to transplanting. And if any special conditions and precautions nevertheless need to be taken with them.

I've been surprised now to read or see in real life that some plants it is commonly advised only to direct sow and not to transplant, like lettuce, beans, peas, and now your long list, can be germinated indoors and then transplanted out, or taken from their start somewhere in the garden and successfully planted somewhere else.

I don't know about taproots, but I've always had difficulty transplanting squashes, melons & cukes.  I have since found that if I transplant them before the 2nd true leaves appear, they seem to live.  I don't do well starting beans inside but some in the NE forum do it with good luck.

All my root veggies get direct seeded.  This time of year I like to broadcast lettuce & greens seeds and  then divide/transplant them later.

Hmm, I had a couple of melon transplants that did really poorly too. One died after a while, but one has never gotten better than thumb high. I'll keep in mind what you said about that and just direct sow if I try melons again.

Cukes I've only tried for the last two years, and the results haven't been too good with either seedlings or transplants. So maybe a lot of it is just my own fault somehow. I'll keep trying with seeds, for sure, since I have a lot now.

I found my mustard seedlings transplanted really well, but my kale and broccoli raab transplants quickly died.

I haven't found anything yet that can't be transplanted or up-potting using MM. But, I am very, very, gentle. Keeper transplanted a whole bunch of accidental carrot sprouts.

Marc ,

I suspect that the real naked reason for not sowing inside is twofold.

Firstly it is warm enough outside so the plants don't need extra heat or protection.

Secondly plants sown inside tend to grow too fast if the conditions are ideal. For some soft large cell plants this fast growth is not wanted much past the seed germinating otherwise the plant becomes lank & weedy.

Check out store purchased small herb plants where they have been force grown for a specific date of sale & you'll see what I mean  ... .  Those sickly looking  leggy plants are not a patch on something more naturally slow grown .
 The only way you can get those plants to thrive on the window cill is to feed them with a simple plant pot  food tablet which is fully dissolved in a half cup of water , then use this medicine to keep the plant just away from being too wet .
After a week or so the plant starts to pick up and become a stronger one.



 Next time you want to transplant a small seedling . Do your normal in taking the plant out the container and take a peek at the hair roots with a magnifying glass . I'm guessing that many will be damaged and the stem of the seedling or it's leaves will be d bruised .
 Now soak the whole plant pot with more of those plants for a couple of hours and gently move the growth medium about with a pencil so that you can see water down the pencil hole.
 
You can now almost pour the plant out the pot/tray .  Use a tea spoon to scoop out a seedling C/W the growth medium without disturbing the material around the seedling , slip it into that well pre watered hole previously mentioned ..don't touch the seedling with your hot greasy acidic hands or you will bruise & burn the seedling.
.
The more water in the material the easier it is for the plant to draw in nutrients and take in air as the material slowly dries out via its microscopic hair roots . The water will also help bind the plant's growth medium to the surrounding hole material , that's why the hole needs to be really well watered  .
 When they were alive  mum and dad used to refer to this as, "Puddling the seedling /plant in " .  They then ensured that the plant was almost over watered for the next three or four days till it became well & truly established.

 Melons & curbits ..did you know that these large flat seeds usually need to be sown on their edge not the flat  nor with a pointed end uppermost to get the greatest germination and strong plants ... nature takes care of the rest

How interesting!  I'll try that next year.  Do you know why it makes a difference?

Never heard of that. Generally the advice I see is about plenty at depths of some multiple of the seed size. I'll try to remember that for next time.

Thanks for all your transplanting advice too. I do water seeds in, and give them extra water when transplanted, but it sounds like you have been much more careful and fastidious about it than I have, and therein probably lies the difference.

 I suspect it is to do with the pithy surface skin of the seed being able to drain excess moisture off a vertical flat  instead of it soaking through when it is flat  and rotting the seed germ before it manages to get growing .

Gravity & magnetism  also affect how the seed grows .( I only read about that a few months ago )  



Which edge  ?.... draw a symmetrical oval shape 1 inch long by 1/2 an inch wide .... longest dimension are the end edges so plant the seed on its side with the shortest dimension in the vertical .

Good grief!  rofl  Over thinking is one thing but please use some common sense folks.

Seeds know how to go naturally.

I for one enjoy the obscure after years of same ol' same ol'.  I'd soon get bored of gardening without an interesting learning experience or theory to test once in a while.  This one certainly isn't time consuming.  It's just as easy to plop a seed in sideways as flat.
