Taproot

Taproots are the thick primary root that normally grows straight down under the soil. In most cases, this is the first root that forms from the seed and is the main root anchoring system that the feeding roots grow from. As a result, the taproot provides the most nutrients to the plant. It is also the strongest and largest root and tends to burrow itself deeply into the ground.

A taproot is usually a thick root that tapers gradually. In some cases, a taproot can be forked or be framed by thinner lateral roots.

Plant roots are categorized into three main categories: taproots, branch roots, and adventitious roots .

Maximum Yield Explains Taproot

All plants have roots – the serve to supply the plaint with nutrients and moisture, and in the case of plants grown in soil, they help to anchor the plant in place. However, not all roots are the same. Pull up a plant, and you’ll find roots of all sizes and thicknesses, but you’ll most likely find that there is a thicker, longer central root off of which most other roots grow. This is the taproot.

Most plants, including cannabis plants, have a taproot. The taproot is the first root formed from the seed of the plant upon germination, and, while the plant will have other roots, it will remain the longest and thickest. It will also grow the deepest in the growing medium. Think of a carrot – the part that we consume is actually the plant’s taproot.

In some plants, such as carrots or radishes, the taproot is actually an organ that stores the major nutrients and vitamins. As a result, these taproots can be cultivated for eating. Other plants with taproots include parsnip, parsley, dandelion, sugar beet, burdock and beetroot, among others.

Not all plants have taproots, but those that do have specific benefits over those that do not. Because the taproot burrows much deeper into the ground, these plants are generally much more drought tolerant, as they can continue to locate moisture deep in the earth even in dry conditions. A butterfly weed can grow in sand or gravel because its taproot extends beyond the surface and is able to draw water along its entire depth. In addition to its water-gathering ability, a taproot provides additional stability in high winds for tall trees like the oak or ash. Another benefit is that taproots can also store nutrients for the plant, providing nutrition and helping to make plants more self-sufficient.

Of course, taproots also cause some problems. A taproot on a tree like an oak usually isn’t an issue for gardeners, but they can be problematic for weed control. Pulling a dandelion, for example, can be difficult because they generally snap off at the top of the taproot. If the taproot is not completely removed from the soil a new plant will grow from it.

Seedling is growing upside down, taproot is above the soil!

Is your cannabis seedling growing upside down? Has the tap root come above the soil?

If your root is growing straight up like in the picture below, it’s not good. This is most common in seedling plugs. The tender white root tip has a good chance of drying out or being exposed to too much light. You want to strongly consider doing some “plant surgery” to turn this little seedling around to the right direction

The first thing to do is get a new Rapid Rooter. Since your seed already has a relatively long root, cut the plug open lengthwise so you can gently place the seedling inside in the right position without having to “push” down on the seed.

Now gently extract the seed from its original home with a pair of tweezers making sure to touch only the shell and not the root (the root is the most sensitive part)! Now lay the seedling in the middle of your newly split open Rapid Rooter and gently close the plug around it again.

Most seedling plugs will go back into place easily, and you’ll barely be able to tell it’s been opened

Since your seedling has already sprouted and has been in placed into the right growing position, it’ll probably pop its head out within just 12-24 hours! Sometimes you see just the leaves, but occasionally you actually see the seedling push the shell above ground.

When this happens the shell usually falls off on its own as the seedling grows!

When Should I NOT Do Surgery?

Sometimes you can see the young taproot of a cannabis seedling but the situation isn’t as dire. If the root is already pointed in the right direction, it’s probably going to be just fine! But if you’re worried, you can cover up the root until the leaves actually make it to the surface.

For example you could tear a tiny piece off the edge of this Rapid Rooter and gently lay it on top. Or if you were in soil you could sprinkle a tiny bit of soil over the seedling. The seedling will push it off as it grows upward.

This case isn’t so bad because the root is already facing down, in the correct direction. Note: This seedling was just watered, but typically the Rapid Rooter should never look this wet. It should be moist but not shiny.

If you leave it alone, the seed will start to rise up, and open to reveal the seedling’s cotyledons (first, round leaves)

The cotyledons unfurl and then the regular cannabis leaves between to grow. Here’s another view of that same seedling from above only a few hours later. Even though it may have looked a bit weird at first, this seedling is completely normal and will grow just fine from now on!

Most of the Time Seedlings Take Care of Themselves!

When you see your seedling looks like this, where the part of the root exposed to the surface already looks green like a stem, you don’t need to do anything.

After germination, the tip goes down and stays white, and the other side that’s contained in the shell tries to work its way up, and that part of the stem turns green. Sometimes it looks like the root is going upside down because it appears that it’s not strong enough to be able to push the seed up.

As long as the tip of the root stays wet the seedling will be fine! The “root” is the same as what is going to become the stem. If it appears green it means that part of the root is already in “stem” mode and isn’t sensitive to the light.

If you just wait a little everything will have righted itself Here’s that seedling 12 hours later…

12 hours after that, the leaves have completely emerged!

If you hadn’t been watching you wouldn’t even have known anything happened!

How big should a tap root be for planting?

Basically a friend got some seeds. One was broken so he germinated it for shits and giggles (his real grow won’t go on for another couple of months). Any way he was wondering how large his tap root should be before planting? Right now the seed is cracked open on one end a little with tap root is sticking out the side (I mean it’s tiny) but it’s a very noticeable germed seed. You think he should wait a day or so more and let the little root get bigger or is it ready for a planting. FYI he’s going to either use soil or a small hydro setup just for this one little seedling (would either setup require a differently sized tap root than the other?).

plant the tap root facing down..the minute the seed cracks and u can c it..id reccommend using tweezers to place it in ur medium..ive had bad luck touching my tap roots with my hands..and prefer to germ st8 in2 soil without the paper towel hassel and exxtra handling..but ea 2 there own..good luck

Cool thats what I though you plant it once it cracks. Yeah I knew to plant it face down. I just didn’t know if letting the seed’s tap root get a little bit larger before planting would help out much in terms of it being more vigorous and accustom to it’s new medium. A lot of photo’s I’ve seen of germed seeds seem to have exaggerated tap root size. Most likely I imagine to illustrate a point.

yes plant as soon as bean cracks show white plant with root and pointed end down amust. then i cover with a plastic bag or ceran wrap over starter cup until shows through soil then under flour light for three weks as seedling just distilled water and thrive a little root stimulator and a drop of peroxide. fourth week veg starts transplant under big lights if limit of light is 18 inch im under at 20 inch the first week raise every week until reach loimit of ligh food also starts 4th week at 1/4 strenth feed everyother water I normally water dry for 2 days food dry for one day repeat. but what do i know growing since this January on my 4th grow lucktoyomybrother.

Cool thanks guys. I think my buddy might just give it a day or so longer only because he has to guy some supplies. But yeah it’s pretty shocking this thing germinated. It literally was missing 2/3s of it’s shell and looked a bit crushed and miss colored. But yeah I do know a lot of the fundamentals of growing. My buddy and myself have grown a lot of other types of plants before so I don’t think he’s all too worried. Neither one of us have germed seeds in a paper towel ever so I’ve never actually seen how a tap root looks in real life.

Also should my shine a light on the seed growing in the medium? Or should he wait till it sprouts out of the medium (i.e. the point at which it isn’t quite a seedling/still looks like a sprout)? I mean in theory wouldn’t help growth as the sprout is growing out of the medium for light? I was going to tell him to use something in the 10-20w range for this? Or is it not even needed?

id say sure throw a small floro or cfl above. it helps dry the soil out and create humity..especially if u cover the pots i saranwrap like dude said.. creats a humid environment..when they sprout and grow in2 bumping the saranwrap i take it off. i also use a heat pad underneath to push humidity and dry the soil..increased germ rate and speed.

no light is needed until sprout shows through soil then right away not to close and by the way when i have seeds that wont split i use scarsification scratch sandpaper scrape along edge that splits crack open just dont go deep enough to damage seed inside.luck to you my brother

Thanks for the great responses guys! Hopefully this seed is a female. As I said earlier this isn’t my buddies main grow. That won’t happen for a few months or so (for that grow he’s throwing down big bucks, and making some nice hydro setups/legal grow rooms). I think he’s more curious to see if this sucker will grow at this point. Not even fruit even. It’s more or less just fun science experiment. I think at most for this one little seedling my buddy is willing to commit to 20-30 dollars worth of supplies and a minimal amount of time.

Other people in this thread seem to think that it’s a good idea to plant the seed as soon as it cracks..however this can be a bad idea..the tap root is what gives the plant its early root structure..and strength..allowing them to have this before planting gives the seedling a much better chance to survive any problems it may encounter in the soil..remember..soil is a living organism and has bacteria..a seed may get halted in its early growth by encountering any numbers of chemical reactions including chlorine shock..pests..or fungus..the ones with a half inch tap root..seem to be able to cope better..

the best thing is to let the seed develop a tap root to a length of about a half inch. I am also going to recommend and assume that you knew enough to let the seed(s) bob around in a glass of water that was allowed to sit for a few hours (to allow chlorine to gas out of the water. before putting the seeds in). and then put the glass of water and seeds into an empty drawer somewhere where there are no lights..and leave it there for 12-14 hours..”longer will risk drowning the seeds”..then you should have triangle folded a and dampened brown coffee filter..not white..white ones may contain bleach..which is also chlorinated..put the coffee filter triangle in a small tray and put the seeds very gently onto the filter..”don’t squish them or they will die”..after their soak they are delicate..so do this carefully..put a “once folded” coffee filter on top of the seeds..and wet it ..

you will see the outline of the seeds through it slightly once it’s wet..put the tray back in the drawer and use the water in the cup to wet the top filter a couple times each day..DO NOT LET THE FILTER DRY OUT BUT ALSO DO NOT LET THE SEEDS SIT IN A PUDDLE..after about three days the tap root will be around a half inch on the seeds..if not leave them until they are..once the seeds are ready..plant them each in their own small 4 inch pot by poking a whole down about an inch with a chopstick or your finger..

gently place the seedling tap root down and gently push some soil in around it and then cover it gently with some more soil ( make sure you use regular potting soil with a decent amount of peril it in it..I like shultzs potting soil) spray (water @ 6.5 ph) the soil till it’s dark and wet but not puddling..place the potted plant under a 1300-2600k daylight (for vegging cycle) CFL..about 3 – 4 inches from the pot ..in about 2 days or less you will see your new seedling popping through the soil..if it takes 3 days I will be surprized..keep checking the seedling about 3 times a day..make sure to fine mist spray the soil and keep it dark..as the light will dry it out..don’t let it dry out until your plant gets about 4 inches and has its first real growth leaves..

Then water the soil as you would with regular plants..allowing the soil to almost dry out up to an inch below surface..I usually water when I see the edges of the soil pull away from the pot sides..but for the seedling when it is still just in the baby leaves..keep the surface damp ..by watering or checking it every few hours..keep a light breeze (fan) circulating in the room..not directly on the plants though..especially when they are little. good luck
