Hello everyone welcome back to the epic gardening podcast today we're talking about the humble

0:05.7

radish one of the best little garden poppers out there and when I say poppers I mean you can pop them into little nooks and crannies in your beds or you can just pop them out of the soil into your mouth or into a salad or some sort of fermented action.

0:20.0

So today we're talking about why they don't bulb up.

0:23.0

And so there's four different reasons why this might be happening.

0:26.0

And of course there's more than four, but these are the four most common that I've run into.

0:30.0

So let's go ahead and figure this out.

0:32.0

The first one is going to be too little sunlight.

0:35.2

A lot of people consider radish to be a winter crop, fall winter, early spring crop.

0:40.1

Certainly that's true, but they do want as much sun as you can give them you know

0:45.0

four plus hours minimum I would say definitely six is preferable or even more

0:50.4

so if you're not giving them enough sun, they can't photosynthesize and they cannot make enough energy in order to actually bulb up that route.

1:00.0

So I would just increase the sun. That's my first tip. Number two, too much nitrogen in the

1:05.1

soil, not enough phosphorus and not enough potassium. Nitrogen, as we know, really big contributor

1:10.3

to leafy green growth, the actual vegetation of a plant, whereas phosphorus and

1:15.0

potassium are used in much higher amounts during the fruiting or the flowering or the

1:20.9

bulbing phases of a plant's growth.

1:23.4

So if you're having a lot of tops and not a lot of bulbous roots,

1:29.1

well then it's probably the case of too much nitrogen.

1:31.8

So you can fix that by adding a little bit more of

1:34.4

potassium or phosphorus or you can just sort of amend and hope that you sort of bring down that percentage of

1:41.7

nitrogen in the soil.

1:43.0

Next is going to be temperature.
