These are planted transplants or just seedlings? Very different things when it comes to fertilizers. Since both are normally direct seeded in the garden, not grown from seed and then transplanted, it is an important bit of info. Neither tolerates transplanting, especially radishes.

So if you are talking about seedlings - no.

If you are talking about established plants in the garden - sure a 1 time only side dress application of it is fine for the radishes worked well into the soil but not for the beans.

Beans, like all legumes, don't tolerate or need high nitrogen fertilizers. Over use of fertilizers on legumes results in big leafy plants but few if any beans.

Thanks again Dave, you're always so helpful. What would be a good fertilizer to use on bean & radish starts?
