Re: Raditz
There's no evidence suggesting that Radittsu had Saibamen to plant. Even if he did, I highly doubt the Z Senshi would allow him the free time to go about planting them, let alone water them to get them to grow.
However, even without their help, I highly doubt that the help of the Z Senshi would have improved the outcome of the fight much, as apart from Tenshinhan's Kikoho, no attack the additional members of the Z Senshi had would have much of an effect on Radittsu at all. Furthermore, since Gokuu was able to avoid it when they had about the same battle power, I'm confident that Radittsu would be able to avoid the Kikoho as well.
