Al, I don't know how you feel about E-Bay, but this listing has all three you requested and more. I have personally had nothing but the best kind of experience with E-Bay sellers, though not with this specific one. Donna Here is a link that might be useful: Multiple Castor Bean Seeds Available

I have voles and possibly moles. I've seen the voles (mouse-like creatures) but I have loads of tunnels in the yard. So maybe that is a mole. Farm stores and big box home and garden stores have granules which are labeled non toxic and won't harm pets. You have to get the granules into the tunnels and water it in. My understanding is you water and do more granules going towards the end of your property lines, driving them away. To be honest, I did not want to fool with the watering part. There was also an earthworm-looking bait, it looked like a fake rubber earthworm, supposedly they eat it and it kills them. I didnt' want to use this becoz I have a small dog, and altho I don't think she would get into the tunnel and eat the earthworm bait, one never knows. And then poison bait not eaten will get into the environment. The next gizmos were solar-powered and battery-powered sonic emitters. The thing made a beep every 30 seconds, which I didn't like. So far I have decided not to intervene, becoz, while I have lots of tunnels, I don't see any plant damage, all my bulbs are up etc. So we are peacefully co-exisiting at the moment. Laurie

If your request for castor bean seeds hasn't been satisfied yet, I've got lots and gladly send you some.

My guess is that they need more water. Castor beans are tough and very drought-tolerant plants but when getting established as seedlings, they form a very long taproot. If your soil is dry and sandy, and especially if you had the same early spring drought that we did in the mid-Atlantic, they may never have gotten established properly. Also, they generally need little fertilizer but in sandy soil it may help to give them some. I think it's too late for this year, but maybe they'll do better for you next year. The size also depends on the selection you are growing. Many of them are selected to stay small, and will start blooming at a small size. If you want really big castor beans, you need to seek out the really big selections like 'Zanzibarensis', which has enormous green leaves. BTW did you start them directly in the ground? I find this is best, because it allows that long taproot to grow. Starting them in pots usually just stunts them (although I've had some luck with peat pots). Also, they do best in full blazing sun, although again they do need some water, especially when young.
