Castor Beans not growing huge like pics I've seen
For some reason my Castor Beans that are Zanzbar (seeds purchased from Ebay seller) I only have 3 that survived the lawn mower and the biggest is about 3 feet tall. One is Puny and sickly looking.
The Pics I see on the Internet are of Giant multibranched plants.
I have them in full sun and our soil is sandy, Any suggestions..
