I wrote earlier about calcium deposits from the fertilizer on our poinsettias leaves and it was suggested that we try rinsing them with Capsil. I called Scotts for a local supplier but they told me they do not carry it anymore and recommended I call Aquatrol and they had the product I needed. I called Aquatrol and they said they do not handle it anymore and that I should call Wilber Ellis. I contacted them and they gave me a product called Sylgard (a silicone surfactant like Capsil) that they said was better. I applied it at the rate of 1 ounce per gallon and then rinsed it off and waited till the two test plants dried off and they still have spots. Any ideas?
