What soil and feed do I need to get the largest heads on geraniums.
Would welcome advice.
Do I take it you mean the sort of geraniums that are now called pelargiums? Frost-tender bedding plants?
Are you growing these in beds or pots?
Why doesn't everyone call the bedding geraniums pelargoniums? GC always refer to them as geraniums. There wouldn't then be confusion
Thankyou for info. What soil mix would you recommend. For high nitrogen, would miricle grow be the right one and should I add a third grit. If I wish to take cuttings what is the best method.
Thankyou for suggestions. Seeing that you recommend John Innis number 3 loam based soil implies to me that I should start off with a high food content plus a third grit, then move over to a high potash feed when buds are developing. When successful, what method do you use for taking cuttings. Do I need bottom heat this time of year with a lid to hold in moisture and then put in shade plus rooting hormone powder. Hope I have not bent your ear too much!!
