What yield and income range can Calendula give, honestly?

Calendula yield and income vary a lot by climate, management, the form sold and the buyer, so plan with conservative ranges and verify locally. Dry flower or petal yield per acre falls in a modest range, and the price per kg of dry flower or petal is buyer and quality driven, with bright clean dried material earning more. Against the income you must set the heavy hand picking labour, which is a real cost over the flowering season, so cost that in honestly. Because it is a specialised buyer driven crop, do not budget on a single high number a promoter quotes. Build your plan on the low end of yield and price, confirm a buyer and a written rate, factor in picking labour, and treat all figures as unverified ranges until you have actually sold a lot.
