how to harvest calendula - #26754
I am really confused about how to harvest calendula. I have this little garden in my backyard where I planted some calendula plants a few months ago because I heard they’re good for skin and all that. But now I’m worried because they’re blooming like crazy, and I’ve been reading stuff online about when and how to harvest calendula but it all just seems overwhelming. I’m not sure if I should be picking the flowers or cutting the stems or what. Like, some articles say to wait until the flowers are fully open but others say pick them before they fully open for the best potency. Are the petals the part I should focus on? And I heard there’s a specific way to dry them too. Should I leave them in a dark place or can I just hang them up somewhere? How do you even store them afterward? Ugh, I don’t want to mess this up! I really want to use these for making oils or maybe in some homemade creams, but I need to get this right. Anyone got tips on how to harvest calendula without ruining it? Would love any advice!

Harvesting calendula can indeed be a bit daunting when you’re trying to get everything just right. Let’s break it down so it’s more manageable for your backyard gardening. First, aim to harvest calendula on a dry day after the morning dew has evaporated—this helps prevent mold when you’re drying them later. The best time to pick your calendula is when the flowers are just fully open. You’re right about the varying advice out there; however, harvesting them at full bloom is generally considered optimal for achieving the highest levels of essential oils. Focus on picking the flower heads themselves, not the stems. Simply use your fingers to gently snap off the flower head from the stem; though be mindful not to pull too hard to avoid damaging the plant.
Once you’ve collected the flowers, you’re going to want to dry them thoroughly. You can spread the flowers in a single layer on a mesh screen or a clean cloth in a warm, dry place away from direct sunlight. Good air circulation is especially critical to prevent mold. You don’t need a very dark place, just somewhere out of harsh sunlight to maintain the vibrant color of the petals. Alternatively, you can hang smaller bunches upside down in a similar condition. Drying usually takes about one to two weeks, depending on humidity and temperature. Make sure the flowers are completely dry and crumbly before storing them. For storage, keep the dried calendula flowers in an airtight container—glass jars work well. Try to store them in a cool, dark place to keep them potent and vibrant.
As for using calendula to make oils or creams, once they’re dried, you can infuse them in a carrier oil of your choice by placing the dried flowers in the oil and letting them sit, traditionally for 4-6 weeks. Straining the oil afterward will give you a calendula-infused oil, which can be used as is or blended into homemade skincare products. Keep your infused oils in similar conditions, always sealed tightly to retain potency. With these steps, you should be able to effectively harvest and preserve your calendula flowers for a variety of uses.
