When do all plants generally release their pollen?

Plants typically release their pollen during warm, sunny days due to several factors that promote pollen dispersal. Warm temperatures help to activate the plant's reproductive processes, making it more likely for pollen to be produced and released. Sunlight also plays a critical role; many plants require light to stimulate these processes, and the warmth from the sun helps to dry out the pollen, allowing it to become airborne more easily.

Moreover, on warm, sunny days, there are often conditions that help the wind carry the pollen to other plants for fertilization, enhancing reproductive success. In contrast, cold or rainy days can inhibit pollen release, as humidity can cause pollen to clump together and settle rather than disperse into the air. Nighttime pollen release is uncommon, as most plants that produce pollen do so during the day to maximize the chances of its dispersal, and only certain specific plants demonstrate unique pollination strategies. Similarly, pollen release during storms is not a general behavior of plants; storms can disrupt normal pollen dispersal patterns rather than facilitate them.
