Yes, millet can be harvested when the seeds have fully matured and the plant has turned golden brown. This typically occurs around 70-90 days after planting, depending on the variety and growing conditions. It is important to monitor the crop and test the seeds for maturity before harvesting to ensure the best quality yield. **

Walnuts are typically harvested in the fall when the outer husk begins to split open and the nut inside is mature. This usually occurs between September and November, depending on the variety of walnut tree. It is important to wait until the husk has started to split open before harvesting to ensure the nuts are fully developed and ready to be eaten. Therefore, if the walnuts are showing signs of maturity and the husks are starting to split, it may be a good time to harvest them now. **

Grape leaves are typically harvested in the late spring or early summer when they are young and tender. Harvesters carefully select leaves that are free from damage or disease. The leaves are picked by hand, ensuring that the stem is left intact to make it easier to roll or stuff the leaves later on. After harvesting, the leaves are washed and blanched before being used in various culinary dishes. **

Comfrey can be harvested throughout the growing season, typically from late spring to early fall. It is recommended to harvest comfrey before it flowers for the best quality and potency of the plant. **

Savoy cabbage is typically harvested in the late fall or early winter. It is a cool-weather crop and is best harvested before the first frost. The leaves are at their peak flavor and tenderness when harvested at this time. It is important to harvest savoy cabbage before the weather becomes too cold, as freezing temperatures can damage the crop. **

It is difficult to determine if the bean was harvested too early without more specific information about the bean and its intended use. Factors such as the type of bean, its intended use (e.g. for consumption or for planting), and the specific growing conditions can all impact the optimal time for harvesting. Additionally, personal preferences for the taste and texture of the bean can also play a role in determining if it was harvested too early. Without more context, it is challenging to definitively say if the bean was harvested too early. **

Harvested sunflower seeds are typically roasted by first cleaning and drying them to remove any debris and moisture. The seeds are then spread out in a single layer on a baking sheet and roasted in an oven at a temperature of around 300°F for 20-30 minutes, or until they turn golden brown. Some recipes may call for seasoning the seeds with salt, oil, or other flavorings before roasting. Once roasted, the sunflower seeds can be enjoyed as a snack or used in various recipes. **

Iceberg lettuce can be harvested when the head feels firm and solid to the touch, typically around 70-90 days after planting. The outer leaves will be tightly wrapped around the head, and the leaves will be a light green color. It is important to harvest iceberg lettuce before it bolts, which is when it starts to produce a flower stalk and the leaves become bitter. **
