To pollinate your cup plant, you can use a soft brush or cotton swab. Gently touch the male flower with the brush or swab, making sure that you collect enough pollen. Then, transfer the pollen to the female flower by touching it with the same brush or swab.

Repeat the Process

You will need to repeat this process several times to ensure that all of the female flowers are pollinated. It is best to do this in the morning when the pollen is fresh.

Protect Your Plants

After you have pollinated your cup plant, it is important to protect it from pests and diseases. You can use organic pesticides and fungicides to keep your plants healthy.

Harvest Your Seeds

Once your cup plant has produced seeds, you can harvest them by cutting off the seed heads with a pair of scissors. Make sure that they are fully mature before harvesting them.

By following these tips, you can increase your yield of cup plant and enjoy its beautiful yellow flowers all summer long.
