I love this shade of yellow and am pleased that many of the Calendula seeds I sowed in the Spring are growing in my garden. Calendula are easy to grow. You can sow them indoors for early bloom, they also do well direct-sown into the ground, and are often part of wildflower seed packets. There are many medicinal uses for Calendula, making them a powerhouse plant when you consider the beauty they add to the garden. I’ve planted Calendula in hanging baskets, in pots, and in the ground. Calendula also bloom in a lovely cantaloupe shade of orange.
Unfortunately, that lovely yellow color and bright green foliage makes the Calendula a prime target of whiteflies and aphids. Aphids are easy to control with a dousing of the hose or handpicking. Whiteflies are not as easy, and need a bit of baiting to be trapped. I used the same beautiful yellow color to lure them to their demise.
I gathered a few items together, a yellow plastic cup, clear packing tape, string, scissors, and a paper clip.
I punched a hole in the bottom of the cup with the scissors, and strung the string into it with the paperclip opened up to keep it in place. I wound the tape around the cup, sticky side out, covering all the sides.
I hung this near the area of whitefly infestation.
Success! The whiteflies, attracted by the yellow, landed on the sticky tape and met their fate. It has rained, and the tape is a little less sticky now, but it’s easy to replace. This is a low-cost fix for pests with the plus of using no harsh chemicals. Brushing the plants near the trap several times a day causes the flies to swarm off the plants and helps the trap capture more of the pests.

If you don’t want to make your own traps, whitefly sticky traps are also available in hardware stores and garden centers.
