Keeping your beautiful geraniums healthy and blooming all summer requires more than water and fertilizer. You have to be on the lookout for bugs, especially this little guy. He can cause lots of problems for your hanging baskets and patio pots. The Tobacco Budworm starts to show up in your garden around this time of year. Signs that your plants have been attacked by budworm include tiny holes in the flower buds and small dark specks on the leaves and stems. The little dark specks are really the worm’s waste. The budworm caterpillars usually go after the geranium flower buds. The damaged buds won’t open and you notice your geranium has stopped blooming.
