It is normal for the oldest leaves on a geranium to turn yellow and drop off the plant. The key to keeping lots of green leaves all ove the plant is to regularly pinch out the growing tips of each stem. This forces growth towards the center of the plant and also at the tips of the stems. The more you pinch, the more new stems and leaves will develop. So, pinch the tips of the stems out to make your plants fuller and to encourage replacement of the old, yellow leaves.

One of the most common reasons for failure of the flower buds to open is a bud worm. You can snip off a few of the flower buds, open them up and see if you can find a little green worm. Or look for an exit hole on the sepals (green covering over the flower bud). These pests are difficult to control because the adult is a moth and after the worms feed on the flower buds they pupate in the soil beneath the plant. You can't control the moths but you can scratch the soil surface to expose the pupa to predators and the weather.

Good luck with your geraniums.
