I bought a hollyhock plant with beautiful flowers. I replanted it in a large earthen pot. It is growing beautifully with lots of buds, but just before blooming the buds become brown and fall off. What am I doing wrong? It is in full sun and well watered.

I would inspect your hollyhock for an insect infestation, particularly for thrips. More information on thrips can be found here: https://www.gardeningknowhow.com/plant-problems/pests/insects/controlling-thrips.htm
