How to Get Foxglove to Bloom

Plant foxglove in early spring or in the fall when started as clippings or in the summer as seeds for the best results for your blooms. Water them once a week with about an inch of water each time. Increase the watering a little during particularly dry periods. Flowers begin blooming during the plant's second spring when started from seeds, though if you bought the plant from a nursery, you may see blooms starting from the following spring after planting.

Deadhead the blooms once they begin to droop and completely remove the flower spikes. This will encourage the plants to produce a second set of blooms shortly after the first set begins to die, according to the National Gardening Association. When deadheading, remove everything but the center spike-growth because it helps the plants to self-seed.

Plant a batch of seeds the first year and then a second set of seeds the second year so that you have a continuous cycle of new blooms from different sets of plants.

Place foxglove in full sun to partial shade, though too much afternoon sun could cause heat damage, which then could cause the plants to produce fewer blooms.
