nettle-leaved mullein

Nettle-leaved Mullein (Verbascum chaixii 'Album') should be lightly watered throughout the growing season for best performance. Water near the base of the plant, being careful not to wet the foliage. This plant prefers evenly moist soil, but it is important to not let the soil become soggy. Generally, water 1-2 times per week, or as needed, to keep the soil lightly moist. A general rule of thumb is to give all plants 1 inch of water per week. In extreme conditions, such as prolonged heat waves, the plant may need to be watered more often, such as every other day.

Nettle-leaved Mullein (Verbascum chaixii 'Album') thrives best in bright sunlight during the warmer months, such as late spring and summer. In order to ensure healthy growth and blooms, place the plants in a location that gets full sunlight for 4 to 8 hours every day. It also tolerates some partial shade, but should not be placed in complete shade for more than a few days. Avoid overwatering this plant as it may lead to its roots rotting.

Nettle-leaved mullein (Verbascum chaixii 'Album') should be pruned in late spring. Pruning should involve trimming back dead, wilting, or fading flower stems, foliage, and spent blooms to promote new growth and help the plants look their best. Prune the plant early enough so that it still has enough time to flower again for the season, typically before July. Pruning to the ground level will help keep the plant tidy and encourage stronger growth in the coming year. For established plants, limit the amount of pruning to 20-25% of the leafy mass to avoid stress on the plant.
