Yellow King Humbert

The ideal time to plant Canna Yellow King Humbert bulbs is in the spring, once the danger of frost has passed and soil temperatures have reached around 60°F (15°C). In colder climates (USDA hardiness zones 6 and below), you can start the bulbs indoors approximately 4-6 weeks before the last frost date, then transplant them outdoors once temperatures have warmed up.

Planting the bulbs during this period ensures that they will have enough time to establish themselves and produce their stunning blooms during the summer months. In warmer climates (USDA hardiness zones 7 and up) you can also plant Yellow King Humbert cannas in the fall and leave them year-round in the ground.

Proper care for Canna Yellow King Humbert bulbs after blooming includes deadheading spent flowers to encourage continuous blooming and maintaining a regular watering schedule. As the growing season comes to an end, reduce watering frequency and allow the foliage to die back naturally.

In colder climates (USDA zones 6 and below), dig up the bulbs before the first hard frost, clean them, and store them in a cool, dry place over the winter. In warmer climates (USDA zones 7 and above), you can leave the bulbs in the ground, but consider adding a layer of mulch to protect them from colder temperatures.

Canna Yellow King Humbert bulbs are not entirely deer-resistant, but they are less likely to be favored by deer compared to other plants. While deer may occasionally feed on the foliage and flowers, the risk can be minimized by implementing various deer deterrent strategies.

These include using deer-repellent sprays, planting deer-resistant companion plants, or installing physical barriers such as fencing or netting around your garden.
