King's Lynn

King’s Lynn gladiolus is considered a perennial plant, meaning it can grow and bloom for multiple seasons. However, they are often grown as annuals in areas with cold winters, as they are not cold-hardy and will not survive frost. In such regions, they can be planted in the spring and will bloom in the summer, but will need to be replanted the following year.

In warmer areas where the soil does not freeze, gladiolus can be left in the ground to grow and bloom year after year. In the wintertime, give them an extra layer of mulch. King’s Lynn gladiolus are hardy in USDA climates 7-10, which means if you live in this area, you can leave your Gladiolus outside. Otherwise, you have to dig them up. They are prized for their tall spikes of colorful flowers, and are often used in cut flower arrangements.

King's Lynn gladiolus bulbs require regular watering during their growth period, which typically lasts from spring to fall. These plants thrive in well-drained soil that is consistently moist but not waterlogged. They should be watered deeply once or twice a week, depending on weather conditions and soil moisture levels.

If you’re not sure when to water King’s Lynn or not, just feel the top inch of the soil. If it is still wet, then you don’t need to water it, if it feels dry, then you can water it. Aim to water early in the morning or late in the day to prevent evaporation and leaf scorching.

King's Lynn gladiolus should be cut back after the first frost of the season, which typically occurs in late fall. At this point, the leaves of the plant will begin to turn yellow and brown, indicating that the plant is going dormant for the winter.

Once the foliage has completely died back, you can cut the stems down to the ground using a sharp pair of garden shears or scissors. It is important to remove the dead foliage to prevent disease and pests from overwintering in the plant. By cutting back your King's Lynn gladiolus at the appropriate time, you will help ensure a healthy and vigorous plant for the following growing season.

The best fertilizer for King’s Lynn gladiolus is one that is high in phosphorus, as this nutrient promotes healthy root growth and flower development. A good option is a 5-10-5 or 10-10-10 fertilizer, which contains a balanced blend of nitrogen, phosphorus, and potassium.

Apply the fertilizer at planting time and again once the gladiolus plants have started to grow, making sure to follow the manufacturer's instructions for dosage and application method. It's also important to keep the soil moist but not waterlogged and to provide the plants with plenty of sunlight and good drainage to ensure optimal growth and blooming.
