Rik's Frizzle Gladiolus bulbs have the potential to multiply every year, but the actual rate of multiplication will depend on several factors. Gladiolus bulbs are known for their ability to form cormlets, which are small bulbs that grow from the mother bulb. If the conditions are favorable, the cormlets will grow into mature bulbs over time, resulting in an increase in the number of bulbs.
Factors such as proper planting depth, soil moisture, and fertility, as well as adequate sunlight, can influence the rate of multiplication. It's also important to note that some cultivars may be more likely to multiply than others.
Regular maintenance, such as digging up and dividing the bulbs every few years, can also help stimulate multiplication. With proper care and favorable growing conditions, Rik's Frizzle Gladiolus bulbs have the potential to multiply every year.
