Double hollyhocks have the potential to spread in a garden. They reproduce by dropping seeds, which can then germinate and grow into new plants. However, the rate of spread can vary depending on various factors such as environmental conditions, care provided, and the specific variety of hollyhocks.
To encourage spreading, it is best to plant double hollyhocks in a sunny location. These plants thrive in full sun and require at least 6 hours of direct sunlight per day. By providing them with the ideal growing conditions, you can help them establish and spread more easily.
When planting double hollyhocks, it is recommended to space the plants about 12 to 18 inches apart. This spacing allows each plant to have enough room to grow and develop without overcrowding. However, keep in mind that as hollyhocks spread through seed dispersal, you may need to provide additional space in the garden to accommodate their natural expansion.
If you want your hollyhocks to fill out the area quickly and create a lush display, it is advisable to allow three to four feet of space between each plant. This wider spacing allows the plants to spread and fill in the gaps within a few years. Additionally, it provides ample space for the hollyhocks to grow tall and showcase their beautiful double blooms.
It’s important to note that hollyhocks are biennials, meaning they have a two-year life cycle. In the first year, they primarily focus on growing foliage and developing a robust root system. The second year is when they produce their spectacular flowers and set seed for future generations.
To encourage self-seeding and natural spread, it is beneficial to allow some of the seed pods to mature and drop their seeds in the garden. These seeds can then germinate and grow into new hollyhock plants the following year. However, if you prefer to control their spread or want to prevent them from taking over other areas of your garden, you can deadhead the spent flowers before the seed pods develop.
Double hollyhocks have the potential to spread in a garden through seed dispersal. By planting them in a sunny location and providing adequate spacing, you can allow them to fill out the area over time. However, it’s essential to consider your garden’s size and your preferences for hollyhock spread before planting them.
