Understanding Roses' Needs in New Zealand

Creating a Planting Schedule
When planning what to plant under roses in NZ, consider the size and growth habits of both your roses and potential companion plants. Create a planting schedule that allows for gradual growth and expansion, ensuring that companion plants don't outgrow their welcome or compete with your roses for resources.
