FAQs
1. What if the arch looks uneven after assembly?
If the arch appears uneven, check that all panels are properly aligned before fully tightening any screws. Sometimes, a slight misalignment during assembly can cause one side to sit higher or lower. Loosen the screws slightly and adjust the panels for better symmetry before tightening them again.
2. Can the garden arch support heavy climbing plants like grapevines or wisteria?
Yes, the Outsunny Garden Arch is designed to support climbing plants such as grapevines, ivy, and morning glories. However, it’s essential to ensure that the plants are not too heavy for the structure. For denser plants like wisteria, it’s a good idea to regularly check the support and reinforce it if necessary.
3. How can I keep the garden arch looking new over time?
Regular maintenance includes cleaning the wood with a damp cloth and applying a wood preservative or sealant to protect it from the elements. If you want to maintain its appearance, consider reapplying varnish every couple of years to keep it weather-resistant and looking fresh.
