Questions people ask
- Should I trim the brown tips off?
- Yes, you can trim the brown parts with clean scissors to keep the plant looking tidy. Just be very careful and wear gloves, long sleeves and eye protection, as the sap can cause severe burns and blisters if it touches your skin and is then exposed to sunlight. If sap gets on your skin, wash it with soap and water right away and keep the area out of the sun.
- Does sun exposure cause brown tips?
- Giant Hogweed loves full sun, but if it is extremely hot, the leaves might lose moisture faster than the roots can supply it. Ensure it stays hydrated during peak summer heat.
