I bought a Mallow Hibiscus, just about 3 weeks ago. I read on the Internet that they like lots of water. I made sure I watered it at 8am when I went to work and again, around 8 at night to make sure it had plenty, but it is turning all brown Can you give me any suggestions? I have it in front of my house, that gets all day sun, it that the problem? When I bought it, I noticed you had it in front so I thought that would be ok Marlyn
Marlyn, Mallow hibiscus do indeed enjoy full sun. While you need to make sure that the soil stays constantly moist it is possible that you’ve been giving it too much water and the roots are drowning. Soaking it morning and night will create soil that is “soggy wet” not ‘constantly moist’ as is recommended for Mallow Hibiscus. Back off on the watering….you’re drowning the plant! Before you water again, poke your finger into the soil to a depth of 4″ to 5″. If the soil is cool and slightly moist, don’t water. Check again a couple of days later. Only when the soil at 5″ is dry should you water. Soak it thoroughly then check it again after four days or so. Never, never spray the plant with water but soak the soil below to keep the leaves dry and healthy. More on that here: See Wise Watering Without Waste http://ourgarden.freedomblogging.com/ You might remove any really brown leaves so it will grow some new fresh one to replace them. Feed them a high phosphorus liquid plant food like Blooms Plus or Jack’s Classic every fourth or fifth watering to help with the recovery. In spring, your Mallow Hibiscus won’t show any sign of life before the Lilac are blooming or even later. Be patient, they’ll be along. Peter Bowden
