Rose of Sharon (aka Althea) Hibiscus syriacus Native to China and India, Rose of Sharon was introduced to the gardens of Europe in the 16th century. The specific epithet “syriacus”, refers to it having been collected from gardens in Syria. It is propagated by seed and cuttings, and many new cultivars have shown up in recent years. Many of these cultivars produce little to no seed. Rose of Sharon is a deciduous, multi-trunk woody shrub to small tree that is cold hardy to Zone 5b (-15°F). It tolerates heat, poor [...]

2011 Freeze Update April 1 So many questions!!! Is it dead or alive? Do I cut it back or wait? Should I replace it with something else? Unfortunately, it is impossible to provide a “blanket answer” to these important questions. Each situation is different, and each outcome will also be different. Is it dead or alive?   At this point, if it has not begun leafing out, the best way to evaluate it is to see if the twigs are still flexible. If they snap, cut them down. They may still [...]

2021 Freeze-5 weeks after Thankfully, many plants are beginning to show new growth after being assaulted by record-low temperatures in February. However, we are still not “out of the woods” yet, as some plants may be late to show signs of life. There are many that we KNOW either will not come back or will not come back satisfactorily, so they may be removed/replaced now. I’d also like to remind everyone that although we did get a bit of rain this week, we have been and are currently under drought [...]

One Month After The Freeze It’s hard to believe that it has only been four weeks since Winter Storm Uri graced us with frigid temperatures, ice and snow. We have already had so many warm days that it truly feels like spring! Our landscapes are once again showing signs of new growth. Live Oak trees are pushing out catkins which will be full of pollen soon, and tiny oak leaves are beginning to show.                 Many of our native plants are putting out [...]

I have been getting a lot of questions on whether this plant or that plant will be likely to recover. I think it is important to understand that the plants are still in the process of reacting to this freeze. They aren’t done yet!!! The healthier a plant or tree was going into this freeze, the better the chance of recovery, especially with our native and adaptive species. In the coming weeks or even months, as trees and shrubs that still have the ability to put out new growth begin [...]

Freeze Damage to Plants I am sure everyone is anxious to know what damage the extreme cold temperatures have done to our landscapes. Unfortunately, it is too early to tell in most cases. You will hear me repeat this, I am certain, but “time will tell”. I know it is difficult to have patience, but because there are so many factors that can influence how a plant might be affected, that is exactly what we will have to do. Try to get used to the “ugly landscape”, as we really [...]
