Growing Rose of SharonHibiscus syriacus, commonly known as Rose of Sharon, althea or hardy hibiscus is a shrub that is treasured by most, and neglected by many. You'll often see large altheas near homes that may not have been taken care of in years, but it will be blooming as if it was given much time and attention. That is a sign of a hardy, easy to grow shrub!

Rose of Sharon blooms later in the summer than most shrubs, and continues through until mid-autumn. The size of the blooms depend on how you decide to prune it. If it's left to it's own with just an occasional pruning it will have many small blooms, which are lovely and fill the entire shrub during it's peak.

But, a good pruning each spring will keep it more controlled and it will tend to produce less flowers, but they will be much larger. Blooms are in shades of white, pink, purple and red.

Whatever habit you decide to go with, hardy hibiscus prefers full sun and a good soil that is not too dry, or too wet. Average soil in mostly full sun will be ideal. Most varieties will eventually grow to 8-10 tall and about 5 foot wide, depending on pruning.

Rose of Sharon is hardy to about -20 when mature. During the early years mulch well for extra protection. When they are newly planted be sure to water every few days until established.

Rose of Sharon is a beautiful and delightful shrub that will give you years of charming flowers just when you need them in the late summer and fall.

Harvesting and Using Summer Squash

Summer squash is one of my favorite vegetables. I love the yellow summer squash in particular. They should be harvested while still tender, when they have a "glossy" appearance and are still small. You will most likely need to harvest daily once they start to appear.
