Get Your Soil Tested During The Dormant Season

Posted on by

One of the most important needs of plants is good soil for them to grow in. A soil test from the University of Georgia is the most accurate and effective way to assess the nutrient status and the relative acidity of the soil (pH). Applying fertilizer without a test can lead to applying too much or too little lime and fertilizer needed for optimum plant growth. To collect the soil, take a minimum of ten samples randomly in the area that requires testing and mix the soil thoroughly in a container, like a bucket. Bring two cups of the soil to the Extension office for testing. You will then place the soil in a small bag, and fill out some information on the side of it. For a fee of $8.00 per sample, the Extension office will mail it to the University of Georgia Soil Testing Laboratory with the results…

Scented Geraniums: A Worthy Addition To The Home Garden

Posted on by

Scented geraniums (Pelargonium species) are excellent herbs to grow in the garden. They are tender perennials and are planted in containers so that they can be easily brought in for the winter. These plants are treated as annuals, but have been known to survive the winter if mulched and the temperatures do not get too cold. They are grown for their scented leaves, not for their flowers like traditional geraniums. Scented geraniums come in all shapes, sizes, and colors. Some have highly aromatic foliage. Some varieties have bright red flowers, while others vary from white to pink. Their leaves range from rounded to finely cut. The leaves can be dried and used in potpourris or added to teas. They should be grown in well-drained soil and in full sun. However, during the hot part of the day, they need some shade to keep from being scorched. The smaller leafed varieties…

Azaleas For The Southern Garden

Posted on by

There are over 900 species of azaleas (Rhododendron spp.) and over 8000 recognized hybrids. Azaleas belong to the Ericaceae family (the heath family which includes blueberries and mountain laurels) and are used extensively by gardeners. These plants freely hybridize and there are new cultivars introduced every year. Gardeners should seek out the new cultivars to add excitement to the spring garden. The azalea is found all over the world but most notable horticultural species are indigenous to Japan, China, and the United States. In the US, native azaleas are found in the Pacific Northwest and the Southeastern US. Most azaleas grown by home gardeners are the Asian evergreen varieties, although the native deciduous Piedmont Azalea is still prized by many. The plant’s beautiful blooms and stout character has earned it a place in most American gardens. The azalea is a favorite of gardeners and is grown by the millions in…
