Use the oils on camellia, hollies, variegated privet, magnolias and gardenias. Oil sprays are safe only when the temperature is below 85 degrees. So, if you miss April, you'll have to wait until late October or early November to apply them. Horticultural oils or summer oils are safer to use during the time of year when warm weather prevails. April is the time to prepare hanging baskets.
Many plants grow well and look good in baskets, but ferns are probably the most highly prized.
They come in a variety of shapes and sizes and are especially attractive in these hanging planters. In April you may plant annual bedding plants as soon as the frost danger has passed. However, you could start your seeds indoors earlier in the month for earlier blooms. New varieties of lantana and verbena would be excellent perennial additions to your landscape. In April you should make cuttings of plants kept inside over the winter, such as begonias, sultana and coleus.
