What are some of the features of the plant commonly known as the "knockout"?
The "knockout" is virtually disease-free, with no black spot, rust, or mildew, and adapts well to less than ideal soils. It has stunning foliage, never needs pruning, and it flowers for months from early spring to fall.
What is a good companion plant for roses at the entrance of a bed?
A pair of ornamental grasses such as Miscanthus, specifically a variety known as "morning light," which matures at about 3 feet or so, is a good choice to soften the entrance without overpowering it.
How can you naturally prevent weeds that have sprouted in mulch?
You can remove newly sprouted weeds and seedlings by dragging a steel garden rake through the mulch. This also helps to fluff the mulch, bringing back its color, and allows water to percolate more easily into the soil.
Why might an azalea's foliage turn yellow even in an ideal location, and what is the solution?
The yellowing foliage of an azalea may indicate a soil pH problem. Azaleas require acidic soil, and if they're planted near alkaline materials like limestone or brick, you might need to add soil sulfur to lower the pH to an ideal level, along with an all-natural fertilizer like alfalfa meal.
What should you look for when selecting plumeria cuttings, and how do you grow them?
When selecting plumeria cuttings, make sure they're firm from top to bottom and the cut portion has calloused over. Plant them in sterile potting mix, sand, or vermiculite, water well, and place in a spot that gets at least a half day of sun. Leaves should begin to emerge from the tips within about four weeks, indicating root formation.
What are some types of Holly, and do they produce berries?
Hollies can be deciduous or evergreen, and some common ones include the American Holly, English Holly, and winter berry varietals. Male hollies won't produce berries, but female hollies will, often with vibrant red or orange berries. Variegated Hollies may have foliage that is as attractive as the berries.
How do you propagate Holly plants?
Holly plants can be propagated via seed, cuttings, or grafting. For seed propagation, pulp and chemicals inhibiting germination must be removed by rinsing the seeds, which are then planted. For cuttings, select a vigorous shoot during summer or late fall, dip it in a rooting hormone, and place it in a potting flat. They can also be grafted, a method usually reserved for more experienced gardeners.
