Marguerites will stop blooming with the hot weather (except at the coast). Use hedge shears to trim them back, leaving the green stems and foliage (most marguerites won't send out new growth from old growth). For a summer-bloom substitute, try white or yellow lantanas. Unlike marguerites, their flowers will drop off by themselves and do not have to be cut off.
Cymbidiums bloom most when they are a little crowded. If the pseudo-bulbs are pushing the edges of the pot, divide or repot them now to give them a chance to establish spikes. Fertilize with a high-nitrogen growth fertilizer such as 30-10-10. For cattleyas and Phalaenopsis , use a more balanced fertilizer.
Plants in four-inch pots provide instant color and are most abundant in nurseries at this time of year. Pansies, violas, snaps and Iceland poppies will flower for only a short time. For bloom that lasts into the summer and fall, look for vinca, begonias, impatiens and gloriosa daisies. If the roots are matted from confinement in the pot, loosen them before planting.
Pole beans usually require a lot of garden space. However, to get a better-than-
average yield, place an old tire in the garden bed and fill it with a commercial soil mix to which a time-release fertilizer has been added. (That will give the beans a boost.) Anchor a redwood trellis in the center of the tire for the beans to climb on.
