Established juniper plants only need to be watered during periods of severe drought.  These plants are fairly drought tolerant, so you should be able to leave them alone during minor droughts. Junipers can actually weaken if you water them too often. Soggy soil and water-logged roots make the plant more susceptible to diseases and pests. Fertilizer should be mixed into the soil around the junipers once in the early spring. Apply fertilizer once more in the late summer.  Use 1/2 lb (225 g) of fertilizer per 100 square feet (9.23 square meters). For best results, apply the fertilizer immediately before an anticipated rainfall. If this is not possible, water the area thoroughly after application. Select a 16-4-8 or 12-4-8 fertilizer. These two types have a large amount of nitrogen (represented by the "16" and "12"), which helps the juniper produce more chlorophyll to grow faster. The phosphorus ("4") is minimal since phosphorus primarily helps with flowering ability. The potassium ("8") is mid-range and helps protect the plant from disease while improving root development. You only need to prune old, dead foliage that builds up underneath creeping juniper varieties. Clearing out dead wood improves air circulation, leading the a healthier plant.  You can also prune the tips of the plant as they bud to limit the height and reach of the plant. If the plant becomes too bushy or dense, you can thin out some of the older wood, as well. Wait until new growth has begun to sprout in the spring before doing any pruning. Since the needles can be painful, you should wear gloves and long sleeves while pruning the plant. Do not do any heavy pruning, however. Not much new growth develops on old wood, so if you cut the wood back to its large limbs, that wood will not grow back and the plant will remain bare. Junipers can develop problems with insects, including bagworms, spider mites, leaf miners, webworms, and aphids.  Most of these pests can be controlled with pesticide. Wait until you see a problem, then purchase a pesticide...

How would you rephrase that briefly using Indonesian?
