In dry countries such as Australia, water is almost always a concern. Plants with similar water needs should be grouped together. Organic matter in soil, mulch and water crystals can slow water loss, and self-watering pots can also stop water from drying out. Water should be considered even before planting; watering the day before planting as well as planting early in the morning are both advisable. It is best to water plants, even shallow-rooted herbs, thoroughly on an occasional basis than it is to sprinkle them every day. Watering in the morning can both keep them going all day while preventing fungus from growing overnight. Additionally, trees should be kept within 3 metres of height and width, with compact, thicker growth. Drought-tolerant fruits, which require less water, include figs, pomegranates, olives, grapes and mulberries. Vegetables that are productive for their water use are tomatoes, beans, cucumbers, squash, eggplants, capsicum (bell pepper), zucchini and pumpkins. Herbs with low water requirements include rosemary, thyme, sage, lavender and oregano.
