Watering early in the morning allows less water to be lost Bulbs/Corms through evaporation, Certain plants develop fungi, if watered at night, e.g. mildew on roses and zinnias or rust on lawns,Most bulbs/corms are suitable.Some of the more hardy bulbs/corms are: Watsonias, A PROPERLY DESIGNED irrigation system could save up to 30%Chinkerinchee and Knysna lily (Cytanthus), Moreas, Amaryllis, of water used. Always override your irrigation system if it rains.Freesias, Ixias, etc. Several Agapanthus species although not Encourage deep roots by watering for longer periods but lessbulbs are drought-tolerant and make excellent ground covers. often. This applies particularly to lawns. Saving water is a way of life Annuals ConclusionVery few annual plants can survive drought for long periods, It is important to realise that a water-wise garden planted now, Creating abut with MULCHING, and careful selection of the many varietiesavailable, one can have a very good display, will continue to yield benefits not only in the immediate years, but 40 or 50 years hence, when water scarcity will be even water-efficient more severe. garden Ground preparation The challenge to us all is the optimal use of water in our gardens as a way of life and the most effective means to this end is toMulching and composting have the following benefits: avail ourselves of the enormous floral wealth of indigenous plants available here in the Western Cape. conserves soil moisture and reduces evaporation of water prevents soil erosion and run-off and retains maximum water Saving water is a way of life reduces weed growth and thereby saves water absorbs heat and keeps the soil cool beneath reduces the fluctuation in temperature improves the soil condition and nutrients during compost decomposureStraw, bark chips, gravel, pebbles, exposed aggregate, nut shellsand leaves are other materials which can be used for mulching.Soil water retention is vitally important to a plant’s ability toutilise water. Try using a soil-wetting agent to help the soil retainand absorb the water which is applied to it. WateringGrey water or the water one discards in the home is oftenwasted, instead of used in the garden. Many people havedevised ways of catching bathwater and rainwater whichcan be recycled and used in the garden.During water restrictions people are only permitted to waterthe garden on a specified day (depending upon the level ofrestriction), before 10:00 in the morning or after 17:00 inthe evening.
