Watering in drought conditions

本周二有读者问我造成的缺水问题花园。William Hill彩票如你所知,这是非常难以保持花园在干旱条件下充分浇水。然而,由于植物只能吸收他们需要为水溶性离子健康成长和成熟作物的养分,水分不足是一个范围广泛的问题,包括病虫害侵袭的原因。

Bare soil in garden beds and around trees, shrubs and vines allows a lot of soil moisture to be lost to evaporation. A 5 cm layer of organic mulch over beds and around larger plants (keeping it a hand span from the trunk) will prevent water applied to the soil from being wasted. Lawns are greedy and as their roots are close to the soil surface, they take water and nutrients intended for fruit trees and favourite ornamentals. Keep lawns beyond the outer canopy of trees and cover the area under trees with mulch.

This is a quick and very efficient way to hand water during drought, water restrictions, heat waves or windy weather. Limp tomato seedlings will freshen up in about 10 minutes after watering by this method.
Simply cut off the base of each container, remove the lids and bury the necks of the containers about 8 cm deep near outer edge of the foliage of plants. Large shrubs may require several containers. Pour water into the container until it begins to drain slowly – an indication that you have dampened the soil in the root area.

Seedlings and pot plants are usually the first to suffer during heat waves, and you can find advice on how to revive stressed pot plants here:Pot plant stress

  1. 缺乏水和炎热的天气是有害的my garden at home. I ‘ll try this tip to save the vegetables I planted. I stopped using chemical fertilizers since it has bad effect on our bodies. I’m growing an all-organic garden. Thanks

  2. A more permanent alternative (for shrubs,trees etc) to the plastic bottle is a length of poly pipe placed in the hole when planting. Size of the pipe will determine the amount of times you need to fill it.
    Thanks, Maria. The polypipe is mentioned in my book (p 162) for this, but I was thought most people have plastic bottles that they can use immediately. – Lyn

  3. In drought, how often do you water? Is it 3 buckets Monday, Wednesday, Friday or everyday? Watering dwarf plants? Is it 1 bucket Sunday, Tuesday and Thursday?
    I don’t know Narelle. Check with your local council for water restrictions in your area.
    Normally, plants are watered when the top cm. of soil is dry.
