Climate change has affected farmers and gardeners all over the globe with the winters being dryer and most places being in a full on drought.
South Africa has struggled with a drought for quite some time. Luckily Nigel Colborn told the Daily Mail that there is a lot gardeners can do to minimise the effects of a drought.
Here are Colborns tips below;
What to buy
If you are still buying plants, go for drought-beaters. Petunias, portulacas, tagetes, pelargoniums, marigolds and succulents cope with dry conditions. Mix moisture-conserving gel into your compost or buy compost with moisture-holding additives. Don’t increase feeding — that causes greater stress. And, if you have to ration your water, halve feeding until supplies return to normal.
Beds and Borders
If you can water with a hose, do so in mornings or evenings. Reduce evaporation by using porous hose or trickle-tubes, rather than sprinklers. Lay mulch to conserve moisture.
Grass and Lawns
Don’t worry when grass turns brown in drought. Raise your mower blades a notch or two and don’t apply fertiliser. When rain returns, keep those blades high until the grass has recovered. Groomed lawns are thirsty and environmentally unfriendly. Consider converting to a flowery meadow. My tiny lawn is droughtstressed but still flower-strewn and beautiful.
Give priority to maturing crops — strawberries, raspberries, salads, potatoes. Keep winter crops such as brassicas alive but ration them. Don’t sow winter carrots until the drought breaks. You have until July.
Shrubs and Trees
Mature plants will cope with adverse weather. But rhododendrons and azaleas may need watering. Newly planted shrubs or trees need regular watering.
Water plants in the morning or evening. Water containers thoroughly and wait until the compost is almost dry before watering again. Use water butts to gather rainwater from roofs.
You’ll be surprised at how quickly they fill. Bath, shower or washing-up water is fine for plants. And you can use ‘grey’ water from dishwashers if you can gather it from the drain pipes. The RHS recommends using grey water within 24 hours to avoid bacterial growth.
Mild contamination of soils by soap should not be a problem if the water is used in moderation. Softened water is less desirable. It might help in emergencies but long term use will cause a build-up of salt in the soil. When it finally rains, we’re not out of trouble.
Half a day’s downfall may bring only short-term relief. Soil moisture deficits will need regular rain to replenish, so keep saving water.
Climate change is likely to result in more frequent droughts. So it’s wise to adjust your planting over time. There are many gorgeous drought-proof plants. These include euphorbias, crambes, verbascums, verbenas, pearl everlasting, pinks and more.
Succulents could be used more, too. I’ve started collecting echeverias, aeoniums and aloes. They don’t care if rains but in drought, they may be the only plants to stay pretty.
