Growing everyday plants in dry soil conditions is not easy, hardly ever successful is not sustainable and at the very least will be very time-consuming requiring gallons of water and hours spent watering. This in itself is not Eco friendly and not a long-term solution anyway, as regular watering only encourages the plant's roots to stay shallow instead of going deeper into the ground seeking water for themselves. The plant then becomes dependent on you're watering schedule. Great if you are not on a water meter and have a need to be needed, but not so great if you want to get away for a few days or we have a hosepipe ban.
Why not instead, grow plants that will tolerate dry conditions, the ones nature has designed that way.
Most drought tolerant plants especially the Mediterranean natives, have silver or grey-green leaves to reflect the harsh rays of the sun and some have fine hairs on there leaves or stems, to trap moisture around the plant tissues. They also develop deep root systems that penetrate deep into the ground to reach water reserves.
Selecting plants for planting in dry areas can be easy, if a plant has silver or grey-green leaves that are either woolly or aromatic it will usually thrive in dry soil in full sun. These are a few examples: Lavender, rosemary, santolina, thyme, cistus, sage, phlomis, most achilleas and artemisia.
Plants from hot spots in many other parts of the world have evolved to grow and thrive in dry conditions too and will also survive our dry British summers.
