In the northern hemisphere when summer starts it is good to check how well you are garden is prepared for the heat, less rainfall and so on.
Of course, the first thing to check is how well you have mulched – this saves both water and conserves moisture. This also keeps the soil temperature at tolerable levels for the more delicate plants.

Have you sprayed for blackspot on your roses? Keeping this disease under control will ensure healthier plants and better blooming. Feed as buds start to reappear (presuming you have had a spring blooming.
CAMELLIAS AND AZALEAS
These plants initiate their buds during summer for the autumn/winter blooming. They should have been fed by now. Keep the roots cool with good mulching. More on Camellias, more on Azaleas on this site
PLANTS IN POTS
As summer really gets a hold, it pays to make sure you are keeping the pots cool – especially terracotta ones as they soak up the sun’s heat and radiated heat from hard surfaces (paving etc.) Just placing them in saucers really doesn’t work, but is more likely to encourage root rot and be a place for mozzies to breed. You can try and use damp sand in the saucers instead.
While it preferable to have planted your new seedlings before summer gets a grip, if you are only doing them now, sun harden them first – cover with 50% shade cloth or an equivalent until their roots are well established – in some regions you may just need to keep the shade cloth on all summer.
Watering, especially winter rains, can leach away nutrients in the soil – so consider a boost of trace elements for your garden plants.
Gardenias and roses in particular benefit from supplementary magnesium in summer.
See this page for information on the basics: Phosphorus (flowering and fruiting and root growth), Potassium (boosts the plants immune system) and Nitrogen (leaf and stem growth
If you have had a habit of mulching, you shouldn’t need to dig over the garden – mulch should keep the weeds down and the soil friable – that is, well aerated.
These are a great idea – they don’t take up much room and give you loads of fertiliser, chew up kitchen and green waste and provide the worms for your garden and the occasional bird who gets lucky. Keep the worm farm in a shady cool area.
