Gardening tips, gardening info and heaps of ideas to help gardeners of all experience get more out of their hobby and out of their gardens.

Most home gardeners buy garden canopies to add some shade into their yards. They erect them over the deck, patio or paved area hoping to flee from the boiling sun that threatens to malign their sensitive skin. With shade overhead, the sun no longer has its bite and people can sit all day under these canopies without being seared to death.
Yet the obvious benefit of a garden canopy is also its downfall. Shade = no sunlight. While this may good for the purpose a canopy was intended invariably we forget to pull them down once we no longer need them. A day or two ...or three... months passes and before you can blame the kids for leaving it up the lawn has now perished due to lack of sunlight and the plants subjected to its cover appear impoverished and neglected.
You stop and consider your predicament realising that while shade is good for you and your family, your plants and garden aren't as wildly positive about it. In fact, as you soon realise, they suffer because of it.
Garden canopies are intended to be erected for short periods of time - for example, the weekend at most. But, human nature being what it is we often forget to dismantle them until the next gale force weather warning interrupts our TV viewing.
So how can garden canopies co-exist with the garden?
I'm glad you asked. Understanding our own human laziness when it comes to erecting/dismantling a canopy we have to explore other avenues. Putting it up and pulling it down every time you want to spend some time relaxing in the garden is not a plausible option.
Instead, try achieving one of these options:
With a few rules in place, summer and garden canopies can co-exist and your garden won't struggle from the increased shade.

Over November/December, all of my veges (including pumpkins) really suffered under the hot Perth sun, some completely died over a few hot days.
So I put two of these covers up over my vege patches and now the plants are growing strongly. Even the nearby grass seems to be surviving better now.
They get morning and afternoon sun, and that seems to be enough. I think the idea that plants need "full sun" in the Perth region needs to be readdressed by the experts, because it seems like too much of a good thing for my plants.

Paul, there are a few variables which you haven't made known here so I'm going to make some assumptions - 1) that your soil is predominantly a sandy loam so water quickly leeches through it, and 2) Perth is going through some tight water restrictions at the moment.
These two assumed variables will easily make your veggies suffer under full-sun so in your case, covering them during the extremes with a garden canopy makes a lot of sense.

Hi Stuart,
Yes my dirt is mostly sand, plus whatever soil improvers, compost, manure that I've put in. Plus mulch on top.
The bigger problem I seem to have is that the water doesn't get through at all. I put on wettasoil etc, that helps. But eg for the grass, in a few weeks its back to being waterproof and if I don't do anything, it dies.
I have one patch of grass which had turned near-white and dry. I put wettasoil, seaweed, etc on the whole patch and then a bit later put up a shadesail that happened to shade half of that patch.
Now the shaded portion is partially green, and the unshaded bit is still almost completely dead.
Not sure what to do except keep putting up shade, and take it down around April I guess.
