No matter how much I like the longer days (getting home when it’s still light!) and warmer weather, I also dread summer a little. While the long, hot, dry days and the coastal breezes may be perfect for a holiday or a day at the beach, they’re not so good for growing anything. The dry summer season is as harsh in its own way as the cold winter of the temperate areas of the northern hemisphere.
The theory is that our forest orchard will be reasonably self-sufficient once established, requiring minimal irrigation or care. That theory has a downside though – it takes years for a forest (or an orchard) to become established. The trees are going in, gradually but steadily, but for their first few years they’ll need a lot of support. Daily watering through summer, wire cages to protect them from rabbits and kangaroos, spraying for insect pests, and more. I’d prefer not to spray for insects, but there is only so much you can do without poison. The guinea fowl seem more interested in eating my hibiscus plants than they do in eating ticks or grasshoppers, and there are too many trees already to hand pick bugs off them all. We have plans to try traps for the grasshoppers this season, half filling bright yellow buckets with molasses-enriched water to attract and drown them, and spreading bran sprayed with a bit of molasses-water around the trees (the grasshoppers & locusts eat this, gum up their digestive systems with it, and die – in theory), but we’re inevitably going to end up spraying as well.
We’ve acquired some Muscovy ducks to free range across the baby orchard as well, in the hopes that they’ll be more motivated to eat bugs than the guinea fowl. I haven’t seen them eating any flies yet, but apparently they do. The surviving juvenile guinea fowl are going to be free ranging soon as well, bringing us up to a total of 6 (4 babies and 2 adults, out of a total of 4 bought as chicks and 18 hatched). They do seem to be keeping the tick population down, but they aren’t having much of an impact ont he grasshoppers.
In the meantime, irrigation is a big ticket item on the to-do list. Last summer we hand-watered every day, carrying 10 L watering cans back and forth. This summer we’re trialling a gravity-fed dripper system, fed from the small water tank, for the apples. It seems to be pretty successful so far, so we’re aiming to put in similar systems (fed from 200 L barrels or 1000 L IBCs of water) for each group of trees. With luck that’ll cut our workload down to weekly check-ups, although it increases the workload now as we get the irrigation set up. There are more trees to go in this autumn, so automated watering systems are essential.
