When we first moved into our place about ten years ago, I knew I wanted to grow fruit trees. Our block is not ideally situated for this, in all honesty. It slopes awkwardly, and the front yard is North facing. The soil was very poor limestone. It was planted with eucalypts and palms, with weed matting throughout. The backyard was closely planted with huge conifers and agaves. We paid an arborist to remove the trees and my husband tackled the agaves, and with a blank slate, we planned the garden. Our goal was to have a mix of productive and sensory plants, with the intention to always have something edible to pick from the garden at any time, whether it be herbs, fruits or veggies.
A decade later, we have a large herb, sensory, and veggie garden on rich soil, and about twenty different fruiting trees. In the front garden, this includes a black mulberry tree, which was planted nine years ago.
I love mulberries, but you can’t buy them in the shops. I have fond memories of visiting my friend’s house in the Summer, climbing her huge mulberry tree and sitting up there and searching around, finding the little black jewels. I still like ferreting around the tree, searching around jewel-like fruits to find the black, ripe berries. They look like they belong in a fairy story.
Mulberries are not a commercially viable crop. Picking them takes ages, as the berries ripen at different times. You have to walk slowly around the tree to find the couple of berries per branch ready to pick. They don’t transport well, and the shelf life is not long. So if you want mulberries, you have to grow them. And they are an acquired taste. Not really sweet like commercial berries, mulberries are tart-sweet with an underlying metallic taste that some people do not enjoy.
However, they are hard won. I was not expecting to have much of a crop for the first couple of years, but in the past few years we have waited expectantly for fruit that never came. We have had a couple of dry, tasteless berries each season, then the birds have carried off the rest. Last season, I was despondent, then threatening. I told my husband, “That bloody tree has one more season to produce some fruit, or it’s gone!” Then I thought, as with many garden-related issues, maybe the problem isn’t the tree – maybe it’s the gardener.
It didn’t fill me with joy to admit it, believe me. I don’t want to accept that perhaps I had been neglecting the tree. After all, the apricot tree gave us a bumper crop last year. So did the lime tree. Clearly, I could get a tree to produce fruit. But just as different kids need different parenting techniques, so might different fruit trees. So, I read up on mulberry trees. Any info I could find on mulberries, I consumed. Of course, there were differing opinions. Some said prune. Some said don’t prune. But almost all the experts agreed mulberries needed two things in abundance.
Water and fertiliser. Not so revolutionary after all. Turns out, I had been underwatering and under-feeding the poor tree. I upped the water, which makes a lot of sense on our north-facing hillside (deep water, once a week), and increased the nutrition. From early Spring, I fed the tree with a couple of handfuls of organic fruit tree fertiliser every month around the base of the tree, watered in well.
