Routine lemon tree care, and potato trenches.

I am loving my veggie patch at the moment, but after such a long period of neglect there are a lot of jobs to do.


I think it is a Meyer lemon, but the tag got lost a long time ago. It’s such a good tree, but will need a prune to shape her after this growing season.

Today I spent some time caring for the Grand Lady of our garden: the lemon tree. Our tree produces beautiful sweet juicy lemons, nearly year round. We bought her for our first wedding anniversary, so clearly she is special to us. 3 or so years of neglect have left her nutrient depleted, and suffering several bug afflictions.


Those big lumps are from gall wasp. It was a pretty bad case, and those holes mean the adult wasps have escaped.

My first job was to give her a light pruning. Gall wasp has gotten into several branches, so I pruned them off. Gall wasp causes lumps in the branches, as the wasp lays it’s eggs into the branch itself. These lumps can lead to a reduction in fruit, so I pruned them all off and threw them into the green bin. Pruning is the only real way to control the wasp. I had to chop a few branches that had growing lemons on them too, but if you take them with a little piece of stem attach, they will still ripen nicely.

We also have a bit of citrus leaf miner, some scale and a sooty looking mould. These can all be treated with organic controls, but since none of them are seriously attacking the plant I am on watch and wait alert. A good feed, and some repeated deep watering, might allow the plant to control this herself

Leaving some stem helps the lemons ripen. Baby hands adds some cute factor too.

Next, the girls and I cleared all the grass and weeds from beneath the tree so we could fertilise her. A light hoe got all the growth out pretty easily , and I actually left it piled around the outside to make a little moat. This will stop the water and fertiliser from running down the slope away from the tree.

Lemons need to be fed three times a year: March, July and November (yes, I’m a little late!). I always use a commercial citrus food, but I’m sure you could find some amazing organic options. I choose one with trace elements as well, but you could use rock minerals in combination with a standard NPK fertiliser. There is a dose of fertiliser for lemons, which is 125g per year of plants age. I’m a little less exact than this though, and just toss a couple of handfuls under the tree. It seems to work alright 🙂

Lastly, I mulched with straw from the chicken coop, which provides both manure and soil cover.

Today’s other job was the potatoes. I never buy seed potatoes, as I nearly always have some growing in the potato box anyway. Potatoes are so easy to grow. I wait until a few eyes sprout, then I cut them into pieces, making sure each piece has an eye. I dug a big trench this time, and then planted them into holes at the bottom of each trench. The plants have now sprouted above the top of the trench, so I had to push all the hilled up dirt back into the trench. This will give a better yield then just planting them at ground level (which I’ve done before too). I think next autumn I will do an even deeper ditch, as these plants are doing so well I could use more soil over them.

Tomorrow I will have to start training the unruly beans and peas.

All filled in, and mulched up!
