Growing Citrus Plants in Mosgiel

Hello friends,

Some of my favorite fruits of all time to grow are citrus. I love growing lemon, limes, and mandarin bushes, not only for their fruit, which I love using in food and drink all year round, but also for their shiny bright foliage which looks great when the plants are grown in a patio setting.

Back when we lived in Tawa, Wellington, I was able to grow lemon, limes, and mandarin plants outdoors throughout the year in the ground at our hillside home, and only had to protect them from frost for about ten nights each year. When we moved back to Mosgiel, in Dunedin in October 2019, however, I knew I had to make a decision on how to grow my citrus plants. From previous history, I knew that I couldn't just plant them in the ground and leave them to fend for themselves in Dunedin's winters.

The suburb of Mosgiel where we now live is blessed with its own microclimate which is far different from that of the rest of Dunedin, as it lies inland, in a sheltered valley 6 km from the sea. In summer Mosgiel is warmer and sunnier than Dunedin, and in winter is is colder and frostier. I love this about Mosgiel because it is more like Central Otago/the Mediterranean, than the rest of Dunedin, which nearly always get cool sea breezes from either the south-west or the east.

Warm, sunny summers are great for citrus plants, but cold and frosty temperatures in winter, along with the occasional snow, are not, especially when temperatures drop down to -6˚C. So I decided to put my citrus plants into very large plastic terracotta-like pots so that I could shift outside to our patio in late spring, and then bring them into our glasshouse in autumn for protection over the winter months. I also chose to plant the most cold hardy varieties that I could find, to give the plants their best chance at life.

The first citrus plant chosen is the lemon variety Lemon Meyer. It is the hardiest of all lemon varieties, is a heavy cropper, and the juice from the lemon isn't too sour. It was the first citrus plant I planted. It has flourished in it's position in the patio during the summer months, and now bears many fruit each year.

The second citrus plant chosen is the lime variety Tahitian Lime. We mostly use limes in our favorite soup recipe, Tomato, Capsicum and Lime soup, and this variety works perfectly for our needs. As limes do not like the cold at all, we were very surprised to see it growing and flourishing over the last three years. The first year we had two limes, and now each year we are getting dozens of limes off the bush, so many in fact that we are now giving our excess away.

The last citrus plant we chose was the Satuma Mandarin variety. Mandarins are one of my favorite fruits (much easier to peel than oranges), and are the perfect size for snacking on. They went into our last citrus pot, and along with the lemon and lime plants, they grew healthy and strong during it's first and subsequent summers. I am currently awaiting on it's first harvest, hopefully I can eat some soon.

Each year, at the beginning of October, they are moved out of our glasshouse, and into our patio, where we have just enough space for the growing plants. Over the spring and summer they are fed both a monthly and long term fertiliser, and are watered nearly every day to ensure the pots don't dry out. I recently also added Ecowitt Soil Moisture sensors to each pot to keep an eye on their moisture levels, so I know exactly how each plant is faring, and if they need to be watered.

They stay there all summer long until the end of March, and then we drag them back into the glasshouse for the winter.

Because of the many cold and frosty days ahead I take a multiple layered approach to keeping them healthy over winter. The first is to keep them safe in the glasshouse over winter, which keeps them safe from high wind damage and protects them from small frosts.

The second layer of protection is the use of Vaporgard Liquid frost cloth. It is an organic wax made from pine resin which helps protects leaves from frost damage down to -3˚C for 2 to 3 months. I usually spray my citrus plants with Vaporgard twice over winter in the glasshouse, and once more when they go outside in early October, since we sometimes get late frosts even up to the end of October. The good thing about Vaporgard is that it can also be used in summer to slow down moisture loss from plants.

The last layer of frost protection is my ever trusty frost cloth. I have a container full of it which I drag out of the shed each autumn. I usually drape a single layer over the citrus plants on frosty nights, but if I know that a big cold snap with snow, or a prolonged period of frosty weather is about to happen, I double up the frost cloth layers. On frosty mornings I don't unwrap the citrus plants from their frost cloth layers until the glasshouse has defrosted in the sun.

This multilayered approach to frost protection has worked really well with my citrus plants until now, but now I have a problem. My citrus plants have outgrown their pots, and they have gotten too big to transport to and from the glasshouse each winter. I need to find space in the garden for them to grow and flourish, and this means I have to plant them into soil. They are in the glasshouse for the last time this winter, and come this spring, they will be planted into the ground.

This means I am currently undertaking a winter garden project to rearrange the sunniest and warmest part of our garden to fit the citrus plants into this coming spring. And then after this summer and autumn I will be undertaking another project to figure out how to protect the citrus from frosts the next winter after that.

It's a big winter garden project at the moment, but it'll be worth it once the plants are happy, and thriving, and give me much more citrus to eat and drink in the coming years.

Have a wonderful day

This Year's Feijoa Harvest

Hello friends,

This year's feijoa harvest is finally over.

When we first moved back to Dunedin in October 2019, one of the first things I did in the garden was to plant two feijoa plants side by side in the backyard. I chose the varieties Unique and Wiki Tu from Waimea Nurseries, because the shrubs were smaller in final size, bore prolific fruit, and their staggered fruiting harvests would give us a long season lasting from early to late autumn. I positioned them in a sunny but sheltered position on the back fence line, so the surrounding trees and shrubs would protect the plants from winter frosts.

The first season I only got two fruit, the next, about twenty, and now in our latest season we got at least one hundred.

There was quite a big difference in the size of feijoa depending on the varieties. The Unique variety is on the left of the photo below, and the Wiki Tu variety is on the right. The Wiki Tu variety harvest started in March with huge fruit as big as my palm, and the smaller Unique variety wasn't ready to harvest until May. This is quite amusing considering the variety notes show that the Unique variety should be ready in March, and the Wiki Tu variety should be ready in May...

Overall it didn't matter too much, and pretty soon in March we were inundated with feijoa fruit. The first harvests of feijoa were frozen away for later use, with the skins set aside to make feijoa syrup (which I'm yet to do), and the pulp set aside to make one of our favorite recipe's, Feijoa and Coconut cake.

With our freezer stocked up, we began to give away feijoa to friends and family. Luckily since there aren't that many feijoa bushes in Dunedin (the plants don't like the cold, so there aren't feijoa bushes in every backyard like they are in the North Island), soon our bounty was soon carried off to other peoples homes. Even then the feijoa harvests kept on coming. And after hearing that my young nephew was unsuccessfully trying to make his own feijoa jam by mashing feijoa pulp with sugar in a bowl, I decided to make a batch for him, and the wider family too.

I used the feijoa jam recipe from the Chelsea sugar website, and I'm really happy with the result. The addition of lemon zest and juice really gave the jam a nice zing that my whole family liked when they tried it.

And even after all that, the feijoa still kept on once again we gave left over feijoa to family members. I don't really mind that we started giving away so many, as my feijoa loving family would otherwise be spending up to $10 a kg buying them, and with very hungry nephews and nieces, the expensive feijoa fruit wouldn't last very long. All I hope though, is that in the coming years, they will continue to help us out with the no doubt increasingly larger and larger feijoa harvests... 

Have a wonderful day

Our Poached Quince Recipe

Hello friends,

Today I thought I'd share our poached quince recipe with you. It's the perfect autumnal dessert to eat with vanilla ice cream on a cool night. And if you have any poached quince left over, just freeze it away to eat at a later date. Quinces are an acquired taste, just like feijoas, but once you've tried them, their wonderful aromatic taste will stay with you all year, as you impatiently wait for their autumn harvest once again.

The hardest part of the recipe, is probably finding quinces. When we lived in Wellington our local New World stocked them for a few weeks each autumn, so we bought them when we could, and made up a big batch to last us over the year. Now we live back home in Dunedin, it's a bit harder to find quinces, as local shops don't stock them. Luckily this year, I had an excess of pumpkins, and I swapped a big crown gray pumpkin for a box of quinces with an online friend, but this excess pumpkin harvest swapping adventure is a whole other story.

For this recipe you'll need:

3 - 4 ripe quinces

750 mL of water

1.5 cups of sugar

1 cinnamon stick

1 vanilla pod (or 1 - 2 star anise if you can't get a vanilla pod)

The recipe:

1. Peel and core the quinces, chopping off any damaged sections. The fruit are quite brittle and hard, so it's a bit of a job to do. The fruit are unpleasant to eat raw, so I wouldn't advise trying it.

2. Chop the quinces into slices or cubes depending on how you'll want to eat them. The fruit will start to oxidise quickly (turn brownish), but don't worry about that, it'll all turn out okay in the end.

3. To a pot add the water and sugar, mix, and begin to heat to a simmer.

4. Add the quinces to the pot, and add the cinnamon stick and vanilla pod. You can swap out the vanilla pod for star anise if you want, but personally I prefer the vanilla pod.

5. The next thing to do is to make a paper cartouche for the quince mixture. A cartouche is a parchment paper lid, and it covers the surface of the poaching mixture. It traps the steam, and keeps the components submerged in liquid. We just cut off a section of grease proof paper, and folded it so it fitted on top of the quince mixture. It is important to mold it to the mixture so it keeps everything wet.

6. With the lid of the pot off, heat the mixture up, and then let it simmer for an hour. Over time the quinces will slowly change colour, changing from a creamy yellow, to a dark rose pink. This is the colour at the 30 minute mark, it hasn't changed to a pink shade yet.

7. This is the colour at the 60 minute mark. The quinces now are a rose pink, but not quite dark enough. If you do a taste test you'll find them still slightly bitter, but the quinces will be soft like cooked apples.

8. What you are looking for is a slightly darker shade of rose pink, and the quinces will taste highly aromatic. When you're happy with the flavor and taste, remove the cinnamon stick and vanilla pod (or star anise) from the mixture. Remove the pot from the heat.

9. The only thing left to do is eat it, storing any left overs in the fridge or freezer. I recommend having it while still warm (or re-heating in the microwave), with some good quality vanilla ice cream. The vanilla ice cream really brings out the aromatic quince flavor.

I hope you get a chance making our poached quince recipe yourself over the autumn season, they really are a wonderful fruit. We currently have a fresh batch stored in the fridge to eat this week, and also a couple of frozen batches stored away for later on in autumn and winter.

Please let me know if you give this recipe a go, and tell me what you think of it.

Have a wonderful day.
