New Citrus: Key Lime.

Well i finally caved and brought a Key Lime tree today. I had tried to resist the urge as i already have way too many Lime trees already (6x Tahitian, 2x Australian Fingerlime, 1x Kusaie, 2x Kaffir). But i have been reading through the Gardenweb forums lately, and from what a lot of the members there say it is the best flavoured of the Limes compared to a Tahitian. Funnily enough, even with all my Lime trees, i have run out of Limes at the moment! (this is how i have justified the purchase). Must be time to ease up on the cocktails LOL.

Key Limes are smaller and seedier, with a higher acidity, a stronger aroma, and a thinner rind, than that of the Tahitian lime. It is valued for its unique flavor compared to other limes. 

The peel is thin, smooth and leathery, and greenish yellow to yellow at maturity. The pulp is greenish yellow, juicy, and highly acid with a distinctive aroma. They are quite seedy, which are highly polyembryonic (two or more plants identical to the mother plant may be produced from one seed). The name comes from its association with the Florida Keys, where it is best known as the flavouring ingredient in Key lime pie. (Here's my recipe for Key Lime Pie). It is also known as West Indian lime, bartender’s lime, or Mexican lime.

Key Lime is a small, bushy tree that will grow to around 5 metres when fully mature. Its trunk, which rarely grows straight, has many branches, which often originate quite far down on the trunk.  It has slender branches armed with short to medium length thorns.  The leaves are small (
3-9cm long) & ovate, resembling orange leaves (the scientific name Citrus Aurantiifolia refers to this resemblance to the leaves of the orange, Citrus Aurantium). The flowers are 2.5 cm in diameter, are yellowish white with a light purple tinge on the margins. Flowers and fruit appear throughout the year, but are most abundant from May to September in the Northern Hemisphere.


There are various ways to cultivate Key limes. This variety of citrus can be propagated from seed and will grow true to the parent. Alternatively budwood can be grafted onto rough lemon or sour orange rootstock. The method of cultivation greatly affects the size and timeliness of the harvest. Trees cultivated from seedlings take 4–8 years before producing a harvest. They attain their maximal yield at about 10 years of age. Trees produced from grafting or 
cuttings bear fruit much sooner, sometimes producing fruit (though not a serious harvest) a year after planting. It takes approximately 9 months from the blossom to the fruit. When the fruit have grown to harvesting size and begin to turn yellow they are then picked.

The Key lime tree does best in sunny sites, well-drained soils, good air circulation, and protection from cold wind.
Generally, Key lime trees need only limited pruning. Prune only to shape trees, to remove dead wood, to limit tree height & maximise the circulation of air.

How to make Lemon Curd.

There's something about Lemon Curd that makes it so luscious, so delicious. Its a magical mixture of tart Lemonyness, sweet Sugar & creamy Egg yolks that makes it like the Chocolate of Citrus lovers, the ultimate for any Citrus Enthusiast. Made by gently cooking a mixture of fresh Lemon juice, Sugar, Butter & Eggs until thickened, its simplicity makes it even more attractive. Lemon Curd is divine on buttered toast, a simple and perfect way to appreciate the curd's cool, satiny texture. It also makes an easy and delicious filling for tarts, cakes & desserts. Its tart Lemon flavour makes it a great ingredient to balance the spiciness or the richness of other ingredients. Pair it with a Scone or slice of Toast and you'll appreciate how Lemon Curd can transform a simple, somewhat homely item into something wonderful.

Lemon Curd Recipe

250ml fresh Lemon juice, finely grated zest.

5 Whole Eggs

500gm Caster Sugar

100gm Butter, cut into small cubes.

  1. Put the Lemon zest and juice, the Sugar and the Butter into a heatproof mixing bowl. Sit the bowl over a pan of gently simmering water, making sure the water is not touching the bottom of the bowl. Stir the mixture every now and again until all of the butter has melted.
  2. Lightly whisk the Eggs and stir them into the Lemon mixture. Whisk until all of the ingredients are well combined, then leave to cook for 10-20mins. Be careful that it doesn’t curdle by making sure the temperature remains constant, and it doesn’t get too hot. Stir regularly until the mixture is creamy and thick enough to coat the back of a spoon.
  3. Remove the Lemon Curd from the heat and set aside to cool, stirring occasionally as it cools. Once cooled, spoon the Lemon Curd into sterilised jars and seal. Keep in the fridge until ready to use. It will keep (refrigerated) for 1 month.

Spring Blossoms!

Well its officially Spring! Finally we have made it through the drudgery that is winter. Though the wind, rain & cold still didn't stop us achieving quite a lot of new plantings and enhancements throughout the garden. We put in a new deck for our daily Sundowner, a new Lavender farm of over 60 plants and many new fruit trees and natives. These were all planted in mid-winter with the hope they will be well rooted by the time the dry, parched Summer comes.
With Spring comes the sweet bounty of fruit blossoms and the blossoms of Citrus have to be the most intoxicating of them all. If the flower itself wasn't enough, the perfume they exude is the icing on the cake (especially Oranges).



I usually try to make sure my fruit trees are well fertilised in anticipation of the new growth & flowering that comes in Spring. Early August is a good time to make sure to spread a good Fruit Tree/Citrus fertiliser and even some extra Potash to aid flowering & fruiting. Then when things start to warm up in Spring the plants are all ready to push out their new growth & produce fruit. It is also a good time to spray Copper on the Stonefruits to prevent Peach Leaf Curl. 

Peach Blossom
Spring also heralds the start of the growing season especially for the Vege Patch so I'm also starting to plan what i will be growing this year in there. I will definitely be planting Tomatoes, as far as varieties go i love Cherry Tomatoes so i will plant one red, one yellow teardrop and one black striped Cherries. I also love the Mexican heirloom tomatoes such as Zapotec and other Oaxacan beefsteak varieties that are big, colourful with fluted ribbing and most importantly beautiful flavour. I will also plant three varieties of Courgette, Tomatillos, Jalepenos, Habaneros, Coriander, Basil, Lebanese Cucumbers and Corn. With these i will use them mostly for my mexican-inspired recipes which really shine during summer. For some of my recipes check out my book called 'Viva La Mexico' its available for free download as an e-book at

Tomatillo harvest.

My favourite Summer recipe though has to be my Caprese Salad. Nothing beats a late afternoon Sundowner and then munching this one down with a glass of Rose. Here's the recipe:

Caprese Salad.

Buffalo Mozzarella or Bocconcini.

Ripe Tomatoes.

Basil Leaves.

Extra-Virgin Olive Oil.

Maldon Sea Salt.


1. Slice Mozzarella & Tomatoes into thick, round slices.
2. Pluck whole leaves of Basil.
3. Layer Basil, Tomato & Mozzarella around in a circle.
4. Place a sprig of Basil in the centre.
5. Drizzle well with a good Olive Oil & sprinkle with Salt & Pepper

Objects of Desire: Sumo/Dekopon

The Sumo is an exciting new hybrid of Citrus with an interesting story. Sadly it is yet to come to NZ in either fruit or tree form but i am very eager to try. From all accounts though, it seems to be a prized fruit at the high end of the Citrus market.

Its story begins in 1972 on Kyushu Island in Japan. A citrus grower there set out to develop a fruit which would combine the best of the easy-to-peel Japanese Satsuma with the big, juicy, sweet oranges from California. It is specifically a hybrid between a Kiyomi Tangor and a PonkanAlthough he saw promise in an obscure tangerine-orange hybrid, this new fruit was challenging to grow. Thankfully, the grower persevered. Over time, he developed a series of methods for growing, pruning and thinning his trees, which is different from all other citrus.
It took over 30 years but his hard work was rewarded when recently, this new variety became the most prized citrus fruit in Japan and Korea.  Following the Japanese tradition of offering the best fruit as a gift, one can find it in Tokyo gift shops, selling for up to US$10 for a single piece of fruit!  Now this legendary fruit, which is called Dekopon in Japan and Hallabong in Korea, is available in America.
Sumo is the biggest mandarin you'll ever seen. It has a distinctive shape with a prominent "top-knot" or large protruding bump on the top of the fruit. The peel is bright orange, bumpy and loose so it peels effortlessly, usually all in one piece! The delicate sections separate easily. Sumo has very little albedo (the white part of citrus), allowing the fruit to section easily with less of the white "netting" sticking to the fruit. It is avalible in stores in very limited supplies available from February-May in the U.S. It's seedless, juicy without being messy, and one of the sweetest of all citrus with very low acid.
At the beginning of the harvest, the fruit is very high in acidity. Consequently growers use a secret Japanese storage method to "cure" the fruit, to reduce its tartness. But with full maturity, after the three weeks curing in vinyl pouches, sugar rises and acidity drops naturally. Dekopons measured 13-18 degrees Brix (a measure of sugar content), numbers that mean powerhouse flavor. (Typically, other commercial citrus varieties such as navel oranges and clementines average 11 to 13 degrees.)
Hopefully this variety will become available soon in NZ. It has only just been released in the US in the past year under the name Shiranui after much cloak & dagger with budwood quarantine procedures from Japan. The Citrus nurserys here i've talked to haven't heard of it yet and have mentioned it is quite difficult to import new budwood into NZ.
