\u201cIf I only had one citrus tree to live on for my entire life, this is it,\u201d said our guide through the collection of about 1,000 varieties of citrus selected from around the world. That’s quite a claim. But, coming from Ottillia \u201cToots\u201d Bier, we would be wise to consider it. She has tasted the fruit of hundreds of citrus trees; I\u2019d guess she has experience with as many types of citrus as anyone on the planet.<\/p>\n\n\n\n

We were at a Gold Nugget mandarin tree in the Citrus Variety Collection at the University of California, Riverside. This was the middle of March, 2012. This was my first time tasting a Gold Nugget mandarin.<\/p>\n\n\n\n

I was sufficiently impressed to plant my own.<\/p>\n\n\n\n

Let me tell you more about the fruit and the tree of this variety of mandarin called Gold Nugget in order to help you decide if it is worth planting in your yard.<\/p>\n\n\n\n

<\/div>\n\n\n\n

The Fruit<\/strong><\/p>\n\n\n\n

Compared to other mandarins, Gold Nuggets are medium size — bigger than Kishu<\/a> or Tango<\/a>, smaller than Shasta Gold<\/a> or Shiranui<\/a>. The name Gold Nugget comes from the appearance of the fruit\u2019s rind, which is bumpy and ribbed. Unlike some other mandarins, Gold Nuggets do not have a nipple at the stem end where the fruit attaches to the tree.<\/p>\n\n\n\n

Once Gold Nuggets are mature, you can easily peel them with a single corkscrew motion, popping the pith at the core out of the bottom.<\/p>\n\n\n\n

You would find Kishu or Satsuma<\/a> mandarins even easier to peel than Gold Nuggets, but Gold Nuggets peel easily enough that my two-year-old daughter doesn’t ask me for help.<\/p>\n\n\n\n

As you peel, Gold Nuggets release heaps of aroma and oil from the rind. It\u2019s an intoxicating smell, but it does make your hands messier than with some other mandarins whose peels come off more dryly.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The segments of Gold Nuggets are easily separated, seedless and firm, bursting with juice. The flavor is rich but mostly sweet; it does not have the tang associated with some other mandarins such as Dancy<\/a>.<\/p>\n\n\n\n

<\/div>\n\n\n\n

The Tree<\/strong><\/p>\n\n\n\n

Vigorous is the word that comes to mind when I think of a Gold Nugget tree. Mine was planted at the same time as some of my other citrus trees and it is on the same rootstock and yet it has grown a bit faster.<\/p>\n\n\n\n

This might be in part due to the fact that its fruiting has alternated somewhat. For example, in 2020 we ate a few hundred Gold Nugget mandarins from the five-year-old, five-foot-tall tree, but in 2019 it produced only three, three lonely pieces of fruit. The year prior, it had an abundance of fruit. Here it was in that year, 2018, three years after planting from a five-gallon container:<\/p>\n\n\n\n

Farmers don\u2019t like that Gold Nugget trees tend to alternate bear, and I imagine some home growers wouldn\u2019t like this either. I don\u2019t mind because I have other mandarin trees whose harvest season is at about the same time, such as Pixie<\/a>. But if you are looking for a mandarin that produces fruit more evenly through the years, then Gold Nugget might not be your best bet.<\/p>\n\n\n\n

However, I have found in more recent years that my Gold Nugget tree fruits more consistently, and I think this is because I have been pruning it for size control, which inevitably removes part of the crop each year. <\/p>\n\n\n\n

It is also said by others<\/a> that the alternate bearing of Gold Nugget can be moderated through pruning.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Variety development<\/strong><\/p>\n\n\n\n

We call Gold Nugget a mandarin, but technically it is a mandarin hybrid, as it has some orange in its lineage. In the 1950s, citrus breeders at University of California, Riverside crossed the Wilking mandarin<\/a> with the Kincy mandarin<\/a>, and both of those mandarins are actually mandarin hybrids. Wilking and Kincy both have King tangor<\/a> as a parent, a tangor being a cross between a mandarin (tangerine) and an orange.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Harvest season<\/strong><\/p>\n\n\n\n

Here in March is only the beginning of the Gold Nugget harvest season. We are in inland San Diego County, and our Gold Nuggets start to taste good and peel well from March. (This is late compared to most other mandarin varieties, some of which mature as early as November.) Gold Nuggets will continue to sweeten and peel even more easily through spring and into summer.<\/p>\n\n\n\n

For how long can Gold Nuggets hang on the tree and maintain quality? I\u2019ve eaten some from a tree in Valley Center in San Diego County in September that were still very good. Toots said that she has picked fruit from her own tree in her Huntington Beach yard in October that was still \u201csound and good.\u201d That Gold Nuggets store so well on the tree was a major reason that Toots called it her number one citrus (the other major reason being its outstanding flavor).<\/p>\n\n\n\n

From my own tree, the latest I’ve had good ones is the end of August, but they taste their best around May and June.<\/p>\n\n\n\n

I am only able to keep Gold Nuggets on my tree into May and June if they’re high up or deep inside because my routine is to give my kids the green light to pick from the tree starting at the end of February, on my oldest son’s birthday. This is how the tree looked soon after I let them at it in 2020:<\/p>\n\n\n\n

They wiped out a few hundred mandarins in a month that year. My wife and I enjoyed a relative few.<\/p>\n\n\n\n

Six years later, here in 2026, almost nothing has changed except that the warm winter hastened the Gold Nugget season such that I allowed the kids to pick starting at the beginning of February.<\/p>\n\n\n\n

As you can see by the peels on the ground, they had already eaten many by the time I took this photo on February 12, 2026.<\/figcaption><\/figure>\n\n\n\n

Where to buy a Gold Nugget mandarin tree<\/strong><\/p>\n\n\n\n

They are widely available at retail nurseries and garden centers throughout California. But if you can’t find one nearby, order from Four Winds Growers<\/a>, who makes great citrus trees and can ship a Gold Nugget mandarin tree to your door.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Why Gold Nugget mandarins are becoming less common in grocery stores<\/strong><\/p>\n\n\n\n

Now is a good time to plant your own Gold Nugget mandarin tree because it is getting harder by the day to find the fruit to buy. Anymore, I only notice Gold Nuggets for sale at farmers markets and through the websites of farmers who sell direct, but rarely in mainstream grocery stores.<\/p>\n\n\n\n

I recently learned why. Remember when I mentioned earlier that a Gold Nugget’s rind is both bumpy and releases heaps of aroma and oil when you peel it? These qualities are a problem in the context of large-scale farming and fruit handling.<\/p>\n\n\n\n

The bumps on the Gold Nugget rind are vulnerable to damage during harvest and handling after harvest. The bumps are protrusions that receive concentrated pressure.<\/p>\n\n\n\n

Another mandarin that has a similarly bumpy rind is Shiranui<\/a>, often sold as Dekopon or under the trade name “Sumo.” And so you also find Shiranui mandarins with damaged rinds.<\/p>\n\n\n\n

\"\"<\/a>

But with Gold Nuggets there is the additional factor of higher oil within the rind. When the bumps on the rind receive enough pressure, the cells rupture and the oil is released. The oil is phytotoxic to the surrounding rind tissue and causes brown spots to appear. No one wants to buy mandarins with brown spots all over them.<\/p>\n\n\n\n

Consider how a Gold Nugget mandarin would get from a tree to a grocery store shelf. It is picked and placed in a bin. If it’s on bottom, there can be a lot of pressure from other fruit on top. Then it goes to a packinghouse where it rolls and bounces along “the line” and is cleaned with brushes. Every part of this process can cause rind-cell rupture.<\/p>\n\n\n\n

A long-time citrus harvester and packer told me how Gold Nuggets have to be treated extra carefully in order to prevent rind damage. He said they must be placed in smaller crates holding around 20 pounds of fruit rather than the larger bins that can be used for less delicate mandarin varieties. Then at the packinghouse, the cleaning brushes must have softer bristles and the packing line must be run more slowly, at nearly half the speed as it can be run for less delicate mandarin varieties.<\/p>\n\n\n\n

So citrus farmers, packers, and marketers have been moving away from Gold Nuggets, despite the variety’s unambiguously delicious eating quality inside. It is just straightforward economics. The incentive is, rather, to farm, pack, and sell mandarin varieties that are tougher and therefore cheaper to get from tree to store.<\/p>\n\n\n\n

For example: “The joke is that W. Murcott can be thrown against a wall and it still won’t show damage,” a different citrus packer told me. (W. Murcott Afourer<\/a> is a mandarin variety that is often included in bags sold under trade names like “Cuties.”) <\/p>\n\n\n\n

But hey! None of this matters for a tree in your yard!<\/p>\n\n\n\n
