Growing Guide – Sun Sugar Tomatoes

Sun Sugar Tomatoes

As most of you know I am a graduate of the USU Master Gardener program.  I learned a lot from the classes and made some great new friends.  But if I gained nothing else from the program, the discovery of Sun Sugar Tomatoes would have made it all worth while!!!  Back in 2011 when I was taking the classes all of my new gardening friends were raving about this new cherry tomato so I took them up on the offer and started growing them that year.  We have grown them now for 4 seasons and will never go back to “regular” cherry tomatoes.

Sun Sugar Tomatoes are a cherry sized tomato.  They ripen to a very nice orange color.  They are  bit bigger than the traditional cherry tomatoes that I have grown in the past (Sweeties and sweet 100’s).   I have also found that they are overall more productive than many of the more traditional cherry tomatoes.  They are also very early to mature.  These are always the first tomato in our garden.  The are also fairly hardy and make a good choice to plant extra early in a wall of water.  We have grown them in walls of water for 3 years now and a mid April planting will mean you have tomatoes by mid to late June!

This is no ordinary cherry tomato!  They are bursting with sweet delicious tomato flavor.  These are seriously the best tasting cherry tomatoes I have ever eaten.  They are like eating tomato flavored candy!!  Valerie loves cherry tomatoes and eats them by the bucket full in August and September, but I have never been a real big fan of them.  I’ve never been one to just eat a plain tomato.  I usually prefer my tomatoes in a recipe or at least a sandwich or salad.  But Sun Sugar Tomatoes have changed that for me, just  writing about them makes my mouth water!!

I started my first season off with 2 starts.  Two of my Master Gardener friends each gave me a start to try.  One of them met an early demise when it had an accident involving and soccer ball and a trampoline (don’t ask).  The other survived to maturity and after struggling to set fruit through our hot summer it has finally hit its stride and is producing a lot of fruit.

Sun Sugar Tomatoes grow like most other tomatoes.  They need good well drained soil with plenty of  organic matter.  They benefit from an early dose of nitrogen fertilizer and a later dose of fertilizer that is higher in phosphorus (both organic fertilizers of course).  They need consistent water but be careful not to over water or you will get all vine and no fruit.  And make sure they get plenty of sun.  They are a determinant tomato (meaning they grow to a limited size)  but they are still a pretty large plant and will need some support.  A tomato cage works well.   They will continue to add branches through out the summer but the vines seldom get much longer than 3 or 4 feet.  But I have found that they can get a little aggressive by the end of the summer so be sure to give them a little space so they don’t over take your other plants.

Sun Sugar Tomatoes are a hybrid variety so you WILL NOT be able to save seeds from year to year.  But if you are going to grow a cherry tomato, in my opinion this is the one to choose!!  The seeds germinate easily so these are a good choice for growing your own seedlings.  Sun Sugars are still not the most well know tomato so you may have to search a little for them.  But the seeds are easy to find online from several different seed catalogs. And for the past two years we have even been able to find them at our local garden nursery.

    How do I regret not planting this!! I have been buying them at my local markets. They are soooooo good! Definitely a must next year!

    I bet they sure are tasty! I have never grow that variety before. Are they similar to Sungolds? We just love those!

    Have you tried saving the seeds? I know that sometimes they aren’t viable or dont come true to type but I have found that often they do. I haven’t tried Sun gold as I don’t think its available here but I’ve tried quite a few hybrids here.

    They look great. We grew an orange hybrid variety this year. It was our best producer. I don’t think it was Sungold. Maybe we’ll get to try Sungold next year. They sound delicious.

      I checked my records. They are Sungold! How about that? We have really enjoyed them too. To bad I haven’t been paying much attention to their flavor. They’ve been coming in gangbusters. I’ll give them a taste test today!

    Nice article. I planted a Sun Sugar and a Sun Gold this year. Waiting to harvest ! and I’m pretty sure Sun Sugar is an indeterminate variety.

      Becky, I wouldn’t stress too much. Mine are running on about the same schedule. We just started getting the first of ours to ripen this week, you should be fine as long as the plants look healthy they should ripen soon!
