Thinking about what tomato seeds to order this year? For starters, you should read the plant growth and fruit production results of our Briggs Ave Community Garden tomato trial. Probably just as important for your seed purchase decisions is how did those tomatoes taste? The tomatoes included in the trials were:

  • Lemon Boy Plus
  • Mountain Defender
  • Better Boy Plus
  • Mountain Flush
  • Celebrity Plus
  • Mountain Regina
  • Carbon

The “Mountain” tomato varieties were donated by Dr. Dilip Panthee, head of NC State’s Fresh Market Breeding program and shared similar disease resistance characteristics to the “Plus” tomatoes. Carbon, consistently rated one of the best-tasting heirloom tomatoes, had none of these resistance characteristics, and was our “control” for taste.

While all of the varieties can be considered “slicers,” there were clear differences in overall size. Lemon Boy Plus, with an average fruit size of 3.9 oz compared to 8.6 oz for Carbon and 7.8 oz for Mountain Defender, were half the size of many of the red slicers. True to its name, Lemon Boy Plus was a distinct yellow while the remaining tomatoes ranged from bright red (Mountain Flush) to almost dusky red-purple (Carbon).

Our taste tests indicated that most of the varieties attempted to provide the best of both worlds, balancing both sweet and acid notes. Interestingly, people didn’t always agree on the finer points of their flavor with regard to what was sweet or acidic. One thing that everyone seemed to want was deep, often earthy flavor. They also preferred a meaty to a thin or mealy texture.

Unfortunately, Celebrity Plus was a taste-test no-show. Mid-summer production slowed to the point where we did not have enough tomatoes to taste. But production did pick up, and in the end, Celebrity Plus was one of the last plants standing.

Mountain Defender: Balanced

Mountain Defender did not have many supporters, only getting two first place votes. Many tasters didn’t find it any better than a supermarket tomato–bland and not very interesting. While the flavor was balanced, it had neither sweet nor acid notes that interested tasters. While the appearance was a nice pink-to light red, it was not particularly distinctive. Tasters also didn’t have many good things to say about texture. Overall it was found to be serviceable but not particularly interesting.

Mountain Flush: Juicy Tending Toward Sweet

Mountain Flush didn’t fare much better than Mountain Defender in the ratings. With only three first place votes, it finished with Mountain Defender at the bottom of the rankings. While a number of raters noted its looks, the texture and flavor didn’t match up. A few liked its juicy qualities, but most found it too watery. Similarly, the flavor was too mild for most, tending towards sweet.

Better Boy Plus: A Hint of Classic Taste

Better Boy Plus was a tomato that didn’t quite live up to its looks. Often described by raters as a ‘beautiful’ or ‘perfect’ tomato, with a strong red color with a few orange spots. However, while many raters tasted a hint of classic tomato flavor, it was too weak. As with many of the tomatoes, raters were mixed as to how good the sweet/acid balance was, with raters falling all along the scale. Similarly, the texture responses ranged from meaty to mushy. Many noted it had the perfect characteristics for a sandwich slicer. It ended up scoring in the middle of the pack with nine first place votes, and the same number of second place votes.

Lemon Boy Plus: Strong Third Place

Tasters found Lemon Boy Plus to be firm but at times tough-skinned. There were mixed results with regards to flavor. While some found it bright, others found it boring. Similarly, while some liked its acid bite, others found it too sweet. Nonetheless, Lemon Boy Plus had supporters in the final rankings, getting nine first place votes and 20 second place votes–more second place votes than any other tomato. While a number of tasters commented on the distinct yellow color, it’s hard to know how much this influenced final rankings.

Carbon: Vaunted Heirloom Comes in Second

Our heirloom control, Carbon, ended up second in the rankings. It received 10 first and 14 second-place votes. For many, it was good but not the best. Its looks had a lot going for it, with raters loving the deep red, purple, and green variegation. The acid/sweet balance was good, described by many as slightly acidic. However, on flavor it fell short for a number of people. A number of raters found it too mild, specifically noting that it was not as rich as Mountain Regina. While it had some nice earthy notes, they were not strong enough.

Mountain Regina: “The Perfect Summer Tomato”

Mountain Regina ended up at the top of our rankings, scoring an average of 4.07 on a scale of 1 to 5, the highest average score of the taste test. In addition, 29 of the 61 tasters ranked Mountain Regina as their favorite tomato in the trial. Twenty-one other tasters ranked it as either their second or third favorite. Raters described it as an heirloom tomato in appearance–a beautiful deep red with almost a hint of purple; smooth and meaty flesh and not too many seeds. The “classic, old-fashioned” flavor won many raters over with its deep, rich umami-like notes. Many considered it having a perfect acid/sweet balance with just the right hint of sweetness and not too much acidity. A number of raters said it was the perfect summer tomato–a 10 out of 10. These comments on flavor and appearance for Mountain Regina mirrored Carbon, our one heirloom variety.

The results of this year’s tasting trials had only one definitive outcome: people don’t always agree on what they like in a tomato. Even the lowest ranked tomatoes received some first place votes. Raters also didn’t necessarily agree on texture or degree of sweetness or acidity in varieties. While some of these differences may have been from variations between samples, it also is a reminder that people’s taste buds respond differently, and people want different flavors out of a tomato. Hopefully, the results of this taste test will help you find a tomato variety (or two) for your summer planting that matches your preferences.

Stay tuned for the 2026 tomato trial where we will test different root treatments to see if they make a difference in production.

To Do in the Garden: February 2026

By Gary Crispell, NC State Extension Master GardenerSM volunteer of Durham County

In central North Carolina, frigid temperatures and snow are ushering in February 2026. (Image credits: Sabrina can den Heuvel/Pixabay; Melinda Heigel)

Well, friends, wasn’t January fun?  I haven’t worn so many clothes simultaneously for so long since the BIG SNOW of 2000 (or maybe since I was a kid in upstate New York).  It has been (expletive deleted) COLD!! 

The Accidental Cottage Garden (ACG) has gone into deep hibernation.  I have managed to get a solid covering of wood chips on some of it.  (Good thing I kept the tractor when I dissolved the landscape company.)  My barely functioning left knee prevented any detail work in the ACG.  (By the time you read this that problem will have been taken care of.)

February is the official start of gardening season (if there isn’t any white stuff covering the beds).  I know that is a fact.  I saw it on the internet.  There are many more things to do this month than in January, so lets put on all of our clothing and get started.

Lawn Care

Cool season grasses (i.e. fescue and bluegrass) should be fertilized with a slow-release fertilizer following the recommendation of your SOIL TEST.

Late February/early March is the best time to apply a preemergent crabgrass preventer.  There are several easy to use granular products on the market.  Be sure to read and follow the directions on the label for safe and proper handling and application.  Calibrate your spreader to ensure accurate application amounts.  Too little will not give you effective control and too much may damage the turf.

Fertilizing

See Lawn Care above and Planting below.

Planting

And so, it begins.  The vegetable garden.  The reason for existence, for frozen fingers in February, summer sunburn and the endless supply of liniment in the medicine cabinet.

According to NC State experts, “Some cool season crops like Brussels sprouts, beets, collards, kale, parsley, and spinach will survive even if the temperature drops below 26 ºF for an extended period of time.” (Image credit: NC State Extension)

It is time for root vegetables and salad (and beef Bourguignon—which you can’t grow in the garden).  Early “plantables” include cabbage, carrots, leaf lettuce, onions, potatoes, radishes, rutabagas, spinach and turnips.  Work a little fertilizer into the soil that was tested in October (while it was still free to do so) following the recommendations of said SOIL TEST. More winter weather ahead into spring? Learn how to protect your crops.

Be cognizant of soil moisture levels.  Mother Nature has not done much in that department since October of 2025, but she can be really fickle.  We’ll probably have monsoons in April.

Pruning

If you have been ignoring previous posts, now it would be a good time to prune bunch grapes and fruit trees.

Also due for judicious trimming are summer flowering shrubs and small trees.  That list includes rose of Sharon (Hibiscus seriatcus) crape myrtle (Lagerstroemia spp.), butterfly bush (Buddleia davidii), and hydrangeas that bloom on new wood (Hydrangea arborescens & H. paniculata). Note: now is not the time to prune spring-flowering shrubs. You should prune these shrubs AFTER they have flowered in spring, but before the next year’s flower buds are set. If you prune these shrubs in winter or early spring, you will remove many of the flower buds and have fewer if any spring blooms. Spring-flowering shrubs that sucker readily from the base can benefit from some thinning (more here). Examples of spring-flowering shrubs are lilacs, forsythia, viburnums, honeysuckle, chokeberry, mock orange, and weigela.

While you’re out there, late winter to early spring is the time to whack back the ornamental grasses, also. 

Got some overgrown shrubs that you’ve been meaning to (or are reluctant to) prune heavily?  Go for it now.  I understand that if you’ve never done it before it can be a bit intimidating, trust me.  The plant will almost always not only survive but also thrive.  I am aware of the never-more-than-a-third rule, but sometimes that is not enough.  This is known as renewal or rejuvenation pruning and can benefit overgrown and mature specimens. So if it needs to go back to 12”-18” …. go for it.  Chances are you and the plant will be glad you did.

Spraying

The orchard needs attention.  Peaches and nectarines should be sprayed with a fungicide to prevent leaf curl. Spraying a dormant oil on the fruit trees will help control several insects later in the year.

Other Fun Stuff to do Outside in February

It’s the perfect time to propagate trees and shrubs through hardwood cuttings and tidy up unoccupied bluebird houses. (Image credit: University of New Hampshire Extension; NC Cooperative Extension)

Perennials can be divided as we head into spring.  Do it before the above-mentioned monsoons. Read up on it now and be ready.

Many landscape plants can be propagated via hardwood cuttings this time of the year.  Some of the plants in the category are crape myrtle (Lagerstroemia spp.), flowering quince (Chaenomoles spp.), junipers (Juniperus spp.), spiraea (Spiraea spp.) and weigelia (Weigelia spp).

Bluebirds will be most appreciative of a thorough house cleaning before the spring nesting season.  Remove all the old nesting materials and let them start afresh.  It’s like clean linens for them.

Oh, yeah.  Lest we forget…order flowers or other living things from the plant kingdom for your significant other.  Just for the record, guys like flowers and plants, too.  Happy Valentine’s Day, Y’all. Think positive thoughts about an early spring sans late freezes.
