You’ve had a great season tending to your tomato plants! But with the summer winding down and chilly days coming soon, you may be wondering what to do with your tomato plants now.
Get a head start on spring by preserving the seeds from your tomatoes.
Tomato seeds might be available at the store year-round, but saving your own is satisfying and easy. Luckily, September is the perfect time to begin planning for next year!
How do I pick which seeds to preserve?
The general rule of thumb is to only take ‘open-pollenated’ seeds or heirlooms. Hybrid plants often produce sterile seeds. Or, they do not produce seed with the same desirable traits of the parent plant.
Harvest seeds from tomatoes that are healthy and embody the characteristics you’re interested in preserving. For example, you could pick seeds from the juiciest tomatoes, or the ones with the most interesting colors. It’s your choice, but make sure you pick from healthy plants. Unhealthy plants could carry illnesses.
Method 1: Air-dry
This method is pretty simple. Open the tomato and remove the seeds, squeeze them onto a paper towel, wait for the seeds to air dry and then store them in a jar, an envelope or even the same napkin. This method is quick and straightforward.
Method 2: Ferment
It’s not absolutely necessary to ferment your tomato seeds, but fermenting makes it easier to completely separate seeds from the gel that surrounds them. Fermenting also eliminates the bad seeds and reduces the possibility of seed-borne disease for next season.
1. Wash the tomatoes. Slice each in half across the middle (not the end with the stem). Squeeze the seeds and juice into a (labeled) glass or plastic container.
2. Set containers aside when half-full. Place containers in an area that is out of direct sunlight and out of the way, so the fruit flies and odor will not bother you.
3. Let the seeds sit for three to five days or until the surface of the container shows a whitish mold. This is a good thing! The seeds should be floating at this point. In warmer climates, you may need to add some water to keep the seeds afloat.
4. Gently scrape the mold off with a spoon. Do not remove the seeds.
5. Fill container with water and then stir it. The seeds you want will sink to the bottom.
6. Pour off the excess to remove floating seeds and pulp.
7. Repeat the process until the good seeds, at the bottom, are cleaned.
8. Pour the good seeds into a strainer, then rinse and drain them.
An airtight container works best for storage. When packaged correctly, tomato seeds remain usable for up to six years!
You can place the seeds in the refrigerator or freezer, but the seeds will last even when stored at room temperature. When you’re ready to use the seeds, if they’ve been chilling in a refrigerator or freezer, let them adjust to room temperature first to prevent excess condensation from creating any damage.

It’s the moment you’ve been waiting for – tomatoes are ready to harvest! You can almost taste the delicious flavors of that first bite.
Whether you’re cooking, canning, freezing or simply eating your tomatoes raw, you’ll want to pick them at the perfect moment. These harvesting tips will ensure your organic tomatoes are ripe when picked.
Timing is Everything
One of the first steps to a successful harvest is keeping a close eye on your tomatoes to determine the best time to pick. Tomatoes are typically ready to harvest 60-85 days after planting seedlings outdoors. However, timing can change depending on your climate and the variety of tomatoes you’re growing.
If you’re planting determinate tomatoes, be ready for a large harvest all at once. These varieties typically set and ripen their fruit within about two weeks.
Indeterminate tomatoes can ripen all summer long, so keep an eye on these varieties throughout the season to ensure peak harvesting times.
Color is Key
When the tomato has even color throughout, it is typically ready to be harvested. Tomatoes often ripen from the bottom up, so check the bottom of the tomato first for mature growth color. Once the entire tomato has reached this color, it is ready to be harvested.
Tomatoes need heat to harvest, and not necessarily light. They continue to ripen on overcast or cloudy days, as long as the temperature is warm. Tomatoes can even continue to ripen off the vine. If you live in an area with an especially hot climate, it’s better to pick the tomato from the vine before it reaches its mature color. Tomatoes will continue to ripen and change color as long as they are stored in warm temperatures.
Trust Your Instincts
When it comes to harvesting tomatoes, trust your intuition. Ripe tomatoes should feel firm, but not hard. Overripe tomatoes will be soft and can be composted. Ripe tomatoes should feel full and heavy. Under ripe tomatoes are often lightweight and need more time on the vine before harvesting.
Keep a close eye on your tomato plants as harvest times come near. Overripe tomatoes typically become too heavy and fall from the vine. This can lead to disease and rot, causing you to lose a large portion of your harvest.
When tomatoes are ready to harvest, simply twist off the vine by hand or use clippers for larger tomatoes. Cut the stem close to the fruit and enjoy!

When it comes to insects in your garden, don’t be quick to kill. Not all insects are enemies. In fact, most insects are essential players in your organic garden’s success. Others are neutral and don’t cause any harm. Yet some will ruin your harvest.
Spotting the difference between the good and the bad can be tricky, so keep your eyes peeled.
Four Common Tomato Plant Pests:
Hornworms – These destructive caterpillars can grow to about 3-3½” at full size, but their green color makes them difficult to spot. If you spot hornworms, spray with water or remove by hand. However, where there is one, there are usually more. If there is a large infestation, consider spraying tomato plants with an organic approved pest control.
Fruitworm – Adult tomato fruitworms are moths, typically yellow or olive in color. They often lay eggs near the leaves of the plant. If you see fruitworms, check leaves for eggs. Larvae feed on leaves and foliage before moving to the tomato, giving you more time to stop potential damage.
Potato Aphids – These tiny insects are usually found in dense clusters. Potato aphids are typically not serious enough to kill plants, but a large enough infestation can stunt growth and lead to mold and disease. If you spot an infestation, remove it and be sure to throw in the garbage. If thrown on the ground, aphids will re-infest the plant. To control, apply insect soap.
Beet Armyworm – Similar to the fruitworm, beet armyworm adults are moths with gray and brown upper wings and white or pale gray lower wings. They typically lay eggs on the underside of leaves. When larvae hatch, they feed on foliage before attacking the tomato itself. Remove beet armyworm caterpillars by hand before they become moths.
When it comes to tomato pests, the best way to stop damage is to spot pests early. Keep a close eye on your tomato plants, especially in the early stages. Introduce beneficial insects such as lacewings or ladybugs into your garden to naturally control common pests.

No other flavor in the garden can compete with sun-ripened tomatoes! Just seeing their bright, shiny color emerge gets us giddy!
We want to make sure you get to experience the joy of your homegrown, golden delights this year.
So, if you spot a worrisome sign on your tomatoes, here’s how to identify and fix it – the organic, natural way!
Dr. Tom A. To: How to Identify and Fix Common Tomato Diseases and Problems
The Mark of Dark Spots. First, you’ll see tiny spots on tomatoes’ lower leaves, usually after the first fruit has set. From there, the spots grow larger and begin to look like a target. That’s early blight.
To fix, remove infected leaves as well as lower leaves. Water in the morning to prevent further spread of this fungus. Low nitrogen levels often cause early blight, so feed with Tomato-tone monthly.

The Bruise Blues. If small, sunken spots or what looks like bruises appear on your ripe tomatoes, that’s anthracnose. This fungus emerges as the weather gets hot and humid – usually 80° or warmer.
So, harvest ripe tomatoes as soon as possible. These are safe to eat if you cut off the bruises. Then water tomatoes in the morning.
So Many Spots. If tiny, greyish-brown dots cover your tomato leaves, Septoria leaf spot is to blame. Soon, leaves will fall off. Though, a harvest will usually still happen.
To remedy, remove all infected leaves. Then apply a copper fungicide – if you’re organic gardening.
Brown Bottom. See circular brown spots on the bottom of your half-grown tomatoes? That’s blossom-end rot, which is usually caused by a lack of calcium in the soil. Blossom end rot should only happen to a few tomatoes early in the season, not the whole bunch.
To fix, use an organic tomato fertilizer with calcium.
Built to Wilt. Wilting, curling leaves could be bad news for your tomatoes. If paired with stunted grown or browning veins or blotches, your tomatoes have Fusarium or Verticillium wilts. These diseases are caused by a super vicious fungus in the soil.
And, there’s no cure for it. Remove and rid your garden of these tomatoes. Do not compost. Then, solarize the soil to kill the fungus. Otherwise, when you plant veggies in the same area, they, too, will get this disease for the next 4-6 years.
Next time, when you’re growing tomatoes, select disease-resistant varieties to avoid some of these common problems.
Imagine having a successful, bountiful tomato harvest every season — juicy, red tomatoes ready for the kitchen.
The good news? You can! Tomato care isn’t hard.
When it comes to growing tomatoes in your organic vegetable garden, the secret is in the soil. Maintaining consistent soil moisture is crucial for a successful harvest.
When, and how frequently, you should water your tomato plants depends on the variety, size and location.
Start Your Seedlings
When starting tomatoes from seed, the soil can dry out quickly since seedlings are typically in small containers or trays. Check soil daily to ensure it has not dried out.
However, seedlings require very little water. Use a spray bottle to mist seedlings and keep just the top of the soil moist.
If the soil becomes too wet, move the seedlings to an area with increased air flow and hold off on watering again until needed. Never let seedlings sit in a puddle of water.
As seedlings begin to sprout and grow, they will need more water. If the soil in the tray dries in less than 24 hours, it might be time to move your seedlings to the garden or a larger container.
Growing in the Garden
When you plant tomatoes right in the ground, the roots can extend deep into the soil as they seek out water. Water newly planted tomatoes well to make sure soil is moist and ideal for growing.
Early in the growing season, watering plants daily in the morning. As temperatures increase, you might need to water tomato plants twice a day. Garden tomatoes typically require 1-2 inches of water a week.
Container Tomato Plants
Tomato plants grown in containers need more water than garden tomatoes. Soil in containers heats up faster which leads to more water evaporation.
A good rule of thumb for containers is to water until water runs freely from the bottom. Water in the morning and check the soil moisture levels again in the afternoon. If soil feels dry about 1 inch below the surface, it’s time to water again.
Keep Tomatoes Well Fed
Adding organic mulch to tomato plants reduces evaporation in the soil. That means less watering, so you can save time and resources.
Add Espoma’s organic Tomato-tone, a slow release premium plant food, for bigger, healthier roots that can withstand a little drought and excess heat.
There are many factors that affect how much water tomato plants need, such as weather conditions and the size and growth rate of the plant. Every plant is different! The best way to give your tomatoes the care they need is to closely monitor the plants and the soil moisture weather.

Add mulch, a natural covering on top of soil, to keep moisture in, block weeds and provide added nutrients. But did you also know that mulch is particularly important for tomato plants?
If you grow tomato plants, then you have to understand the importance of mulch.
Why is Mulch So Important for Tomatoes?
1. Mulch Protects
Many tomato plants grow large, heavy fruit. Mulch protects the lowest-growing fruit from resting on the ground and developing rot.
2. Mulch Blocks Weeds
Weeds are usually no problem for tomatoes since the large plants, with their dense foliage, shade out and smother any weeds. However, mulch around staked or trellised plants will keep down those baby weeds, so they won’t rob the plants of water and nutrients.
3. Mulch Saves Water
Staked and trellised plants usually benefit from mulch to save moisture. More exposed to sun and wind than unstaked plants, they lose more water through their leaves. It takes extra effort to provide them with an ample and even supply of moisture, but in dry climates, it’s worth it.
4. Mulch Keeps Plants Clean
A mulch blanket under your plants keeps soil from splashing onto the leaves, which helps prevent disease, something tomatoes are especially prone to.
How to Mulch Tomatoes
Many make the mistake of laying mulch around tomatoes too early. You should wait until late spring or until the ground has really warmed up. Adding mulch will inhibit soil from warming and delay the harvest a few weeks.
Once the soil has warmed, feed your tomatoes again with Tomato-tone. Then spread a 2-3” layer of organic mulch. Be sure to leave 2” of room around the stem so water can reach the roots. Water well.
The Best Organic Mulches for Tomatoes
Shredded Leaves: Composted leaves are great for vegetable gardens because they provide natural weed protection and increase moisture retention.
Grass Clippings: If you apply organic lawn fertilizer, dry grass clippings are a great option. They mat together to protect plants and retain heat.
Straw: Straw makes great mulch for tomatoes. But stay away from hay, as it’s full of seeds. Spread a 3-6” layer around tomatoes.
Newspaper or Cardboard: Newspaper is best for blocking weeds. Cut or tear into strips that fit easily around plants.
Peat Moss: Peat moss slowly decomposes over the growing season, adding nutrients to the soil. Water plants thoroughly before spreading peat moss, however, because it sucks a lot of moisture from the soil.

You’re on your way to growing the perfect tomatoes. Once you’ve selected your favorite varieties, planted and cared for the seedlings, all that’s left is to take a bite into your first harvest.
But wait. That tomato doesn’t look so appetizing.
If a dark, water soaked spot has formed on your tomato you may have blossom-end rot. This problem is likely caused by an imbalance of calcium in the plant. You may also see this on peppers, squash, cucumbers and melons. The spot enlarges and darkens rapidly as fruits develop. Large spots will dry out and appear to be leathery.
Tips to Keep Blossom End Rot Away
The reasons are many as to why the plant may not be able to take up enough calcium to support the fruit, but most lie in the soil. The best way to prevent blossom end rot is to have a soil test done before planting to determine if the soil has adequate calcium.
Other reasons include:
1. Fluctuations in soil moisture
2. Excess of nitrogen in the soil
3. Root damage
4. Soil pH that’s either too high or too low
5. Soil that’s too cold
6. Soil that’s high in salts
Unfortunately there’s no use saving these tomatoes. Pick off damaged fruit as soon as you notice the rot and compost them.
