Last year, inspired by some amazing organic gardens we visited, we experimented with new ways to grow tomatoes.
Our tomato plants were more vigorous and healthier than they have ever been!
In a 20 square foot area, we harvested over 100 lbs of delicious tomatoes from just six “Early Girl” tomato plants , a popular variety that can be easily found in most nurseries.
Today I am excited to share with you the tips and tricks we learned on how to grow tomatoes like an expert and get a huge harvest!
Tips number 1, 3 and 4 are something new we tried that made all the difference!
Before we go into details of the tomato growing techniques, these are a few basics that apply to all vegetable gardening: plenty of sun, good soil, and productive varieties that are suited for your climate.
The easiest way to build great soil on any site is to create a simple raised bed. Here are lots of tips and tutorials on DIY raised bed gardening-
Tomatoes come in determinate and indeterminate varieties, which is written on the plant label.
Determinate varieties are small compact growers with a short harvest season, so our tips 3 and 4 will not apply to these.
Most of the great tasting and heirloom tomatoes (for example- “Early Girl”, “Cherokee Purple”, “Sweet 100“, “Brandywine”) are indeterminate, which means they continue to grow and produce tomatoes all along the stems throughout the growing season. These are the tomatoes we prefer to grow.
Secret 1 : Tomatoes hate cold feet.
“The earlier we plant, the sooner we get our first tomato, right? ” Actually, no.
Tomatoes hate cool soil temperatures. The ideal soil temperatures to grow tomatoes are between 70 – 90 degrees Fahrenheit. (Note: if you garden where spring is already this hot, then skip this step!)
Temperatures dipping below 55 degrees Fahrenheit stops plant growth. The less active the growth cycle, the more likely the plants will have insect and disease problems.
In most places, the night time temperatures can be quite cold in March, April, or even May.
To solve this problem, we used the plastic mulch method which we learned from amazing gardeners who grow tomatoes successfully even in challenging climates. ( Some of the helpful resources are affiliate links. Full disclosure here. )
Open up a few black plastic trash bags, lay them on top of the soil, secure along the edges with wood planks or rocks. Cut 3″ to 4″ diameter holes for the plants. We planted our tomatoes on a 30″x30″ grid.
The plastic was able to raise the soil temperature by 10 – 20 degrees Fahrenheit during the day, and hold the heat better at night, which was perfect for most spring days and nights when temperatures are between 45 – 65 degrees.
As the weather gets warmer by summer, the plants will have enough leaves to shade the plastic and prevent it from getting too hot.
We could tell how happy the plants were. In a couple of weeks, the seedlings were growing rapidly and looking super healthy!
Secret 2 : Plant tomatoes deep.
Prune off the bottom leaves and plant about 2/3 of the plant underground.
Tomato plants have this amazing ability to grow roots along the buried stems, which will make the plants stronger.
Because tomato stems grow roots easily, we can propagate new ( and free!) plants in just a week from stem cuttings of a big plant! Tutorial here-
Secret 3 : Prune fearlessly.
Have you grown a huge tomato plant, only to get a ton of leaves and very few fruits? Then it just wilts and dies?
The best solution is to prune tomato plants regularly.
Pruned plants allow more sun light to come through and more air flow. The leaves dry faster after a rain, so they are less susceptible to the diseases such as blights.
The orange arrow indicates the main stem, and the blue arrows indicate the side shoots / suckers which can grow into a stem. The goal is to leave only 1 or 2 stems growing ( some say up to 4 stems ), and prune off all the suckers.
It is very easy to miss one until it has grown too big. So do this at least twice a week, and be ruthless!
See how thick and healthy this main stem is? Instead of growing 50 to 100 stems, the plant is able to concentrate it energy on the main stem and keep producing fruits. ( This method is suited to indeterminate tomatoes which we talked about at the beginning.) Continue To Next Page…
