If you’re thinking about growing tomatoes in Maryland, there are a few things you need to know in order to have a successful crop.


What do tomatoes need to grow in Maryland?

When to plant tomatoes in Maryland

Tomatoes need full sun, which means they should get the maximum number of sunlight hours available in a day. They also need well-drained soil that is slightly acidic (6.0- 6.8) and rich in organic matter. Since they thrive best in USDA hardiness zones 5 through 9, tomatoes should do well in most parts of Maryland.

If your soil is heavy or clay-like, you may want to consider amending it before planting your tomatoes. Adding compost or other organic matter will help to improve drainage and increase the number of nutrients available to your plants.

And even in cases where you think that your soil is perfect, it’s still recommended that you perform a soil analysis of the piece of land that you’ll be planting on. This will give you a better idea of what nutrients are lacking and how much needs to be added.

Since tomatoes require enough moisture to grow in the best way possible and produce juicy fruits, you may have to water them quite often. You’ll have to pay close attention to ensure that the soil is evenly moist so that it doesn’t become too dry or soggy.

It’s advisable that you always water them when the soil dries out to a depth of about 1-2 inches. You can also spread a 1-inch deep mulch layer around your plants so that you can lower the probability of encountering weeds while also retaining soil moisture.

The best time to plant tomatoes outside in Maryland is in late April through May. However, if you plant your tomatoes outside in June, you should still have enough time to get a decent harvest. If you’re planting the seeds in readiness for transplanting, you should start doing so in March so that the seedlings can be ready at the earliest possible time in the spring.

Be sure to look out for the indications that it’s time to plant. The first and most important is when nighttime temperatures go over 50 degrees Fahrenheit consistently. Keep in mind that tomato plants will not produce fruit until the temperatures at night reach 55 degrees Fahrenheit.

For this reason, planting when the temperature hits 50 degrees is the best option. This way, the plants will be able to establish themselves and produce fruit as soon as the temperature is high enough.


How long do tomatoes take to grow in Maryland?

The time it takes for tomatoes to mature and be ready for harvesting can vary depending on the type of tomato plant. In most cases, tomato seeds will require an average of 15 days to start germinating.

The seedlings, once established, will then require two to four months before producing fruit. This is, however, dependent on environmental conditions and a farmer’s expertise.

Since tomato plants will be most vulnerable during their first days of life, it’s essential that you give them the best care possible during this time. That way, you will have accelerated their growth rate, so you should be able to enjoy a bountiful harvest in no time.

You can use the following time guidelines to make a rough estimation of the time it will take your plants to grow from seeds to full-fledged plants, as well as when they are most likely to produce fruits.

  • Growing to seedlings from seeds: 5 to 12 days
  • From seedlings to flower-producing plants: 30 to 45 days
  • Developing a bulge from flowers: 9 to 14 days
  • Developing a ripe fruit from a bulge: 20 to 30 days

It’s good to bear in mind that the above timelines are just averages and shouldn’t be taken as gospel. Different tomato plant varieties will have different timelines as well as life stages.

The greatest differences are seen in determinate vs indeterminate tomato varieties. Determinate tomatoes also referred to as bush tomatoes, are varieties that have a pre-determined size. They grow to a certain height, produce flowers and fruits all at once, and then die.

On the other hand, indeterminate tomatoes, also called vining tomatoes or cordon tomatoes continue to grow and produce fruits throughout their lifetime.
