When Can Tomato Plants Go Outdoors in Massachusetts 2019

Tomatoes are a staple of many home gardens, and it is important to know when it is safe to plant them in your area. In Massachusetts, the weather can be unpredictable, and the last thing you want is to have your tomato plants damaged by a late frost or cold snap.

What is the Average Last Frost Date?

The average last frost date in Massachusetts varies depending on the location. Coastal areas tend to have later frost dates than inland areas. The average last frost date for Boston is around May 10th. For western Massachusetts, it is around May 15th. It is important to keep in mind that these are just averages, and frost can occur outside of these dates.

When Can You Plant Tomato Seedlings Outdoors?

Tomato seedlings should not be planted outdoors until after the average last frost date for your area. This is because tomato plants are sensitive to cold temperatures and frost. If you plant them too early, they may be damaged or even killed by a late frost.

Once the last frost has passed, you can begin to harden off your tomato seedlings. This means gradually introducing them to outdoor temperatures and sunlight. Start by placing them outside for a few hours each day and gradually increase the time until they are spending the entire day outside.

When Can You Plant Tomato Seeds Directly in the Ground?

If you prefer to start your tomatoes from seed, you can plant them directly in the ground after the last frost date has passed. However, keep in mind that it may take longer for your plants to mature than if you had started with seedlings. You will also need to make sure the soil temperature is warm enough for germination.

Before planting your tomato seeds, prepare the soil by loosening it and adding compost or fertilizer. Plant the seeds about ? inch deep and cover with soil. Water the soil regularly and keep it moist until the seeds germinate.

How to Protect Your Tomato Plants from Cold Weather

While you may do your best to plant your tomatoes after the last frost date, there is always a chance of cold weather or frost. To protect your plants, you can cover them with a frost blanket or fabric. This will help to trap heat and protect the plants from frost damage.

You can also use water to protect your plants from the cold. Water has a high heat capacity and can help to regulate the temperature of the soil. Before a cold snap, water your plants thoroughly. Cover the soil and plants with a layer of mulch to help retain moisture.

In Conclusion

Knowing when to plant your tomatoes in Massachusetts is important to ensure a successful crop. Wait until after the average last frost date for your area before planting seedlings or seeds directly in the ground. Protect your plants from cold weather by covering them with a frost blanket or fabric, and use water to help regulate the temperature of the soil. With proper care, you can enjoy a bountiful harvest of delicious tomatoes.
