It usually takes from 55 days to 105 days for a tomato to reach maturity with many maturing at 70 days or later. Varieties that grow from plant to mature fruit within 50 to 69 days are often considered early ripening tomato varieties. Among these types are hybrid and heirloom varieties.
Early to Ripen, Early to Wane
Many determinate or compact tomatoes are early ripening varieties. These plants characteristically grow to reach a certain size, set their fruit and then begin to decline. They typically bear fruit in fewer than 70 days. The disadvantage is that many stop producing fruit early in the summer season. Many home gardeners plant large fruiting tomatoes, such as Beefsteak, as well as early varieties. The Beefsteak varieties commonly ripen late. By planting both late and early tomatoes, the gardener can enjoy a variety of tomatoes throughout the season.

Unlike supermarket-sold hybrid tomatoes that withstand being harvested green, being shipped over long distances and being handled extensively, heirloom tomatoes tend to be less uniform in appearance, somewhat fragile and very flavourful. Many heirloom tomatoes are also early ripening varieties.
