This fungus is usually found in that are moist and not usually found in arid dry areas.Appears first as irregular small brown dead spots on the older lower leaves. As the early blight spot grows to half an inch it displays in a pattern like a “bulls-eye”. The leaf may then turn yellow. If the tomato plant is affected by blight as the fruit begins, then the older fruit will show sunken dark leathery spots.

Late Blight: Is a fungus that affects tomato plants when there is an extended period of damp weather and cool nights that come with warm muggy days.
The fungus can be identified as black greasy areas on the tomato leaves.
The under side of the tomato leaf will show a fine gray mold. This generally happens in wet spells.
Hot dry weather will prevent or stop this late blight fungus.

Cherry Tomatoes

Cherry tomatoes are considered to be the smallest tomato of all the varieties. Their size typically ranges from a small marble to the size of a golfball.

Family Heirlooms: These are tomato seeds that have been handed down for many generations through a family.
Created Heirlooms: These created heirlooms refer to two crossed varieties that have been bred multiple times to stabilize desired characteristics and eliminate undesirable characteristics.
Mystery Heirlooms: These are heirloom varieties which happen to be a new product of natural cross-pollination of various other heirloom varieties.

*Note: All heirloom tomato varieties are open-pollinated. However, not all open-pollinated varieties are heirloom varieties.

Hybrid tomatoes:

Hybrid tomato plant varieties are intentionally bred as a cross in between 2 uniquely different varieties, quite often to cultivate specialized characteristics.

F1 hybrid: the very first tomato generation seeds which come from plants that have 2 specific parents
F2 hybrid: these are tomato seeds which come from crossing 2 unique F1 hybrid parents
