Curly top virus is common in tomatoes, especially in years when there has been a large bloom of mustard weeds. The leaves start to curl up, showing the underside of the leaves, the overall color becomes more yellow, and the veins in the leaf may take on a purple color. There is no cure. The virus is spread by the beet leaf hopper, and when it feeds on the tomato plant it infects the plant. Remove the affected plant to keep from spreading the virus. If still early in the season you can try replanting and still get some tomatoes. While there is no cure you can help prevent infection with weed control. The beet leaf hopper feeds on mustard weed, which was quite prevalent this year. When the weeds die back in late May, the leaf hopper looks for other plants to feed on. Early spring control of weeds will help keep the beet leaf hopper under control.
A tomato hornworm is a destructive larva of the North American hawk moth (Manduca quinquemaculata) that feeds on tomato plants. They feed on the leaves, stems and fruit of all of the night shade family of plants including eggplant. They are difficult to see on the plant. They can be picked off by hand, or sprayed with Bacillus thuringiensis (Bt) which is safe to use on food crops. It will emerge as a moth in June or July, which lays eggs that will hatch in just one week. They overwinter in the soil.
Cover the stem up to the plant’s leaves. You can even cover the first few leaves with soil. Roots will grow along the buried stem to make the plant stronger. Each Bonnie tomato label urges you to plant tomatoes deep, so that a full 2/3 of the plant is underground. That means that if you buy a 10-inch tall plant, all but the top three inches is buried. Why? Because the plant will have a better, stronger root system. Better roots mean better tomatoes.Whether in a pot or in the ground, set each tomato plant so that 2/3 of the plant is buried.We know, we know. This goes against everything you’ve ever heard about “don’t plant too deeply or you’ll kill the plant.” Tomatoes break that rule. They sprout roots along the buried stem. The extra roots strengthen a plant so that it can support more fruit and is better able to survive hot weather. (This applies whether you’re growing in the ground, in a raised bed, or in a container.)In really heavy soil, and that the ground beneath it isn’t hard as a brick. To do this, angle the plant so that the growing tip is above ground. If your soil drains poorly, create a raised bed with potting soil that is piled at least 8 inches above ground level.Once you’ve nearly buried it in soil, only the top few inches of the plant will be exposed. Water well, label the plant (to help you remember which variety you’re growing), and watch your tomato plant grow big and strong. Within a few weeks, your plants with super roots will delight you with a bountiful harvest of lovely fruit. -Info & Photo Courtesy of Bonnie Plants

Determinate vs indeterminate Determinate and indeterminate are terms related to the growth habits of tomatoes. Indeterminates’ are plants that have a vining habit and produce a moderate amount of tomatoes continually throughout the growing season. These are usually referred to as STAKING tomatoes. Determinate plants are more stocky and have one or two full flushes of production, usually resulting in one or two large harvests as opposed to an indeterminates’ smaller but more steady production. Determinates are usually referred to as BUSH tomatoes.
Determinate varieties tend to stay short and relatively bushy. That makes them a good choice for small gardens as well as containers or planters on the back patio or balcony. When using determinates, restart seeds after planting the first set of plants so that when the first set is finished producing tomatoes, plants can be removed and replaced with a new set of plants for another harvest.
At lower elevations you can usually get three rotations in per season.
Example: Start 1st set of seeds in Jan. – plant in March
Start 2nd set of seeds in April – plant in June
Start 3rd set of seeds in June – plant Late July or August
Higher elevations may only get in 2 rotations: start seeds Mid-Feb - plant Mid May
start 2nd set Mid-June - plant August
Indeterminate plants keep growing and need to be staked and tied up to a trellis or other support. You can pinch them back to force more growth below, but it's just as easy to work with them and tie them up. Indeterminates can get very, very big and rambly, so train them to grow vertically to save space.
There is generally no difference in taste or size of the fruit, as this is more dependent on the variety itself than the growing habit. To grow both types of plants, use the determinates in smaller beds due to their stockier growth habit, and indeterminates in back where they can be trellised
Heirloom - A old variety which has been maintained either because it has appealing attributes like extra large size, unusual coloring, special connoisseur qualities, or because of family sentimental reasons. Because heirloom tomatoes haven't been 'worked on' by plant breeders, they don't usually have much disease resistance. Many diseases can be essentially prevented or delayed by mulching the soil surface to prevent disease spores in the soil splashing up and infecting the young plants. Mulching plus fungicidal sprays (if you can be bothered) mean that heirlooms can usually be grown successfully in all but the very hot humid areas notorious for tomato disease
Hybrid - this is a variety created by deliberately and painstakingly taking pollen from an existing open pollinated tomato and putting it onto a different open pollinated tomato. The seed gives a first generation (F1) that are extremely uniform. But keeping seed and resowing it gives a highly varied and non-uniform lot of plants and fruit. The original cross to create the F1 seed has to be done every year. The advantage of hybrids is vigor, and the ability to use a parent known to be disease resistant.
Native Seeds- can also be used to grow vegetables, flowers, trees or shrubs. Besides the expected drought tolerance of desert plants, many of these crops are resistant to rusts, insects, chemicals, and other stresses. They provide an irreplaceable "genetic library" to draw upon to ensure sustainable, environmentally safe agriculture in the future. "’Ancient seeds for modern needs’, is the motto of Native Seeds/SEARCH, a non-profit organization based in Tucson, Arizona. Since 1983 the group has been collecting seeds of food plants used by the native cultures in the arid region of the southwestern US and northwestern Mexico, sometimes referred to as the Chile Pepper Nation. Their mission has led them not only to conserve the rare crops adapted to arid lands, but also to preserve cultural traditions by distributing crops back to Native American communities.”
For more information visit: http://www.nativeseeds.org
Organic Seeds- are also available to the home gardener. Many of the seeds you purchase today may have been genetically modified for disease and pest resistance, increased nutritional content , higher yield. But unlike the traditional hybridizing of plants mentioned above, this modification is done at a genetic level, often splicing genes from unrelated species to gain the desired trait. The mechanical transfer of genetic material outside of natural reproductive methods and between genera, families or kingdoms, may pose biological risks. For example, it’s uncertain what unintended effects transgenes designed to resist pests might have on beneficial insects or how they could upset various balances in nature. The debate is still raging. Genetically modified plants are sometimes described as bioengineered or transgenic. Organic seeds are not genetically engineered, nor are they ever treated with fungicides or pesticides. There are many commercial sources available. (ie: www.seedsofchange.com )
Tomatoes come in a varity of sizes shapes colors and flavors. Some ar better suited for eating fresh while other do better in cooked dishes or being canned or frozen.
Listed below is information on many different varities and their best uses. - Information Courtesy of: http://www.naturalhub.com/grow_vegetable_cultivars_tomato.htm

-cooking or fresh eating
Plum tomatoes often have fine thick flesh and reduced amounts of pulp. This makes them good for holding shape when canned, and it means they also slice quite well. Because they have less pulp they cook down for sauces faster than some. A good tasting cultivar may be the only tomato you need. It has to be said tho', buying canned plum tomatoes from the supermarket is often cheaper and definitely easier than growing and canning your own.
Amish Paste Staking variety. 'plum' type multi purpose tomato. Because it has few seeds and thick fruit walls it is particularly useful for making sauces or any dish where canned tomatoes are called for. It produces well. A variety maintained for many years solely by the Amish religious sect of USA. Main season.
Costoluto Genovese Staking variety. Rigged, fluted, and lobed, these uneven medium sized tomatoes are vigorous, bear well, but because of their shape are difficult to can/preserve. Like most plum tomatoes, they are otherwise suitable for sauce or fresh eating, altho' they are too small and uneven to be properly considered a slicer.
-the primo slicer for sandwiches or cooking
Beefsteaks are the very biggest tomatoes. Their pulp cavity is generally relatively small, and always compressed and distorted by the extensive placenta wall, giving the 'marbled' appearance of a steak. Because of the compressed pulp cavity and networking of the fruit wall as placenta, beefsteaks hold together well when sliced, and together with their large size, make them the ideal 'slicer' for sandwiches. Because of their high fruit wall to pulp ratio, they also cook down well for sauces. There is a lot of variation between varieties in the density of the flesh, it's juiciness (i.e. firm or very soft when ripe), and in the size and softness of the central 'core'. Flavor, as always, can vary, according to the ratio of sugars to acids, and according to the relative amount of sugar or acid present.
Big Beef F1 Staking variety. Outstandingly productive, easily out producing most other large, (about 100mm/4 inches in diameter/ 280 gms ) very regular fruit shape, with no cracking, produce large tomatoes even toward the end of the season, very good flavor. One of the very best of the large main season varieties.
Big Rainbow Staking variety. A spectacular looking tomato grown from at least the 1900's in the USA. Basically a large to very large yellow beefsteak, as the fruits ripen, go through a phase where they resemble a rainbow - 'greenback' on the shoulders, yellow in the middle, and with red blushed pink on the blossom end. The early set fruit can be very large at 900grams/2 lbs or more. The flesh is marbled red and orange. It is relatively free of fruit defects, and bears well. Highly rated in taste tests. Main season.
Brandywine Staking variety. A large beefsteak. Not as tall a some staking plants, this old cultivar (pre 1885, from the Amish community in USA) is renowned for its flavor. The fruit are large, between 400 and 700 grams. They are subject to minor cracking on the top, and are a rather soft fruit, but the flavor is outstanding, with both high sweetness and acidity, making for full flavor. The flavor can be poor in unfavorable seasons. Moderately productive. Main season. It has no disease resistance, and is unsuited to very humid hot areas where disease is a problem.
Evergreen Staking variety. Ripens green turning yellow. Medium sized fruit. The solid dense fruits are well suited to salsas, as well as slicing for frying or sandwiches. Main season.

Yellow Brandywine- a deep yellow, near orange color 'sport' of 'Brandywine'
-for summer salads, Fresh eating
Seed locule (pulp) tends to fall out if they are sliced. Abundant seed pulp makes them a slow reducer if they are being used for sauces. But their smaller size makes them ideal for cutting in half or in quarters to have with a salad.
