1.  When it looks like it is time to plant your seedlings outside, you will need to harden off the plants.  This is simply getting them adjusted to the changing conditions outside.  When you begin this, make sure the plants are kept in the shade for the first few hardenings, so they don't get sun-burned.  Plants should be returned inside at night.  I know it seems like a lot of work, but it will yield stronger, healthier plants.  Hardening off takes 7-10 days.

2.  When planting your tomato seedlings in the garden, make a shallow trench and lay the seedling on its side.  Bury the entire plant up to the first set of leaves...all of the plant up to these leaves are capable of producing roots.  This will greatly improve their ability to obtain water and nutrients  and provide greater yields.

3.  Once the tomato plants are in your garden they should be watered daily for a week.  They should be supported as they grow with wooden stakes or metal cages.  Use old nylons cut into strips to tie plants to supports as the nylon will not bruise the stalks.  There are also many commercial plant ties available.

4.  Caution!! Plants are very susceptible when young, to cutworms, which will cut your plants right off at the surface of the soil.  To avoid these without chemicals, simply take a strip of aluminum foil (cut up a pie plate into 2" strips) and fashion a collar that slips around the plant and gently place in the soil around the stalk.

5.  Tomato hornworms will more than likely be a problem when your plants start to fruit.  They devour the foliage and in some cases even eat new green tomatoes.  The easiest way I have found to get rid of them is to put a bounty out on them and have the kids pick them off.  A natural bacteria is also available in garden centers.  Good Luck!!!
