Something else I never heard of before. Came in the mail this AM.
"Are you planning to grow tomatoes next year? If so, you might want to
consider grafting some of your favorite varieties onto a vigorous
rootstock. Grafting is an increasingly popular technique among tomato
growers who have had disappointing yields and disease problems. It's
especially helpful for heirloom, greenhouse, and hoophouse tomatoes.
Grafting is not difficult, and Johnny's has the supplies and information
you need to be successful. The procedure is straightforward: You start
seeds of both the rootstock and the scion (the variety you want to
fruit) and grow them until they are 3-4" tall. Then you cut the
rootstock and scion stems at the same angle with a sharp razor blade,
and attach the scion to the rootstock plant with a grafting clip or
piece of tubing. Experienced growers say they can graft 100 plants per
It's important to note the differences between the two rootstocks we
offer. Maxifort is an extremely vigorous rootstock that should be used
for greenhouse tomatoes such as Arbason and Trust. It should not be used
for heirloom tomatoes because it will produce too much vegetative growth
at the expense of fruit production. For heirlooms, choose the somewhat
less vigorous rootstock Beaufort."
