I understand that Ace 55 tomatoes are low in acid. Is it unwise to use them for canning even if Lemon Juice is added?
Rate This FAQ
In the 1980's several researchers studied the effects of cultivars on final acidity of canned tomatoes. Essentially, they found that the cultivar (even ones described as "low acid") did not appreciably affect the final pH when USDA recommendations to add lemon juice or citric acid are followed.
So, the short answer is that it is safe to use the Ace 55 cultivar (or other "low acid" tomato cultivars) as long as the standard USDA recommendation for adding acid is followed:
Acidification: To ensure safe acidity in whole, crushed, or juiced tomatoes, add two tablespoons of bottled lemon juice or 1/2 teaspoon of citric acid per quart of tomatoes. For pints, use one tablespoon bottled lemon juice or 1/4 teaspoon citric acid. Acid can be added directly to the jars before filling with product. Add sugar to offset acid taste, if desired. Four tablespoons of a 5 percent acidity vinegar per quart may be used instead of lemon juice or citric acid. However, vinegar may cause undesirable flavor changes.

- I have some shrubs that have been dying off in a wierd manner. Just sections at a time will completly die in a matter of a day or so, not even time to try and treat it. There are no outward signs of bugs and the rest of the shrub will be perfectly healthy. It has done this to more than one of my shrubs and also done this to more than one kind of shrub. It started last summer where I lost part of a couple and one hole shrub. I thought I had it taken care of by the end of the summer but when I mowed last week for the first time I noticed I have almost totaly lost another and there are spots on some others. The plants have been here for as many as 10 years or so and are very well taken care of. The only thing I can think of is about 3 years ago I put new plastic down and new bark, could the new plastic cause this.

- I have 4 lovely crenshaw melons on my home garden vines -- 1 large, 2 medium, and 1 small. None of them have gone yellow/white yet! We survived the snow flakes last weekend (I covered everything), but I see we are about to get another "hit" this weekend! Is there ANYthing I can do to speed up their ripening?? I have cut back my watering of the vines, but sprinklers still go on automatically in the morning. Would any of the "usual" things people do to ripen melons indoors (paper bags, put them with a banana, etc.) do any good while they are still on the vine?? From everything I have read, if they are picked while they are still green, they will never ripen -- is this true? If I keep them well covered during our few nights of 32-33 due this weekend, will they survive on the vine to ripen?
