How to Get True Seed from Your Tomatoes
You can collect seeds from tomatoes and replant them next year, but the new plant may not be the same as the mother plant. Alainia Hagerty, owner of tomatobaby.com says putting a cloth bag around your tomato flowers will keep the seeds of that tomato true to the mother plant. The bag keeps insects out that might bring pollen from another flower or plant.

Strawberry Problems
In our strawberry bed, half of the ripe strawberries are inedible. Gardener Peter Richards explains that many of these problems are because there is no plastic mulch on the bed.
