Now is the time to start saving those seeds.
If you have carrots that have gone to seed, shake the seeds onto a piece of white paper and place the seeds in an envelope.
Tomatoe seeds are collected by cutting tomatoes in half and squeezing the seeds and pulp into a dish and letting it sit for a few days. Wash the seeds and dry them. Store in an airtight container
Squash is out and going crazy. Try some wierd and wonderful varieties that you will find at local farms and farm markets. Just wash the seeds and allow to air dry.
Beans, beans and more beans. I have them coming out of my ears. Allow the pods to dry on the vine or pick the plump pods and store in a well ventilated place. Once, the pods are dry, the seeds are ready to collect. Save the pods for your compost. Be sure to cut them up.
