anyone into raised bed gardening ? need tips on starting one.

Has anyone built a raised garden bed? I need help in figuring out the best soil to put and also how to protect crop from squirrels and other critters.

The house we are renting has a decent backyard but the soil is really bad. I've grown some summer crops such as tomatoes, brinjals, zuchhini, beans and cucumbers with success in large pots this summer. But the quantity that is grown in pots is small, I want to build a raised garden bed to grow winter veggies since the weather here is so mild during winters (carrots, beets, spinach, lettuce and radish).

Please let me know !

Thanks,

Pooja

 

Thx Rakhi. Went over to my nursery today and they told me to use this.
