Cucumber is another fantastic plant to grow in March. For this, you'll need a large pot or a grow bag. Sow the seeds 1 to 2 inches deep. It needs support, so use a stick or a net for the vine to climb. Water it daily, but don't overdo it. In about 35 to 40 days, the cucumbers will be ready, and you'll have fresh, organic kheera right at home!
