Here are some carrots I'm growing in the front half of this self-watering container. Yellow beets are in the back half. I started these pretty late, but I think they'll mature before frost.

Next year, I probably won't plant carrots and beets in the same container since the beets tend to shade the carrots.

There have been some bugs on the carrots - or actually on the soil around the carrots - that I haven't been able to identify. They don't seem to be doing any harm, so I haven't done anything about them yet.

The variety of these carrots is 'Red Core Chantenay.' At maturity, the roots are 5-7 inches long, so I think this container is deep enough. They're supposed to store well, so that's an added plus.

Other varieties of carrots that are on the shorter side (and therefore good choices for container gardening) are: 'Oxheart', 'Parmex', 'Redland', and 'Kinko'.

Here are the basics on growing carrots:

General Info:
Carrots are an excellent source of beta carotene, which your body uses to make Vitamin A. During germination and growth, carrots like consistent moisture, so they are a good choice for self-watering containers.

Location: Prefers full sun, but will grow in partial shade

When to Sow: Direct sow from early spring until the middle of the summer.

Planting Depth: 1/4 - 1/2"

Plant Spacing (After Thinning): Different according to variety. See seed package.

Soil Temperature for Germination: Usually in the range of 50 - 80 degrees. Some varieties need a little warmer soil temperature before planting. For example, 'Scarlet Nantes' germinates at soil temperatures of 60 - 80 degrees.

Days to Germination: Depending upon the variety and soil conditions, can be from one week to three weeks.

Days to Maturity: Varies. Usually, at least 65 or 75 days.

Tips: Carrots can be eaten as soon as the roots become fully orange. Harvest early for sweet, tender carrots that are very nice in salads. Harvest later for a larger size that can be cut up and cooked, or used in salads.
