How to Grow Carrots on a Balcony

by balconyboss

Carrots are a very popular root vegetable well known for their vibrant color and their versatility in the kitchen. Carrots can be enjoyed raw or cooked and make for an ideal ingredient on both sweet and savory meals. The following guide will help you learn how to grow your very own carrots on your balcony.

Before Getting Started

The following is some essential information you need to know before growing carrots on your balcony.

  • Climate: Carrots thrive in moderately cool, but not cold, temperatures. They are best grown in the early spring and fall, when the temperatures will hover around 55 degrees at night and 65 to 75 degrees during the day. They should not be grown in the summer, as high temperatures result in low quality carrots.
  • Sunlight: Carrots will need about 6-8 hours of direct sunlight. They should be planted in an area that will be shaded in the afternoon or in an area that can be covered during the hottest time of the day.
  • Planter: You will need a planter that is at least 10 to 12 inches deep. Look for a wide planter, as this will give your carrots room to grow and will likely result in a better carrot harvest; at least 18″ in diameter, if not larger.
  • Indoors or Outdoors? Carrots are surprisingly easy to grow indoors; they can often thrive indoors because they are not exposed to the exceptionally hot temperatures outdoors, which can result in low quality carrots.

What You’ll Need

The following are some basic supplies you’ll need to grow carrots on a balcony.

  • Carrot seeds
  • Soil
  • Container (at least 10-12 inches deep)
  • Fertilizer (low nitrogen, high in phosphorous and potassium)

Step by Step Instructions

The following will help you get started with growing carrots on your balcony.


1. Prepare your container

First, prepare your container with well-drained potting soil. Carrots need soil that is well-drained because their roots need lots of room. Always choose a pot with drainage holes, since carrots need to be watered regularly.

2. Plant your seeds

Carrots should be planted at least 2 inches away from each other, or 4 inches away if you have the room. Plant them about 1/4 inch deep and cover with soil.

3. Maintain

Maintain your carrot plants by watering them regularly. The soil needs to be kept slightly moist, but not damp, at all times. Do not let soil for your carrot plants dry out completely.

Growing Notes

  • Water: Always check your carrot plant soil before watering. Stick a finger an inch into the soil–if it is moist, there is no need to water. If it is drying out, then you should water. If you measure your water usage, keep it to about 1 inch per week when the plants are young and 2 inches once the plants begin to mature.
  • Growth: It will take 70 to 80 days for carrots to grow.
  • Maintenance: Regularly check your carrots to make sure they are not too dry or too moist. If they are too dry, the carrots will be stunted or not grow. If it is too moist, you increase the chance for root rot. Fertilize your plant 5-6 weeks after planting.
