Question 1

What is the most important thing to get right when growing root vegetables in pots?

Accepted Answer

Soil texture. Root vegetables need loose, deep, stone-free growing medium to push downward without obstruction. A 50% cocopeat, 30% vermicompost, 20% garden soil mix in a container at least 10-12 inches deep will give you straight, well-formed roots. Compacted or heavy soil produces stunted, forked, and misshapen vegetables regardless of everything else you do.

Question 2

Can I grow carrots on a Mumbai balcony?

Accepted Answer

Yes, but timing is critical. Carrots need cool weather — sow seeds in October or November for harvest in January or February. Temperatures above 28°C cause poor root development and bitter flavour. Use Nantes or Chantenay varieties which are shorter and better suited to container depth than long varieties bred for deep ground.

Question 3

Why did my radish produce big leaves but almost no root?

Accepted Answer

Two common causes: too much nitrogen in the soil (pushing leaf growth over root development), or insufficient sunlight. Radish needs 6 hours of direct sun. Switch to a balanced mix with vermicompost rather than nitrogen-heavy fertilisers, and ensure your container is in the brightest spot on your balcony.

Question 4

How deep must my container be for root vegetables?

Accepted Answer

Radish and turnip need at least 10 inches. Carrot needs 12-14 inches. Beetroot needs 12 inches. The container can be any shape — a deep grow bag works as well as a rigid pot. Depth is non-negotiable because the root literally has nowhere to grow if it hits the base of a shallow container.

Question 5

When is the right time to harvest root vegetables so they do not become woody?

Accepted Answer

Track your sowing date and start checking at 80% of the expected days to harvest. For radish, that means checking at 24-25 days. Pull one vegetable as a test — if it is the right size, harvest the rest within 3-4 days. Do not wait for all vegetables to reach maximum size simultaneously. Woody, cracked roots almost always mean you waited too long.

Question 6

Can I eat the leaves of root vegetables?

Accepted Answer

Yes — and this doubles your harvest value. Radish leaves are slightly peppery and excellent in sabzi or paratha stuffing. Beetroot leaves taste like spinach and can be used the same way. Carrot tops are edible but slightly bitter — use sparingly in soups or chimichurri. Harvesting some leaves early does not significantly harm root development.
