How Long Does It Take Potatoes To Grow?

How long depends on the variety of the potatoes you seed.  This may sound confusing but we will explain it below.  There are 3 main types of potatoes with each having a different maturity time.

  • The Early Varieties have shorter maturity times and are fully grown and ready for harvest in less than 90 days from seeding.  This variety is best for cool regions to help you harvest an early crop. Some early varieties include Red Norland and King Harry, which has purple skin and is resistant to Caribe, potato beetles.

  • The Mid-Season Varieties reach their maturity in about 100 days from seeding and are best for planting in warm areas.

  • The Late Variety produces enough potatoes to take you through winter and they mature in about 110 days.  They are ideal for warm areas and store very well for longer periods.

Generally, it takes about 80-110 days for your potatoes to reach maturity.  You can start harvesting your potatoes as soon as you notice the first large enough tubers.  You do not have to wait for the potatoes to reach their full size.  The small young tubers are tender and tasty too.

Useful Tips To Follow On How To Grow Potatoes

Regardless of what variety you choose to grow, there are few growing tips you should follow to ensure you get a good harvest.

Get Certified Tubers

Each potato tuner equals a potato seed!  Your potato harvest will grow to form the tubers you plant in the ground.  You can use any tuber, yes, but if you want a good harvest then go for certified tubers.  These tubers from a local nursery are ready for planting and will easily sprout. Potatoes sold in the Supermarket are treated against sprouting.  And even if they sprout and you grow from them, the potatoes will be weaker and prone to diseases.

Pre-Sprout Your Potatoes Indoors

If you want your crop to start well, plant pre-sprouted potatoes.  To pre-sprout, place the tubers in a warm well-lit room for about 5 weeks before planting.  You will notice sprouts beginning to come out from the tubers.  Planting pre-sprouted potatoes give you the advantage of harvesting at least a month before the standard maturity time.
