Growing Potatoes - Top Gardening Tips

Growing Potatoes - Holiday-Proof Potato & Root Veg PlanterPotatoes are an extremely popular vegetable to grow due to the fact they are great for patios, raised beds or for planting straight into your garden.
Potatoes are grown from seed potatoes, also known as tubers and you can expect to harvest between 6 to 12 potatoes from a single seed potato.

Our Root Veg Planter is perfect for growing 4 varieties of potatoes in 1 planter. The Root Veg Planter is the perfect replacement for traditional veg pots, planters and grow bags. 


Varieties of Potatoes

As mentioned above, potatoes fall into two main types of varieties, Earlies and Main Crop. Early potatoes are harvested as ‘new potatoes’ and are ready for harvesting 10-12 weeks after planting.

These potatoes are full of flavour and best eaten soon after harvesting. Some of our favourite potato varieties to grow are:

First Earlies: Pentland Javlin, Rocket and Home Guard

Second Earlies: Maris Peer, Wilja

Main Crop: Sante, Maxine, Desiree

Late crop in time for Christmas: Charlotte, Vivaldi and Maris Piper


When to plant Potatoes

Generally, you should plant chitted potatoes between March and May - earlies can be planted earlier in frost free areas or in a polytunnel or greenhouse as early as late February.
'Second earlies' can be planted throughout March, while 'main crop' potatoes are generally planted in April and left to grow larger than small early potatoes. These main crop potatoes will be ready to be harvested towards the end of August through to October.

Christmas Potatoes

Plant potatoes in August to harvest in time for Christmas. Many mail order suppliers now sell late cropping seed potatoes. These are usually early varieties that have been held in cold storage and sent out in August. They don’t require chitting, so plant them as soon as you receive them.

These potatoes will need protecting from frosts in the winter either by putting the container in a greenhouse or covering the container with a fleece and putting them in a sheltered spot away from the worsts frosts. By a house is a great spot.

Chitting Potatoes

Chitting is a technique which encourages your seed potatoes/tubers to produce strong healthy shoots before planting them. When you chit your potatoes depends upon which part of the country you are growing in. In warmer parts start chitting in late January, however, for those in colder parts, February is the best time to chit. You will want to chit your potatoes about 6 weeks before you intend to plant them. Chitting helps your potatoes grow faster and produce potato crops sooner.

To successfully chit/sprout your seed potatoes, place them in a cool place, frost-free room with plenty of light in a clean egg box or seed tray with the rose end facing up (the end with the most ‘eyes’). The potatoes are ready for planting when the sprouts measure about 2cm long. Read more about how to chit potatoes here.

Growing Potatoes

Plant your chitted potatoes when the soil has started to warm up, usually from mid-march or early April. Start by digging a trench 7.5-13cm (3 inches deep, although the exact depth should vary according to the variety of potato you’re planting).

Potatoes can be planted in a container or out in the garden or raised bed. Always place the tubers/seed potatoes rose end up (the end where tiny buds can be seen). 

Growing potatoes in containers/ Root Vegetable Planter

Plant enough potatoes to fit the size of the container you are using. You could fit 3 in a 40cm pot, one in a 25cm pot or 5 in our Root Veg Planter.

Add gravel to the base of the pot followed by 4-10cm of compost. Place the potatoes around the edge of the container and cover with 10-20cm of the same compost.

Growing in raised bed/garden

When growing in the garden, use well-rotted manure dug into the top 30cm of soil. Plant the potatoes about 15cm deep and 30cm apart (35cm for the main crop), in rows 60cm apart.

Caring for your Potatoes

Earthing Up

Earthing up increases the number of potatoes grown from each tuber and protects them from sun exposure, which would turn them green.

When shoots are showing 10cms above the soil or compost, cover them with more soil or compost leaving 4cm shoots showing at the tip. Continue to “earth up” each time the roots are 10cms above the compost, if you are growing in a container you will ‘earth up’ until you are 4-5cm from the rim of the container.

Watering your Potatoes

Potatoes will rot if they are over watered but they do require a constant supply of water, especially when they are flowering and potatoes are forming.


Watering your Potatoes

You can also plant 3 seed potatoes in a Potato Grow Pot using multi-purpose compost and watch your potatoes grow by lifting the inner pot out of the outer pot.

After 8 weeks your spuds will be ready for picking (10 weeks if the potatoes haven’t been chitted).

Harvest your potato crops using a Potato Harvest Scoop that allow potatoes to be sifted from the soil.

Brush off excess soil, cut the top off root vegetables and wash them in a Vegetable Trug. Allow your potatoes to dry before storing in a Storage Bag.


Root Veg Planter

Root Veg Planter is a space-saving potato planter which produces healthier plants and bigger harvests than traditional pots, planters and grow bags by providing your plants with constant access to water without ever over-watering. It's clever design prevents water-logging so that you raise bumper harvests of potatoes every time.

Simply plant your seed potatoes/tubers in the base of the pot and fill the SmartReservoir and let the FeederMats in the pots pull water up to the young potatoes when they need it. Although the plants have access to water whenever they need it, the tubers are never stood in the water, so there's no risk of soggy rotten spuds and you raise bigger harvests of better tasting potatoes.
