Most gardeners plant in March, April or May, and expect a harvest about four months later, starting to dig new potatoes about two to three weeks after plants flower.
Potatoes are not hardy plants, so in general they are planted in spring from mid March to late April and can be harvested anywhere between June and October.
Planting and harvesting potatoes in Australia
In warm climates, plant potatoes between March-April. In cool climates, plant potatoes between July-August. Potatoes can be harvested between 90-120 days from planting.
Typically, potatoes are planted in March for harvesting throughout the summer and autumn months. But they can also be planted in August or September so that you can enjoy new potatoes around Christmas. But before you can plant your potatoes, the seed potatoes themselves need to be chitted.
When planting, an NPK ratio of 15-15-15 is ideal. A month or two after they've been planted, potatoes need lots of nitrogen, so a fertilizer with an NPK of 34-0-0 is the best choice. An NPK of 12-12-17 or 14-7-21 is best for the last couple of months before harvest when the plants require more potassium.
Adding organic matter will help retain moisture in the soil and this is vital for potatoes, as they demand plenty of water when the potatoes are forming, from flowering time to harvest. Potatoes also enjoy the addition of potash and blood and bone to the soil.
It has been shown that chicken manure pellets are the go-to choice fertilizer for potato farmers. Potatoes thrive in calcium-rich soil, this helps produce large full flavour potatoes. Chicken manure pellets contain up to 7% calcium. These pellets also release their nutrients slowly over 3 months.
You can grow many different types of potatoes. They usually take 12 to 20 weeks to grow depending on the potatoes you choose, so if you want to eat potatoes in the summer, plant them in early spring.
Potatoes grow best in well-drained, sandy soil. A poorly drained soil is more likely to produce diseased tubers. Have your soil tested. The ideal soil pH level for potatoes is somewhat acidic, between 6 and 6.5, but they will tolerate soil with pH as low as 5.
In regions with mild winters, potatoes can be grown outdoors and planted at the end of summer or the beginning of fall. However, hard freezes or heavy snow can damage or kill potatoes. In regions with harsher winters, you should avoid growing potatoes outdoors during winter.
Swift is one of the fastest maturing seed potatoes, and has been known to produce a good crop in as little as eight weeks from planting. Swift is easy to grow and will produce the quickest crop of new potatoes.
Do potatoes keep growing after the plant dies? Once the plant dies, the potatoes are finished growing in size. However, the skin on the potato does harden and cure to make it stronger for storage. We recommend leaving the potatoes in the ground for about 2 weeks after the plants have died off.
You can use store-bought potatoes, but they can carry diseases or be treated to stop them from sprouting. Plant your potatoes in trenches and then keep covering them as they grow until they grow out the top of the trench. This encourages better yields.
'Vivaldi' potatoes contain fewer carbohydrates than others, so make a perfect choice if you're watching your calorie intake. 'Rocket' is a first early that crops heavily, very early in the season, and produces tubers with a delicious taste and soft, waxy flesh.
Plant potatoes after danger of hard freeze in full sun. Till the ground to a depth of 12 inches, amend heavily with organic matter; place seed pieces eyes up and mound soil into hills. Space every 12 inches with rows 36 inches apart. Keep soil moist.
Early and maincrop potatoes can be sprouted inside before planting in the garden, this is known as 'chitting'
Whilst potatoes will grow in practically any soil, they will do so much better if the soil is mixed with rotted organic matter such as farm yard manure and it is loose/fine.
Potatoes grown directly into the ground will provide a better yield by weight than those grown in containers.
The key to growing potato is getting your timing right and ensuring the plant doesn't become too wet. Your potato will perform best in a spot with full sun and wind protection. Plant in a soil or potting mix that is free-draining.
As a general rule, if the plant is healthy, you can expect to dig up about five or six full-size potatoes. Every potato plant will most likely have a bunch of smaller, baby-size potatoes as well.
Radish. Radishes are probably the fastest growing vegetable in your garden, being ready to pick in as little as 30 days from planting the seeds. Their peppery flavor is a hit on the vegetable tray or added to a fresh lettuce salad.
Potatoes always do best in full sun. They are aggressively rooting plants, and we find that they will produce the best crop when planted in a light, loose, well-drained soil. Potatoes prefer a slightly acid soil with a PH of 5.0 to 7.0.
What Vegetables Like Coffee Grounds? Coffee grounds as a fertilizer can be used when growing vegetable crops such as potatoes, cucumbers, peppers, carrots, radishes, and beans. Root crops need magnesium and potassium, while nitrogen is indispensable for green crops.
Any biodegradable mulch will do, but using a deep hay or straw mulch is an especially good way to grow potatoes. They keep the soil cool and moist while serving as an obstacle course to Colorado potato beetles and other insects that travel on foot.
Potash (potassium, K) is an essential nutrient for all plants and has a major effect upon yield and quality of potatoes as well as the general health and vigour of the crop. It is involved in regulating the amount of water in the plant; in the absence of sufficient potassium crops do not use water efficiently.
