List of all plant growing information
Potatoes
Growing your own spuds is easier than you think with these unusual potato varieties. They are hardy and easy to grow, with a wonderful flavour whether eaten 'old' or 'new'. Expect a yield of approximately ten times the amount you plant. In order to achieve your own year-round planting stock, save tubers from your harvest in a cool, dark, dry place and replant as suits your climate zone. We will automatically substitute a different variety when sold out, unless you indicate otherwise.
Important
Recommended planting time: Potatoes can be grown in many months of the year, depending on whether the garden receives frost, as potatoes are frost-tender. Potatoes need 60 to 90 days frost-free to be successfully harvested; potatoes harvested early as 'new' potatoes do not store well. In northern NSW and QLD one of the best planting times is March - April, as the soil is warm, growth is rapid and there are generally less pests. For frosty areas, potatoes can be planted in early spring, shortly before the last expected frost.

Potato varieties can be either determinate or indeterminate, just as tomato plants are. The big difference between the two types is whether you need to mound the soil or not. Having said that, the majority of types available to the home gardener are indeterminate and so do need mounding.

Determinate Varieties
These types produce tubers in one layer just below the soil surface and so do not require mounding of the soil around them. They are usually less productive than indeterminate types but do produce spuds earlier, in about 70 to 90 days. If you live in a very cold climate these are the best choice. Plant determinate seed potatoes about 10 cm deep and mulch well. Available: 'Kipfler', 'Purple Congo'.

Indeterminate Varieties
These grow in multiple layers, so it is important to keep mounding soil around the plants, to give you the best yield. Indeterminate potatoes can take longer to produce a crop, about 80 to 120 days. Best preparation is to dig a shallow 20 cm x 20 cm trench, then plant indeterminate seed potatoes about 10 cm deep and progressively fill in the trench with the soil as they grow. Only mound spuds to a maximum of 30 cm above the original soil level. These are also the best choice if you are growing spuds in a tyre tower or potato bag.
Indeterminate types include: 'Desiree', 'Dutch Cream' 'Sebago'.

Sweet Potato
Ipomea batatas
Sweet potatoes are vining plants with attractive lobed leaves, pink morning-glory type flowers and tuberous roots. They are a 'must have' vegetable in warmer climates as they are so easily grown, highly nutritious and can be used in wide range of recipes. The vines are vigorous so space is needed. They do best in areas that are frost-free for at least 5 months with warm days and nights. In cooler areas wait for the beginning of the warm weather to plant. Sweet potato was domesticated in Peru about 8000 years ago and slowly spread through South America. Research published by the National Academy of Sciences has now demonstrated that Polynesians journeyed to South America and brought home kumara, long before Europeans even reached the South Pacific. In New Zealand sweet potato is known as kumara and both the pre-European Maori types and those introduced by Europeans are grown. Sweet potato prefers a rich, fertile, well-drained soil in full sun; space plants 35 cm apart. In subtropical and tropical areas sweet potato can be planted all year round.
