Give them plenty to drink: Especially during germination. Keep seedbed evenly moist, but don't drown them.
Keep them warm: Pumpkins need plenty of sun and protection from the wind.
Choose the biggest pumpkin on each vine and get rid of the others so it grows like mad.
Pumpkins love sun but not too much. In the mid-summer heat they like a little light shade.
In the autumn, cut the pumpkin off the vine, leaving 10-20cm of the stem attached. Lift the pumpkin into a sunny, sheltered spot to ripen.
These big pumpkins are not for eating - unless you're a pig.
On Saturday April 5, Mitre 10 will have a pumpkin weigh-in, with judging at 1pm. There will be prizes for the biggest, ugliest and best-dressed pumpkins. You can find out more at mitre10.co.nz, and a whole lot of others things as well, such as how to make a raised garden.
Talking about raised gardens, once you have the children excited about big pumpkins, start a garden (raised gardens are easier to dig with a plastic bucket and spade).
The first thing about starting a children's garden is that it should be proportional to the size of the child - small - and it should be full of interesting plants that are easy to grow that they want to eat (such as lollies and icecream).
Pretty much the same rules apply to a childs' garden as for a big-person's plot. Good fertile soil, in a warm sunny spot, and access to water.
The trick is to get children involved from the very start (which is where the big pumpkin seeds come in). That includes talking about what sort of garden you should have, how big it should be, selecting the timber for the frame, putting down the weed barrier, dumping the soil, making compost, selecting what to grow and where, when to plant, when to pick, and best of all how to prepare it all for a yummy meal.
The garden only needs to be about a metre or so square, maybe a little more, so make the frame about a metre by a metre - or make it long and narrow (a couple of metres by half a metre, but depending on what spare - free - timber you can locate), so little hands attached to short arms do not have a problem reaching in. You could also use edging such as stones, logs, bricks, tyres and the like if you don't have any timber handy.
Use soil that is light and easy to work. Mix in some fertiliser such as sheep pellets - but, children, no putting in your mouth please.
A childs' garden should be fun as well as a productive, so we like the idea of planting things in addition to vegetables. Big, bright, happy, sunflowers are fantastic.
