October in the Garden

Get in shape: Now that spring’s fully sprung and evenings are longer there’s plenty to do outdoors. Planting,weeding (keep one step ahead by getting them before they seed) and of course covering the soil with mulch (save yourself some watering), and also to prevent weeds and erosion, feed plants and worms, and hold moisture.

Labour Day is of course the traditional time to plant summer veges and what better place than at Paekākāriki School Plant Sale: 9-12, Saturday October 22Get your local heirloom tomatoes, herbs and perennials, natives and more while also checking out the coffee, food and music. All proceeds support the school garden.

Straw bales: If you missed making loads of compost last autumn, it’s not too late to have a garden this summer. Making your own compost is free of course, but if you’re thinking of buying in compost or topsoil, consider instead a straw-bale garden. This is also a good way to start off new raised bed gardens, instead of trucking in a lot of soil or compost.

Straw bale gardens can be built inside raised bed frames- especially useful when, as here, filling the bed with soil would involve a lot of barrowing.

Straw is not cheap, but it’s cheaper than soil and easier to cart around. Ōtaki’s Farmlands has bales of barley straw for $14. At Pauatahanui’s Rural Trading Post they’re $18, but that includes free delivery.

Straw bales take at least two weeks to prepare before they are ready for planting – they need to be kept thoroughly saturated, with manure or blood-and-bone added to begin the rotting process. By the end of the season they’ll have broken down into good quality compost.

1. Choose your spot: sunny is best. A straw bale garden can be on top of concrete or soil but use weed mat/carpet underneath if building on weeds or kikuyu. Bales can also be placed inside raised bed frames.

2. Place bales upright (strings on side), leaving strings in place.

3. Stake or support them with bricks- you’ll be glad of this later.

4. Water thoroughly – this can take a while. They need to be wet to the core. Make small pockets in the top and add compost/ manure/worm casts, then water that in too.

5. Liquid feed: Every day, water on some liquid feed: seaweed or comfrey tea, liquid blood-n-bone, worm tea… If you want to grow fruiting plants like tomatoes, make sure to also add something with potassium (eg wood ash).

6: Keep them moist and keep an eye on your bales. When they heat up and the insides start to break down, they are ready.

7. Plant: Plant seedlings into a hole, adding sterile compost or potting mix. To sow seeds, make a 5cm layer of potting mix on the surface. The sides of the bale can also be planted into.

 

WORKSHOPS AND EVENTS

Kumara growing at Te Kura-ā-Iwi o Whakatupuranga Rua Mano in Ōtaki - black plastic is being used to warm the soil.

 

See straw bale gardens in action- and more:

Kāpiti Community Centre: With demand increasing, the Monday morning workshops at are going fortnightly from now until December. Each session will give you practical skills and highly localized expertise to garden well here on the coast. The workshop on 3 October will include building a straw bale garden, and taking cuttings.

 

Matai Rd Community Garden: Next workshop is Sunday October 16, 1.30-3.30pm, we will be looking at composting and also setting up basic, efficient irrigation (easiest done at planting time rather than threading it through the bed later!).

Keep up to date through their website or facebook page

 

Ōtaki College Garden: Friday afternoons 3-4pm, during the school term, are a good time to come and see what’s happening in the college’s community garden space. Straw bales, composting, no-dig techniques and more.
