Gardening in North Otago March 1st 2016






Autumn begins: "Ahhh this warm ripening season I love, long shadows, low sun in Cornflower blue sky's above". ( At this mellow time of the year the poet in me emerges!!) I am still cut, cut cutting back plants that looked stunning through summer but are now just tied and straggly like bush lavatera, mignonette, lavender tops, geraniums, they will all leaf up again to go through the winter. I am still seed collecting, there are so many ready now, I plant a few now but save most to sow in spring. What I am planting now are lupin, Iceland poppy, pansy, pollyanthaprimulaaquilegia (Grannies bonnet) and ageratum ( snapdragon) wall flower, stock, Virginia stock and sweet-pea. if these sunny days keep up they should all be up and ready for me to prick out and and plant into containers where they will continue to grow and harden off a little before the danger of hard frost. If some of these seedlings grow big enough to reach bud stage I will plant into the garden but most will need to be carried over until the ground warms up again in spring.( Sweet pea seeds should to be planted straight into the garden now, they will pop up and hold over the winter then as soon as the ground starts to warm in August they will take off and flower early ) This week the hedge trimmer has been out again because with the favorable conditions we have experienced this growing season.some shrubs in our garden have out grown their space. 
Autumn is said to be the best time to plant conifers, http://www.conifers.co.nz/ there are such a lot of different types on offer now and I consider these contribute to the bones of the garden. Tall narrow conifers planted in groups give larger gardens a vertical push and formality. Read labels carefully they will give you the height and width for the first ten years, after that they do keep growing and can be removed if they start to look untidy but most ornamental conifers look wonderful for years and years. 

Compost:This is an excellent time to start building a new compost heap and get it heating up before winter.http://freshorganicgardening.com/learn-to-build-a-compost-pile/

Lawns. This is said to be the best time to sow a new lawn,because perennial weeds have slowed down, the ground is nice and warm as are the nights and if the moisture is kept up grass seed will be up in no time. I have been spot spraying the flat weeds in my lawns and when we get rain again I will apply grass grub granules, as this is the time to do this. 

Vegetables: What a great year for produce it is with so much ready to use, parsnips, beetroot, carrots, potatoes, corn and pumpkins scrambling all over the place. Keep planting in rotation, leaf veg where root veg has been,
It is a good time to sow Root plants like Asparagus , Beetroot , Carrots , Chives , Leeks ,Onions , Parsnips , Shallots , Spring Onions.  When potatoes are dug they need to be kept in the dark or they will go green. I take what I need from a dig and leave the rest in the ground until needed. When the time comes for you to store them there are products which will inhibit sprouting, but many gardeners avoid chemicals near food so I will once again mention a natural alternative with you. Layer the stored potatoes with dried sprigs of rosemary, sage and lavender, the essential oils given off by these herbs not only inhibit sprouting, they will also help to keep the tubers free from bacterial soft rots. 

Fruit: Apples, quince, plums, walnuts and late peaches so much at once! the birds must be overjoyed by their feasting and the rats / mice will be waiting patiently for the nuts and sun flower seeds to ripen, such abundance! Cover grapes from those waiting birds.

Cheers, Linda

Gardening in North Otago 24th.2.2016

This real summer weather continues and the warm days are a joy to garden in, all that is needed is one good shower to keep the moisture levels up. Keeping the water up here in this garden is top priority, dragging hose's from one garden to another with a small determined dog still pulling the hose end the opposite way!! Yes, I know he thinks it is our special game and my verbal responses like Scruuuufffff...... seem to be the attention he craves from this one sided game. 

As well as hose dragging I have been cleaning paved areas and structures with a water blaster, what a difference once moss, liken and dirt have been removed, it sure beats sanding for ages on wooden seats and structures before painting.
Keep tidying up the fluffy new growth on hedges, the sharp neatness really stands out among the full summer growth. 

I thought it might be a good time to mention the pruning and shaping of shrubs that have flowered on previous years growth like rhododendrons, camellias, azaleas, ceonothus, forsythia and coleonema (breath of heaven) but only if they need to be trimmed and shaped to reduce their height or width. This should always be done while there is still enough growing season left for them to make new growth and harden off well before temperatures plummet. In colder areas like Kurow this trimming should be done as soon as flowering has ended, with the exception of hydrangeas you can leave the old growth on through the winter to protect the new shoots then prune in Spring when they begin to shoot.Also this is the time to cut back natives like pittosporums and hebe's as they must have new growth hardened before winter, if you do intend to shape them be quick or leave them until after winter. 
I am also working my way round mature camellias and thinning them out, there should be enough open spaces for a bird to fly through to let enough light in to encourage the best buds for next spring. And as time allows the removal of seed heads from rhododendrons is recommended, especially on newly planted rhododendrons to encourage new plant growth. There is a place on the stem where if bent will snap the seed head clean off without damaging the new buds, it dose not take long to discover where this point is.
Seed collecting starts now for me, lupins, mignonette, poppies, dianthus, any plant that is needed again for next spring/summer. 
I left a clump of pansies to make seed after flowering, it has now surrounded itself in a multitude of seedlings for me to pot up and grow on. The original clump is now cut back and putting on new fresh growth. 

Ornamental grasses have finished making seed and can be cut back now before too many of the seed heads float about the garden and germinate, cut them well back and they will soon fluff up again to waft about in a breeze.

Lawns.
With all this heat lawns are suffering and begging for the next shower, I notice even the lawn weeds are struggling which means lawn weed spray would work a treat while weeds are thirsty, spot spraying on a dull day is kinder to worms and bee's than full lawn coverage on a sunny day.

Vegetables.
Keeping water up to veg Gardens is on going, my raised beds dry out in no time so good soakings are require rather than the sprinkler now and then. I find myself wanting cooler nights for the sake of vegetables which is a bit on the sad side considering it is for once a fantastic summer.
If you are prepared to keep the water up keep planting in rotation, leaf veg where root veg has been, the warm soil will keep germinating and producing until the first frost.



Cheers, Linda.

Gardening in North Otago 17. 2. 2016

Warm days and nights, what a wonderful warm summer we are enjoying now which means the hoses are out again to revive plants while they cope with some very intense heat. Early morning is a good time to get moisture down around roots, for those who would not have time to water before work, set the hose up ready to turn on first thing in the most needed areas to give a good soak before you leave. Evaporation from leaves is a problem especially in shallow rooted rhododendrons, camellias, azaleas and tall plants where moisture needs to reach a distance.  
My wheelbarrow has been busy this week, with so much growth the cutting back seems endless, any plant or bush that has finished flowering needs cut back to where the new growth is starting to appear, hebe's finish flowering and make seed very quickly, cut all those seed heads and stems off, the bush will look bare but will soon push out new growth and stay the size you require it to be.  Photinia bushes and hedges trimmed now will reward you with new bright red foliage in April / May and into the winter.
Keep the water up to roses, if roots dry out between watering's they will respond with yellowing leaves, rust and black spot, don't be alarmed these are usually old leaves,  remove them before they fall and spread disease into the ground even if it means removing most of the bush, new leaves will soon take their place.
If you have buddleias, ( the butterfly bush) tall thin arching branches with grey/blue leaves and lavender, purple or pink long narrow flower heads, cut them back almost to the ground when they have finished flowering then again at the end of winter. They grow back very quickly and are best grown at the back of a border.
Garden centers are full of lovely bedding plants and shrubs right now, read labels regarding where to plant, sun/shade, with shrubs frost tolerance is important, I have noticed tender shrubs not suitable for hard frost areas on offer, they look nice but have probably been grown under cover and would not cope with frosts if planted out in the open, in pots under cover they should be ok.
Lawns: I spot sprayed flat weeds and clover in the lawns this week, with worms in mind I never cover a whole lawn in spray.
The evidence of grass grub is noticeable in tree shaded areas now, the adult brown beetles tend to lay eggs under the trees they feed on. There was an absence of product for a couple of years but I see there are choices back on the market. Eggs of the NZ grass grub are laid in the soil during summer; normally hatching after about 2 weeks. The small larvae feed on the grass roots until spring, infested grass dies off leaving a dead mat. The grubs are usually found about 15 cm below the soil surface and control of the grub requires getting insecticide to this level in the soil. Treatment is most effective from February to March.
Fruit: 
With the sunny days fruit has been ripening, I have never seen our apricot tree so laden and have been picking bucket fulls for jam, sauce, freezing and giving away. Late peaches, apples and grapes need water kept up to them.

Vegetables:
Keep planting all vegetable plants in rotation...if you now have a space where root veg were growing fill it with leafy veg and visa versa. Any spaces you have vacant fill with a green crop, wheat, barley, oats, blue lupin or mustard seed. Dig into the soil before it flowers. The humus created from a green crop is about the very best thing you can do for tied soil.

Cheers, Linda.

Gardening in North Otago 9 /2/ 2016

We got our share of sun last week and gardens responded by lifting blooms and pushing out buds.
I must comment on how pretty our town is right now with beautiful blue agapantha's cooling warm sunny gardens and complementing the second flush roses and vibrant dahlia's, a special mention to the colorful Council gardens and pretty hanging baskets.

I am still cutting back and dead heading so much after those wet soggy days, it all has to go if it has died back to encourage new fresh growth.
February is a good month for taking cuttings and propagating your own plants because by late summer the soft new spring growth has hardened and the cutting is less likely to lose water from the leaves. Semi-succulent plants like geraniums (Pelargoniums) or impatiens are easiest for beginners, but many common shrubs such as abeliabuxus, lavenders,camellias, azaleas, fuchsias and hebe's have a relatively high success rate, it is all about keeping the cut pieces alive while they develop their own new roots. Professional nursery people grow cuttings in glasshouses where they’re regularly misted with fine sprays of water. But there are lots of techniques that can help a home gardener to achieve success. Take cuttings early in the morning, while it’s still cool. Choose tip pieces that are about 100- 150 mm long. Pop immediately into water.Working in the shade, fill pots with Seed Raising Mix / crusher dust and water well, allow to drain, trim the base of the cutting so that it ends just below a leaf node (which is where the leaf  has been attached to the stem). Remove bottom leaves, leaving a few at the top, large leaves can be cut in half. Dip the base of the cutting into hormone Gel or powder then poke into the mix, a 150mm pot can hold about six cuttings. Place pot in a lightly shaded spot and cover with plastic wrap held above the cuttings, (wire hoops made out of an old coat hangers work well ) keep moist and Check regularly and after a couple of months gently move the stems to feel if they’re firm. This will mean roots have started, plant in individual pots when roots are established.

Hedges here got a light tidy up last week, (not the buxus, too much heat in the sun to trim them just now.) but ok for all other hedges that have put on unwanted new growth.
 , they are in the shops and they want to be in the ground now. A bulb comes ready-equipped with food and the promise of a flower and I feel bulbs look best planted in groups. The one thing we can hold off from at this time of the year is planting trees and shrubs, unless you are able to water daily, no reason to not choose and buy trees and shrubs when you see them on offer now, store in light shade while still in growing bags and keep the water up to them until planting time in mid to late autumn. 

Lawns: During that last rain I fertilised lawns and the lawn weeds responded well along with the grass, hydrocotyle is thriving here this year so I sprayed with hydrocotyle spray which also deals to a number of other lawn weeds including clover, sorry worms!
 
Fruit: Feed citrus trees with citrus food and spray any scale you notice with winter oil. 
My grapes have scummed to botrytis again this year, I removed a lot of shading leaves to let what sun there was in during those overcast days but mindful at the same time not to expose them too much to sun burn. It if they are affected too badly it looks like I will be making late season sweet wine, in wine making circles Botrytis cinerea is a fungus that is referred to as "The noble rot"which zaps most of the moisture from the fruit, late harvest grapes are more similar to raisins than plump grapes,\.

Vegetables: Keep sowing veg seeds like carrot, beetroot, parsnip, spring onion, brussels sprout, keeping onions and lettuce because there is plenty of growing time left  to germinate seeds before the frost start again. Dig and store potatoes if you feel they have been in the ground too long, I was doing this the other day with the unwanted help of scruff the dog...I am sure he thought I was digging up ball's to be carted off ready for throwing! 
A generous amount of fresh mixed herbes cut and placed on top of dug potatoes is an old garden tip for keeping them from rotting and sprouting. I use thyme, rosemary, sage, marjoram and mint.

Cheers, Linda.

Gardening in North Otago February 9th 2016

February, Children back at School, ok, now we really are into this new working year!!!
So good to have the sun back after all those dull, damp days, however the dullness did not stop green growth it was the flowering and fruit ripening that suffered, mushy rose buds and blooms, mold on grapes and strawberries and green, tomatoes, apricots, peaces and nectarines......sound about right? remove any affected blooms and fruit because fungus will spread especially in a glass or tunnel house.

It's the right time from now on to plant large flowering (hybrid) clematis to get roots established before winter.
Fungus spray on roots and growth at planting will help eliminate the wilt problem some clematis suffer from at planting time.When planting try not to disturb the roots and sprinkle a little lime around the drip line to sweeten the ground. There are some stunning hybrid clematis on offer, huge or delicate flowers, in vibrant shades that to me have a tropical look climbing and spilling through gardens, I have a stunning claret red one flowering now and scrambling up over a structure. I forget about this one every year until it's blooms to surprise and please me.

Spring bulbs, strange I know to think about Spring but wanting a spring bulb display starts now. Clumps are much more effective than one planted here and there, so if you have two or three daffodils or tulips scattered about your garden now would be the time to dig up same bulbs and plant together for maximum effect.

Continue dead heading dahlias and petunias to keep them bushy and flowering longer, remove stalky old growth right back to where the stem is plumper. 

Keep trimming hedges as they put on soft new growth and either compost the trimmings or scatter them around the garden, they are soft enough to break down at this time of the year.

Lawns
Mowing, mowing, mowing the lawns are so lush and green for this time of the year and clippings used as mulch have given our garden continuous humus as it is breaks down, I fertilised lawns during the rain which adds to the nutrients for gardens and compost.
I haven't seen many brown grass grub beetles as yet but they are more noticeable in new gardens with young trees. We was horrified when our garden was young and all the new trees were devoured by those night beetles but the leaves soon grew back again and the trees grew on to be the beautiful bones of the garden.

Vegetables:
plant, pick and enjoy.
