Gardening in North Otago 18th September 2010

The ever changing weather of spring certainly came into focus this week, for me it has been on again off again frost cloth.
In the garden
I have been enjoying planting out bedding plants and putting the finishing touches to new garden theme designs this week. I think every gardener enjoys trying new plants and colour combinations. I had a large clump of lambs ear growing in my rockery which did not need to be so large so I dug half of it out and broke it up into single plants to use around the border of a garden and as silver drifts in amongst low annuals.Silver is a shade to use as a break between strong and soft shades, will grow in sun or semi shade and lambs ear has the added bonus of being an interesting texture as well.

Keep an eye on seeds which have germinated, up until now I have had mine under frost cloth and looked at them only occasionally to see if they had struck. This week I noticed they were well up and in need of thinning out and regular watering.
I thinned them out by transplanting some like Pansy and lobelia which have shallow roots into deeper seed trays and those with longer deeper roots like lupin and poppy into their own individual small root pots. The shallow rooted plants transplant well into the garden or baskets from a tray but it is best to have a well developed root ball attached to the stronger deeper rooted seedlings when planting out.

Baskets and pots need to be thought about now, again use only shallow rooted plants for baskets like pansy, lobelia, small type petunias, Virginia stock and nasturtium with lots of slow release fertiliser and water Chrystal's to keep them going.
With pots, the roots of what you want to plant will determine the size and depth of the pot. Potted roses need a deep pot which will not heat up and cook the roots at the height of summer. Tin foil around the inside of a pot before filling,( shinny side facing out) will help keep roots cool for roses, camellias, azales', hydrangeas and small trees & shrubs. All potted plants need excellent drainage and a consistent supply of food and water. if a potted plant is left to really dry out before each watering it will never thrive and look lush and healthy.

Now is the time to take tubular begonias out of dry storage, I see mine are starting to sprout a little. I have been cutting large tubas with a sharp knife into smaller individual pieces each with a noticeable shoot ready to plant into baskets and containers.
The showy red flamboyant begonias become nice big tubas in time and by cutting sections off them each year you will achieve a nice boarder of them in no time. It's best to lift them at the end of their growing season each year because like dahlias they can rot in really wet ground like it has been this year. All begonias love any fertiliser with a seaweed of fish content.

I have just planted wild flower seeds thickly into big plastic containers which I plan to use as gap fillers in my long perennial boarders once Lillie's and other spring and summer flowering plants have finished. I am wanting these flowering blocks of mixed wild flowers to last right through until the beginning of next winter, which they will do if I keep dead heading them. Mixed wild flower seeds can be bought

Roses are really leafing up now and the warmer it becomes the more aphids ( green fly) will be about, aphids settle on the top new growth of rose bushes and are easily visible on new small leaves for you to dispose of them by removing with finger and thumb. I leave spraying until leaves are well grown and and hardened up a little.

New lawns sown now on the coast and as soon as we have a few nice sunny days in a row to warm the ground up the grass seed will strike, as I have mentioned before seed must be sown thickly in spring to beat the annual weeds.
Keep the mower blades up when cutting spring grass to allow it to thicken up and feed a little each time it rains and they will stay lush..


Vegetables
Here on the coast Plant lettuce plants at two week intervals and any spare ground could be planted out in new potatoes, they are so much better dug just before you cook them.
My board beans are well up, I was once told to plant each bean with a little pot ash to help with rust problems, they still get a little rust but I think that's probably due to them getting too dry between watering's, like corn their roots are well up near the surface, mounding soil up over their roots stops roots becoming exposed and drying out too quickly.

Cheers, Linda.
