"Gardening in May"

This May has been perfect gardening weather.

Golden oregano (right); I plan to spread mine around the garden this autumn

In this year of crazy, mixed-up weather, May seems to be the new April. I used to think that April was the very best month of the gardening year - beautiful weather (mild, sunny and no humidity), lesser need for constant watering, and perfect for doing all of what I regard as the most enjoyable tasks, such as moving plants around to improve the borders, splitting up herbaceous perennials, and planting spring annuals.

This year, April was nothing like that. It was hot - really hot at times - and I didn't dare transplant, plant out new specimens, or anything else for that matter. In any case, I was too busy watering, because of the ongoing lack of rain. However, May - which I used to previously regard as one of the bleakest, unappealing months of the year - has come up trumps and has given us some of our most enjoyable days for a long time in Sydney.

Yes, the mornings and evenings have a chill, and we still have had no worthwhile rain, but the days in general (so far, and particularly the weekend we have just had) have been superb. Perfect blue skies and brilliant sunshine have highlighted the hues of the autumn-colouring trees that do well in Sydney (especially the plain Japanese maples, crepe myrtles and liquidambars, the latter best admired in someone else's garden) and which, despite the strange seasonal patterns, have still managed to put on a fab display this year.

I have finally been able to get into my borders and start ripping out plants I am fed up with, moving plants around that are in the wrong place, and planting out things that have been sitting in pots way too long. With the soil temperature still warm, this is an ideal time for planting, giving the plants time to settle in before winter. I have also now begun avoiding planting in spring, because it seems we get hot, dry weather much earlier than we used to, and newly planted things struggle to establish, in my experience. I've also begun dividing up herbaceous perennials that do well in Sydney, such as phlox and asters. They look like just mingy rosettes of moth-eaten leaves at the moment, but once spring arrives they will expand and flourish, and give a long period of flowers, a reminder of my cottage garden years, and blending in well with my semi-tropical stalwarts such as Salvia, Dahlia and Pentas.

Taking out plants has become more of a thing for me in recent times, as I now want bigger clumps of fewer types, to create a greater impact. Also, with too many plants crammed into a space, inevitably there are casualties that get smothered. I feel my trajectory is towards a simpler garden these days, repeating the plants that give colour over a long period with little effort required from me during the summer months when it is just way too hot to be in the garden. As I ripped out a few plants yesterday, I could almost hear the sighs of relief from nearby specimens that had been overshadowed by these pushy plants that had more negatives than positives going for them.

I also removed some shrubby perennials that had got too old and woody after a few years, such as Pentas and Artemisia. Cuttings were taken and they will be planted elsewhere once these have struck. We often forget that many of these plants have a limited life and are best renewed every few years. Another satisfying activity is digging up bits of robust clumping groundcovers and planting them to fill bare spots elsewhere in the garden - for example, golden oregano (pictured at the start of the blog) is going to be used more in my garden for its toughness and wondrously coloured leaves.

I have also been scattering seeds of spring annuals, such as poppies, wherever I see a gap. Maybe not many will germinate, but the few that do will bring a freshness and vitality to the garden in September and October, and hopefully may self-seed from year to year, as some already do, including nasturtiums, Orlaya, Nigella and Primula.

Enjoy these amazing May days - but we really could do with some decent rain!

I agree, May has been a good gardening time, and I have been trying to get my garden in order. My crepe myrtles this season, are colouring well. It is a timely reminder to keep a watchful eye on some perennial plants such as the pentas, cane begonias, etc. which do need to be replaced every three years or so. You do tend to think plants can go on forever and ever! The scattering of seeds is a great idea to fill in gaps. In my garden, I have poppies, nigella and primula regularly appearing. Glad to hear you have been enjoying the good gardening weather. Lovely to see those self-seedlings appear! Deirdre

Have you had success propagating your Tagetes Lemmonii? Wondering if they would grow from a woody cutting. I have grown the plant from cuttings quite successfully. Maybe try a variety of cuttings, from woody to tip cuttings. The softer ones would benefit from being in an enclosed environment so they don"t wilt too much. Deirdre

I Love to hear of people successfully scattering seeds - only wish it worked for me!! never seem to have any luck but will keep trying!! I know it ca be frustrating, I find it best when they self-seed: such fun to find them popping up. I pull a fair few out and just leave the ones that are in a good spot. Deirdre

Well I"m a lot further south & have had rain & May has been cold. Was lucky to get lots of planting out done in March & April. For me the race is on to get tidy for winter as there will be months when its too wet to weed/dig until spring. I agree its a good time for revising plantings & renewing salvias etc. Am really enjoying Euryops daisy now--a very common plant but I find its citrus yellow flowers very pretty with its blue green foliage & it will flower all through winter here.Such a very different climate; that is great that you have had rain. I like Euryops; mine is woody now and needs to be replaced. It flowers in winter here too. Deirdre
