Gardening update

Just a wee one today, little bit ranty.
The garlic I planted is doing well and growing fast.


My broad beans and experimental out-of-season peas have all sprouted beautifully.



 




But, but, but... so have the sour sobs. AARGH!


The problem with sour sobs, my most-disliked garden weed, is that they make a thick, suffocating carpet, swamping any other poor green things that happen to be trying to eke out a living in the vicinity.


These beastlies have gone mad in MIL's vegetable patch, and now they have turned up en masse in my 'new' garden beds, the ones that were previously lawn. Now, having been lawn last year, I don't remember there being so many. I guess the grass kept them down. But now, freed from their constraints, the bulbs that have clearly been lurking in the soil have gone, 'whoopee! Let's make a run for it! Our time is here!'
One of the other problems with sour sobs is that they are almost impossible to get rid of, propagating by little bulbs in the soil that hardly ever come up when you pull the plant, no matter how careful you are. Apparently, if you pull and pull and pull the plants, over some half  dozen years you will deplete the bulbs' energy reserves sufficiently and get rid of them that way. You can also poison them - best done when the plant is flowering - but I see this as a last resort only to be employed when in dire straights.
What is the solution? I cannot let them run riot in my garden; I will never be rid of them. So I am trying something out in both my and MIL's garden. I am sort-of 'hoeing' them down, scraping them from the soil and hacking them into the ground whenever they appear. I will let you know how this goes. I wonder how many times I'll have to do it over the season?

Weeding

On Sunday I finally got around to pulling out some of the weeds that were colonising the front lawn and rose garden. I got two buckets worth out of the lawn alone. Thanks to all the rain, the ground was very soft and they came out beautifully. Rather worrying was the number of soursobs I pulled out. This little South African number (Oxalis pes-caprae), introduced into Australia as a garden plant, is a serious space/light competitor and even though I'm told they aren't taken very seriously, as they aren't around the entire year, they are the bane of my gardening life. And this is why: This little bugger had a root over 60cm long! It was out of the rose garden and the roots were under the mulch, not the soil, which is why it came out intact.


All along the roots grow little bulbils and it is those thingums that are the real problem. Soursobs spread by bulbs, and lots of them, in fact a lot of the time they don't set seed at all. The bulbs are quite obvious in the photo below. It's a long, long process to get rid of them. As I prefer not to spray poisons in my garden, I'll be pulling these suckers out for years to come. I'm hoping the key will be to never let them get out of hand in the first place. So, one bucket of weeds for the compost, and all the soursobs to go into the green waste bin, along with their bulbs!



I finally got out the back as well and stated to clear swathes of weeds. Quite embarrasing, some of them had become quite enormous. Wish I'd taken a photo of some of them with something for scale, but all I have is a photo of three piles of weeds which don't look nearly as impressive her as in real life. I think I'm going to leave them just where they are so they can moulder and break down into compost and get dug into the soil later.


Weeding is quite therapeutic sometimes. There is something very satisfying about pulling out all those plants you'd rather not be there, especially when you have a personal vendetta against some of them. I have to say, however, that all the thistles and grasses made be wish we had a rabbit to eat them. I have fond memories of collecting thistles for our rabbits and guinea pigs when I was a child, of letting some of them get big just so the critters could have a treat.
