Gooseberry Sawfly and bolting onions

If you have gooseberries, now is a jolly good time to see if the leaves are vanishing.

If they are, the chances are high that they're being eaten by gooseberry sawfly.  They chomp their way along the edge of the leaves and are quite hard to spot until you get your eye in. Tiny green caterpillars.

If you don't want to use chemicals, pick the little blighters off by hand.  Richard's just picked 500 (no, that isn't a typo) off the bush in his back garden. 

Once, when he was a lad, his mother offered him 1penny for every caterpillar he picked off her bushes.  She only ever made the offer once...

If you have onions or other plants that are bolting (flowering and setting seed when they should not be) , then the cause is almost certainly lack of water.  We've been watering our onions regularly (and giving them the dilute urine treatment) and they're looking a lot larger than last year's ones already.  Although, to be fair, I'm talking about autumn-planted onion sets, which have a head start.  The spring planted sets are still small in comparison.  They're growing well though, healthy green leaves and the stems are starting to thicken up, but only a few are starting to swell into bulbs yet.  Keep weeding as well.  You want your plants to get the nutrients, light and water, not the weeds.

No gooseberry infestations here *touch wood*, but one old bush is dying off, clinging on a little and has produced a few fruits. Its companion died a few years back, and one old blackcurrant bush in the same area has almost gone too. Do fruit bushes die of old age, or could it be something sinister? I suspect ants that farmed aphids on the blackcurrants, as I mentioned a couple of years ago.

No onions here, but my spring-planted garlic seems to be doing well, I've been watering and occasionally feeding them. The chives are in flower and they look (and taste) great. I might be adventurous and try onions next year.

Have you been pruning them properly? Blackcurrant and gooseberries have different pruning requirements.

If you don't cut them back correctly, then you won't have wood of the best age to bear fruit.

Aw, weeds...I do my best, really. This year I have got a new cathegory of a weed - it is a plant - actually a flower!that had spread its tiny seeds around. I haven´t noticed until now when the whole flowerbed is covered with numerous young garden bells. It is nor easy to weed them. Now I managed to clean them but lots of them opened their bells and I haven´t the heart to destroy them. However I will not allow them to stay and produce the seeds again!

I don't dispute they're a pest and need to be controlled ... but the adults are rather pretty.

Yes, I've pruned the blackcurrants over the years, and it's always been a good fruiter. The gooseberry bush hasn't been large enough to prune really, but my Dad split it about ten years ago, and the split-off bush has done well. I'm not too worried, and tbh I think it's time to wave them both goodbye.

Have you been giving it any compost/manure? If you starve it, it won't grow...

Another 112 Gooseberry sawfly caterpillars found tonight.
