Pest Problems

Did you know that yellowing leaves on a bean plant could be caused by more than half a dozen different things? It's true, and none of them are easily identifiable, either. My garden is plagued by pests and I really just don't know what to do about it.




When I was originally reading about the things I wanted to plant there was always information about the sort of pests I was likely to encounter. White cabbage moth, slugs and snail, leaf-eating beetles... I put them out of my mind, figuring any critters in my yard would be easy enough to spot and therefore deal with. I also read that some plants want more or less of certain nutrients in the soil but short of buying kits to test the acidity levels I really couldn't do a lot about that. So, merrily, I planted everything my little heart desired and away I went.

Some things have been fine - I haven't noticed anything amiss with the tomatoes, basil or strawberries. The spinach and bok choy grew better and faster than I could keep up with (even in the summer - I can only imagine how well the bok choy would do in cooler weather if it grew this well in the heat) and the raspberries I brutally cut back have already sprouted a second batch of flowers. The problem I'm facing at the moment is that not all of my plants are thriving as well.


The cucumbers - while massed with flowers and stubby little gherkins - have holey leaves and chewed-looking stems. Some googled culprits for the stem damage are 'squash vine borers' but the holes in the leaves don't look ragged in the same way - mine are large, round holes with smooth edges, similar to what I've seen on the beans and tomatoes too.

You can see on the left one of the chewed up leaves.

I have seen snails in the yard after rain and am planning to get a bucket of ash from my family (they have a wood combustion heater) as I've heard this can be used to keep slugs and snails out of garden beds, although I haven't caught any of the above actually on the plants. The problem is that I've only seen three living things hanging out on my plants.


This particularly non-camera-shy little grasshopper has only been spotted once and at the time seemed a fairly innocuous visitor. A quick search online tells me, however, that they actually can do a lot of damage to gardens. Perhaps some of my problems are from guys like this one?


This pretty little thing was a welcome guest, given the third of my visitors you are about to meet. I only wish I had more of them around!


I have to admit that once I harvested my corn I sort of ignored the stalks for a while. I'd heard you should compost them right away but hadn't given it a second thought - until I noticed that the tassels were covered in something black. And when I looked closer the entire plant was covered with an army of ants and a host of nasty black aphids. Like... a horrific number of them! I chopped the stalks up ASAP and got them away from my still-growing plants and haven't seen any since but I wouldn't be surprised if they're around and I just haven't noticed them... I'm keeping an eye out, though!

The internet suggests that birds can be a great help in bug-handling but at the same time those same birds are going to be interested in my plants themselves. I have strung up some shiny old cds around the beds to keep the local blackbird population out after I caught them scratching up my freshly-planted seeds and haven't seemed to have a problem since (they still visit the yard sometimes but usually sit at a distance to the beds). I would love to have bird feeders and encourage them to come around, but I also don't want them reaping the rewards of my garden! Would bird netting be difficult to work around?

Currently my pest-deterrent plan has really just involved my daily visits to the garden to ooh and ahh over the growth (I swear it changes every day!) and a quick peek around the plants (and under the leaves) to see if I can spot any troublemakers at work. I haven't found anything yet but clearly somebody is at work in here so the vigil will continue!
