Problems (and Pests) in Paradise

I've been meaning to get to my garden since it rained on Tuesday, and it's now Saturday and I finally made it (for a little while, James was with me and had to rush back home to get ready for his soccer jamboree--I'll need to return this afternoon).  What greeted me was joy at seeing my lovely garden after a busy week, and then feeling my heart fall as I realised that this beautiful plot is no longer immune to gardening problems and its level of perfection has definitely plummeted.

I knew that this had started:



But didn't know that it had spread so much.  Actually, I was hoping that it hadn't spread so much. It's powdery mildew, and is caused by overly wet conditions (what?!) or high humidity.  It has been humid here this summer but nowhere near as humid as usual, and it certainly hasn't been wet.  So a little surprised and not so happy to find this little problem in my garden.  It especially affects squash plants, and none of my zucchini, pumpkin, and two precious butternut squash plants escaped unscathed.  So I pulled off the most affected leaves.  I left some of the others because I didn't want to take away all of the plants' photosynthetic ability, but I am worried it will spread.  I put the diseased leaves that I removed into a plastic bag and brought them home to our waste bin.  I pulled off extra leaves around the base of the plant where they were pretty bushy to increase air circulation, and I tried one organic-gardening-friendly home remedy:  I sprayed them with a 50% water 50% milk solution.  I used this solution on both affected and unaffected leaves, and I think I'll have to do it every few days, but I am hoping it will help.  I have also heard that a baking soda solution is helpful too--and if I need to do that, I will as well.  I'm only watering the base of the plants, and only early in the day so they have time to dry.  If you have other suggestions regarding powdery mildew and how I can fight it without using anything toxic in the garden, I'd be very grateful.

My ever ready and willing garden helper sprays the leaves too.

So now those leaves that aren't turning grey have white drips all over them. :)
Next on the list of troubles:  Colorado potato beetles.

I knew it was only a matter of time before they found my eggplants, but I thought that I would discover them as adults and get rid of them before they could reproduce in my precious patch of veggies.  Unfortunately, that was not the case:

Yuck.

Get off there, you!
I found them in voraciously-feeding-squishy-gross larval stage.  I didn't notice any egg masses, so I would be thrilled if the ones I found were the extent of it, but I'm sure that would be dreaming.  I picked off every little goober that I found and threw it (provided I didn't accidentally squish it) into the same plastic bag as the mildew-y pumpkin and squash leaves.  Next time I'll bring a mason jar with soapy water in it to collect them, I wasn't expecting to encounter these dastardly little leaf-chomping demons today.  Thank goodness for gardening gloves, is all I can say.  Yes, I'm a biologist, and yes (Johanna!) I am a little squeamish about bugs.  Not all bugs, just certain ones, but I still don't like touching most of them with bare skin.  It's my first year vegetable gardening, so I imagine I'll get over it.  Not yet, though.  Of additional concern are the following:

  • I naively planted my peppers, eggplant and tomatoes all together.  Well, there is a little buffer between the eggplant and tomatoes in the form of cucumbers and a couple of barely producing peas. But I found a little guy in the cucumbers and I am sure they will discover the tomatoes later on.  I really hope that they don't take to them, my prized crop!
  • The guys sharing the plot next to mine have a LOT of potatoes planted.  I saw the horrid little creatures in there too, and plan to email them to warn them about it.  I really don't want them to decide to relocate to my plot!
I know that Colorado potato beetles have a strong preference for eggplant, so I am hoping that at worst the vast majority of them will be drawn to those plants and I will have to fight the good fight in that part of the garden.  Even if I lose, if it keeps them away from the tomatoes, which I am just crossing my fingers hoping they don't enjoy nearly as much, it will be worth it.  I've mentioned before that I have only eaten eggplant once, so as disappointed as I would be, I think I could handle it.

In other, more exciting and happy news, James and I discovered this little friend rapidly crawling around in the pepper plants:

Welcome!
It's a lady bug larva.  And although it would be rare to hear me refer to any insect larval form as cute, I think this little dude is seriously cute.  Especially when I saw how fast he/she/it could go.  Not only do they turn into pretty ladybugs, which are a favourite of all small children and most people in general and are considered good luck by many, but it will eat aphids.  Lots of aphids.  AND, I discovered today upon my return from the garden, they eat Colorado potato beetle egg masses.  Wahoo!  So I hope that this little friend has a big clan just hiding out in the leaves ready to bring destruction on the pest population of my garden.  But even just one is pretty nice to find. :)
