We’ve struggled with spider mites in the past. Nasty pests. But this was a new one for me. False spider mites. We started to see damage on our mint at the end of March. Necrotic (dead) areas along the margins of the leaves and sometimes a whole leaf. This looked similar to some spider […]
When I was walking my tomato crop, I noticed significant signs of phosphorus deficiency. (Purple on the old leaves). A quick check of the
We’ve been struggling to get our basil bed to grow properly. We have done water tests and tried to adjust nutrient and pH levels in our beds. But I think we’ve finally figured out why we keep getting chlorosis (yellowing in the leaves). Pythium.
The tomatoes are now in full bloom. They are a little more vegetative than I would like–and a bit stretched–but the flower clusters look healthy and I am happy with the pollination to this point.
From disease and insect control to plant growth and generative vs. vegetative signals, there are many issues closely tied to controlling your growing environment’s climate. In my region, winter is the most difficult season
Over the last week we began to see a dramatic increase in aphid populations in our greenhouse, especially in the lettuce.
This week we introduced quite a few biological control insects (for prevention). * hypoaspis – these are mites that live in the soil or other media that we grow plants in. We use them primarily to control thrips
This last week was very busy for our Integrated Pest Management (IPM) program. My sister (and greenhouse business partner) built a home for grass aphids on Thursday. It always feels a bit strange to protect the aphids, but we use them as food for keeping colemani wasps in the greenhouse. This is a lot cheaper […]
After treating the infested violas two weeks ago, the violas are doing much better overall.
My tomatoes were looking great last week. They were at the 6-7 leaf stage about 25 cm tall, and a perfect dark green throughout the plant. Notice that the area outlined here is the same colour as the area outside the circle. It’s common, in my experience, that you will see symptoms of underfeeding here […]
