We’re getting close to the time when growers need to make chemical thinning decisions – for many the most perplexing and risky decision they will make all year. This is usually a tricky call to make. Remember that only about 5-10% fruit set is usually enough for a full crop. In other words, 90 out…Read more about Chemical thinning[Read More]

Once flowers open in the spring, we’re hoping for warmer weather so the bees will transfer pollen and for rapid pollen tube growth. As we all know, apples require cross pollination, so for example Golden Delicious pollen will not fertilize Golden Delicious flowers. We rely on bees and other insects to transfer pollen from one…Read more about Pollination – a refresher[Read More]
Something happened when the calendar switched from March to April. Spring finally sprung. As we discussed in the last issue of FFF, spring temperatures are so important because the rate of crop development in the spring is directly related to how warm it is. Here in Lafayette, April average temperatures have been in the 50s…Read more about Spring temperatures[Read More]
It seems like the last couple of months have been unseasonably warm, but when we look at the data, it’s not so clear cut. It’s true that in Lafayette we’ve had days with highs of 65 and 70 in late February and early March, but also a lot of low daily temperatures closer to 40….Read more about Spring temperatures[Read More]

During our wrap up meeting at this years Hort Conference, there were many views and ideas shared with the group. The general consensus was that this organization does…Read more about Attention Indiana Horticulture Society Members, notice from the President, Matt Chandler[Read More]
With apples over an inch in size, we traditionally consider that the window for hand thinning has closed. At this point, it’s unlikely we’ll see a thinning response either in terms of fruit size or in flower initiation for next year. But there’s still a good reason to consider some hand thinning. Many in the…Read more about Apple hand thinning[Read More]
