We recently started carrying a grown and made in Alberta fertilizer called Ovis Aries made by an entrepreneurial friend of ours. So I could be biased since this year was the year we decided to get a bottle baby lamb but I'm thrilled with this new fertilizer I've been using for several reasons. I have tried it in our greenhouse and in some of my pots and in as I was putting it in with one of my flower beds to test it out in a variety of scenarios. I didn't get too scientific but I put about a tablespoon in every hole for the greenhouse tomatoes. I also added a bit of bone meal to round out the macronutrients. In the same greenhouse on the same day I did my standard slow release fertilizer with the same variety of tomatoes in a bed right across the aisle.
At this point I can't tell a difference in terms of size of the plants, but where I'm noticing a difference is how they're managing with this recent heat wave (and what looks to be another one coming up). One of the additional benefits of this fertilizer is that it can retain moisture and release it back into the soil. You can imagine in a greenhouse how things can heat up but one of my indicators to water has been the beds with the slow release fertilizer. If I only looked at the beds with the Ovis Aries fertilizer, I could probably go another day or two. I'm interested to see if it influences fruit set or even taste of the tomatoes.
In the pots I've been really impressed with how they've held up in this heat as well. Hanging pots are notorious for drying out and ours get the benefit of the drying westerly winds. However, I mixed in several tablespoons in when potting them up and they are the best I've ever been able to grow in this location (so far). The other hanging baskets (which the plants came from the same nursery) did not faire so well with this last round of heat and I'm not trying to remediate them for hopefully some blooms by August.
The fertilizer supposedly has benefits with slug control too, but that is yet to be seen - one can only hope that we have enough rain to test it out. I would like to try it out in my row crops but that will have to wait for next spring. Either way this is a definite must for all potted arrangements and the greenhouse crops from now on at this farm.
