Does anyone have experience with having 18 gourds hanging on a 2" square aluminum pole. This would mean 3 levels with 6 gourds a piece. The catalog says it will support the weight, but they suggest adding a 2 ft. section to the pole which is currently 14 ft. I suppose that is for more ground clearance for the lowest section of gourds.

My concern is the added weight during severe storms which we are prone to in the spring, and whether the 2" pole would support the weight, these storms can deliver winds up to 60 mph.

Thanks;
Hanover Bill.

Howdy! I am also wondering the same about 18 gourds on a 2in pole. We are going to add on to our 6 existing gourds to make it 18 but are concerned about the 2in pole in high wind situations.

I’ve had 18 gourds on a 2 inch pole for years. Converted it to all ChirpyNest houses four years ago. Picture shows 20 ChirpyNest cavities. 12 singles and 2- 4 compartment houses. It’s been through many storms at full mast. However I do try to lower it about three feet if I know a storm is on its way. I feel more secure with the three inch pole but the two inch will handle the load.

My AAA is 2 inch and has 16 gourds on it. It is 10 plus year old and has just started to get a slight bend this year. I do try to lower it during forecasted storms but it's not uncommon in Indiana to have pop up storms where I can't get to it. I think adding more gourds would be a regional thing. Some places have higher winds and 16 gourds would be too much, some places might get away with 20 gourds.
2020 Currently 42 nest, 110 babies, 64 eggs left to hatch(6-22-20) HOSP count-8
2019- 31 Pair over 100 fledged
2018- 15 pair last count 49 fledged
2017 3 SY pair nested, 12 eggs total, fledged 10. 4 additional SY's stayed all summer but never paired/nested.

Hi, I have a deluxe 18 which is a 2"x 16 ft pole with lift off arms. That rack does much better in the wind than the round rack or AAA rack. One year I even had the extra weight of wire cage on it for owl protection, I was at work and a storm hit that bent two of my other poles over at a 30 degree angle. The rack was not damaged in the least. I think the main reason it does better than the other 2 inch racks is because the gourds are clustered closer to the pole than on the other racks in which the gourds are spread out at a greater distance from the pole.

Depending on nearby tree coverage and structure to block the high winds are something to take into consideration. I feel the increased weight and hieght are just a disaster waiting to happen. When in doubt always go verboard on beefing up the whole set up.
Mite control, heat venting, predator protection and additional feeding during bad weather add up to success.
