In My Seed Box For 2026 - Sweetcorn

   

My daughter Kelly declared early on in my ownership of an allotment that all sweetcorn grown was hers. Historically we have had some great harvests and the two types of corn that I have grown between 2013 - 2019 have been Swift and Lark F1. 2017 was extremely disappointing but it would appear that most people in the UK had a bad year with their Sweetcorn. 

In 2019 Marshalls sent me two different varieties to trial which were Alliance F1 and Tyson F1 again due to the leg injury I didn't get the infrastructure in to trial both varieties in 2019. 

The results with Marshalls Alliance F1 Hybrid Sweetcorn were nothing more than spectacular (see photos of harvest here) and I have to say they were the best Sweetcorn that I have grown to date, Tyson F1 grown in 2021 were good but not as good as Alliance. 

In 2022 I attempted to grow Marshalls Moonshine F1 - 50 Seeds - £2.99 - packed year ending 03/21 and best before date 09/2022 The germination rate was less that 40% and what did finally grow got hit by the rats with fluffy tails that run along the top of the wall that's built on my plot boundary.

A second planting of Sweetcorn Picasso F1  - 35 Seeds - a New Variety to Mr Fothergill's in 2022 was tried, the germination rate was poor and then the rats with fluffy tails hit regardless of the pop bottles I had placed over the corns and I ended up with only 8 corns that were viable. this I though at the time was my worst year for sweetcorn ever, I didn't know what was coming. 

In 2023 I tried growing Sweet Corn Illusion F1 - 25 Seeds - a new variety from Dobies & Sweet Corn Eden F1 - Suttons Germination rates were down again, but once again the rats with fluffy tails just beat us to some of the sweetcorn, but my harvests were as good as in previous good years but not as good as 2019 which was an exceptional year.

In 2024 due to my cancer treatments and recovery growing sweetcorn didn't happen and in 2025 I tried growing Moonshine F1 , but these didn't start off well in the potting shed and failed and died and didn't even make it being transplanted into the ground. 

in 2026 I will be growing Sweet Corn Pot Of Gold F1 - Suttons - 20 Seeds - Cost £4.99 - Item Code 10 02 99 - that was Packed year ending 2023 and has a Sow By date of 2026. 

I'm thinking of trying A 21 hole planting sheet would be ideal if there is 100% germination, 18 hole works for a 90% germination rate. 

Planting Membrane for Sweetcorn 

I have 3 different planting membranes that can be used for sweet corn they are 18, 21 & 24 holes and look like this
