Here you can see a more considerable covering of powdery mildew on the Lathyrus odoratus plants. Though, looking on the bright side, these Lathyrus odoratus tendrils have formed a beautiful heart shape. Pictured during my 2016 Sweet Pea Trial.
I have always achieved excellent results, growing my sweet peas in peat free compost. For my 2016 Sweet Pea Trial I used Dalefoot Potting Compost, a peat free compost made from natural ingredients, including sheep's wool.
I grow my sweet peas in Deep Rootrainers - deep seed trays, which feature ridged cells, designed to encourage the formation of strong, healthy roots. Each section of a Rootrainers tray is removable. The sections unfold and open out like a book, allowing easy examination of the plants' root system as it develops, and ensuring the straightforward removal of your seedlings when it comes to planting.
I grow my sweet peas in Deep Rootrainers - deep seed trays, which encourage the formation of strong, healthy roots. I use the Rootrainers Racking Station, which is a great space saver - it holds eight packs of Deep Rootrainers over two levels.
This photograph was taken on the 18th June 2016. Here you can see that powdery mildew has begun to establish itself on the Lathyrus odoratus plants. This is Lathyrus odoratus 'Ida King' which has been grown as a cordon, this was the first plant to become susceptible to powdery mildew in the 2016 Sweet Pea trial.
Bud drop is a commonly experienced condition on Sweet Pea plants. The Sweet Pea flower buds turn a pale yellow-green, as you can see in this picture, and drop off before opening. Once you have encountered bud drop, it's easy to recognise the early signs of the condition. I remove any of the affected flower stems as soon as I notice them.
