Apple Trees - Espalier Trained- Potted

We have Espaliers which are ready now as well as some which you can reserve, these being ready for Late Spring / Summer 2023 for  planting but this is dependent on the weather.  The Espaliers are potted so once they are ready, they are fine to be planted. Our  1 tier espaliers have 1 tier  (a horizontal branch each side) with a main leader so subsequent tiers can be grown on & trained.
