The following are some notes to help you and your staff get the best from the plants received. If you require any further advice on plant care or any matters regarding this or other deliveries from Yorkshire Plants please call 01845 501494.
Both Gages and Plums are prone to Bacterial Canker which is encouraged by container growing. We recommend you take delivery of your trees in July and August and sell through by October. This will give the trees a chance to make some roots into garden soil before winter. This will give trees the best chance of growing away healthily. Any trees not sold during this time should be stored in cool, dry and light conditions from the end of October until leaf break in April. Do not water during this period. An open canopy that keeps the plants dry is ideal. Mild wet winters promote Bacterial Canker. Plants taken in spring should be thoroughly inspected at delivery and any complaints should be made within 7 days of delivery. Full credits will be given if plants are showing signs of the problem. After 7 days responsibility lies with the purchaser.
Young plants in containers are susceptible to foliage damage from frosts during April, May and June. A – 4 oC frost in April or May will severely damage young leaf growth on deciduous plants. If the frost comes when plants are most vulnerable it can kill them. Cercidipylum, Cornus, Fagus Hamamelis, Magnolia, Parottia, Prunus, Quercus, Salix, Syringa and Wisteria have all been damaged in recent years due to spring frosts. Take precautions, cover plants with a thick grade fleece at night when hard frosts are forecast. Some plants will be best displayed in open canopies that give some frost protection. If your plant area is low lying and gets early morning sun then you will need to be especially careful during the spring where you place your plants.
Encourage your staff who water plants to check the moisture content of compost. This can only properly be done by knocking out the plant from the pot. If the compost is saturated with water (all air space filled with water) then you will need to take action. If it is from rain and more rain is forecast move the plants under cover. If it is from too frequent watering extend the period of time between watering and or reduce the amount of water given.
All plants can suffer from water logging of compost, some of the most vulnerable are Catalpa, Cornus, Cytisus, Hamamelis, Laburnum, Magnolia and Robinia.
These are broad recommendations, call the above number if further assistance is required.
