How can I get my Manchurian Pear to flower

The buds came again this autumn, before it drops its leaves. Season confusion? It looks healthy, is well watered, situated in a lawn. The lawn was replaced over the summer with a more shade tolerant variety. While in progress I gave the tree Seasol out to the drip line and it would have benefited from the soil improvement, preparation and fertilising for the lawn. We live in an elevated area in Perth metro. Typical Perth sandy soil. Is there anything we can do over winter to get it to flower in spring? Pluck the buds off? Prune a foot off all over, where the buds seem to be (note the height)? This is our second winter in this house (and garden). thanks!

Hi LJ,

It would probably be best not to prune the Manchurian pear as you may find it produces quite a lot of vertical shoots. The buds that have been produced may not open until Spring if the weather cools down quickly for Winter. It would appear that Perth has had very unseasonal weather for the last 2 years and the tree may be experiencing some 'climatic confusion'. Do you have many possums in your area? They love to eat blossoms and flower buds such as ornamental pears and magnolias. Yates has a wonderful new product available - Yates Possum Repellent Spray helps protect your precious plants by deterring possums from browsing on sprayed plants.
Contains a special combination of ingredients that help reduce possums browsing on plants.
Lasts for up to 7 days or more with regular re-treatment.
Can be used on ornamental and edible plants and has only a 1 day withholding period.
The formulation was developed by Professor Lynne Selwood and is protected by a patent granted to the University of Melbourne.
Did the tree flower at all last year or did the buds drop off? Be careful if you are applying fertiliser or herbicides on the lawn surrounding the tree. High nitrogen will produce leaf growth and may restrict flowering. Fertiliser such as sulphate of potash which contains potassium will help promote flowering.
