How to prune:
Pinch back and then out the tops of your new shoots. The best time to pinch these shoots is when the new growth on leaves begin to solidify. Sub-branches should be pruned June and in July. You want shorter branches. In September, you want to reverse the role and allow the branches length.
You can prune the main branches at the bloom of flowers, or as the fruits take its shape.
How to wire:
Wiring is essential for shaping bonsai. In spring and fall, you want to use straw-colored ribbons, which you can obtain from the leaves on raffia palms. The fiber makes a great wrap, which you will need to twist around the wire to protect your plant. Start wiring when hardening shoots appear.
How to water:
Plenty of water will keep your Crataegus Ornamental Thorns happy. When the plant starts to flower however, reduce water intake.
How to spray:
The foliage only should be well sprayed during dry seasons, or warm conditions.
How to feed:
Spring and fall, after the spurt of growth ends you want to reduce feeding. Use liquid feeding in fall and add a bit of phosphate and potash when the fruits start to develop.
