When is the best time to prune jasmine
Today, the editor will explain to you when to prune jasmine and how long it takes for the plant to germinate, as well as knowledge about green plants and flowers. The specific content is as follows:
The timing of pruning jasmine directly affects the plant's growth, flowering quality, and subsequent germination speed. Mastering scientific pruning methods can promote the germination of new branches, extend the flowering period, and shape a beautiful plant form. Here is a practical guide on pruning and germination of jasmine:
- - One, choosing the best pruning time - - 1. - -Spring shaping pruning (February-March) - - - Complete before germination, choosing sunny days with a stable daily temperature above 10℃ - Cut off dead branches, weak and diseased branches, and crossing branches, retaining the main sturdy branches - Shorten old branches by 1/3 to stimulate new buds, paying attention to retain 2-3 full bud points 2. - -Light pruning after flowering (May-September) - - - Prune immediately after each batch of flowers fades, avoiding rainy days to prevent fungal infections - Cut off the remaining flowers and 2-3 pairs of leaves below them - Thin out dense branches to improve ventilation, retaining outer bud points to promote horizontal growth 3. - -Autumn shaping pruning (before mid-October) - - - After flowering stops, cut off the suckering branches and inner branches - Shorten the current year's branches by 1/4 to balance nutrients - In the southern regions, it can be extended to early November Taboo period: Pruning during the winter dormant period can easily cause frostbite, and pruning during consecutive overcast and rainy days can make it difficult for the wounds to heal.
- - Two, the law of germination time after pruning - - 1. - -Temperature determines germination speed - - - 25-30℃ environment: visible bud points will swell 7-10 days after pruning - 15-20℃ environment: it takes 15-20 days to germinate - Below 10℃ may stop growing 2. - -Variety difference comparison - - | Variety | Germination Speed | Characteristics | |-------------|------------------|-----------------------| | Tiger Head Jasmine | Slower | Single-petal varieties germinate faster than double-petal varieties | | Ba珠 Jasmine | Moderate | Thicker branches take longer to germinate | | Pen Tip Jasmine | Fastest | New branches germinate faster | 3. - -Maintenance conditions affect - - - Light: More than 6 hours of scattered light per day can speed up by 30% - Humidity: Germination is 5 days earlier in a humid environment than in a dry one - Nutrition: Applying diluted fish protein fertilizer after pruning can speed up germination by 3-5 days - - Three, 4 core technologies to promote germination - - 1. - -45° oblique cutting method - - - Cut obliquely 1 cm above the bud point to minimize the incision area - After pruning, apply plant ash or carbendazim to prevent fungal infections 2. - -Bud promotion technology - - - Use a blade to make a light horizontal cut 2 mm above the bud point on sturdy branches - Break the apical dominance and promote the germination of lateral buds 3. - -Water and fertilizer协同 management - - - Water thoroughly with a potassium dihydrogen phosphate solution (1:1000) on the third day after pruning - Spray 0.1% urea solution on the leaves weekly 4. - -Light control - - - Move to a full-sun environment after spring pruning - Avoid strong sunlight at noon after summer pruning - - Four, special case handling solutions - - 1. - -No germination after pruning - - - Check if the cut is black: Re-prune to a healthy part - Supplement chelated iron solution to prevent deficiency symptoms - Wrap with plastic wrap to keep moisture and promote bud growth 2. - -Old stump renewal and rejuvenation - - - Strongly prune plants over 3 years old to 15 cm from the ground - Combine with root pruning and replace the soil - The germination period extends to 30-45 days 3. - -Black and rotting bud points - - - Immediately cut off the affected part - Spray with a 800-fold liquid of mancozeb - Change to bottom irrigation method - - Five, pruning tool selection and maintenance - - 1. Preferably use spring shears (for branches with a diameter <1cm) 2. Disinfect with 75% alcohol before and after each use 3. Sharpen the cutting edge after pruning every 5 plants By accurately grasping the pruning timing and cooperating with scientific maintenance measures, jasmine can enter the rapid germination period 12-18 days after pruning on average. Practice shows that correctly pruned plants have a 40% increase in flowering volume and a 25% increase in new branch length compared to unpruned同龄 plants. It is recommended to establish a pruning log to record the germination response time after each operation, gradually mastering the rhythm of personalized management.
