1. How to grow rosemary from a cutting
Gather your supplies
• Seed-raising mix
• Mini propagator with cell growing tray
• Rooting hormone
• Multicrop plant starter
• Watering can
• Spray bottle
Step 1: Fill tray with seed-raising mix. Snip 15cm cuttings from top of plant and strip leaves from bottom.
Step 2: Dip cuttings into a rooting hormone then place dipped end into seed-raising mix. Press each cutting firmly into mix with your fingers.
Step 3: Dilute Plant Starter, following instructions, and apply to cuttings. Cover with lid and put in a warm spot with indirect sunlight. Fill a spray bottle with water and mist cuttings daily so soil doesn’t dry out.
Step 4: In 2-3 weeks, test for root growth by gently tugging on cuttings. Once roots have formed, relocate into individual pots or into ground. Pinch off top of cuttings to encourage branching.
2. How to grow rosemary in honey
Interestingly, rosemary cuttings can be propagated using honey.
The process is the same as above, except instead of using a synthetic rooting hormone, you can use honey to promote root growth.
3. How to grow rosemary in water
With suitable cuttings, rosemary can be rooted in water. Make sure when selecting the cuttings that you choose new fresh green shoots and not the stiff woody stems. Strip the leaves about 5 cm from the base, and submerge the ends in water. Make sure no leaves are in the water; they might rot. Now all you have to do is wait. It can take 3-4 weeks before you see any root growth.
