From my first time tinkering with rosemary back in 2008, I’ve definitely come a long way with growing herbs. Plenty of failure along the way and now over 4 years on since my last herbs planting post, I can tell you one thing. Both my basil and rosemary survived! BUT the rest of the herbs were not so lucky. The rosemary and basil are not the first generation because they’ve been propagated many times (especially basil).
As for the rest of the herbs like thyme, oregano, mint, dill, etc… I ain’t giving them up. Right now, I’m busy
playing experimenting on growing fruit and vegetable from seeds. This will be on another post.
My tips on growing basil & rosemary successfully in Malaysia
Note: The basil I have is called sweet basil
Basil and rosemary love full sun. You can plant them all year round in Malaysia and they will thrive. They grow really slow in sheltered or shaded area. I water them once a day in the morning or if I forget/lazy, evening will do too. If the soil is really dry, I might water twice a day but mostly once a day is enough as both basil and rosemary are hardy plants. If it has been raining, I don’t water them. I use organic soil or organic compost soil. And I dig the soil (to loosen them) every 1-2 months for better air and water circulation. I rarely fertilize my basil and rosemary plants and when I do, I use organic fertilizer.
Diseases on basil and rosemary:
So far, there is only one type of bug that attacks my basil (but not all the time). It’s a black bug, minuscule in size and they usually hang out in group on the leaf. Usually in this case (lightly attacked), I first try using water to wash them away. If they persist or when the leaf can’t be saved anymore, I’ll nip the leaf so that it doesn’t affect other leaves. I don’t use pesticide/insecticide.
As for my rosemary plants, they’ve been attacked by a type of white powdery infection and root rot when I placed them in shaded area. For the white powdery problem, I will remove the affected leaf. I don’t encounter both problems anymore once they’re out in sunny spot.
Harvesting basil and rosemary:
Plump leaves. Okay maybe not as plump as store-bought basil but that’s because I rarely use fertilizer. 😛
I normally harvest basil leaves in large quantity (to make pesto) when they are at their plumpest stage. How to know when they are at their plumpest? I guess by experience. Other time, I’ll just pinch a couple of leaves (near the top or mid section of the plant) for making salad, drink or pizza.
Flowers on basil.
I noticed that once the basil starts to flower for quite awhile, the leaves will start shrinking in size. I’m guessing the nutrients are being snatch up by the flowers. If you would like to harvest basil seeds (for future planting or making basil seeds drink), let the flowers mature. Or else, pinch the flowers off so that the leaves can continue grow larger. I usually identify the flowering stage as turning old stage. Because no matter how many times I pinches the flowers off, my basil leaves never grow larger like in its plumpest stage. So what I do is I start propagating and get rid of the old basil plant. Another method to prevent flowering is to give them a few cuts here and there. You can use the leaves from the cuttings for your cooking. This way, the basil plant can survive the longest without flowering.
A healthy rosemary will have its leaf perks up. Yeah mine not that good-looking but hey at least they’ve live for over 4 years. 🙂
For rosemary, they can be harvested anytime. I usually choose young stalks (at the top) for cooking and avoid thick hardy stalks. I guess the young stems are more aromatic. My rosemary plants never flower so no comment. Although they never flower, they grow into a big large bush. You can trim them from time to time. I had two rosemary plants in two large pots previously but I have uprooted one to plant a new rosemary plant (also by propagating).
Propagating basil and rosemary:
I propagate both basil and rosemary via cutting method. It’s a very easy method but I don’t always achieve 100% grow rate but I have more success in propagating basil than rosemary. In one year, I usually propagate basil by cuttings between 30-40 times. That’s because I have 5 pots of basil (hehehe); three in sunny spot and two in the shade. The ones at shaded area act as my guarantor. 😉 But why do I need so many pots? Because one pot is not enough to make pesto and the growing rate is different for each plant. Ohh btw, each pot contains about 4-5 basil plants.
As for rosemary, I’ve only propagated about twice or thrice in the past four years. That’s because rosemary is a perennial herbs. They live very long. Actually so is basil but as I mentioned above, once basil starts to flower I will uproot them.
Once you cut the stalks of basil or rosemary, you can put them in the water and let them start rooting. I always skip this method (=lazy of waiting). I plant them straight in the soil. 🙂
Here are my methods for propagating basil and rosemary:
Choose a young basil or rosemary stalk for cutting.
Although it says cutting, I don’t cut it with scissors. Just nip it simply with your fingers will do. They’re soft. 😉 Remove leaves from the lower stem.
Plant the stalk into the soil and pad on the soil around it so they are not loose.
Now, all you have to do is wait for nature to take its course. At first they may look limpy and lifeless. Rosemary cutting will take quite a while to get accustom to the new surrounding. It will be months before you start seeing real progress. As for basil, they also need time, but usually within 1-2 weeks, you will see progress.
Not sure if you know that basil is called selasih in Malay. When I found out it’s selasih, I went ah-ha! I’ve heard, seen and even drank biji selasih (basil seed) drink before. My favorite air bandung has biji selasih in it. To make basil seeds drink, the basil seeds need to be soaked in water and after a couple of minutes, you’ll see that it has developed a translucent outer skin just like chia seed. Add them to your drink then.
