A board such as a 1 X 3" is simply to keep rain from dislodging the tiny seed from the soil and retain moisture. I check my seed germination after a week then daily until the seedlings are about 1". Then I remove the board, thin the seedlings and cover with a floating row cover. I plant them right next onions and have no problem with flies.

You only cover with a board temporarily as to keep the seeds from washing away and from birds eating them. After a week or more, You are to begin checking for sprouts. Within a week to 10 days, if it’s getting hotter in your climate, you elevate the board above the sprouts by placing a rock at each end of the board length and place the board on top of the two rocks. This keeps it a bit shaded since carrots are cool weather. Then as they get larger ferns and safer to expose, you remove the board. I hope that’s helpful.

Thank you. Your explanation was clear and much appreciated.

Use shade cloth or hessian bags above the soil.

Can I find tropical carrots varieties seeds that suitable to grow here in Malaysia?

Any common carrot should. It is more about when to plant and soil type.

I have had carrots with for legs and then two by thinning consistently. The last one was single at the top but had multiple small legs at the bottom. How do I stop this?

Best to grow carrots in a sandy loam kind of soil. Don't need a lot of nitrogen. Also I wouldn't thin out too much. I don't grow them because they are cheap to buy and take so long to grow.

If you want to reduce forking of the roots - you must stop digging and tilling and hoeing. No dig beds are your answer and only do compost as your medium to grow. They are light and airy and nutrient dense.

I thought I might mention: after you harvest your first crop of carrots you probably have enough time to grow a crop of the smaller varieties of radish. Radishes: ******** Germination temperatures: ideal 15c - 25c acceptable 10c - 30c ************ Germination time: 5 -10 days *************** Growing temperatures: ideal 10c -18c intermediate to short day lengths -Growth must be continuous and rapid for good quality. Acceptable grow temps 4c – 24c. Roots of globe varieties tend to elongate and develop poor shape in hot weather when the tops also grow taller and larger than in cool weather. Long days induce flowering or seed stalks (bolting) and with warm weather the seed stalk may develop so rapidly that no edible root is formed *************** Days to harvest: Regular radish reach market size in 21 to 28 days. Chinese radish take 50 to 90 days (or more) to mature. ** A regular radish seed can produce a radish from planting to harvest in about 33 days. This crop also likes short day lengths and cooler temps making it an ideal crop to “squeeze” in late in the season, before the first frost. With a first potential frost date of October 15 – you could direct sow radish seeds like Cherry Belle, or French Breakfast (both with about 21 days to harvest from seedlings) on September 7th and reasonably expect to harvest your radishes before the first frost. You could also sow in trays and then plant them out… if real-estate is an issue, or if you need to get the radishes started before your harvest your carrots (timing) ************* Storage and Conditioning the recommended storage temperature is 0 C with a relative humidity of 95% to 100%. Topped radishes packaged in perforated plastic bags will keep for 3 to 4 weeks. Bunched radishes will keep 1 to 2 weeks. ********** Temperature information was gleaned from: ATLANTIC PROVINCES AGRICULTURE SERVICES and amalgamated with information from individual radish varieties such as Cherry Belle. ****** if you don't harvest your radishes on time they will be pithy/mealy
