I have a 30 cm tall Cherry Tomato in a 20cm plastic pot. Do you thing it is time to transplant it to it's final pit of 14 inch pot? Attached photo.
Can't see any attached pictures... I transplant my tomatoes when they are 4 to 5 inch tall. So obviously, yours are going to survive even better! See attached picture of my cherry tomatoes below.
Then it must be the internet connection or something... Anyway I have seen people transplant tomatoes as small as 3 inches, without anything bad happening. So nothing to worry about in my opinion. As Long as the delicate roots don't get damaged - Absolutely nothing will go wrong. Only reason why I transplant my tomatoes at 4 to 5 inches height is - I am too lazy sometimes... So I decide to transplant them when they are 3 inches tall. But actually get around to doing it when they are 5 inches. Basically, you can transplant your tomato plants the moment they drop their seed leaves. Or when other leaves become 5 to 6 times larger than the seed leaves.
In my opinion this doesn't require any transplanting into any new place. The container is already enough for one plant. Therefore no action is required on your part. Aside from watering.
Outgoing, I always give potted tomatoes as big a pot as I can. I would move it to the 14" if not bigger.
Do you have a 5 gal. bucket? If you poke a few holes on the sides about 1" from the bottom and fill it with good soil, your cherry tomato will be so happy! That is a nice looking young plant, by the way.
You could also use a bag of commercial soil that had fertiliser mixed with it. —Take out about half of the contents, and keep aside safely. —Plant your plantlet deeply, right up to the top 2-4 leaves ( strip all the rest off). —Poke holes in the bottom of the soil bag for drainage. —Add the soil that you have removed a bit at the time, after removing more leaves as the plant grows. —Once the soil bag is full, you only then have to sucker the plants as needed. —Feed your plant once it has begun flowering and has actually developed little marble- sized toms.
I have transplanted to a 30cm pot and now about 1.5m tall. Unfortunately there are only handful of tomatoes and not many flowers. What should I use to feed the cherry tomato plant?
After transplanting the plant will need about two weeks to recover. After that you can use some rose fertiliser every week or two. Actually any general fertilizer that has high potassium and phosphorus NPK numbers...such as, 6-24-24 or 8-32-16. It can be difficult to find the appropriate fertiliser, so just get what you can find. You can’t always find what you want, but sometimes you can find what you need.
