well I'm just following the recommended application rate, around a a teaspoon per L. The hedge is behind the tomato bed too, they do need to be trimmed back because its creating shade in the tomato bed.applestar wrote:Is the hedge behind the tomato bed, too? Tomatoes will grow well at 5-10 Â°F lower temps than peppers and cukes.
...the 15-30-30 fertilizer -- how are you applying it? Every two weeks seem extreme. Those are pretty high numbers too, though maybe it just seems that way to me because I only use organic and I put some in the bed at prep and maybe a little more when planting, then not again until blooming. I do supplement weakly with other things I suppose.
well all those plants were bought from a local nursery so I didnt start from seed. I'm starting to think its the way I transplanted them. the cucumber seedlings were 4 per pot so I had to separate them, potentially damaging the roots a bit.imafan26 wrote:15-30-30 is miracle grow. It is a fast release fertilizer not for seeds. It is usually 1 tablespoon per gallon or a little less than a teaspoon per liter. But should be fed only once every two weeks but in reality you could do it once a month and it will still be fine. You may have fertilized too soon and actually prevented germination with too much nitrogen. In the beginning squash and cumber take a little bit to grow because the roots grow first before the top. It doesn't look like much is happening because most of the action takes place underground. If the top growth looks healthy you just need patience grasshopper. It should be growing faster by now. MIne are only slow for the first 3-4 weeks before the top starts to take off. So your cucumbers may be just needing a little more time. Peppers are slow the first couple of months for the same reason, the roots grow first. I don't grow ground cherries.
You will have to let some of the fertilizer leach out. Transplants may grow if you start them in pots without fertilizer and put more compost in the garden to try to dilute it out a bit. Add about 4 inches to the bed and mix it in.
Hold off on the fertilizing until you see some growth developing and only fertilize once a month or what we do is weakly weekly. 1/4 strength solution every week for three weeks and the last week only water to leach out the excess salts.
Usually people pick a day they can remember like Wednesday and do the fertilizing on Wednesday mornings when the stomata are open. And select like the first week to be water only. In 5 week months, add an extra week of water only.
Once the plants have matured, back off to once a month feedings only. Otherwise too much nitrogen will give you growth at the expense of bloom and fruit.
I would get a soil test before you plant in the next rotation or in the fall so you can plan amend for the Spring garden. Water soluble food is expensive and leaches readily.
A soil test will tell you how much and what kind of fertilizer to apply. You may find that you have enough phosphorus and potassium and you only need to add nitrogen or correct the pH. The more organics like compost and slow release fertilizers you use, the less fertilizer you will need to add over time.
