I have a pot of radish seeds to start in zone 10 and i‘ve read that peat moss was wonderful so I thought why not use all of it in the pot and get awesome radishes?. I thought it was the best idea, so I planted my seeds (and a baby tree) entirely in peat moss and added plant food (sea kelp). Was that a great idea?
It should only be used at the germination stage and you need to keep the peat moist at all times or it will desiccate and possible ruin any beginning roots or softer seed. You also should never fertilize unsprouted seeds or seedlings before they've grown at least 2 sets of true leaves. So, bad idea on the tree unless you made a soil blend with peat and other stuff like compost or manure. Also, bad idea fertilizing your seeds before they're due. Finally, peat moss is not all that wonderful. It is completely devoid of nutrients and it's not exactly a renewable substance since it has to be imported from Canada or Europe. Coco coir and compost are much better options, for future reference, esp if you mix with sand or perlite. Good luck, though.
The trouble with peat is that it runs water and gets hard as a rock when it drys. It is hard to keep a constant level of moisture in peat. Peat moss it also acidic. Using peat to loosen soil in a garden also adds organic matter to the soil. It doesn't clump because soil is in between the particles.
No not a good idea. Peat is good when used with 1/3 peat, 1/3 compost and 1/3 vermiculite. so you planted a bunch of radish seeds and a tree in the same pot. You did not mention the size of the pot. You have over crowded. The radish will not have room to develop and the tree will rob young plants of moisture and nutrients. Seeds/seedling do not need nor will they benefit from fertilizer before they have 2 or 3 sets of true leaves. You have several issues - poor growing medium, over crowding and unnecessary fertilization. Sorry but it may be a good idea to start over. Radish is much better planted in the ground. If you must container plant get a few of those long narrow window box planters for your radish. Make a good soil mix as mentioned above or get all purpose potting soil. Plant your allow seed for every 2 square inches. Keep evenly moist and warm. Once the seeds germinate they need full sun 6 -8 hours per day. Do not over water or use plant saucers - take off the ones that come on the containers. That is a good way to get root rot. As for the tree identify it and you can get some help on how to plant and care for it. Good luck
