Ok, HERE is the planting article I started to write before I got distracted by the raised planting bed subject.
Only our peppers and tomato plants were started in the house and transplanted as seedlings, everything else I sowed directly into the garden as seed. The seed planting was fun with the kiddo, but I learned the hard way not to let her handle delicate new vegetable plants, even ones that have been well hardened off. She broke several before I found her an alternate job to do. I left the broken ones in their original plastic bottle containers. Maybe they’ll grow new leaves, maybe they won’t. As you can see from the pictures, I didn’t have any shortage of tomato plants, so I wasn’t too upset about the loss of a few.

These were the plants that I started from seed back in February or March. In the past couple weeks, when it FINALLY stopped snowing here and the night temperatures were above 50F, I began the process of hardening off the plants. Pepper plants shouldn’t be transplanted to the ground until the earth has warmed to at least 50F; to do so earlier could kill them or hinder their growth until warmer weather comes. Tomato plants are a bit more forgiving, but you have to cover or shelter them if there is any danger of frost.
Hardening seedlings off basically entails getting those house-protected seedlings acclimated to being outdoors in a less controlled environment. The absolute best time to put them out is a cloudy day with a slight breeze. The breeze helps the stems to stiffen up so they can support the plant’s top growth and the cloud cover helps keeps the sun from scorching them. They’ll love all that sun later, but when they first come out from inside, they are a bit sun-shy. If you don’t have cloud cover, just sit them in at least partial shade. I put mine out for a week before transplanting them to the garden, starting off with only a couple hours and working up to 6-8 hours a day. The day I planted was also partly cloudy, which was helpful to avoid a lot of stress during transplant.
I don’t use my plastic containers more than one season. I’m not absolutely sure whether or not those water or Gatorade bottles are BPA-free and since I’ve read that the chemicals can leach into soil or be absorbed by plants when the plastics begin to break down, I just cut them off the roots and toss them when I plant. Cutting them off also means I don’t have to disturb all those tiny little roots any more than absolutely necessary.

I dug the holes, making them deep enough to plant each seedling at least as deep as it had been in its container- deeper for all the tomatoes, since they will grow new roots along the buried stems. Soil additives are the perfect task for little helpers; I had a bowl full of crushed eggshells and another of used coffee grounds to add to each hole. I instructed my daughter to get a big handful of eggshells and put it in the bottom of each hole. Coffee is a good green soil additive and gives the plant a nitrogen boost; we followed the eggshells with a handful of coffee grounds.
I’ve planted my tomatoes with crushed eggshells since my first attempt at growing tomatoes resulted in about 25% of them getting blossom rot. Blossom rot is fairly common in tomato plants and can often be prevented with good watering practices and adding calcium to the soil. Since eggshells release their calcium slowly, I add some to the hole when planting and top-dress more around the plants throughout the season. You can also save water from boiling eggs, cool it and use it to water the plants. They are also a great slug and snail deterrent; they don’t like to drag their soft little bodies over all those sharp edges. I don’t add extra fertilizers or plant food to seedlings, since I already grow them in soil amended with Miracle Grow Garden Soil and home-made compost.
After my daughter broke several plants trying to separate them from each other, I put her on additive and seed planting duty so I could pull the delicate plants out of their containers- I told her this was a Mommy job since it required sharp scissors 😉 – once the plant was in place, I helped her scoop some dirt back into the hole and pat it down very gently (don’t break the stems) to hold them in place. If you have trellis or stakes to add, you’ll want to do it NOW while your plants are small, even though it may seem unnecessary until they actually need the support. Add it later; you may damage the roots when you jam the spikes or stakes into the ground or snap off the vines trying to weave them through your supports. I have a sort of permanent trellis attached to our house of thin, bendable wire. I originally planned these to support climbing roses, so they are quite strong and support cucumber and tomato plants well. I found I preferred them to cages, since they keep the plants spread out, the fruits are easier to get to, there are less areas for bugs to hide and plenty of air circulation to prevent fungus or mildew. Whatever you use, make sure it’s going to be strong enough to support fully mature plants with fruits on them. I was surprised at first how HEAVY they can actually get!

Since I was planting full size plants and not direct-sowing seeds, I went ahead and added mulch around the plants. Mulch really helps new seedlings retain moisture since they don’t have deep, established roots yet. The chunky pine mulch also helped some of my floppy plants stand up a bit straighter until their stems strengthen enough to support themselves. I skipped the mulch over the areas where we put just seed, to make sure the new seedlings are able to get enough light and heat to germinate. Once the plants are up and established, I’ll weed around them and add mulch then.

At the height of summer, it easily reaches the 100 degree mark here; I usually have to water at least every third or fourth day if there’s no rain to supplement. Too frequent watering won’t encourage your plants to develop deep roots and they will dry out quickly and have little support for bushy top growth. Soak them really well when you do water. Aside from this, there are really no hard and fast rules on watering; check your soil and watch your plants, a little common sense will tell you whether they are dry and need a drink or not. Morning and evenings have worked best from my experience; mid-day burns off quickly and seems to shock the plants that get doused with cold water when they’re really hot. I’ve read lots of advice about not getting the leaves wet because it causes fungal diseases, etc. This is fine advice if you can avoid it, but if you get the leaves wet, it’s not the end of the world. Rain doesn’t JUST water the roots of a plant when it falls.
It helps to plant things like lettuce, broccoli and other plants that bolt in hot weather behind your trellised plants to provide them with some shade. Our garden area gets blasted with full sun from around noon-thirty until 4-ish in the afternoon, so the sun really beats down during that part of the day. I’ve noticed that my tomato plants will look a bit wilted during the really brutal summer days, but they always perk back up in the evening when it cools off a bit. I’ve read somewhere that this is a normal defense-mechanism of the plant and nothing to get excited about.
So I guess that’s finally it for the starting plants from seed subject; since I’ve seen them from package into the garden and it’s all maintenance from here. I’ll try to remember and post at least a few photos of our garden once it is well established and producing. I’m keeping my fingers crossed for no beetle horror stories this year in the meanwhile, but we’ll see. 😉
