First Tomatoes Planted Out

I have been planting tomatoes out in April for quite a few years since discovering plastic double-walled tunnels.  I looked at 30 year temperature lows for April and there was only 2-3 degrees difference between April 1 and 15, so even tried moving the date to April 1, but this year I didn't get plants hardened off early so planted some out on April 15.  They had gotten too tall for my 11" light shelf clearances, so went into my aquaponics grow bed transplanted into 4" pots for several weeks, and got rather leggy there.   I harden them off on my east-facing concrete front porch, where the morning sun doesn't burn the delicate foliage and the concrete acts as a heat sink.
I left them there for a week.  Meanwhile, I was killing weeds with newspaper and keeping the rain off the rows with my tunnels.   So on planting day, I removed those and used my mattock for remaining weeds to clear the row, and dug holes one spade deep and 2' apart.  My amendments include aged rabbit manure, top, and clock-wise compost, lime, glacial rock dust, and red lava rock, which goes into the bottom and sides of the holes to protect the plants from moles and voles, as they don't like the scratchy texture.
The plants are too tall for the tunnel so I perhaps should have planted them deeper, but will lean them for a while until things warm up.   In the past I have had snow and frosts on the tunnels without injury to the tomatoes.  The first ones I plant out always have fruit earlier than later ones in spite of the cold, so it gives me a jump on the season with at least a few plants.

I went through several years of extensive tomato trials of 60-100 different heirloom along with a few commercial or hybrid varieties,  and found some I liked, but many were in the 72 and up DTM (Days to Maturity) range, which here can be 2 times as long.  After 2 years of very cold June and July temperatures, in addition to our usual cold summer night temps, near 50 degrees F, I decided the only way to make it worthwhile to do all the work was switch to early varieties and also a number of determinate varieties that don't require as much support and time-consuming tying up.

The 3 varieties going out first are Juliet (F? saved) vigorous producer of small paste cherries; Jetsetter, very early and productive small, round and blemish-free; and progeny from what was supposed to be Napoli but wasn't, but was a great little tomato last year, blemish-free, productive and in clusters.  I hope its offspring will resemble it-

Plants I am continuing to transplant and harden off will be New Big Dwarf, a rugose good producer; Legend, taller but late blight resistant, nice blemish-free round slicers;  Martino's Roma, determinate and productive paste tomato; old favorite Verna's Orange Oxheart, wonderful fruity heart with that delectable meaty texture; Lucky Cross as a gamble because last time I tried they didn't come true, but it is a luscious bicolor, longer DTM; and a saved paste which may have San Marzano as a parent.

The experiment I tried last year interplanting bush beans with tomatoes and eggplants, utilizing the poisonous quality of the nightshades to potentially repel the voles, seemed to work great with little damage to any beans or plants, so I will repeat that again, which is another motivation to plant short determinate tomatoes that won't shade the beans as much.
Planted row-
After planting, they were tucked under the tunnel (TunLCover brand) and should have had some Iron Phosphate slug bait applied but I couldn't find any, so they are taking their chances with the slugs.  I will have to hand-water until I get soaker hoses installed, and mulch with dried grass clippings, to keep in the water and smother the weeds.

Back to transplanting,  Hannah

  1. Hmm...Interesting idea of planting the bush beans with the tomatoes. I may give that a try.

    1. I thought it worked well last year, I'm going to try it again. Do you have voles or other tunneling pests that eat your beans?

  2. This is amazing considering you're in Colorado. I'll follow along and see how things go. You'll most likely have tomatoes before me. :)

    1. My "About Me" must be misleading, I went to school in Colorado many years ago but live presently in the Pacific Northwest, where the winters are really quite mild for being so far north. We get lows in the 20's and even as low as 6* F since I've lived here, but nothing like Denver that got down to -16* below 0* in January. I don't miss the untimely snowfalls early in fall and late in spring, but I had rich riverbottom soil there that did yield lots of tomatoes and squash.

  3. A really interesting post as I struggle with tomatoes in my polytunnel, no hope of growing them outside. How far north are you?

    1. I live near Portland OR, but at a higher elevation. I've been using TunLCovers for years and they really give plants a boost during the colder spring months. Squash do great under them too. I'm not sure how they differ from a polytunnel but the walls are double. Mulching with black plastic would probably also help but for me might also encourage voles too much.

  4. How did Legend do for you? I am definitely considering growing this variety!
