Vegetables

1. Vegetables

2. Soil Preparation • Turn over soil in fall • Add organic matter in fall • On sandy soils turn in spring • May need to remove sod • Don’t work soil if wet • Organic soil amendments – 25-50% • Add N if using a high C material

3. Fertilizers • Organic • Refer to handouts for N:P:K analysis • Improve soil texture • Add nutrients • Increases water retention in sandy soils • Increases drainage in clay • Tends to be heavy • Slow release of nutrients • Will rot away in 1-2 years

4. Fertilizers • Inorganic • Does not change soil texture • Nutrients are easily leached • Easy to ship and use • Less work • Can be expensive • If selling produce, you can’t get a premium price.

5. Planting Time • Plant very hardy veggies when soil can be worked (soil temp 40F) • Asparagus Turnip • Peas Broccoli Radish Brussels sprouts • Rhubarb cabbage • Rutabaga celery • Spinach Garlic

6. Hardy veggies 45-50F • Beets • Carrots • Cauliflower • Lettuce • Parsley • Parsnip • Swiss chard

7. Tender veggies 60-65F • Beans • Tomatoes • Cantaloupe • Watermelon • Corn, Cucumbers • Eggplant • Peppers • Pumpkin • squash

8. Small seed ( carrot) ¼-1/2 inch deep Large seed ( beans) 1-2 inches deep Seed planting depth

9. Conserves moisture Can increase soil temperatures Can reduce soil temp Stops weeds Reduce disease Keeps crops clean Adds organic mater to the soil Can be a great home for slugs  Voles can live under or in it Don’t mulch tender crops until july Mulch

10. Mulch • Plastic • Clear plastic heats soil • Black plastic does not heat soil very much • Black plastic is usually paired with drip irrigation • It’s a lot of non-recyclable garbage at the end of the season • Organic • Insulates soil – don’t mulch too early • Use material that is weed free ( straw ok, hay has lots of seed) • When it rots it can steal N from crops. • Can be tilled in after the growing season • Be aware of C:N ratios

11. Mulch is best under: • Tomatoes –red or black plastic • Peppers – silver/reflective mulch • Eggplant • Sweet corn – let pumpkin leaves be the mulch Potatoes • Cucumbers • Melons/squash

12. Plastic mulch

13. DEER

14. Deer can wipe out a garden Protect your garden! • Fence ( electric or tall), Cage, visual • Repellants • Plantskydd • Rotten eggs, Bitters • Guard Dogs • Kill the deer

15. Weed Control • Vegetables yield best with no competition • Hoe/ till • Mulch • Fire • Vinegar (1gal vinegar +1qt lemon juice) • Herbicide

16. Apiaceae

17. Apiaceae • Carrots • Plant early • Seeds take 12 days to emerge • Can be gel seeded • Store in cool-cold place. Cut shoulders, don’t wash, separate layers with newspaper. Don’t let them dry out • Parsnip • Low seed germination • Plant seed and wait • Very sweet after frost • Fewer calories than carrots and sweeter • Store like carrots

18. Cabbage Family Brassicaceae

19. Brassicaceae • Broc/cauliflower • Start seeds indoors in March/April • Plant out mid May • Cover Broc with row cover to keep moths off • Side dress with N mid season • Cut crowns before they bloom • Raddish • Plant early and pull when big enough • can use there to space other seeded crops

20. Asteraceae\ Lettuce

21. Asteraceae\ Lettuce • Lettuce is a cool season crop that can be started ahead and planted by transplant or direct seeded • Several crops of lettuce can be grown in a summer • Mesclun – is a lettuce mix cut as seedlings. • Can be cut many times

22. Chenopodiaceae

23. Chenopodiaceae • Beets and Chard • Beets are planted in cool soil • Can be picked young and small or large • Know your cultivar • Root and leaf are eaten • Chard is a beet grown for the leaves • Usually started as a transplant • Give them room as each plant gets large • Very frost resistant so the fall leaves often have the best flavor

24. Poaceae • Plant corn in blocks • To prevent lodging • And insure pollination • Can be direct seeded • Corn can be transplanted • Best in peat pots • High N crop • side dress mid season

25. Onion Family Liliaceae

26. Liliaceae/ allium crops • Garlic • great for Duluth • Plant in Sept/Oct • Don’t let it have wet feet • Remove flower scapes • Pull when 50% of leaf is yellow ~Aug 1 • Dry bulbs in shade • Onions – seedlings or bulblets • Plant seeds Feb indoors • Or buy tiny bulbs and plant Apr-May – as soon as soil can be worked • Pull when tops fall, dry in shade, Store in cool place

27. Cucumber family Cucurbitaceae

28. Squash • When there is a choice…. • Grow bush types to save space • Mulch to keep clean • Mouse control

29. Solanaceae

30. Solanaceae • Tender plants (except spuds) • Start 12 weeks early & transplant • Look for cv with resistance to deseases • Determinate or indeterminate? • Even watering • Full sun • Self fertile But bees help

31. Fabaceae

32. Fabaceae • Peas are hardy so plant early • Fava beans can also be planted in cool soil • Green beans are tender and need warm soil • Self fertile • Use inoculants • Do not walk in them if leaves are wet • Beans can continue to bear if the beans are picked

33. Crop Rotation • Rotation by Plant Family • Solanaceae • Tomato, potato, eggplant, tomatillo, peppers • Apiaceae • Carrot, parsnip, parsley, celery, dill, lovage, celariac • Fabaceae • Beans, peas • Liliaceae • Onion, garlic , leek • Brassicaceae • Broccoli, Cauliflower, kohlrabi, radish, kale, cabbage • Chenopodiaceae • Beets, chard • Asteraceae • Lettuce • Poaceae • Corn • Cucurbitaceae • Squash, cucumber, melon

36. Crop Rotation

37. Seed starting and Season Extend • Heated • Greenhouse • Hot bed • Under lights in your house • row cover • Clear plastic mulch • Cold frame • High tunnel
