Transplant out
- Tomatoaround Jun 13
Safe to set out 2 weeks after last frost. Bury 2/3 of the transplant stem. Roots form along the buried stem for a stronger plant.
- Basilaround Jun 13
Safe to set out 2 weeks after last frost. Pinch flower spikes the moment you see them: leaves stay sweet all season.
- Brussels Sproutsaround Jun 13
Safe to set out 2 weeks after last frost. This is a fall crop: frost is what turns the sprouts sweet. Around 4 weeks before harvest, top the growing tip so the plant pushes size into the sprouts.
- Pumpkinaround Jun 13
Safe to set out 2 weeks after last frost. Count back 100 days from your first frost to time a Halloween harvest. Cure cut pumpkins in the sun for 10 days and leave 3 in of stem so they store for months.
- Summer Savoryaround Jun 13
Safe to set out 2 weeks after last frost. Harvest just before flowering for the best flavor, then shear the whole plant back for a second flush.
- Lovagearound Jun 13
Safe to set out 2 weeks after last frost. Grows 4-6 ft tall once established; give it the back of the bed and divide the crown every few years to keep it productive.
- Catniparound Jun 13
Safe to set out 2 weeks after last frost. Fence it off if cats roam the neighborhood: they'll flatten the plant and any seedlings around it rolling in the scent.
- Elderberryaround Jun 13
Safe to set out 2 weeks after last frost. Plant two different cultivars for better fruit set; cut clusters when berries turn deep purple-black and cook before eating, never raw.
- Black Currantaround Jun 13
Safe to set out 2 weeks after last frost. Check state rules before planting: currants can be restricted near white pine stands due to blister rust; resistant cultivars exist where it's allowed.
- Gooseberryaround Jun 13
Safe to set out 2 weeks after last frost. Prune to an open vase shape each dormant season; good airflow through the center is the best defense against mildew.
- Aronia (Black Chokeberry)around Jun 13
Safe to set out 2 weeks after last frost. Fruit looks ripe well before it's ready; wait until berries turn nearly black and soften slightly to avoid the sharp astringency of early picking.
- Honeyberry (Haskap)around Jun 13
Safe to set out 2 weeks after last frost. Plant two different cultivars for pollination; it flowers and fruits earlier than almost any other berry, often before strawberries.
- Seaberry (Sea Buckthorn)around Jun 13
Safe to set out 2 weeks after last frost. Needs one male plant for every 6-8 females to fruit; the branches are thorny, so many growers cut whole fruited branches to harvest rather than pick berry by berry.
- Cranberryaround Jun 13
Safe to set out 2 weeks after last frost. Needs boggy, acidic soil, pH 4-5; without a naturally wet, peaty spot, grow it in a lined bed you can flood periodically.
- Lingonberryaround Jun 13
Safe to set out 2 weeks after last frost. Mulch with pine needles or peat to hold the acidic soil pH it needs; it can produce two crops a year in longer seasons.
- Serviceberry (Juneberry)around Jun 13
Safe to set out 2 weeks after last frost. Netting is close to mandatory: birds often strip a tree bare within a day or two of the berries ripening.
- Chokecherryaround Jun 13
Safe to set out 2 weeks after last frost. Leaves, twigs, and pits contain cyanogenic compounds and are toxic to people and livestock. Use only the cooked, strained pulp, and keep wilted prunings away from animals.
- Highbush Cranberryaround Jun 13
Safe to set out 2 weeks after last frost. Fruit is sour and best after frost; buy the American species rather than the European lookalike, whose fruit is bitter and far less useful.
- Sweet Potatoaround Jun 20
Safe to set out 3 weeks after last frost. Plant rooted slips, not seed. Wait until soil holds 65F, then let vines sprawl and cure roots at 80F for 10 days before storage: that curing step is what makes them sweet.
Garden care
- Mulch every bedaround Jun 20
3-4 in of straw or leaves now holds water, blocks weeds, and cools roots for the whole summer.
- Set up deep wateringaround Jun 27
Switch to fewer, longer soaks (1-1.5 in/week at the root) instead of daily sprinkles.
Succession sow
- Bush beanaround Jun 27
Sowing 2: replant every 14 days so one planting never has to feed you all season.
