• When the soil is not too damp, rototill it.
• Add compost to improve soil drainage (air and water circulation).
• Add lime at a rate of 5 pounds per 100 square feet to boost the pH level.

When can I sow grass seed in Oregon during the spring?

In many regions of Oregon, the period between early May and around mid-June is an ideal season for planting. Early plantings germinate and develop slowly, therefore there is rarely a benefit to doing so. Planting later in the summer presents several issues.

Perennial Ryegrass – Perennial ryegrass works well with Kentucky bluegrass and resembles it in appearance. It does not handle hard winters as well as Kentucky bluegrass and fine fescue, but it thrives in mild summers and temperate winters. This makes perennial ryegrass one of the most popular alternatives for cold and humid climates like the Pacific Northwest.

Can grass be covered with topsoil and then reseeded?

If you’re seeking for a simple answer, then sure, you can place topsoil over grass and existing garden lawns. Although it is feasible for grass to grow through the dirt, success depends on the amount of topsoil that is put as a top dressing. Please note that prior to spreading dirt over existing grass, the grass must be mowed.

Kentucky bluegrass, colonial bentgrass, fine fescue, and perennial ryegrass are our selections for the finest turfgrasses for Portland. These cool-season grasses will flourish in the coastal environment of Portland.

What seeds may I sow in Portland, Oregon, at this time?

– Portland Nursery has NEVER sold genetically modified organism (GMO) seed. EVERY company from whom we acquire seeds has signed the Safe Seed Pledge. If you have more inquiries or concerns, please visit the Information Desk. We provide a wide variety of cover crop seed in bulk for spring and summer planting.

• After the risk of harsh frost has gone, spring and summer cover crops are planted.
• The typical date of the last frost in Portland is April 15) A cover crop is a fast-growing crop that is primarily intended to keep the soil covered for a brief period of time before being plowed under as “green manure” or removed and composted.

When the lush, full growth of green crops is put under, large quantities of organic matter are contributed to the soil. As humus, organic matter enhances soil texture and stabilizes moisture content. These plant nutrients are returned to the soil, transforming it into a nutrient reservoir.

1. Legume plants house nitrogen-fixing bacteria that take nitrogen from the air and transform it into a form that plants can use.
2. As a cover crop, legumes replenish the soil with nitrogen.
3. Deep-rooted cover crops include oilseed radish and fava bean.
4. Their taproot is exceptional in dissolving clay and other dense soils and creating much-needed airflow.

Planting cover crops in your garden will also function as “living mulch,” limiting erosion, nutrient loss through leaching, and weed development. Please refer to our Cover Crops Article for additional details. Indoors: Tomatoes, tomatillos, peppers, and eggplant are heat-loving summer vegetable crops that should be germinated inside.

1. Due to the mild and brief maritime summers in Portland, it is not advised to sow these crops directly into the soil.
2. You may also sow lettuce and members of the Brassica family, including broccoli, Brussels sprouts, cabbage, cauliflower, kale, and kohlrabi.
3. Some edible cool-season plants can be direct-seeded in the garden before Portland’s typical last frost date (April 15).

In March, you can direct plant arugula, Asian greens, cilantro, green onions, mustard greens, parsley, peas, radishes, spinach, and Swiss chard seeds. March and April are the best months for direct sowing salad greens that appreciate chilly temperatures, including cress, dandelion greens, endive, mesclun mix, radicchio, and sorrel.

Mid-to-late April is the time to start seeds for cucumbers, summer and winter squash, pumpkins, and melons inside. These plants will produce higher harvests in Portland if they are put outside as seedlings as opposed to being sown directly into the garden.

Some edible cool-season plants can be direct-seeded in the garden before Portland’s typical last frost date (April 15). Before April 15, you can sow these seeds directly: Asian greens, cilantro, green onions, kale, mustard greens, parsley, peas, radishes, spinach, Swiss chard, and turnips are included.

After April 15, beets, broccoli, Brussels sprouts, cabbage, carrots, cauliflower, celeriac, chives, dill, bulb fennel, kohlrabi, sunflowers, and scarlet runner beans can be planted directly. This is also the season to sow decorative sweet peas for incredibly fragrant spring blossoms.

Late in June, I still had one empty bed in my vegetable garden. What am I to plant? Here is a summary of the many early summer planting options. Since previous harvests may soon bolt, add extra cilantro and dill to the vegetable garden, as well as a third cycle of salad greens (varieties of lettuce that resist bolting include Jericho, Lollo Rosso, Merlot, Oakleaf kinds, and Red Sails).

• Plus Arugula ‘Sylvetta’).
• There is still time to grow summer crops, with a little over 100 days remaining until the typical first frost date.
• Basil, green beans, maize, cucumbers, and summer squash may be grown from seeds or seedlings.
• If planted by the end of June, tomatoes, peppers, and eggplant in one-gallon containers or with fewer than 65 days to maturity will begin producing in September.

The final week of June is also the final opportunity to plant melons, pumpkins, sweet potatoes, and winter squash. Some popular crops, such beets, carrots (keep them wet), parsnips, and rutabaga, are best direct-seeded in June and July for harvest in the fall.

One bed is insufficient to accommodate all possible outcomes. If you have a bed loaded with garlic, onions, or shallots, you may grow Brussels sprouts, broccoli, cauliflower, cabbage, kale, and chard in that space in July. Fall and winter are likely the furthest things from your mind as you prepare your summer watering schedule and anticipate harvesting your first crop of tomatoes.

However, now is the time to begin planning and planting seeds for fall and over-winter harvests! You’ll discover that enjoying the delightful pleasure of freshly selected veggies throughout the cooler months is well worth the effort, time, and planning, and July is the ideal time to sow the seeds for winter root crops such as turnips, parsnips, beets, rutabagas, and carrots.
