" Although it's often tempting to plant tender annuals like basil, petunias and zinnias, do so only if you can protect them from late freezes. April 29 is the average date for the Rogue Valley's last frost, and freezes can occur through mid-May.
" To harden off those tender seedlings, place them outside for increasing periods each day, but keep them in a sheltered area at night. After 7 to 10 days, they are ready to go into the garden.
" Start planting your containers with hardy starts like alyssum, pansies and sage. Leave room for tender annuals to add next month, like begonias and coleus.
" Adding water-absorbent polymer pellets to your soil mix will lengthen the time between summer watering.
" Many summer flowers can be grown from seed. Plant these at the beginning of the month, and your babies will be ready to plant in mid-May.
" Make sure your pond is clear of dead plant material. This will help minimize algae blooms as the water warms. You can also add beneficial bacterial to warming water. Fish feeding should resume when the water temperature reaches 50 degrees.
Kitchen Garden and Orchard
" Seeds: Get beets, chard, chives, kale and lettuce into the ground. Early planting means you can plant a second crop in these areas.
" Plant leeks for winter harvest; onion for summer eating and storage. Onions should be "long day" or "intermediate day" types, or bulb development will be disappointing. Try 'Cippolini,' 'Walla Walla' and 'Stockton Red.'
" Plant potatoes in a variety of colors, sizes and densities: 'Yukon Gold,' 'All Blue,' and 'Burbank Russet.'
" Fertilize established artichoke plants with a high phosphorus fertilizer to stimulate flower development.
" Another container idea: create a "tower" for your herb plants. In the largest container, bury a second pot about half-way in the center of the first, or place it at an edge if you plan to keep your herb "garden" against a wall. Depending on pot size, put parsley, sage, oregano, mint, thyme or rosemary in the bottom pot. Basil, cilantro or chives can grow above.
" As the soil begins to dry out, compacted lawns can be aerated. Add about 1/4-inch of compost to these lawns. Fertilize established lawns carefully, following package instructions with precision.
" Overseed thin lawns or bare patches. Water as needed, so seeds can sprout and get a foothold before summer heat. No fertilizer is needed in these areas until growth is established.
